Chasing unpaid invoices is one of the most draining parts of running a business. When a customer cannot or will not pay on the original terms, you are left weighing up whether to write the debt off, issue a court claim, or find a middle path that actually gets you paid. A debt repayment agreement often sits in that middle path. It puts the debt, the instalments and the consequences of non-payment in writing, so both sides know exactly where they stand. On this page I walk through what these agreements do, when they make commercial sense, and the sections you should expect to see. If you would rather talk through your own situation with someone before putting anything in writing, there is a call option further down.

What this document is

A debt repayment agreement is a written contract between a creditor and a debtor that restructures how an existing debt will be paid off. Rather than suing for the full sum in one go, the creditor agrees to accept the money over a period of time, usually by fixed instalments, in return for the debtor acknowledging the debt and committing to the new schedule.

For small businesses and sole traders in England and Wales, these agreements are a useful halfway house between informal chasing and formal legal action. They preserve the commercial relationship where that still matters, reduce the time and cost of recovery, and give you a cleaner route back to court if the debtor later breaks the promise.

The document does not create a new debt; it records how an existing one will be settled. That distinction matters because it keeps your original rights intact if the plan breaks down, provided the agreement is drafted to say so.

How to use this document

  1. Confirm the debt is genuine and quantified. Before you put anything to the debtor, check that the sum owed is accurate, that your invoices were properly issued, and that there is no live dispute over the goods or services. A repayment agreement only works when both sides accept the underlying amount, so iron out any disagreement on the figure first.
  2. Speak to the debtor and understand their position. Ask what they can realistically pay and when. A schedule that ignores the debtor's actual cashflow will fail within weeks. You want instalments that are tight enough to protect you but achievable enough that the debtor will stick to them, so this conversation matters more than most people expect.
  3. Draft the agreement in clear written terms. Set out the total debt, the instalment amounts, the payment dates, the payment method and what happens if an instalment is missed. Include a clause preserving your right to claim the full outstanding balance if the debtor defaults, and make sure both parties' names and addresses are correct.
  4. Get both parties to sign and date the document. A signed copy for each side, whether wet ink or a reliable electronic signature, is what turns the conversation into an enforceable record. Keep the signed version safe alongside the original invoices and any correspondence, because you may need all of it later if things go wrong.
  5. Track payments and act quickly on default. Monitor each instalment as it falls due and chase promptly if one is missed. If the debtor stops paying, your next step may be a formal demand followed by a money claim through the County Court. Having the signed agreement makes that process considerably more straightforward.

Common questions

Q Is a debt repayment agreement legally binding in the UK?
Yes, once both parties sign it and there is clear consideration, a debt repayment agreement is a binding contract under the law of England and Wales. The debtor is agreeing to pay a sum they already owe on new terms, and the creditor is agreeing to hold off on enforcement in return. If the debtor defaults, you can rely on the signed agreement if you later need to go to court.
Q Can I charge interest on the outstanding balance?
You can, but only if the agreement says so. For commercial debts between businesses, statutory interest may already apply under the Late Payment of Commercial Debts (Interest) Act 1998. For other debts, any interest must be expressly agreed and reasonable. Spell out the rate and how it is calculated in the document, because unclear interest clauses are a common source of later disputes.
Q What happens if the debtor misses an instalment?
That depends on what the agreement says. A well drafted document will include an acceleration clause, meaning the full outstanding balance becomes immediately due if an instalment is missed. Without that wording, you may only be able to claim the missed instalment itself. Either way, the signed agreement is strong evidence of the debt if you need to issue a County Court claim.
Q Do I need a solicitor to put one in place?
Not necessarily. For straightforward trade debts, many businesses prepare these agreements themselves. That said, if the sum is significant, the debtor is a company with complicated finances, or there is any risk of insolvency, it is sensible to take proper advice. A poorly drafted agreement can accidentally waive rights you wanted to keep.
Q Is this the same as an IVA or a debt management plan?
No. An Individual Voluntary Arrangement is a formal insolvency procedure supervised by a licensed insolvency practitioner. A debt management plan is an informal arrangement usually handled by a debt advice charity or commercial provider covering multiple creditors. A debt repayment agreement is a private contract between one creditor and one debtor and sits outside those formal frameworks.
Q Can I still take court action if I sign one?
You can, but usually only if the debtor breaks the agreement. By signing, you are generally agreeing to pause enforcement while the debtor keeps to the new schedule. If they default, you can then pursue the debt through the courts, and the signed agreement often makes the claim simpler because the debt itself is no longer in dispute.
Q Does the agreement affect the limitation period for the debt?
It can. Under the Limitation Act 1980, a written acknowledgment of a debt by the debtor generally restarts the six year limitation clock for simple contract debts. Because a debt repayment agreement records that acknowledgment in writing, signing one typically protects your ability to sue on the debt for a further period if things later go wrong.
