Yes, some UK specialist funders will advance against construction applications, but usually not against the full amount submitted. The usable figure normally moves from the application to the amount certified or otherwise acknowledged, less retention, set-off, contras, disputed variations and other deductions. Uncertified applications can sometimes be considered, but they attract more reserve and depend heavily on contract wording, payer quality and payment history.
The application is a claim, not yet a clean invoice
A subcontractor may have completed the work, submitted an application and recorded the whole value as revenue. A lender still has to answer a narrower question: what amount could it collect from the payer, and when, if the subcontractor could not collect it itself?
That distinction matters because a construction application starts a contractual valuation and payment process. The payer or its contract administrator may certify less than the sum applied for, issue a payment notice, or serve a pay less notice. Retention may then be deducted from the accepted value. Agreed contras, set-off rights, defects, delay claims and the treatment of variations can reduce it again.
The legal payment framework helps establish when a sum becomes due, but it does not make every figure on an application eligible for finance. Part II of the Housing Grants, Construction and Regeneration Act 1996 provides for payment notices, payment of the notified sum and adjudication. The contract, payment cycle and notices still determine the collectible amount in a particular case. This guide is about funding eligibility, not legal advice on whether a notice is valid.
Where value turns into a fundable receivable
The collateral is normally the recognised receivable, not the work in progress or the headline application value.
| Stage | Document or evidence | What sits in the ledger | Likely funding position | Repayment source | |---|---|---|---|---| | Work completed | Site records, timesheets, delivery tickets, progress evidence | Work in progress, with no application yet | Normally not invoice-finance collateral | A future application, once accepted and paid | | Application submitted | Application for payment and valuation breakdown | Amount claimed by the subcontractor | Some specialists may consider it, usually with a larger reserve and close review of past certification | Proceeds of the later certified or notified sum | | Valuation or payment notice issued | Certificate, valuation, payment notice or accepted self-bill | Amount acknowledged by the payer, subject to valid later deductions | Stronger starting point, less retention and other ineligible amounts | Payment by the main contractor, employer or other payer | | Pay less notice, contra or set-off identified | Notice and supporting calculation | Reduced or disputed receivable | Only the net, undisputed balance may remain eligible | Collection of that net balance | | Invoice or self-billed invoice raised | Invoice, authenticated receipt or self-bill matching the accepted value | Trade debt with a due date | Usually the cleanest stage, provided assignment, verification and credit tests are met | Payment into the lender-controlled account | | Retention held | Retention ledger and contractual release conditions | Long-dated contingent balance | Commonly excluded or separately reserved until release is due and undisputed | Payment at the contractual release point |
The final column is important. Construction application finance is self-liquidating only if the payer's cash clears the funded balance. It is not a permanent loan against the subcontractor's turnover.
What lenders will fund, reserve or decline
No matrix can bind a lender: appetite, facility wording and the payer's credit position vary. This is a practical screening guide for a UK limited company preparing a case.
| Item | More likely to fund | More likely to reserve or reduce | More likely to decline | |---|---|---|---| | Certified application or payment notice | The acknowledged amount with an established due date and no live dispute | Amount subject to possible later adjustment or weak supporting records | A certificate that has been withdrawn, superseded or credibly challenged | | Uncertified application | Repeated work under a signed contract where prior applications have been certified close to the amount claimed | The difference between the application and the lender's view of likely certification | Speculative claims, work outside contractual authority or no reliable certification history | | Variations | Written instruction, agreed valuation and inclusion in the certificate | Instructed but not yet valued variation, with evidence that the payer accepts the work | Oral, disputed or retrospective variation with no contractual support | | Retention | A due, invoiced and undisputed release may be considered as ordinary debt | Retention not yet due, or subject to defects and completion conditions | Remote, disputed or upstream-dependent retention with no clear release route | | Contra-charges and set-off | Net balance after a known, agreed deduction | An allowance based on the historical pattern where deductions are still being quantified | Pervasive cross-contract set-off, major defects or claims capable of wiping out the debt | | Self-billing | A self-bill issued under a valid agreement and reconciled to the application and remittance process | Value accepted in principle but awaiting the payer's self-bill | A supplier invoice raised where the agreement says only the customer may self-bill, or records that do not reconcile | | Final account | Agreed final account with a clear invoice and due date | Negotiated items not yet signed off | A claim dominated by unresolved loss-and-expense, delay or defect arguments | | Letter of intent | Work clearly within the letter's scope, date and financial cap, evidenced and accepted | Work nearing the cap or awaiting the full contract | Work beyond the cap, after expiry or outside the authorised scope | | Aged debt | Undisputed debt still within the facility's permitted ageing and payer credit limit | Older debt approaching the cut-off, pending evidence of promised payment | Debt beyond the permitted age, in adjudication or subject to insolvency concerns |
Two patterns cause more trouble than a single deduction. The first is dilution: repeated markdowns, credit notes, contras or short payments mean the ledger consistently converts into less cash than it reports. The second is concentration: one main contractor or one project accounts for most of the available debt. A lender may impose a credit limit or concentration reserve even when every application is certified.
Self-billing needs its own reconciliation. HMRC's self-billing guidance, last updated 31 December 2020, says the customer prepares the supplier's invoice under an agreed arrangement and the supplier agrees not to issue VAT invoices for the covered transactions. A finance proposal should therefore show how the application, valuation, self-bill, VAT or domestic reverse-charge treatment, remittance and ledger entry join together. Duplicating the self-bill with a supplier invoice does not create a second debt.
Worked example: from £120,000 applied to £70,350 available
This example is illustrative only. It is not a quote, an expected advance or a description of a Bedrock client. The assumed percentage is included only to show the calculation; a lender would set its own eligibility rules, reserves, fees and advance.
Assumptions
- The borrower is a UK limited-company groundworks subcontractor.
- The subcontract is signed and permits the proposed funding structure, subject to the lender completing its legal review.
- The application is for £120,000 excluding VAT. VAT is left out so the example focuses on contract deductions.
- The payer issues a valuation or payment notice for £110,000 excluding VAT.
- The contract deducts 5% retention from the certified value, equal to £5,500.
- A documented site-services contra of £4,000 is accepted by both parties.
- There are no further pay less notices, disputes, credit notes, CIS deductions or cross-contract set-offs in this illustration.
- The payer is within the lender's credit limit, and the remaining debt meets the lender's age and verification tests.
- The assumed illustrative advance is 70% of eligible debt. This is a calculation assumption, not a statement of a typical market advance.
- Fees, discount charges and any minimum service charge are excluded from the arithmetic and would reduce net cash or be charged separately under the facility terms.
| Calculation | Amount | Treatment | |---|---:|---| | Application submitted | £120,000 | Starting claim only | | Less certification markdown | (£10,000) | Not recognised as debt in this example | | Certified value | £110,000 | Starting point for eligibility | | Less 5% retention | (£5,500) | Reserved until contractually due and acceptable to the lender | | Less agreed contra | (£4,000) | Deducted from the receivable | | Eligible debt before lender advance | £100,500 | Subject to all other facility tests | | Illustrative advance at 70% | £70,350 | Initial availability before fees | | Lender reserve against eligible debt | £30,150 | Released when the payer pays, less charges and any other adjustments |
The gap between £120,000 applied and £70,350 initially available is not one large finance charge. It contains £10,000 that was not certified, £5,500 of contractual retention, £4,000 of contra and a £30,150 lender reserve. Treating all four as “the lender's haircut” hides the real issue. Better contract records may help with certification and contras; they cannot make a retention release early or remove the lender's agreed reserve.
Run this calculation across every live project, not just the cleanest application. A facility sized from one unusually strong certificate can fail when the next valuation contains larger variations or deductions.
Documents that let a lender test the real amount
A generic invoice-finance pack is not enough. For construction applications, prepare evidence that follows each amount from contract to cash:
- The signed main contract or subcontract, schedules, amendments and any live letter of intent, including its expiry date and cap.
- The payment schedule, application procedure, notice dates, final date for payment and clauses dealing with assignment, set-off, contras, retention, variations and termination.
- A project-by-project application ledger showing amount applied, amount certified or notified, invoice or self-bill, amount paid, payment date, retention and every deduction.
- The latest 6 to 12 months of applications, valuations, payment notices, pay less notices, certificates, invoices or self-bills and matching remittance advice. Use the available history; do not delay a new business solely to manufacture 12 months of records.
- Evidence for variations: written instructions, quotations, measured work, agreed rates, emails and the certificate in which each item was accepted.
- A separate retention ledger showing the original contract, amount held, practical-completion status, defects period and expected release dates. Do not bury retention inside ordinary aged debt.
- Details of disputes, adjudications, defects, delay claims, liquidated damages, warranties and known or proposed contras, including cases on another contract with the same payer.
- An aged-debtor ledger that identifies the legal payer, project, due date and concentration by payer, plus historical credit notes and bad debts.
- Latest statutory accounts, up-to-date management accounts, business bank statements and a short cashflow forecast showing how much headroom is required through the next payment cycles.
- Existing borrowing, debentures, invoice-finance arrangements and asset charges, so priority and consent issues are visible at the start.
- Where relevant, the CIS payment status and statements, VAT position and domestic reverse-charge treatment used in the ledger.
The most useful schedule is often a simple bridge from applied → certified → invoiced or self-billed → paid for each payer. It exposes the historical markdown and payment delay that an underwriter would otherwise have to reconstruct from hundreds of documents.
Construction application finance or a cashflow loan?
The credible alternative is a cashflow loan. It is repaid in agreed instalments from the business's overall cash generation rather than liquidating against named construction receivables. That makes it potentially better for a pre-certification gap, but it also means the business must service the debt even if a valuation is cut or a payer is late.
| Decision point | Construction application finance | Cashflow loan | |---|---|---| | Best fit | Regular applications that convert predictably into certified, undisputed payments | A defined shortfall before certification, or a ledger too irregular to support a revolving facility | | Amount available | Moves with eligible applications and payer credit limits | Fixed at completion and based on affordability and credit assessment | | Main repayment source | Collection of the funded receivables | Trading cashflow across the business | | Administration | Ongoing submissions, verification, reconciliations and reserves | Usually fixed repayments with less ledger reporting | | Main weakness | Availability falls when certification, concentration or disputes worsen | Repayments continue when project cash is delayed | | Exit | Collect the ledger, repay the facility and satisfy notice or minimum-term provisions | Repay over term or refinance, subject to settlement terms |
Bedrock would recommend exploring the cashflow-loan alternative where most of the funding need arises before an application becomes certifiable, the application book is small or highly irregular, or repeated disputes make receivable availability unreliable, provided the company can demonstrate affordable repayments under a downside cashflow. We would not use a fixed-repayment loan to disguise a contract that is losing money or a dispute with no credible recovery date.
If the cash is tied up in unencumbered excavators, vehicles or other plant rather than the ledger, asset refinance may match the need better. If a larger company has usable debtors plus plant, stock or property, asset-based lending may combine those assets instead of asking one uncertain application book to carry the whole facility. The wider construction finance guide explains why specialist underwriting differs from ordinary factoring; the retention cashflow guide deals with the long-dated balance that application finance often excludes.
Risks to settle before signing
Security and control of collections
The lender may require an assignment of receivables, a debenture over the company, a charge over book debts and control of the collection account. The contract may restrict assignment, require consent or allow the payer broad set-off rights. Those points need legal review before the borrower assumes the facility can fund a particular contract. Confidentiality does not remove the lender's need to verify debt or establish control.
Personal guarantees
A personal guarantee may be requested, especially where the borrower is smaller, recently established or has weak balance-sheet support. Its scope, cap and release conditions matter. A guarantee supports the lender's recourse to the guarantor; it does not turn disputed work into eligible debt. Directors should take independent legal advice before signing one.
Recourse and bad-debt risk
Most facilities provide recourse if the payer does not settle within the agreed period or if the debt becomes disputed or otherwise ineligible. The company may have to repay an advance from other cash. Bad-debt protection, where offered, has limits and exclusions; it should not be assumed to cover contractual disputes, defects, unapproved variations or dilution.
Payer and project concentration
A strong main contractor can still be too large a share of the ledger. Credit limits can change, and a reserve against the dominant payer can remove availability just when a large payroll or supplier run is due. Model the facility with the largest payer partly or wholly unavailable, not only at the headline limit.
Valuation, disputes and cross-contract set-off
Certification is a commercial valuation, not a lender valuation of an asset with a stable resale market. Under-certification, defects, delay, loss-and-expense claims and disallowed variations can move the debt after work has been completed. A right to set off a claim on Project A against money due on Project B can contaminate apparently clean invoices. Disclose the whole payer relationship, not only the funded project.
Costs and broker economics
Compare the total pounds payable, not one quoted margin. Costs may include a service or administration fee, discount or interest on drawn funds, legal and audit costs, verification charges, minimum fees, bad-debt-protection costs and termination charges. Brokers are generally paid commission by a lender when a facility completes. Bedrock explains its approach and published ranges on regulation, fees and data; the lender's offer and facility documents should show the deal-specific economics.
Exit and retained tail
An application facility can shrink faster than the company's need for cash if projects finish and new applications stop. Retentions may remain outstanding long after ordinary debt has collected, but the lender may exclude them from the run-off balance. Before signing, map the notice period, minimum term, collection of existing debts, treatment of reserves, release of security and any early-termination cost. An exit funded only by future retentions is fragile.
Payment data is useful, but it does not decide eligibility
The Department for Business and Trade's official statistics, published 14 July 2026, report that large construction businesses took an average of 33 days to pay suppliers in 2025; 14% of construction invoices by number and 13% by value were late. These are sector-level medians based on self-reported large-business data, not a forecast for a particular payer. The practical use is to test a payer's own disclosed history and the subcontractor's remittances against the wider picture, not to assume a 33-day collection date. See the 2025 payment-practices commentary.
Since financial years beginning on or after 1 April 2025, large businesses in scope that use qualifying construction contracts have had additional reporting obligations covering retention practices and performance. The Department's reporting guidance, updated 2 September 2025, explains the scope. That data can support payer due diligence, but it does not replace the borrower's own contract and payment history.
Retention reform should not be put into today's borrowing base. The government's late-payments consultation, updated 24 July 2026, considered either prohibiting retention clauses or requiring protection of retained sums. These are proposals for future legislation and transition, not a current release of existing retentions.
What to send for a first view
Bedrock works with limited companies. For an initial assessment, send one recent application, the matching contract payment terms, the latest certificate or payment notice, details of retention and contras, and a debtor ageing showing how much sits with each payer. We can then tell you whether the case looks more like application finance, ordinary invoice finance, asset-backed funding or a cashflow loan before a full lender submission.
Request indicative terms when you have those five items. For the broader funding routes available to contractors and subcontractors, use the construction sector hub.
