Quick summary: what you can usually expect

Construction invoice finance converts certified progress invoices into immediate cash. Typical advance rates for standard certified stage invoices range from about 70%–90% of the invoice value; where retentions, disputed or uncertified claims are involved advances often drop to 50%–80% or lower. The largest single cost is the discount margin/funding charge (commonly 0.4%–3% per month), with additional set-up, admin, transaction and monitoring fees. Funders commonly hold reserves (5%–15%) for retentions, disputes or guarantees. Exact terms vary by contract, debtor credit quality and the funder’s product.

What is construction invoice finance and how does it differ from general invoice finance?

Invoice finance for construction is designed around progress claims, staged payments and contract retentions rather than simple customer invoices. It can be delivered as disclosed factoring (the debtor is notified), confidential invoice discounting (debtor unaware) or bespoke contract-backed funding that underwrites progress certification. Construction funders will typically review the contract, certifier, retention clauses, and may require joint check arrangements, on-site inspections or contract audits. Those extra checks and retention exposures mean underwriting is more detailed and advance and fee structures differ from classic non-construction invoice finance.

Typical advance rates — detailed breakdown

• Certified stage invoices (no retention): commonly 70%–90% of certified value. Strong contractors with low dispute histories often reach 80%–90%.
• Invoices with contract retentions: advances commonly 50%–80% of the invoice when a retention (typically 5%–10%) is deducted or held as a reserve until release conditions are met.
• Uncertified or disputed claims: advances can fall to 30%–60% depending on evidence, security and who the payer is.
• Contract-backed funding: where the funder accepts the client’s certifier and the contract payment profile, higher advances are possible because the funder underwrites contract risk.

Simple examples of advance logic

Example A — £100,000 certified invoice, no retention: 80% advance = £80,000 paid now; 20% = £20,000 reserved and released (less fees) when the payer pays.

Example B — £100,000 invoice with 5% retention: net claim = £95,000. Funder advances 75% of net = £71,250 advanced now; £10,000 retention held by payer; funder holds a small reserve until retention release.

Typical fee types and ranges

Construction invoice funders commonly charge several fee components. Below are the usual fee types and typical UK ranges — always confirm exact charging mechanics with a quote.

Discount margin / funding charge (the main cost)

Usually quoted as a monthly percentage of invoice value or amount advanced. Typical range: 0.4%–3.0% per month. When shown monthly, convert to a simple annual equivalent for comparison (e.g. 1.0% per month ≈ ~12% pa simple). The exact margin depends on debtor strength, facility size, product type and whether the funder takes responsibility for collections.

Facility / arrangement fee (one-off)

One-off set-up to cover underwriting and legal work. Typical: £250–£2,000 or a small percentage (0.25%–1.0%) on larger facilities.

Monthly servicing / admin fees

For ledger maintenance, reporting and (for factoring) collections. Typical: £50–£500 per month depending on volume, or charged as a percentage of turnover where volume is very high.

Transaction / invoice fees

Per-invoice processing charges often apply: £1–£50 per invoice depending on automation and scale.

Audit, site-visit and monitoring fees

Construction funders may charge for contract audits or site visits — ad-hoc charges from £150 upward or included in admin depending on the provider.

Renewal / review fee

On annual facility renewals: often 0.25%–1.0% of facility or a fixed fee.

Credit insurance, bonding or collateral costs

If credit insurance or bonds are required these premiums/fees vary widely with debtor risk and policy terms — they can materially affect total cost.

Reserves / retentions

Not a fee but a cash holdback that reduces immediate liquidity: typically 5%–15% retained against disputes or contract retentions until cleared.

Worked examples — what a realistic deal might cost

Notes: some funders charge margin on the advanced amount rather than invoice value — this changes monthly cost slightly. These are illustrative numbers; always request a tailored quote.

What affects the rate and fees you’ll be offered?

• Debtor creditworthiness and payment history (who is paying your invoices).
• Contract type and certifier (public sector or strong main contractor improves pricing).
• Level of retentions, performance bonds or guarantees.
• Company size, profitability and trading history.
• Facility size and expected invoice volume (larger volumes usually get better pricing).
• Product: disclosed factoring, confidential discounting or contract-backed funding.
• Need for bonding, insurance or extra security.

How to get better advance rates and lower fees

• Improve contract paperwork and the certification/payment process to reduce disputes and speed up payments.
• Supply clear debtor-ledgers and evidence of consistent cash collections.
• Consolidate volumes with one specialist funder to reduce per-invoice admin fees.
• Provide audited accounts and management information to reduce perceived risk.
• Use a specialist broker to negotiate multiple funders — brokers often secure better margins for construction clients.
• Negotiate admin vs margin trade-offs — sometimes a slightly higher margin but lower fixed admin produces a cheaper outcome for high-volume users.

FAQs

What is the biggest cost with construction invoice finance?

The discount margin (the funding charge) is typically the largest recurring cost. Admin, set-up and insurance add to the total but the margin drives monthly expense.

Can I fund retentions separately?

Specialist funders sometimes provide retention finance or separate facilities for retentions and bonds, usually on different terms to progress invoice funding.

Does applying through UK Business Loans cost anything?

No — our introduction service is free and no obligation. You’ll only pay the lender/broker if you accept their finance terms.

Will an enquiry affect my credit score?
