What is Construction Factoring?

Construction Factoring is a specialist invoice finance product, used by businesses in the Construction industry and associated trades. This product is only offered by a small pool of UK funders that understand and have an appetite for the often-complex nature of construction contracts. 

Your company may complete a stage of a contract and raise an application for payment. You can then release funding within 24 hours of raising a certified or uncertified application for payment. Typically, you can receive a higher advance if you can wait for the payment certification to be received.

With long payment terms and late payments continuing to be a challenge in the construction industry, faster access to your capital can help you with enabling costs on new projects and to meet your own ongoing financial commitments, such as materials, payroll and HMRC

Why Standard Invoice Finance Doesn’t Always Fit Construction

Most invoice finance is built around a simple idea, you deliver goods or services, you raise an invoice, and that invoice is treated as an undisputed debt. Construction rarely works quite that cleanly. You might submit an application for payment showing what you believe is due, which then needs assessing and certifying by a main contractor, quantity surveyor or contract administrator before it becomes formally agreed. Part of every payment may also be withheld as retention until practical completion, or until the end of a defects period. Main contractors can apply contra charges, issue pay less notices, or dispute variations before they agree to pay.

None of this means you can’t access funding, it simply means you need a lender who understands how to assess this kind of debt properly, which is exactly why construction factoring exists as its own specialist product within invoice finance.

What Can Be Funded

Not every type of construction debt is treated the same way by a lender. Here’s a general guide to how different types of applications and invoices are typically viewed, though this will always depend on your specific contract and lender.

What You’re Claiming For Can It Typically Be Funded? What Affects It
Certified application for payment Usually, yes The certified value, your customer’s credit standing, and any retention withheld
Uncertified application for payment Only with specialist lenders Your contract history, how often past applications have been reduced on certification, and the customer’s payment record
Completed work invoice Usually, yes Whether the invoice is undisputed
Staged or milestone invoice Often Whether the milestone has been formally accepted
Retention Usually excluded or restricted The release date and defects period
Unapproved variation Difficult until agreed Needs formal instruction and acceptance first
Materials on site Case by case Whether title has passed and the materials are identifiable and insured

How Construction Factoring Works

We start by reviewing your business, your ledger and a sample of your contracts. We identify whether you’re mainly raising invoices, applications for payment, or a mixture of both, and we look at your certification history, meaning how often your applications are certified close to the value you originally submitted. We then compare this against our panel of construction factoring funders to find those most likely to accept your specific contract structure. Once a facility is agreed, funds are typically released within 24 hours of a certified application being submitted, and in some cases an uncertified one too, with the balance reconciled once your customer pays in full.

A Worked Example

Here’s an illustrative example only, your own facility will depend on your lender, your contract and your application history.

A subcontractor submits a certified application for payment worth £100,000, with £5,000 retention withheld. Lenders offering construction factoring typically agree an advance of between 50% and 65% against certified applications like this, so an initial payment could be released within 24 hours of the application being submitted. Where an application hasn’t yet been certified, funders who accept uncertified applications typically advance a lower proportion, often in the region of 40% to 55%, reflecting the extra risk involved before the value has been formally agreed. In both cases, the remaining balance is paid once the main contractor settles the application in full.

Construction Factoring can offer additional benefits such as credit control. This allows the funder to collect outstanding invoices on your behalf, confidentially if required so they are unaware of the funder’s involvement. You can also include bad debt protection which protects your advance in the event of client insolvency or non-payment of invoices. 

If you are a main contractor or sub-contractor working in the UK construction this could be an ideal product for you. Whether you are working under a contract, framework agreement or purchase order, or if you raise an application for payment for part or completed works, we can guide you through the options available.

Summary of Benefits

Construction factoring in the UK offers several benefits tailored to the specific needs of the construction industry.

Construction Factoring provides immediate access to funds tied up in unpaid invoices, ensuring a steady cash flow. This liquidity is crucial for covering payroll, purchasing materials, and meeting other financial obligations during the project lifecycle.

Construction projects often face delays in payments due to extended project durations or complex payment structures. Construction Factoring allows construction companies to avoid cash flow interruptions caused by delayed payments, providing stability and financial security.

Construction Factoring enables construction firms to bridge the gap between invoicing and receiving payments, ensuring access to working capital for ongoing operations, subcontractor payments, and project management costs.

As construction companies take on larger projects or face seasonal fluctuations, construction factoring offers a flexible funding solution that grows with the business’s invoicing volume, supporting expansion and scalability.

Construction Factoring companies can handle the collection of invoices, reducing the administrative burden on construction firms. This allows them to focus on project execution and client relationships without spending resources on chasing payments.

Predictable cash flow through construction factoring can facilitate better financial planning, enabling construction companies to allocate resources efficiently, bid on new projects, and manage ongoing construction work more effectively.

Some construction factoring arrangements include credit protection services, safeguarding construction companies against potential losses due to customer insolvency or non-payment.

Construction Factoring provides a consistent source of cash flow, helping companies navigate through cash-intensive projects, unexpected expenses, or economic downturns with greater financial stability.

Overall, construction factoring in the UK serves as a strategic financial tool specifically designed to address the unique cash flow challenges faced by construction firms, ensuring smooth operations and sustained growth within a challenging industry.

Construction Factoring Glossary

A few of the terms you will come across when arranging construction factoring, explained simply.

Application for payment: a request a subcontractor submits to a main contractor for payment of work completed so far.

Certified application: an application for payment that the main contractor or their surveyor has checked and agreed, confirming the value that will be paid.

Uncertified application: an application for payment that has been submitted but not yet checked or agreed by the main contractor.

Retention: a percentage of the contract value withheld by the main contractor until the work is finished or an agreed defects period has passed.

Contra charge: a deduction the main contractor makes from what they owe you, often to cover costs they say resulted from your work.

Pay-less notice: a formal notice a main contractor issues to explain why they intend to pay less than the amount applied for or invoiced.

Final account: the final agreed figure for a contract once all work, variations and deductions have been settled.

Debtor concentration: how much of your total turnover comes from a single customer, which funders look at when assessing risk.

Can I Switch From My Current Construction Factoring Provider?2026-07-31T22:51:07+00:00

Yes. Businesses switch construction factoring providers for a number of reasons, including restrictive reserves, poor understanding of applications for payment, or a facility that no longer matches their turnover. We can review your current ledger and contracts and help you compare what a new facility would actually make available, not just its headline limit.

Is Construction Factoring Confidential?2026-07-31T22:51:44+00:00

Yes, in many cases. Confidential facilities mean your customers are not made aware of the funder’s involvement, and your business continues to manage its own credit control. Not every lender offers this on construction facilities, so it’s worth telling us early on if confidentiality matters to you.

Can I Get Funding If One Main Contractor Makes Up Most of My Turnover?2026-07-31T16:18:22+00:00

Concentration with one customer can make funding more challenging, but it doesn’t automatically rule it out. Lenders will look at the credit strength of that main contractor and your payment history with them. This is exactly the kind of detail we go through with you before approaching funders, so we’re not putting you in front of a lender who’s unlikely to accept your particular circumstances.

Can a Start-Up Construction Business Get Factoring?2026-07-31T16:17:55+00:00

It’s possible, though start-ups are generally assessed more closely, particularly around the strength of the contracts in place and the credit standing of the main contractors you’re working with. We can talk you through what a lender is likely to want to see and help present your business in the best possible light.

What Happens If My Application Is Certified for Less Than I Claimed?2026-07-31T16:17:28+00:00

Your funder will normally reconcile your account against the certified or paid value rather than the amount originally submitted. If this happens regularly, a lender may adjust your future availability or hold a reserve, which is why your certification history matters so much when a facility is being set up.

Can Retentions Be Financed?2026-07-31T16:17:00+00:00

Retention money is usually excluded from what can be funded, since it isn’t due to be paid until practical completion, or in some cases the end of the defects period. A small number of lenders may take a different view in specific circumstances, but it shouldn’t be assumed that retained amounts will be included in your available funding.

How Much of an Application or Invoice Can I Access?2026-07-31T16:16:34+00:00

It depends on the type of debt and the lender. Certified applications for payment typically attract an advance of around 50% to 65%, while uncertified applications, where a lender accepts them at all, are usually advanced at a lower rate, often in the region of 40% to 55%. The exact figure depends on your contract, your customer and your payment history.

What Is the Difference Between an Application for Payment and an Invoice?2026-07-31T16:16:08+00:00

An invoice is usually raised for completed, agreed work and is treated as an undisputed debt. An application for payment is a request for an amount you believe is due, which then needs to be assessed and certified by a main contractor, quantity surveyor or contract administrator before it’s formally agreed. That extra step is why construction debts are assessed differently to standard invoices.

Can Uncertified Applications for Payment Be Funded?2026-07-31T16:15:39+00:00

In some cases, yes, though only a limited number of specialist lenders will consider uncertified applications. They will typically look at your contract, your history of previous applications versus what was actually certified, and the payment record of your customer, before agreeing an advance, usually at a lower rate than a certified application would attract.

Can I Get Funding Against an Application for Payment, Not Just an Invoice?2026-07-31T22:55:13+00:00

Yes. This is one of the main differences between construction factoring and standard invoice finance. Specialist construction funders are set up to assess and fund applications for payment, including staged or milestone applications, rather than only completed invoices.

How Does Construction Factoring Work?2026-07-31T16:14:08+00:00

Once a facility is in place, you continue submitting your applications for payment or invoices as normal. Your funder then advances a percentage of the certified, or in some cases uncertified, value, often within 24 hours. The remaining balance is paid once your main contractor settles the application in full, minus the funder’s fees.
