What this usually involves

Late payment is one of the most common reasons a business first instructs a solicitor. A debt recovery solicitor can pursue the debt formally, add statutory interest and compensation, and escalate to court proceedings where a customer continues to ignore reasonable requests.

  • Reviewing the contract, purchase order and invoice trail
  • Issuing a letter before action under the Pre-Action Protocol for Debt Claims
  • Issuing county court proceedings and, if needed, enforcing judgment

Common questions

How long do I have to chase an unpaid invoice?
Most contractual debts in England and Wales carry a six-year limitation period from the date the debt fell due, but recovery rates fall sharply the longer a debt is left.
Can I add interest and costs?
Commercial debts usually attract statutory interest and a fixed compensation sum under the Late Payment of Commercial Debts (Interest) Act 1998 unless your contract sets its own rate.
