How to Handle a Trade Dispute Without Going to Court
The bathroom is half tiled, the plasterer has stopped answering the phone, and there is an invoice on the side for the full amount. Or the job is finished, but the finish is not what you agreed and now there is a row about the final payment. Trade disputes are stressful precisely because your home is the building site, and the temptation is to either pay up to make it go away or fire off an angry message you can’t take back. Neither helps. Good trade dispute resolution in the UK is mostly about staying calm, keeping a paper trail, and using the steps below in order — because the vast majority of disputes settle long before anyone fills in a court form.
The short answer
Most trade disputes are resolved by, in order: talking it through in writing, sending a clear formal complaint that states what you want, then using free alternative dispute resolution (ADR) if the trade belongs to a scheme. Court is the last resort, not the first move, and you can hold that option in reserve while you work through the earlier stages. Your legal footing is stronger than most people realise: under the Consumer Rights Act 2015, any service you pay for must be carried out with “reasonable care and skill”, and if it isn’t, you are entitled to have it put right.
The single biggest mistake is going quiet and then exploding. A dispute you handle in short, factual, written stages is one you can settle sensibly. One you handle by shouting down the phone and refusing all contact is one that drifts towards a courtroom neither of you wants.
Step one: pause, and get it all in writing
Before you decide who is right, get the facts into one place. Dig out the original quote or contract, every message, the invoices, and any variations you agreed along the way (“while you’re here, can you also…”). Then write down, calmly and in date order, what was agreed and what actually happened.
The reason this matters is evidence. A tradesperson relying on a vague verbal agreement is on weak ground against a homeowner who can produce a written quote, a message thread and dated photos of the work. Photograph anything defective or unfinished today, even if you think the job might still be rescued — you cannot go back and photograph a problem after it has been covered up or corrected. If you have kept all of this in one place rather than scattered across your phone, email and a drawer, this stage takes ten minutes instead of an afternoon.
Step two: raise it directly, in writing
Ninety per cent of the time the fastest route is a direct, unemotional message to the trade explaining the problem and what you’d like them to do about it. Not an accusation — a request. Something like: “The tiling in the bathroom has uneven grout lines and three cracked tiles, shown in the attached photos. Please can we agree a date for you to put this right?”
Keep it in writing (email or message, not a phone call) so there is a record, and give a reasonable deadline. Many disputes are simply the result of a trade juggling too many jobs, and a clear written nudge is enough to get them back. Resist the urge to withhold the entire final payment as an opening move — that can put you in breach of contract yourself. Withholding a proportionate amount that reflects the cost of putting the defect right is more defensible.
Step three: the formal complaint letter
If a friendly nudge doesn’t work, escalate to a formal written complaint. This is a specific document, and its job is to be the thing you could later hand to an ombudsman or a judge without embarrassment. It should state, plainly: what you agreed, what went wrong, which term of the Consumer Rights Act 2015 you believe has been breached (usually “reasonable care and skill”), exactly what you want them to do (repair, redo, or a refund of a stated amount), and a firm deadline — 14 days is standard.
Citizens Advice publishes free template letters for exactly this, and using their wording signals that you know your rights and you are being methodical. Send it by email and, for anything substantial, by post as well so you can prove it arrived. Keep the tone factual. The letter that wins is boring, dated and specific; the letter that loses is furious and vague.
Here is the blunt opinion: never pay the full balance on a disputed job just to keep the peace. Once the money has left your account, your leverage is gone and you are the one chasing a refund rather than withholding a payment — a far weaker position. Hold a fair, proportionate sum back, document why, and keep talking. Paying in full to avoid an awkward conversation is the most expensive mistake homeowners make in these situations.
Step four: alternative dispute resolution (ADR)
If the trade won’t engage, check whether they belong to a trade body, warranty scheme or accreditation with a dispute service. TrustMark-registered businesses, and members of bodies like the relevant competent-person schemes, are often required to offer access to alternative dispute resolution — a free or low-cost independent process that reaches a decision without a courtroom.
ADR covers mediation (an independent third party helps you reach agreement) and adjudication or arbitration (an independent decision you may both be bound by). It is faster and cheaper than court, and for many homeowners it is the stage where a stubborn dispute finally breaks. Ask the trade directly, in writing, which ADR scheme they are signed up to; if they claimed membership of a trade association when you hired them, that association is the first place to look.
Step five: when court is genuinely the last resort
If everything above fails and the sum justifies it, the small claims track of the County Court handles most consumer-versus-trade disputes in England and Wales up to £10,000 (verify the current threshold before you rely on it, and note Scotland and Northern Ireland have their own systems). It is designed to be used without a solicitor. But treat it as the nuclear option: it takes months, the fees and your time add up, and winning a judgment is not the same as collecting the money.
Before you file, you’ll normally be expected to have tried to resolve things first — which is exactly why the earlier steps matter. A tidy paper trail showing you were reasonable at every stage is the strongest hand you can hold if it ever does reach a judge.
What to do in the next 30 minutes
• Gather the quote, contract, invoices and every message into one folder or logbook, in date order.
• Photograph every defect or unfinished area now, with today’s date, before anything changes.
• Write one short, factual message to the trade describing the problem and what you want them to do, with a reasonable deadline.
• Note down which trade body, warranty or accreditation they claimed to hold — that’s your route to free ADR later.
• Decide, and write down, the proportionate amount you’re withholding and why — don’t withhold everything by reflex.
Keep the whole story in one place
The homeowners who resolve disputes quickest are the ones who can lay their hands on the contract, the quotes, the messages and the photos in one go — because a dispute is really an argument about who can evidence what. Home+ lets you store every quote, invoice, contract and job photo for each project in one place, so if a job goes wrong you’re building your case from the first day, not scrambling to reconstruct it. And if you hired through Trade Pilot, our dispute mediation gives you an independent, on-platform route to raise the issue and work towards a fair outcome without it becoming a court matter.
Frequently asked questions
What are my legal rights if a tradesperson does a bad job in the UK?
Under the Consumer Rights Act 2015, any service must be carried out with reasonable care and skill, within a reasonable time, and for a reasonable price if none was agreed. If the work falls short, you’re entitled to have it put right, and if that isn’t possible, to a price reduction. This applies to most work done for you as a consumer by a business.
Can I refuse to pay a builder for bad work?
You can withhold payment that reflects the cost of putting defective work right, but refusing to pay the whole bill when only part of the job is disputed can put you in breach of contract. The safer approach is to withhold a proportionate, documented amount and set out your reasons in writing while you try to resolve it.
What is ADR and is it free?
Alternative dispute resolution (ADR) is a way of settling a dispute using an independent third party instead of a court — through mediation, arbitration or adjudication. Many schemes are free or low-cost to the homeowner, especially where the trade belongs to a trade body or accreditation that requires it. It is usually much faster than going to court.
How much does it cost to take a tradesperson to small claims court?
There’s a court fee to start a claim, which scales with the amount you’re claiming, plus your own time. The small claims track is designed to be used without a solicitor to keep costs down. Because fees, time and the effort of enforcing a judgment all add up, it’s worth exhausting the free and low-cost steps first.
How long do I have to make a claim about faulty building work?
Time limits apply and can run to several years from when the work was done or when you discovered the problem, depending on the circumstances and whether the contract was in writing. Don’t sit on a serious defect — raise it in writing as soon as you spot it, and take advice on the deadline that applies to your situation.
