What are milestone / stage‑payment construction contracts?

Milestone or stage‑payment contracts split the contract sum into agreed stages (mobilisation, groundworks, structure, envelope, fit‑out, practical completion). Each stage is certified by a contract administrator, architect or quantity surveyor and triggers a payment from the employer (client or developer).

Typical features:

• Fixed payment schedule with defined deliverables per stage.
• Retention clauses – a % of each stage is withheld (commonly 3–5% or 5–10%) until defects liability period ends.
• Practical completion and final account adjustments.
• Certificates or interim applications confirm the work done and value payable.

These contracts are common on both public sector and private development work. For further reading on sector finance, see our industry hub on construction business loans.

Why funding is required for stage payments

Even when a contract is signed, cash is tied up across stages. Contractors frequently need cash up front for:

• Buying materials and pre‑ordering long‑lead items.
• Paying subcontractors and labour through stages.
• Plant hire, insurances and site mobilisation costs.
• Covering retention or variations that delay payments.

When certified payments are delayed, contractors can face late supplier payments, stopped works and margin erosion. Example vignette: after completing stage 2 on a £500k job, a contractor waits six weeks for certification — suppliers demand payment now, so they seek a short‑term advance on the certified stage.

How contract financing works — mechanisms explained

C1: Overview — basic flow

Contract finance works by advancing cash against a known, verifiable future payment — typically a certified stage value or raised interim invoice. Lenders advance a percentage (the advance rate) and charge interest and fees until the next payment or final account clears the balance.

Key structural points:

• Security: loans are typically secured by a company charge or fixed charge on receivables; some lenders require a debenture and director guarantees.
• Recourse vs non‑recourse: most commercial lenders operate on a recourse basis (borrower remains responsible if the client doesn’t pay).
• Repayment trigger: repayment often comes from the employer’s payment to the contractor, sometimes via assignment or a payment waterfall arranged with the employer.

C2: Product types used for stage payments

• Contract finance / contract‑backed loans: Advances against certified stage value (often 70–90% of the certified amount).
• Invoice finance: Where contractors raise invoices per stage; factor or invoice discounter advances against those invoices.
• Retention finance: Loans that release part/all of retention sums being held by the employer or main contractor, secured by a bond or guarantee.
• Construction bridging loans: Short‑term bridging while awaiting a stage payment or final payment (days to months).
• Asset and plant finance: For funding specific equipment rather than the contract itself.
• Mezzanine / development finance: For larger projects where staged funding, equity‑like terms or sub‑debt is used.

C3: Typical process & documentation

• Submit contract, payment schedule and recent certificates to the lender/broker.
• Lender verifies the certification (may contact the contract administrator or QS).
• Offer issued with advance rate, fees, security, covenants and repayment mechanics.
• Legal documentation: facility letter, debenture or charge, sometimes assignment of rights and step‑in/repayment triggers.
• Funds advanced into contractor account; lender monitors project until repayment from next stage or final account.

C4: Worked numeric example

Scenario: £1,000,000 contract with four equal milestones (25% = £250,000 each). After stage 2 is certified, the contractor needs cash now.

• Lender advance: 85% of certified value = 0.85 × £250,000 = £212,500.
• Arrangement fee: 1.5% of advance (£3,187.50) deducted or charged up front.
• Interest: say 1% per month on outstanding (£212,500 → ~£2,125 per month).
• Net cash to contractor after fee if deducted = £212,500 − £3,187.50 = £209,312.50.
• Repayment: when stage 3 is paid by employer (£250,000), lender receives that payment (assigned) and repays the advance + interest/fees; contractor receives remaining balance.

This simplifies real deals (which can include monitoring fees, legal costs and retention holdbacks), but illustrates how advance rates and costs affect cashflow.

Costs, limits & eligibility

Costs typically include:

• Interest: quoted in % per annum or % per month (commercially often 8–18% pa for specialist short‑term facilities, depending on risk).
• Arrangement fee: 0.5–3% of facility amount.
• Monitoring/inspection fees and legal fees.
• Retention fees for holding back an amount until final account.

Advance rates generally range:

• 70–90% of certified stage or invoice value for contract finance.
• 60–85% for invoice finance depending on credit quality of the payer.
• Retention finance often lower unless backed by guarantee.

Common eligibility factors:

• Who pays you: public sector or investment‑grade developer reduces risk.
• Contract certification process and certifier credibility.
• Company trading history, recent accounts and projected cashflow.
• Size of deal (we typically introduce deals from £10,000 upwards).

Risks & mitigations

Key risks:

• Non‑payment or delayed payment by the employer.
• Disputed certificates or variations leading to payment holdbacks.
• Defects discovered at completion reducing final sums.
• Borrower cashflow mis‑management or insolvency.

Mitigations:

• Use assignment of proceeds or direct payment mechanisms where possible.
• Secure retention guarantees or bonds from the employer/contractor when available.
• Choose lenders experienced in construction who accept certified stage documentation.
• Include contingency in pricing and maintain up‑to‑date QS valuations.

FAQs

Will contract finance affect my credit score?

Submitting an enquiry via UK Business Loans does not affect your credit score. Lenders or brokers may carry out credit checks later if you progress to an application.

Can I borrow against future stage payments for multiple projects?

Yes. Many lenders will take a portfolio view and advance against multiple certified stages across projects, subject to documentation and counterparty risk.

Do lenders require director guarantees?

Often they do, particularly for small contractors or when security is limited. Larger contractors with strong accounts and reputable clients may negotiate limited or no guarantees.

How quickly can I access funds?

Specialist lenders can sometimes advance within 24–72 hours of receiving verified certificates. Complex deals or those requiring legal security will take longer.

What if the employer disputes a certificate?

If a certificate is disputed, lenders will usually pause any advance until the dispute is resolved or will reduce the advance rate. This is why clear certification and documentation are critical.
