Adjudication vs Invoice Finance: When Each Makes Sense
Market Invoice is an independent UK invoice finance comparison site that ranks 85 active UK lenders, with a dedicated construction finance desk.
Use adjudication when the debt is genuinely disputed and you need a binding decision; use invoice finance when the debt is undisputed and you need cash now. Adjudication under the Construction Act forces a binding decision within 28 days but costs £3,000 to £25,000 and is adversarial. Invoice finance advances 70 to 90% of the Application for Payment value within 24 hours and the financier waits to be paid, but providers will not fund a disputed sum. The two are not mutually exclusive: most subcontractors finance the undisputed certified amounts to protect cash flow and adjudicate only the contested balance. If the main contractor is insolvent, neither tool recovers the money unless non-recourse bad debt protection was already in place.

Use adjudication when the debt is disputed and you need a binding decision; use invoice finance when the debt is undisputed and you need cash now. Adjudication forces a binding 28-day decision but costs money and goodwill; invoice finance advances 70 to 90% within 24 hours but will not fund a disputed sum. Most subcontractors use both.

Summary
For a UK subcontractor unpaid by a main contractor, adjudication and invoice finance solve different problems. Adjudication under the Housing Grants, Construction and Regeneration Act 1996 forces a binding decision within 28 days, costs roughly £3,000 to £25,000 (loser usually pays the adjudicator), and is adversarial, so it fits genuinely disputed sums where the relationship is already strained. Invoice finance and Application for Payment funding advance 70 to 90% of the value within 24 hours, cost a service charge (0.5% to 3%) plus a daily discount charge, and do not notify the customer on a confidential facility, so they fit undisputed sums where the need is cash flow not a legal ruling. Finance providers will not advance against a disputed portion. The common best practice is to do both: finance the undisputed certified or notified sums and adjudicate the contested balance; once an adjudicator decides in your favour, the award becomes a fundable receivable. If the main contractor is insolvent, neither tool recovers the debt unless non-recourse bad debt protection was taken out before the failure.

Side-by-side
| Factor | Adjudication | Invoice finance |
|---|---|---|
| Best for | Disputed debt, binding ruling needed | Undisputed debt, cash needed now |
| Time to cash | ~6 weeks to decision, longer to enforce | 24 hours once facility is set up |
| Cost | £3k to £25k (loser usually pays adjudicator) | 0.5% to 3% service charge + daily discount charge |
| Resolves a dispute? | Yes, binding pending final settlement | No |
| Funds a disputed sum? | N/A | No, undisputed sums only |
| Relationship impact | Adversarial, contractor is notified | Low; confidential discounting is invisible |
| Works if debtor insolvent? | Decision may be unenforceable | Only with prior non-recourse protection |
Choose adjudication when
The main contractor is genuinely disputing the valuation, variations, defects or contra-charges, and you need a binding decision to break the deadlock. Adjudication is also the right call where a pay less notice point is strong and the sum is large enough to justify the fees, or where the relationship is already broken so there is no goodwill to protect. The statutory right comes from the Construction Act and, where the contract is silent, from the Scheme for Construction Contracts. The full process is set out in adjudication for unpaid AfPs.
Choose invoice finance when
The sum is undisputed (or there is a valid notified sum with no pay less notice) and the problem is simply that you are waiting 30, 60 or 90 days to be paid. Construction-aware Application for Payment funding advances most of the value within 24 hours and the financier carries the wait. Confidential facilities do not notify the main contractor, so there is no relationship cost. This is the route when cash flow, not a legal ruling, is the actual problem.
Use both: the common best practice
Most experienced subcontractors do not treat this as either/or. They finance the undisputed certified or notified sums so the business keeps running, and adjudicate the contested balance in parallel. When the adjudicator decides in their favour, the awarded amount becomes a known, fundable receivable, so the finance facility can then advance against it too.
