If the customer doesn’t pay up, the next step is to start court proceedings against them. In England and Wales, debts of up to £10,000 are dealt with as small claims in the county court. Claims of £10,001 – £25,000 are also normally dealt with at the county court. Claims of over £25,000 are dealt with in the High Court. You need to pay a court fee to start proceedings. For more details on taking court action against customers who’ve not paid you, including information on court fees, go to the make a court claim for money section of GOV.UK.
