How to handle disputes with customers in the UK

Customer disputes can be a real headache for UK tradespeople. In 2026, the FSB reported that late payments and disputes cost small businesses £22.5 billion annually. If you're a plumber in Manchester owed £3,000 or a builder in Bristol facing a £1,500 payment delay, knowing how to handle disputes is important for your cash flow.

Understand your legal rights

Before diving into the nitty-gritty of dispute resolution, understand your legal rights. The Late Payment of Commercial Debts Act 1998 allows you to charge interest on late payments. As of 2026, the statutory interest rate is 8% plus the Bank of England base rate, currently at 3.5%. Use our late payment interest calculator to compute what you're owed.

Communicate effectively

Clear communication can often prevent disputes from escalating. Here are steps to consider:

• Document everything: Keep a record of all communications, agreements, and changes to work scope.
• Set clear expectations: Use a detailed contract or quote, which you can generate with our quote generator.
• Follow up regularly: Touch base with clients to ensure they're satisfied with the progress.

Negotiate a resolution

If a dispute arises, try negotiating a resolution directly. Be honest about your costs and the impact of the delay. Often, customers are unaware of the financial strain a delayed payment can cause. Here’s a simple negotiation strategy:

1. Identify the core issue.
2. Propose a fair solution.
3. Be open to compromise, if necessary.

Use mediation services

When direct negotiation fails, consider mediation. Organisations like ACAS offer free and impartial mediation services. This step can save time and money compared to going to court.

Consider legal action as a last resort

If mediation doesn’t work, you might need to pursue legal action. Before doing so, weigh the costs and potential outcomes. Small claims court can handle disputes up to £10,000. Check GOV.UK for guidance on making a court claim.

Implement preventive measures

To prevent future disputes, consider these measures:

• Use clear contracts: Specify payment terms, deadlines, and what constitutes a breach.
• Request deposits: A 20-30% upfront payment can protect against non-payment.
• Maintain a paper trail: Consistent documentation is invaluable if disputes arise.
