Construction Debt Recovery for UK Businesses

Recover unpaid construction invoices, stage payments, retentions and subcontractor debts with a practical approach built around your documents, the payment history and the debtor’s position.

Sector-specific assessment

Construction debts are rarely just “an unpaid invoice”

Payment may depend on an application, valuation, certificate, milestone, variation or retention clause. The debtor may also raise deductions, defects or set-off after payment falls due.

We first work out what is due, why it is due and what evidence supports it. That helps us separate a genuine dispute from simple delay or avoidance.

Construction payment problems

Common construction debts we can assess

We review the documents behind the balance before deciding how the debt should be pursued.

Unpaid construction invoices

Completed work, labour, materials or services that remain unpaid after the agreed due date.

02

Interim and stage payments

Applications or milestone payments delayed despite work having progressed.

Retention money

Retention sums that should have been released after completion or the defects period.

Final-account balances

Agreed or largely agreed final balances that remain outstanding.

Variations and additional works

Authorised extra work supported by instructions, emails, site records or acceptance.

Our construction recovery process

A clear five-step recovery process

We keep the process focused: identify the debt, test the dispute, contact the debtor and escalate only where justified.

Step 1

Confirm the debtor

Check the correct company, trading entity and contact details.

Step 2

Confirm what is due

Review the contract, invoices, applications and payment terms.

Step 3

Check the dispute

Assess deductions, defects, valuation issues and counterclaims.

Step 4

Pursue payment

Use focused telephone and written recovery action.

Step 5

Escalate carefully

Consider formal demand, court or enforcement only where appropriate.

Selecting the route

Choose the right recovery route

The best route depends on the evidence, dispute status, debtor’s solvency and value of the debt.

Where judgment is needed

County Court claim

Court action may be considered where the debt remains unpaid and the claim is proportionate.

Disputed construction debts

When the debtor says the invoice is disputed

Some debtors raise vague complaints only after being chased. Others have a genuine issue over value, defects, scope or completion.

We identify what is actually disputed, whether it is supported and whether any part of the balance remains clearly due.

Defects raised after chasing We check when the issue was first raised and what evidence supports it.
Valuation disagreement We compare the claimed amount, certified sums and deductions.
Missing purchase order We consider instructions, delivery, acceptance and the course of dealing.
Pay-less or deduction notice We record the notice, timing, amount and contractual basis.
“Pay when paid” explanation We distinguish cash-flow excuses from the actual payment obligation.
Counterclaim exceeds the invoice We assess whether the counterclaim is clear, evidenced and credible.
Interest and recovery costs

Can interest and compensation be added?

Depending on the contract and circumstances, you may be entitled to contractual interest or statutory interest and fixed compensation.

We check the payment terms and due dates before including additional sums in a demand.
