Business Finance Between Project Milestone Payments UK: Working Capital, Funding Options and Eligibility
Business finance between project milestone payments can help UK companies cover payroll, materials, subcontractors and operating expenses while waiting to receive the next payment under a customer contract.
For many project-based businesses, the challenge is not necessarily a lack of profitable work. It is the delay between paying the costs of completing that work and receiving the next instalment from the customer.
A construction contractor might need to pay workers and suppliers for several weeks before its next certified payment becomes due. An engineering company may need to purchase components before reaching a production milestone. An IT consultancy might complete substantial development work before receiving payment after customer acceptance.
UK businesses may be able to finance these cash-flow gaps through working capital loans, revolving credit facilities, specialist construction finance, invoice finance, purchase order finance and other appropriate commercial funding arrangements.
However, a signed project contract does not automatically guarantee financing.
Lenders may distinguish between work that has been completed, amounts formally approved for payment, valid outstanding invoices and revenue expected from future milestones.
This distinction can substantially affect how much funding is available.
This guide explains how milestone payment financing works in the United Kingdom in 2026, which financing structures may be appropriate, what lenders consider during underwriting and how to calculate the actual cash required between project payments.
What Is Business Finance Between Project Milestone Payments?
Business finance between project milestone payments is commercial funding used to cover eligible expenses during the period between cash leaving a business to perform contractual work and payments arriving from the customer.
A project milestone is a defined stage or event that may trigger a contractual payment.
Depending on the agreement, milestones can include:
- Completion of a specified percentage of construction work.
- Delivery of materials or equipment.
- Completion of manufacturing or assembly.
- Installation and commissioning.
- Acceptance of software or technical deliverables.
- Achievement of agreed engineering or project stages.
- Practical completion or final customer acceptance.
A business may have to incur substantial expenditure before it is entitled to receive payment for the next stage.
For example, a mechanical engineering contractor may be required to purchase £40,000 of materials and pay £25,000 in labour before receiving a £100,000 customer milestone payment.
That creates a temporary requirement for working capital.
However, the exact funding requirement depends on the company's available cash, other expenses and the timing of contractual payments.
The purpose of milestone finance is to support a defined cash-flow gap, not to treat the entire uncompleted contract value as immediately available money.
Can You Get a Business Loan Before the Next Project Milestone Is Paid?
Yes, potentially.
Some UK commercial lenders may consider businesses that need funding before receiving their next project payment.
Approval depends on the borrower, lender, product and underlying transaction.
A conventional working capital lender may assess the company's established cash flow and ability to make repayments.
A specialist construction finance provider may examine contract documentation, applications for payment, valuations and certified sums.
An invoice finance provider may require an eligible invoice arising from completed work.
A purchase order finance provider may consider qualifying supplier payments linked to a confirmed customer order.
These providers do not necessarily evaluate the same contractual evidence.
For example, a signed £250,000 contract provides useful evidence of a commercial opportunity, but it does not prove that £250,000 is currently due and payable.
The customer may not have accepted the work, the next milestone may not have been reached, or the contract may permit adjustments.
The British Business Bank's purchase order financing guidance explains that some specialist finance structures can provide support before goods are delivered, while invoice finance generally relies on qualifying receivables.
Whether the business can borrow before a milestone is reached depends on the type of financing, not simply the existence of a project contract.
Why Project-Based Businesses Experience Cash-Flow Gaps
Project-based companies can experience considerable variations in cash receipts and operating expenses.
Unlike businesses receiving consistent daily sales or monthly retainers, they may collect substantial amounts at relatively infrequent intervals.
Paying Employees Before Customers Pay
Workers often need to be paid weekly or monthly.
However, a project's payment milestones might occur every six to eight weeks.
A construction firm, engineering business or software consultancy may therefore have significant payroll obligations between incoming payments.
Purchasing Materials Upfront
Project delivery can require substantial supplier expenditure.
Examples include structural steel, electrical components, specialist machinery, timber, packaging materials, IT hardware and other products.
Suppliers may require deposits or payment before delivery.
The contractor may not receive its corresponding customer payment until those materials have been installed, tested or accepted.
Paying Subcontractors
Main contractors and specialist service businesses may engage subcontractors to complete specific parts of a project.
Those subcontractors may have different payment terms from the main customer.
If subcontractor payments fall due before the customer's next milestone, the business needs sufficient liquidity to meet both obligations.
Milestone Certification Delays
Some contracts require work to be inspected, valued or certified before payment becomes due.
Completion of the physical work and approval of the corresponding payment can happen on different dates.
For example, a construction company may finish the required work on the 15th of the month but not receive a certified valuation until later.
The actual cash payment may arrive after the contractual payment period.
Customer Approval and Acceptance
IT, engineering, manufacturing and installation contracts may require the customer to approve deliverables.
If the customer identifies deficiencies, requests corrections or disputes whether the milestone has been completed, payment may be delayed.
A business should not treat an expected acceptance date as guaranteed cash.
Retention Payments
Certain construction contracts permit a portion of the amount otherwise payable to be retained until later contractual conditions are satisfied.
These amounts may be released after practical completion, the end of a defects period or another specified event.
A retention balance can therefore remain outstanding well after the main work is finished.
The value retained should be distinguished from money immediately due for payment.
Worked Example: Financing a £180,000 Project Between Milestone Payments
Consider a hypothetical UK commercial engineering contractor based in Birmingham.
The company wins a £180,000 project involving equipment installation, fabrication and specialist subcontracted work.
The customer agrees to make payments at defined project stages.
The company expects the work to run for approximately 130 days.
For simplicity, all figures exclude VAT, assume the contractual payment conditions are satisfied and use actual cash receipts rather than merely invoiced revenue.
Step 1: Establish the Customer Payment Schedule
The £180,000 contract is divided into four payments.
Initial project deposit: £27,000 on day zero.
First milestone payment: £63,000 on day 70.
Second milestone payment: £54,000 on day 100.
Final completion payment: £36,000 on day 130.
The total is:
£27,000 + £63,000 + £54,000 + £36,000 = £180,000.
The payment dates are illustrative.
In a real contract, the dates must reflect the applicable acceptance, invoicing, notice and payment provisions.
Step 2: Calculate Project Expenditure
Assume the contractor expects the following direct cash costs.
On day zero, £20,000 is paid for initial materials.
On day 15, £22,000 is paid in labour costs.
On day 30, another £36,000 is paid to material suppliers.
On day 50, £24,000 is paid in labour costs.
On day 55, £18,000 is paid to subcontractors.
On day 80, £26,000 is paid for installation and other project delivery costs.
On day 110, another £10,000 is spent on testing, completion and final project work.
Total direct project expenditure is:
£20,000 + £22,000 + £36,000 + £24,000 + £18,000 + £26,000 + £10,000 = £156,000.
Before financing costs and general business overheads, the project is expected to generate:
£180,000 − £156,000 = £24,000.
That represents an illustrative direct project contribution margin of approximately 13.3%.
However, it does not mean the business will have enough cash at every stage of the project.
Step 3: Calculate the Cash Position Before the First Milestone
At the start of the project, the contractor receives £27,000 and pays £20,000 for materials.
The project has £7,000 of positive cumulative cash flow at that point.
By day 15, another £22,000 has been paid for labour.
The cumulative project cash position becomes negative £15,000.
By day 30, the company pays another £36,000 for materials.
The cumulative deficit increases to £51,000.
By day 50, after a further £24,000 labour payment, the deficit reaches £75,000.
By day 55, the contractor pays £18,000 to subcontractors.
The cumulative project cash shortfall now reaches £93,000.
The business has incurred £120,000 in direct project expenditure but received only the £27,000 initial deposit.
Step 4: Calculate the Position After the First Milestone
On day 70, the contractor receives its expected £63,000 milestone payment.
The cumulative project shortfall decreases from £93,000 to £30,000.
However, the business is not yet cash-positive.
On day 80, it spends another £26,000 on project work.
The cumulative deficit increases again to £56,000.
The second milestone payment of £54,000 arrives on day 100.
That reduces the cumulative deficit to £2,000.
A further £10,000 in project expenses on day 110 increases the shortfall to £12,000.
Finally, the customer pays the £36,000 completion balance on day 130.
The project then finishes with the expected £24,000 contribution before financing costs and general overheads.
Step 5: Determine How Much Financing Is Actually Needed
The contract value is £180,000.
The expected direct project expenditure is £156,000.
However, the largest cumulative cash shortfall is only £93,000.
The financing requirement should therefore be evaluated against the £93,000 peak project cash gap, not automatically the £180,000 contract value.
In practice, the contractor may also require additional liquidity for VAT timing, financing fees, unexpected expenses, general overheads and delays.
For illustration, assume it investigates a £100,000 working capital facility.
That would exceed the forecast project cash shortfall by £7,000 before financing charges.
Whether the amount is sufficient depends on how the facility operates and whether fees are deducted or payable separately.
Step 6: Calculate an Illustrative Financing Cost
Suppose a lender provides a £100,000 bridge facility.
Assume the entire amount is advanced on day zero, even though some money will not be needed until later.
The following hypothetical terms apply:
- Principal advanced: £100,000.
- Nominal annual interest rate: 12%.
- Interest method: Simple interest on the principal outstanding.
- Financing period: 130 days.
- Day-count convention: Actual/365.
- Arrangement fee: 1.5%, paid separately.
- Principal and accrued interest: Repaid at maturity.
- Additional charges: None.
The interest calculation is:
£100,000 × 12% × 130 ÷ 365 = £4,273.97.
The arrangement fee equals:
£100,000 × 1.5% = £1,500.
The total illustrative financing cost is:
£5,773.97.
After deducting that financing cost from the £24,000 project contribution, approximately £18,226 remains before general business overheads, taxes and other unbudgeted expenses.
These are hypothetical terms, not a verified lender offer or representative market rate.
The arrangement fee is assumed to be paid from separate business funds, not deducted from the £100,000 advance.
Step 7: What Happens if the Final Milestone Is Delayed?
Assume the customer pays the final £36,000 on day 160 instead of day 130.
The final receipt has been delayed by 30 days.
If the lender agrees to extend the facility for the additional period without changing the other terms, the extra illustrative interest on £100,000 would be:
£100,000 × 12% × 30 ÷ 365 = £986.30.
The total interest expense increases.
However, this calculation assumes an extension is available.
In reality, the lender could require repayment on the original maturity date or impose additional fees, default charges or other conditions.
A company should not assume it can automatically extend a bridge loan whenever a customer delays payment.
What the Worked Example Demonstrates
A profitable project can create substantial working capital pressure before generating positive cash flow.
The contractor expects £24,000 in direct contribution but must finance a peak cumulative cash shortfall of £93,000.
The appropriate financing arrangement depends on when the funds are needed and when customer payments become available.
A revolving facility that permits staged drawdowns may produce different interest costs from a loan fully advanced at the beginning.
However, facility charges, commitment fees and other terms also matter.
The important calculation is the amount of cash required at the worst point in the project, plus an appropriate allowance for timing risks and other obligations.
Business Finance Options Between Project Milestones UK
Project-based businesses have several potential financing options.
Different products support different stages of the contract.
1. Short-Term Working Capital Loans
A short-term business loan provides an agreed amount that the business repays according to its financing contract.
It may be appropriate where a company has a temporary project-related funding requirement and a realistic repayment source.
For example, an established engineering contractor might borrow £50,000 to pay suppliers before collecting a significant customer milestone.
The lender will assess the company's overall financial position and ability to repay.
A contract showing expected future payments may support the application, but the lender may also consider existing cash flow, other customers and alternative repayment sources.
A short-term loan can be risky where repayment depends entirely on an uncertain milestone.
The company should establish what happens if the customer delays acceptance, reduces the payment or disputes the work.
2. Revolving Business Lines of Credit
A revolving credit facility can be useful when funding requirements repeatedly increase and decrease throughout a project's life.
The borrower generally receives an approved limit and may draw funds as required, subject to the facility terms.
For example, a contractor could use the facility to cover material purchases, reduce the balance when a milestone is paid and draw again when the next phase of work begins.
Interest may be charged on the amount utilised, although commitment fees, renewal charges and other expenses can apply.
This structure may suit businesses delivering several overlapping projects.
However, the lender may require security, periodic reviews and financial reporting.
The facility may also be reduced or cancelled according to the contract.
3. Invoice Finance
Invoice finance allows qualifying businesses to obtain an advance against eligible unpaid commercial invoices.
This can be relevant after the business completes a project milestone and raises a valid invoice.
For example, a consultancy might complete an agreed software implementation phase and issue a £60,000 invoice.
If the customer has accepted the work and the invoice satisfies the finance provider's eligibility requirements, the consultancy may be able to obtain an advance before the customer pays.
According to the British Business Bank, invoice finance providers commonly advance approximately 80% to 90% of eligible invoice values, although actual rates and conditions differ.
At an illustrative 80% advance rate, a fully eligible £60,000 invoice could support a £48,000 advance before fees or other adjustments.
However, an invoice that is disputed or dependent on unfinished work may not qualify.
Official source: British Business Bank — Invoice Finance.
4. Specialist Construction Finance
Construction finance providers may consider commercial funding arrangements linked to applications for payment, certified valuations and eligible contract receivables.
This differs from ordinary invoice financing.
Some providers accept only qualifying invoices or certified amounts.
Others may consider certain uncertified applications for payment, subject to additional review and reserves.
For example, Bibby Financial Services publicly describes specialist construction funding that can consider applications for payment as well as invoices, including certain certified and uncertified amounts.
This is an example of a published financing product, not a recommendation or confirmation of a funding relationship with Mehmi Financial Group.
Construction finance may involve detailed examination of the payment application, valuation, retention, notices and customer payment history.
A submitted application for payment is not automatically an approved debt or guaranteed source of financing.
5. Purchase Order Finance
Purchase order finance may help eligible businesses purchase goods or materials needed to fulfil a confirmed commercial customer order.
For example, a distributor might receive a £120,000 customer order but require £75,000 to purchase goods from a supplier.
A specialist provider may consider funding qualifying supplier costs.
However, purchase order financing is not universally suitable for construction, engineering or project-based service contracts.
Some providers primarily finance transactions involving goods purchased from suppliers and delivered to end customers.
Businesses requiring money for in-house labour, fabrication or complex project execution should confirm whether those expenses are eligible.
A signed customer contract does not automatically establish that a purchase order facility is available.
6. Business Overdrafts
An overdraft may help an established company manage relatively short cash-flow gaps.
For example, a firm might need £15,000 for payroll while waiting two weeks for a milestone payment.
An approved overdraft can provide temporary liquidity within the facility limit.
However, interest, fees, repayment-on-demand conditions and reviews can apply.
Overdrafts may be unsuitable as the sole source of funding for a large project with substantial and prolonged expenditure.
7. Asset-Based Lending
Larger project-based businesses may have eligible assets that can support secured lending.
These might include trade receivables, inventory, machinery and other acceptable collateral.
An asset-based lending provider may assess several categories of business assets within a financing structure.
This can be relevant to manufacturers, engineering firms and established contractors with significant working capital requirements.
However, outstanding project applications and unfinished work may not be treated as equivalent to completed and collectible receivables.
The lender will determine what collateral qualifies.
8. Equipment Finance
If the project requires machinery or equipment that the business expects to use beyond the individual contract, asset finance may be appropriate.
Examples include construction machinery, fabrication equipment, material handling systems and eligible IT hardware.
Financing the productive asset separately can preserve working capital for labour and materials.
However, equipment finance is not necessarily suitable for ordinary project payroll or general operating expenses.
The business should distinguish capital investment from the temporary cash needed to perform the project.
9. Customer Deposits and Mobilisation Payments
Sometimes the most practical financing solution involves negotiating different payment terms rather than taking on additional debt.
For example, a contractor might negotiate a mobilisation payment to cover early material purchases.
A customer may agree to provide an upfront deposit, approve more frequent milestones or make certain payments when materials are ordered.
These arrangements can reduce the peak funding requirement.
However, customer deposits are subject to the contract, and any legal, accounting or security consequences must be considered.
Where the agreement involves construction operations, the relevant statutory payment framework may also affect how payment provisions should be drafted.
10. Supplier Credit and Subcontractor Payment Terms
Supplier credit may reduce how long the business has to finance materials.
For example, a supplier might offer 30-day payment terms rather than requiring the full amount before delivery.
However, the contractor must meet its legal and contractual payment obligations.
It should not assume that it can indefinitely delay paying subcontractors simply because its customer has not paid.
Negotiating legitimate supplier credit is different from withholding payments in breach of the agreed terms.
Can You Finance a Project Before the Milestone Is Completed?
Potentially, but this is where financing options become more restricted.
A lender may be willing to consider a business with a signed contract and strong historical trading performance.
However, future milestone revenue is not the same as an existing eligible invoice.
The distinction can be understood through four stages.
Stage 1: Contract Awarded but Work Not Started
A signed contract may establish a commercial opportunity and expected future payments.
However, the company may not yet have earned any of the milestone amounts.
An ordinary invoice finance provider is unlikely to treat the entire contract value as an existing receivable.
General working capital, suitable supplier finance or other specialist transaction-based funding may be more relevant.
Stage 2: Work Underway but Milestone Not Reached
The company may have incurred labour and material costs without becoming entitled to a milestone payment.
A conventional loan or revolving facility may be considered based on overall business affordability.
However, work in progress does not automatically qualify as invoice finance collateral.
Stage 3: Milestone Completed but Awaiting Approval
The business may believe it has completed the work and be entitled to payment.
However, the contract might require inspection, acceptance or certification.
Some specialist providers may consider certain applications for payment.
Others may require additional confirmation before advancing funds.
Stage 4: Milestone Approved and Validly Invoiced
A completed and accepted milestone supported by a valid invoice may be more suitable for ordinary receivables finance.
Even then, approval depends on the customer, invoice, contractual deductions and the finance provider.
For construction contracts, certification does not necessarily eliminate retention, pay-less notice or other payment risks.
The lender will examine the actual collectible amount.
Construction Milestone Payments: What UK Contractors Need to Know
Construction projects can be subject to specific statutory payment rules.
These requirements do not automatically apply to ordinary software, consulting or non-construction commercial contracts.
Housing Grants, Construction and Regeneration Act 1996
In England, Wales and Scotland, Part II of the Housing Grants, Construction and Regeneration Act 1996 establishes important payment and adjudication rights for construction contracts within its scope.
Under section 109, parties to qualifying construction contracts generally have an entitlement to instalment, stage or periodic payments, subject to provisions including the exception for contracts specified or agreed to last less than 45 days.
The parties can agree relevant payment amounts and intervals.
The statutory framework also provides requirements concerning payment due dates, notices and final dates for payment.
Official source: Housing Grants, Construction and Regeneration Act 1996, Section 109.
Payment Notices
For qualifying construction contracts, the payment framework includes requirements concerning notices stating the amount considered due and the basis for its calculation.
The terms of the contract and applicable legislation determine the relevant dates and procedures.
A contractor should maintain accurate records showing what has been applied for, notified and paid.
Pay-Less Notices
A payer may be able to issue a valid pay-less notice reducing the amount it intends to pay, subject to statutory and contractual requirements.
For example, a subcontractor may apply for £80,000 but receive a valid notice identifying a lower amount payable.
The lender may need to assess the actual amount due under the applicable payment mechanism.
The amount a contractor has applied for is not necessarily the amount that a lender will finance.
Official source: Housing Grants, Construction and Regeneration Act 1996, Section 111.
Adjudication
Qualifying construction contracts generally carry statutory rights to refer disputes to adjudication.
Adjudication can provide a relatively rapid dispute resolution mechanism in construction.
However, an adjudication dispute does not itself mean financing will be available.
A provider may be reluctant to advance funds against materially disputed receivables.
Legal advice may be appropriate when the parties disagree about notices, valuations or contractual payment rights.
Northern Ireland
Northern Ireland has its own construction payment legislation, including the Construction Contracts (Northern Ireland) Order 1997, as amended.
The framework includes payment and adjudication provisions relevant to qualifying construction contracts.
Although there are similar principles, contractors should not assume every procedural detail is identical throughout the United Kingdom.
Official source: Construction Contracts (Northern Ireland) Order 1997.
Retention Payments: Can You Borrow Against Money Being Withheld?
Some construction contracts permit a percentage of payment to be retained until specified completion or defects-related conditions are satisfied.
For example, a contractor may submit an application for £100,000 with a contractual retention of 5%.
The £5,000 retention would not necessarily be payable at the same time as the rest of the assessed amount.
A lender may exclude the retained portion from the eligible borrowing base or treat it separately.
Example: Financing a Certified Construction Payment
Suppose a contractor has a certified amount of £80,000.
Assume a 5% retention applies.
The retention equals £4,000.
The remaining amount is £76,000, assuming there are no additional deductions.
If a specialist finance provider agreed to advance an illustrative 75% of that eligible £76,000 balance:
£76,000 × 75% = £57,000.
The possible initial advance would be £57,000 before provider fees, reserves or other adjustments.
The lender would still need to assess the customer, contract and enforceability of the receivable.
The £4,000 retained amount is not automatically available for financing merely because it forms part of the original certified valuation.
Construction Retention Reform in 2026
The UK government's Commercial Payments Bill includes proposals to prohibit retention deductions under construction contracts.
However, the proposed prohibition was not in force as of 25 October 2026.
The Bill completed its House of Lords stages on 20 October 2026 and subsequently moved to the House of Commons.
The government has indicated that most measures are expected to commence in late 2027 or early 2028, subject to parliamentary approval and implementation arrangements.
Construction retention provisions have a separate commencement process.
Contractors should therefore continue reviewing retention provisions under the law and agreements currently applicable to them.
Official sources: UK Parliament — Commercial Payments Bill, 21 October 2026 and Parliamentary Answer — 19 October 2026.
Public-Sector Projects: When Must Customers Pay?
Some project-based businesses work with local authorities, government departments, NHS organisations or other public-sector customers.
Public procurement can involve specific payment requirements.
Under the Procurement Act 2023, qualifying public contracts are subject to implied payment provisions.
For most relevant contracts, the public authority must pay a valid, undisputed invoice within 30 days of receipt or by a later date when payment becomes due under the invoice, subject to the applicable statutory rules.
Related requirements can also apply to qualifying public subcontracts.
However, there are exceptions.
A public-sector project award does not mean every future milestone is payable immediately or that all invoices will be valid and undisputed.
The contractor must still satisfy the applicable payment conditions and submit appropriate documentation.
Official source: GOV.UK — Procurement Act 2023, Electronic Invoicing and Payment Guidance.
Businesses should also verify whether their contract falls within the relevant procurement framework.
Late Milestone Payments: What Can a UK Business Do?
Where a customer fails to pay an amount properly due under a commercial contract, the business should establish the reason.
Possible causes include administrative errors, incomplete documentation, disputed deliverables, insufficient customer funds or a contractual disagreement.
Confirm the Amount Is Actually Due
Check the signed agreement, completion evidence, payment notices and due dates.
The amount claimed should be distinguished from the amount legally payable.
Contact the Customer's Payment Team
A delay may be caused by a missing purchase order number, incorrect invoice information or another administrative issue.
Correcting the documentation may resolve the problem without additional borrowing.
Escalate Under the Contract
If the customer has not paid a properly due amount, the business may have contractual remedies.
For qualifying construction contracts, the statutory payment and adjudication framework may also be relevant.
Consider Statutory Late-Payment Rights
UK commercial late-payment law can provide rights to interest and compensation on qualifying overdue debts.
Under existing general rules, agreed payment periods usually fall within 30 days for public authorities and 60 days for business transactions.
Longer business-to-business periods may be agreed where fair to both parties.
However, the precise application can depend on the contract, sector and relevant statutory framework.
The Commercial Payments Bill proposes further reforms, but those proposals should not be treated as operative law before commencement.
Official source: GOV.UK — Late Commercial Payments.
Avoid Borrowing Against a Disputed Amount Without Understanding the Risk
A lender may not finance an amount that is materially disputed.
Even where a facility is offered, the business remains responsible for its own borrowing obligations under the agreed terms.
If the customer ultimately pays less than expected, the borrower may have to use other cash to repay the lender.
Construction VAT and CIS: Why the Cash Received Can Differ From the Invoice
Contractors should not always assume the amount shown on an invoice will equal the cash received into the bank account.
Certain construction transactions involve VAT reverse-charge rules, CIS deductions or both.
Construction Industry Scheme Deductions
Under the Construction Industry Scheme, qualifying contractor payments to subcontractors can be subject to deductions.
HMRC's published rates include:
- 20% for registered subcontractors paid under deduction.
- 30% for unregistered subcontractors.
- 0% where the subcontractor has appropriate gross payment status.
The deductions are not normally calculated on every element of the invoice in the same way.
For example, relevant materials and VAT are excluded from the CIS deduction calculation according to the applicable rules.
The amount withheld is generally treated as an advance payment towards relevant tax obligations.
Official source: HMRC — CIS Deductions and Subcontractor Payments.
Domestic Reverse Charge for VAT
Certain construction services supplied between VAT-registered businesses can fall within the domestic reverse-charge rules where the statutory conditions are satisfied.
Under those arrangements, the supplier does not collect VAT in the usual way for the affected supply.
Instead, the customer accounts for the VAT under the relevant rules.
The precise treatment depends on whether the work falls within CIS, the VAT status of the parties, the applicable VAT rate and any end-user or intermediary exclusions.
This can affect the cash that a contractor receives and the amounts it should include in its financing forecast.
Official source: HMRC — VAT Domestic Reverse Charge for Construction Services.
Why This Matters for Milestone Finance
A contractor should model actual expected cash receipts.
A project valuation of £100,000 does not necessarily mean the business will receive £100,000 in cleared cash immediately.
Retentions, valid deductions, VAT treatment and disputed variations may alter the amount or timing.
The financing forecast should use the expected net cash receipts after applicable deductions and contract conditions.
Which Industries Commonly Need Finance Between Milestones?
Milestone-based funding requirements extend beyond construction.
Construction Contractors
Construction businesses may receive progress payments based on completed and valued work.
They may need capital for materials, labour, equipment and subcontractors between applications and payments.
Working capital, overdrafts, specialist construction finance and eligible receivables facilities may be relevant.
Mechanical and Electrical Contractors
Mechanical and electrical contractors can incur substantial costs before installation work is certified.
Examples include purchasing switchgear, HVAC equipment, cabling, pipework and other components.
Financing availability depends on the company's cash flow and the relevant contract or assets.
Commercial Fit-Out and Interiors Firms
Office fit-out contractors may have to pay suppliers, installers and subcontractors before reaching customer acceptance milestones.
Lenders may examine project margins, staged payments and the value of any outstanding installation work.
A confirmed project does not automatically make every future milestone financeable.
Engineering and Fabrication Businesses
Engineering companies may require materials and labour to manufacture custom components or complete specialist contracts.
The payment schedule might involve deposits, manufacturing completion, factory acceptance testing and final installation.
Project financing should account for the possibility that technical acceptance takes longer than expected.
Manufacturing Companies
Manufacturers may use milestones when producing equipment or other high-value products under customer contracts.
A large order can create substantial raw-material and payroll requirements before the customer pays.
Equipment finance may help with machinery, while working capital may support production expenses.
IT and Software Implementation Firms
Technology companies may receive payments after completing implementation stages, testing, data migration or customer acceptance.
However, their principal costs may be employee salaries and subcontracted development work rather than materials.
A conventional working capital facility may therefore be more relevant than inventory-backed finance.
Unapproved software milestones may not qualify as ordinary invoice receivables.
Renewable Energy Contractors
Businesses installing commercial solar systems, electrical infrastructure or related equipment may receive payments at contract stages.
Large equipment purchases can precede customer payments.
The lender may evaluate the actual procurement costs, installation obligations and commissioning requirements.
Commercial Maintenance and Facilities Firms
Certain maintenance providers receive payments after completing defined contract stages or inspection requirements.
Temporary working capital may help where labour and materials must be paid before customer acceptance.
However, routine recurring service revenue and milestone-based project payments should be distinguished in the forecast.
Specialist Logistics and Installation Companies
Some project logistics businesses provide equipment delivery, installation or relocation services under staged payment agreements.
They may need to finance vehicles, specialist labour and subcontractors while awaiting contractual milestones.
The most suitable finance depends on the specific asset and repayment source.
How Much Can a UK Business Borrow Against a Project Contract?
There is no universal rule allowing every company to borrow a fixed percentage of a signed contract.
A contract's value is only one consideration.
The amount available may depend on:
- The company's trading and credit history.
- Existing cash flow and profitability.
- The legal status of the project contract.
- The customer or main contractor's creditworthiness.
- The value of work already completed.
- Applications, certificates and valid invoices.
- Contractual retention and deductions.
- The amount of financing already outstanding.
- Available assets and security.
- The proposed repayment source.
For example, two contractors may each hold £500,000 projects.
One may have a 30% mobilisation payment, short payment intervals and strong cash reserves.
The other may receive no initial deposit and wait 60 days after each certified stage for payment.
The funding requirements and credit risks can be substantially different despite identical headline contract values.
The appropriate loan amount is linked to the real cash gap and repayment capacity, not simply the size of the order book.
How Lenders Assess Milestone Payment Financing Applications
Project finance underwriting often requires more than ordinary annual accounts.
Trading History
Established companies may demonstrate a record of successfully completing projects and collecting milestone payments.
A newer company may have less historical evidence and could face additional requirements.
There is no single minimum trading period across all UK commercial finance products.
Customer Creditworthiness
A lender may assess whether the customer or main contractor is financially capable of making the expected payments.
A large customer name does not automatically guarantee payment.
The provider may review payment behaviour, credit risk and contractual rights.
Project Profitability
A £300,000 contract can appear attractive, but it may provide relatively little contribution after materials, subcontractors and labour.
The lender may assess whether enough cash will remain after delivery costs to service the financing.
Contract Terms
Relevant issues include the scope of work, milestone definitions, approval procedures, payment terms, variations, termination provisions and any rights of set-off.
Existing Project Commitments
A company delivering several projects simultaneously may have substantial working capital requirements.
A profitable contract should not be evaluated without considering the cash required for other active work.
Borrower Credit and Existing Debt
The lender may review bank statements, outstanding finance, credit history and relevant director guarantees.
Repeated overdrafts, missed payments or weak financial management can affect eligibility.
Security and Personal Guarantees
Some lenders may require security over eligible assets, receivables or the company more generally.
Others may require personal guarantees.
The borrower should understand how the arrangement affects other lenders and existing security interests.
Documents Needed to Apply for Finance Between Milestone Payments
Documentation requirements depend on the lender and product.
For project-related financing, useful information may include:
- The signed customer contract or subcontract and amendments.
- The project value and detailed scope of work.
- Payment milestones and due dates.
- Evidence of completed work.
- Applications for payment and relevant valuation records.
- Certificates, payment notices and pay-less notices where applicable.
- Valid invoices and customer remittance information.
- Details of retention amounts and release conditions.
- Material and subcontractor quotations.
- A cash-flow forecast showing project receipts and expenditure.
- Historical financial statements and management accounts.
- Recent business bank statements.
- Details of existing lending and security.
- Information about other active projects and customer concentration.
A lender may also request confirmation of contract variations, disputes or customer acceptance conditions.
The business should explain the status of each expected payment accurately.
Sensitive contracts and financial records should be shared only through appropriate secure channels.
How to Improve Your Chances of Getting Milestone Payment Finance
A stronger application provides a clear explanation of the financing need and repayment source.
Prepare a Project Cash-Flow Forecast
Record every major expected payment and expense against the date it is expected to occur.
Calculate the largest cumulative cash deficit.
The forecast should identify whether financing is required at the start or later during the project.
Separate Confirmed and Expected Revenue
A signed contract, certified payment, valid invoice and prospective order are not the same thing.
Lenders should be able to distinguish amounts already due from amounts dependent on future work.
Show Project Margins Clearly
Provide a breakdown of customer revenue, materials, subcontractors, labour and other direct costs.
Explain how much contribution should remain after financing costs.
Demonstrate Previous Project Performance
Where available, provide examples of completed projects with supporting payment records.
A reliable history of delivering work and collecting contractual payments can be useful in underwriting.
Identify Contractual Risks
Disclose retentions, outstanding variations, potential deductions and relevant payment disputes.
Withholding information can undermine the application and create problems after funding.
Stress-Test Payment Delays
Review what happens if a milestone payment arrives 15 or 30 days later than expected.
Also assess whether the company can meet repayments if the customer pays less than anticipated.
Avoid Over-Borrowing
Borrowing more than necessary can increase fees and interest costs.
A facility matched to the actual cash gap may be more efficient than a larger fixed loan, where suitable and available.
When Milestone Payment Finance May Be Unsuitable
Borrowing between milestones can help a viable company manage payment timing.
However, it may be inappropriate where the underlying project cannot generate sufficient contribution to repay the financing.
For example, a contractor may have accepted a project with margins too low to cover materials, labour and overheads.
A loan might allow the company to continue spending money, but it would not correct the project's underlying economics.
Other warning signs include substantial disputed work, unpaid variations that have not been agreed, repeated payment defaults by the customer and a borrowing requirement that exceeds the company's realistic repayment capacity.
A company should also be cautious where the loan matures before the relevant milestone is likely to be approved or paid.
If a bridge loan depends entirely on one uncertain receipt, the business could face serious financial pressure if that payment is delayed.
Financing can address a timing problem. It cannot guarantee that a customer will pay or make an unprofitable contract commercially viable.
Government-Backed Finance for UK Project-Based Businesses
Eligible UK companies may also investigate the Growth Guarantee Scheme.
The scheme is administered by the British Business Bank and operates through accredited commercial lenders.
It can support legitimate business purposes, including working capital and investment.
Supported products include term loans, overdrafts, invoice finance, asset finance and asset-based lending.
Under the operational terms published in October 2026, the scheme generally supports facilities of up to £2 million per business group, subject to Northern Ireland and other relevant exceptions.
The published operational turnover limit remains £45 million on a group basis.
In July 2026, the government announced an expansion that would increase turnover eligibility to £54 million and provide greater flexibility for certain longer-term facilities.
The British Business Bank has stated that the enhancements are being implemented through accredited lenders.
Applicants should verify which criteria are operational when applying.
Does the Government Guarantee the Borrower's Repayments?
No.
The scheme provides a 70% government-backed guarantee to the lender against qualifying credit losses.
The borrowing business remains responsible for the full contractual debt.
The guarantee does not remove the need to demonstrate a viable proposal or satisfy underwriting requirements.
Personal guarantees or other security may also be requested under the applicable rules.

How to Apply for Business Finance Between Project Milestones
Step 1: Confirm the Contract and Payment Schedule
Review the signed agreement.
Identify each milestone, the evidence required to trigger payment, relevant approval procedures and expected cash collection dates.
Step 2: Calculate the Project's Funding Gap
Prepare a forecast of materials, payroll, subcontractors and other expenses.
Deduct actual scheduled customer receipts.
Identify the maximum expected cumulative cash shortfall.
Step 3: Consider the Business's Existing Resources
Review cash reserves, existing credit facilities and other active project commitments.
The company may not need external financing for the entire calculated project gap if appropriate funds are already available.
Step 4: Identify the Appropriate Financing Structure
Determine whether the requirement is general working capital, a recurring revolving credit need or financing against an eligible invoice or construction payment application.
Step 5: Prepare Supporting Evidence
Gather contracts, payment schedules, financial records and documentation supporting the relevant milestone.
Disclose any retention, disputes or conditions that could affect payment.
Step 6: Compare Written Financing Offers
Review the net amount received, fees, interest calculation, repayment dates, security and early settlement terms.
For milestone-backed arrangements, establish what happens if the customer pays late or less than expected.
Step 7: Complete Underwriting
The financing provider may carry out credit, financial, identity and transaction verification.
An indicative decision is not a final approval or guarantee of funds.
Step 8: Monitor Cash Flow Throughout the Project
Update forecasts as actual costs and customer payments change.
If a milestone is delayed or a major cost increases, assess the effect on the financing arrangement promptly.
The British Business Bank's reforecasting guidance recommends updating forecasts when material events change the financial assumptions.
Frequently Asked Questions About Business Finance Between Project Milestones UK
Can I get a business loan while waiting for a milestone payment?
Potentially, yes.
Some commercial lenders may consider businesses with temporary funding gaps between customer payments.
Eligibility depends on the company's financial position, loan product and repayment capacity.
Can a construction contractor borrow against a stage payment?
Some specialist construction finance providers may consider qualifying applications for payment, certified sums or eligible invoices.
However, the provider must evaluate the contract, payment status, customer and any relevant deductions or disputes.
Can I finance a project before work is completed?
Potentially.
A conventional working capital facility or suitable purchase order finance arrangement may be available in certain circumstances.
However, ordinary invoice finance generally relies on qualifying receivables rather than unfinished future work.
Do I need a signed contract to apply for milestone financing?
A signed agreement may be important for transaction-specific financing.
However, conventional business lenders can have different eligibility requirements.
A verbal customer commitment or unsigned quotation is not equivalent to an enforceable contract.
Can I borrow against an uncertified application for payment?
Some specialist construction finance providers consider certain uncertified applications.
Others require certification or an eligible invoice.
Approval depends on the contract, valuation evidence, payer risk and other underwriting conditions.
Can I borrow against a disputed milestone payment?
Disputed amounts can be more difficult to finance.
A lender may exclude disputed balances or decline an application where the expected payment is materially uncertain.
Can I finance construction retention payments?
Certain specialist providers may consider eligible retention-related amounts.
However, retentions are often restricted or excluded until the relevant release conditions are satisfied.
A retained amount is not automatically available for immediate financing.
Can I get £50,000 between customer milestone payments?
Potentially.
A £50,000 requirement may fall within the range of various UK commercial lending products.
Approval depends on affordability, creditworthiness, product conditions and any eligible security or receivables.
Can I get £100,000 against a signed project contract?
Potentially.
However, a £100,000 contract-backed funding request does not mean the contract itself guarantees the borrowing.
The lender may assess the company's wider financial position, project costs, existing payments and actual repayment source.
Can a new construction business obtain project finance?
Some specialist lenders may consider newer companies with qualifying contracts or other acceptable support.
However, limited trading history can restrict available products.
There is no universal startup approval rule across UK commercial lenders.
Can engineering companies obtain milestone funding?
Potentially.
Engineering firms may investigate working capital loans, revolving facilities, asset finance or suitable transaction-based financing depending on the contract.
Can software companies get financing between implementation payments?
Yes, potentially.
Software implementation firms may be considered for commercial working capital facilities.
However, payments dependent on future acceptance or uncompleted work are not automatically eligible for invoice finance.
Can I use a business loan to pay subcontractors?
Some commercial working capital products permit eligible subcontractor and project delivery expenses.
However, the borrower must demonstrate affordability and comply with its contractual and statutory obligations.
What happens if the customer pays late?
The company's loan repayments generally remain due under the financing agreement.
The borrower should review whether the contract permits an extension or another arrangement.
The lender is not automatically required to wait until the customer pays.
Does the customer have to know about invoice finance?
It depends on the financing structure.
Factoring arrangements may involve customer notification or direct collections.
Certain invoice discounting arrangements may operate confidentially, subject to contractual and provider requirements.
Is project milestone finance expensive?
Costs vary considerably.
Some facilities use interest and arrangement fees.
Receivables finance may include service and discount charges.
Specialist transaction-based products may use different pricing structures.
Borrowers should compare the total cost against the amount received and repayment period.
Can customer deposits reduce borrowing needs?
Yes.
A deposit or mobilisation payment received before substantial project expenditure may reduce the peak cash requirement.
However, the payment must be contractually agreed and may have accounting, tax or other implications.
Can a company with bad credit obtain milestone financing?
Some specialist providers may consider adverse-credit applicants.
However, weak credit, unpaid debts and affordability problems can limit the available options.
A strong customer contract does not automatically override poor repayment capacity.
Does the Growth Guarantee Scheme cover project working capital?
Eligible lenders may provide supported finance for legitimate business working capital purposes.
However, the scheme has borrower, product and lender requirements.
A signed contract does not automatically qualify a company for government-backed finance.
How quickly can milestone finance be approved?
Timescales depend on the provider, borrower, contract documentation and underwriting complexity.
Some specialist providers advertise short processing periods for qualifying applications.
However, an advertised decision time is not a guaranteed funding date.
Are project milestone business loans regulated by the FCA?
Not all UK commercial lending falls within the Financial Conduct Authority's consumer credit regulatory perimeter.
The position depends on the borrower, agreement and activity.
Certain smaller business borrowing arrangements involving sole traders or qualifying partnerships may be regulated, while much lending to limited companies falls outside that perimeter.
Businesses should verify the status of the actual agreement.
Final Verdict: Which Finance Option Fits the Gap Between Your Project Payments?
Businesses working under milestone-based contracts can experience substantial cash-flow pressure even where the underlying projects are profitable.
The challenge is often the timing difference between paying project expenses and receiving the next customer payment.
For established companies with a one-time funding requirement, a conventional working capital loan may be appropriate if the repayment schedule is affordable.
For businesses managing several recurring project cash-flow gaps, a revolving credit facility may provide a more suitable structure.
For companies holding eligible unpaid invoices, receivables finance may help release cash before the customer pays.
For construction businesses with applications for payment or certified valuations, specialist construction finance may offer additional possibilities, subject to the provider's assessment.
For companies purchasing goods to fulfil confirmed orders, purchase order or trade finance may be worth investigating.
For businesses buying machinery used across multiple projects, equipment finance may help preserve operating cash.
The £180,000 worked example demonstrates why the contract's total value should not be confused with the amount that must be financed.
The project was expected to generate £24,000 in direct contribution, but its maximum cumulative cash shortfall reached £93,000 before the first significant customer milestone was paid.
A properly prepared cash-flow forecast can reveal this requirement before the business commits to substantial spending.
The most suitable milestone financing arrangement is one that covers the genuine funding gap, aligns repayments with credible cash receipts and leaves the business able to operate if a customer payment is delayed.
