How to Collect Unpaid Client Invoices in the UK (Without Losing Your Sanity)
Chasing overdue invoices is one of the most frustrating parts of running a business. Fortunately, UK commercial law heavily favours creditors. Here is the step-by-step statutory process to get paid fast.

1. Your Legal Rights Under the 1998 Late Payment Act
Under the Late Payment of Commercial Debts (Interest) Act 1998, UK law gives every business the statutory right to claim:
- Statutory Interest: 8.0% per annum plus the current Bank of England base rate, calculated on a daily basis from the due date.
- Fixed Debt Recovery Compensation: Automatic statutory fees added directly to the principal balance:
- Debts up to £999.99: £40 compensation
- Debts between £1,000 and £9,999.99: £70 compensation
- Debts £10,000 and above: £100 compensation
2. The 3-Stage Escalation Protocol
Assume good faith. Most delays are administrative errors or missed inbox notifications. Re-attach the original invoice and bank details.
State the exact number of days overdue. Reference your payment terms and advise that work on ongoing retainers or deliverable releases will pause until cleared funds arrive.
Cite the 1998 Act. Add accrued statutory interest and statutory debt compensation. Give a strict 7-day deadline before filing with HM Courts & Tribunals Small Claims Service.
3. Prevention: The Contract Clause That Stops Non-Payment
The easiest invoice to collect is the one backed by a signed Master Services Agreement. Always include a Retention of Title & IP Transfer clause:
"All intellectual property rights, copyright, and source code generated for the Client remain the exclusive property of Provider until all invoices associated with the deliverables are settled in full."
