Your Rights When a Tradesperson Does Poor Work in the UK

By UKListingz Editorial Team Published 6 November 2026 Updated 6 November 2026 13 min read

If a tradesperson does bad workmanship in the UK, your main protection comes from the Consumer Rights Act 2015. Services must be carried out with reasonable care and skill. If they are not, you can ask the trader to put the work right, or ask for a price reduction if repeat work is not possible or they fail to fix the problem.

Key takeaways

• The Consumer Rights Act 2015 treats reasonable care and skill as a requirement of every service you buy from a trader, whether or not it is written into the contract.
• Repeat performance is usually the first remedy: you ask the trader to redo the faulty work properly, at no extra cost to you.
• If repeat work is not possible or does not fix the fault, you can ask for a price reduction that reflects the faulty work.
• Evidence decides most disputes, so photograph faults as soon as you spot them and keep quotes, invoices and messages.
• Write a clear, factual complaint, give a reasonable deadline, and only then move to a complaint body, your card provider or a court.
• Rules differ between England, Wales, Scotland and Northern Ireland, mainly in court procedure, so check the route that applies where you live.

What counts as bad workmanship under UK law?

Poor workmanship is work that falls short of reasonable care and skill. The law does not expect a perfect finish, and a small cosmetic imperfection may not be enough to justify a remedy. The real question is whether a competent tradesperson doing the same job would have done it differently.

Some faults are easy to recognise. A tiled floor that lifts within weeks, a circuit that trips under normal use, a roof that lets water in during light rain, or a wall that cracks because the surface was never properly prepared all point to a problem with the work itself. Other faults take longer to show. A joint that was not sealed properly may hold for a while before it leaks, and an electrical connection that was not tightened can cause heat problems long after the invoice has been paid.

It helps to separate the fault from the symptom. A patchy paint finish might be caused by poor preparation, and a slow drain might be caused by a pipe fitted at the wrong angle. Ask the trader to explain what they think went wrong, in writing if possible. If they cannot give a clear explanation, that is useful information in itself.

What are your remedies when the work is wrong?

For most services, the two remedies people use first are repeat performance and a price reduction. Compensation for losses that the faulty work caused may also be possible in some cases. The table below sets out the usual order and what to ask for. The exact position depends on the facts, so check GOV.UK for the current rules.

Repeat performance comes first in most cases because it gives the trader the chance to correct their own mistake. You should allow a reasonable time for the work to be redone, and you should not refuse access without a good reason, because a refusal can weaken your position later. The repeat work should be carried out without significant inconvenience to you.

A price reduction is the fallback where the trader cannot or will not fix the work, or where the repeat work fails. It should reflect the value of the work you did not get. Base the figure on the quote, the specification and the cost of having another tradesperson complete the job, and get a written second quote so you can show how you reached the amount.

Can you claim the cost of a second tradesperson?

In some cases, yes. If the poor work has caused a financial loss, such as the cost of a second contractor to fix the job, you may be able to claim that loss as compensation. Keep every invoice, quote and receipt. The claim is strongest when the loss is clearly caused by the original fault and when you gave the trader a fair opportunity to put it right first. Citizens Advice can help you judge whether a claim is realistic.

How do you prove the work is poor?

Most disputes about bad workmanship come down to evidence. Collect it while the fault is still visible, and do not wait for the trader to visit before you record what you can see.

• Dated photographs and short videos of the fault from several angles, with an object of known size, such as a tape measure, in shot.
• The written quote, contract, specification, drawings and any terms that were agreed.
• Invoices, receipts and a record of each payment, including which stage of the work it covered.
• Messages, emails and texts with the trader, saved with their dates visible.
• Notes of phone calls and visits, written up the same day, with the date, the time and what was said.
• An independent report from another qualified tradesperson that describes the fault, the likely cause and the cost of putting it right.

An independent report is not a legal judgement, but it is one of the most persuasive documents you can hold. Choose someone with the right qualification for the job, such as a Gas Safe registered engineer for gas work. Tell them that you may need the report for a dispute, and record exactly what they did if they removed parts or carried out tests.

What steps should you take first when work goes wrong?

Give the trader a fair chance to put things right, in writing, before you escalate. Most problems are settled at this stage when the request is clear and reasonable.

1. Pause any further payments until you have clarified what is in dispute, but keep paying any part you agree is fine, so you are not in breach of your own agreement.
2. Collect your evidence while the fault is still visible, following the checklist above.
3. Write to the trader, describing the fault, when you first noticed it, what the quote said and what you want them to do.
4. Set a reasonable deadline for a reply and for the repeat work to start, and write the date into the letter.
5. If they agree to return, arrange a visit and note what they do and when. If they refuse or ignore you, get an independent assessment.
6. If the matter is still unresolved, move to a complaint body, your card provider or a court, as set out later in this article.

How should you handle the final payment?

Do not pay the final invoice without a clear plan, but do not stop communicating either. If you pay in full and then complain, you lose most of your bargaining power. A sensible approach is to pay the amount you accept is due for the sound work, then tell the trader in writing which part you dispute, why, and how much you are holding back.

Be honest about the figure. Holding back an arbitrary or unreasonable sum can make your position harder to defend. If you paid by credit card, check with your card provider before you decide how much to hold back, because the card route has conditions of its own.

How do you write a complaint letter that gets a response?

A clear, factual letter is easier for the trader to act on, and it reads well if you later pass it to Citizens Advice, Trading Standards, a card provider or a court. Keep the tone calm. Anger may feel justified, but it gives the trader a reason to dismiss the letter.

Your letter should include:

• Your name, the address where the work was done, and the date of the quote or contract.
• What was agreed, quoting the exact wording from the quote or contract where you can.
• What went wrong, when you first noticed it, and what evidence you have.
• What you want, either repeat work by a stated date or a price reduction of a stated amount, with your reasons.
• A deadline for a reply, and a statement that you will consider further action if the matter is not resolved.

Illustrative closing wording: "If I do not hear from you by the date above, I will refer this matter to the appropriate consumer body and consider my options through the courts." Adapt this to your facts and take advice before relying on it.

Send the letter in a way that gives you proof of delivery, such as email with a read receipt or recorded post, and keep a copy. Do not make threats that you do not intend to follow through, because a court will look at how each side behaved.

What if the trader still will not put things right?

You have several routes, and you do not need to choose only one. Citizens Advice offers free consumer guidance, Trading Standards enforces consumer law locally, a trade body or government-endorsed scheme may have its own complaints process, your card provider may be able to help, and a court can decide money claims.

Trade bodies and alternative dispute resolution

Some trade bodies and schemes offer a complaints route, sometimes called alternative dispute resolution, which is often quicker and cheaper than court. Ask the trader in writing which trade body or scheme they belong to, then check the membership on that body's own website rather than relying on a logo or a certificate you have been shown. Membership is a starting point, not a guarantee of quality. UKListingz does not verify qualifications, insurance or accreditation, and it does not endorse any business.

Card payments and Section 75

If you paid by credit card, section 75 of the Consumer Credit Act 1974 can make the card provider jointly liable for a breach of contract or a misrepresentation by the trader, for purchases costing between £100 and £30,000. Conditions apply, and the rule does not cover every payment, so check with your provider. Your provider may also be able to look at a chargeback, which is a separate process with its own rules. Act promptly, because card providers set their own time limits.

Small claims

If you cannot settle the matter, you may take the trader to court. In England and Wales, the small claims track generally covers claims up to £10,000. Scotland has its simple procedure for claims up to £5,000, and Northern Ireland has its own small claims system. Courts usually expect you to have tried to resolve the dispute first, and a clear letter with your evidence shows that you have. For England and Wales, GOV.UK explains how to start a money claim, and the court service in your nation will set out its own process.

Does the cooling-off period help with poor work?

Not usually. The 14-day cancellation right under the Consumer Contracts Regulations 2013 is about changing your mind after agreeing a contract that was made away from the trader's premises, online or by phone. It is a separate issue from poor workmanship, and cancelling does not fix faulty work you have already received.

The cooling-off rules matter in a different way. If you asked the trader to start within the 14 days, you may have to pay for the work already carried out, and emergency repairs you requested follow different rules. Read our separate guide on the cooling-off period for services before you cancel anything.

What mistakes weaken a complaint about bad workmanship?

Most weak complaints fail for avoidable reasons. These are the ones that come up most often, and each one is easy to prevent.

• Paying the full balance and then complaining, which removes most of your bargaining power.
• Waiting for months before reporting a fault, which makes it harder to prove what caused it.
• Letting another trader alter the work before you have photographs and an independent report.
• Relying on verbal promises that were never written down, such as "we will sort it when we are back".
• Accepting a vague reply with no date, when a specific deadline is what gives your complaint force.
• Sending abusive or threatening messages, which can undermine an otherwise strong case.

How can you reduce the risk of bad work next time?

Most disputes start with a weak agreement. Write down the scope of work, the price basis, the start and finish dates, the payment stages and who buys the materials. A fixed quote, a clear specification and a written list of exclusions protect both sides. Our guide on quote versus estimate explains how to compare written prices properly, and how to find a reliable builder sets out the checks to make before you hire.

Where the work involves gas, electrical or plumbing, check the qualifications that apply before any work starts. Gas engineers should be on the Gas Safe Register, and electrical work carries its own rules in England and Wales under Part P of the Building Regulations. If you need someone for that kind of job, you can browse local electricians or plumbing services by town.

UKListingz is a free directory, and it lists 795,577 active businesses as of November 2026. That makes it a useful place to compare several local firms in one search. The directory does not verify qualifications, insurance or accreditation, so check those yourself. For building work, start with local builders and ask each one for the same written scope before you choose.

Frequently asked questions

Can I withhold payment for bad workmanship?

You can usually hold back the part of the payment that relates to the faulty work, but withholding everything can give the trader grounds to pursue the debt. Pay the undisputed part, tell the trader in writing which amount you are disputing and why, and keep your evidence. If the sum is large, get advice from Citizens Advice before you decide how much to hold back.

How long do I have to make a complaint about poor work?

There is no single deadline that applies to every case, and time limits for court claims can depend on the type of claim and where you live. The practical rule is to report faults as soon as you notice them, because delay makes it harder to prove what caused them. Check GOV.UK and Citizens Advice for the current position before you rely on any time limit.

Does the Consumer Rights Act apply to sole traders?

Yes, in general. The Act covers services supplied by a trader to a consumer, and the trader can be a sole trader, a partnership or a limited company. The key question is whether you bought the work as a consumer, meaning for personal use rather than for a business. Sole traders are personally liable for their business debts, which matters if you need to recover money from them.

Can I pay someone else to fix the work and claim the cost?

Sometimes, but it is risky to act without giving the original trader a chance first. If the fault is a safety risk, make the area safe and keep your evidence, including photographs, the second trader's invoice and a note explaining why you acted. Speak to Citizens Advice before committing to a large repair, and keep receipts for everything.

What can I do if the trader has closed or changed its name?

For a limited company, Companies House shows whether the company is still active and who its directors were. A sole trader does not appear on Companies House, so you will need to trace them through the address and contact details you already hold. A new business run by the same owner can still raise liability questions depending on the facts, so take advice before you assume a claim is lost.

Who should I contact first if the work is dangerous?

If the work creates an immediate danger, such as a gas smell, a live electrical fault or a structure at risk of collapse, deal with the danger first. For a gas leak or smell of gas, call the National Gas Emergency Service on 0800 111 999, which is free and available 24 hours a day, open the windows and avoid switches and flames. For a life-threatening emergency or fire, call 999. Report the defective work once the risk is under control.
