Introduction — why this matters for construction

Construction projects commonly lock large sums of working capital into staged billing cycles, certified applications for payment and retentions. Long payment cycles from main contractors or developers, disputes over variations, and the timing of interim certificates can squeeze cashflow and make it hard to pay labour, suppliers or plant hire.

Short answer: many builders and building services firms can use invoice finance (including against staged invoices and applications for payment), but approval depends on the contract and debtor profile. To find the right route — invoice factoring, invoice discounting, contract or retention funding — complete a quick enquiry and we’ll match you to lenders and brokers who specialise in construction finance.

What is invoice finance? Quick explainer

Invoice finance is a form of working capital where a specialist lender or funder advances most of the value of your invoices so you get paid sooner. Two common types:

• Factoring: the funder typically takes responsibility for collecting invoices and credit control. Debtor relationships are usually known to the funder.
• Invoice discounting (confidential): you keep control of collections; the funder provides a confidential advance against invoices.

Typical advance rates range from around 60–90% of invoice value (depending on debtor quality, retentions and concentration), with the remainder paid when the invoice is settled less fees. Funding can be arranged quickly — often within days — once documents and contracts are reviewed.

For more detail on structure options see our guide to invoice finance.

Can construction businesses use invoice finance? Key considerations

Yes — but lenders assess construction businesses differently to standard trade services. Key factors underwriters and specialist funders look at include:

• Type of client / debtor: invoices owed by large plc developers or public bodies are generally more acceptable; smaller or new private clients can be higher risk.
• Contract documentation: clear AfP paperwork, interim certificates, and payment notices that show entitlement are crucial evidence.
• Assignment clauses: whether the contract allows assignment of payments to a funder. Some public sector contracts restrict assignment but specialist lenders have workarounds.
• Retentions and defects liability: retained sums are often excluded from the immediate advance unless insured or certified.
• Concentration risk: dependence on a single large debtor or single contract can limit advance rates; specialist contract funders can help but may charge higher fees.
• Disputes and variations: disputed invoices or substantial variation claims reduce funder appetite until resolved or certified.

Many invoice finance providers have dedicated construction desks and are experienced with staged billing and AfP under JCT, NEC and other frameworks. The right partner will understand how your applications for payment are certified and where funds can be advanced against certified stages.

Staged billing, applications for payment and retentions — how lenders treat them

Construction invoicing commonly uses staged billing and applications for payment (AfP). Funders will accept these where the documentation shows a clear entitlement to payment.

How staged billing and AfP work with funders

• Interim certificates, architect/contract administrator sign-offs and approved payment notices are treated as supporting evidence of entitlement.
• Where AfP creates interim invoices to the main contractor, funders will usually advance against the certified value, not provisional claims.
• For public-sector debtors, some lenders will advance without formal assignment if the debtor’s payment procedures prevent assignment — they rely on the reliability of the public payer.

How retentions are handled

• Retentions are often excluded from the initial advance — they are held until practical completion, defects rectified, or until certified for release.
• Some specialist lenders will advance a percentage of certified retentions (at a lower advance rate or only after retention insurance is put in place).
• Retention funding, bonding or insurance may be separate products recommended by your broker to unlock these funds.

Practical documentation funders will want

• Examples of AfP and interim certificates
• Appointment/contract terms with main contractor or developer
• Payment history and any outstanding disputes or variations

If your contract includes a clause preventing assignment, tell us in your enquiry — specialist funders or brokers who understand the issue may still be able to help.

Pros and cons for construction businesses using invoice finance

Pros

• Frees working capital tied up in staged invoices and AfP so you can pay payroll and suppliers.
• Flexible funding that grows with sales or contract value.
• Invoice discounting can be confidential, preserving client relationships.
• Specialist funders can finance retentions, provide contract funding or work with bonding solutions.

Cons / things to watch

• Fees and margin — invoice finance is not free; compare costs to alternatives.
• Retentions and disputed invoices may not be advanced immediately.
• Assignment or contract clauses can complicate funding; legal review sometimes needed.
• Dependence on a single large debtor may reduce advance rates or require specialist funders.

When invoice finance is not ideal, alternatives include contract finance, bridging facilities, retention insurance or short-term business loans — we’ll help match you to the right option. Get Started — Free Eligibility Check

Case examples (anonymised)

Example A — Electrical subcontractor
A subcontractor with multiple staged invoices to main contractors used invoice discounting to bridge 4–8 week payment cycles. The discounting line advanced 85% against certified stages, enabling steady payroll and material purchases.

Example B — Main contractor with retention funding
A main contractor with several projects and significant retentions arranged a package combining advances against certified applications and a retention insurance-backed facility. This reduced working capital pressure and avoided expensive short-term loans.

Frequently asked questions

Can I use invoice finance if my client is a public body or local authority?

Yes. Public-sector debtors are often seen as lower risk and many lenders will advance against certified invoices to local authorities. Lender specifics on assignment vary, so share full details in your enquiry.

How are retentions treated?

Retentions are frequently excluded from the initial advance. Some specialist lenders provide lower advances against certified retentions, or fund them once certified or insured. We’ll match you with lenders who offer suitable retention solutions.

Will invoice finance work if my contract prevents assignment?

Possibly. Some lenders can work without assignment in certain circumstances, especially for public sector debtors. Full contract copies help lenders assess options — include these in your enquiry.

How quickly can I get funds?

Once paperwork and due diligence are complete, many invoice finance lines can be set up in days, with advances available as soon as the funder accepts the invoices and supporting documentation.

Does enquiring via UK Business Loans affect my credit score?

No — submitting an enquiry does not affect your personal or business credit score. Partner lenders or brokers may perform credit checks only if you proceed with an application.
