Get your money back when a UK builder leaves work unfinished

If a builder has taken money and left paid work unfinished, you can ask them to complete or fix the job, demand a refund, or—if that fails—bring a civil claim to recover money. How successful you will be depends on what you paid with, the contract and records you hold, and whether the contractor belongs to any warranty or redress scheme. Read on for a practical sequence you can follow, the evidence that matters, and realistic expectations about costs and timings.

What you can reasonably expect to achieve first

First, treat the situation as a civil dispute. Citizens Advice explains that when work isn’t completed you can ask the trader to finish it, ask for a price reduction or a refund, and ultimately take the matter to court if required. See the Citizens Advice guidance on hiring trades and what to keep. (Citizens Advice: Before you get work done on your home).

A few practical realities matter: unfinished work alone does not automatically create a criminal case; prosecutors need evidence of dishonest intent to pursue offences. TrustMark’s guidance for when a builder stops responding explains escalation options such as contacting trading standards, warranty providers or the police when behaviour suggests deliberate wrongdoing. (TrustMark: What to do if Your Builder Stops Responding).

Evidence and paperwork that decide the outcome

What you can prove is what determines whether a demand or a court claim will succeed. Prioritise gathering the following, because courts and payment providers will look for them:

• The contract, written quote or scope of work. A written quote accepted by you is usually a binding agreement. (Citizens Advice).
• Invoices, receipts and proof of payments (card statements, bank transfers).
• A dated chronology of events and communications (texts, emails, letters).
• Photographs showing unfinished work and any damage or materials on site.
• Names, vehicle registrations, and any witness contact details.

If you only have a verbal agreement, you still have rights, but it's harder to prove what was agreed. Citizens Advice emphasises keeping everything in writing wherever possible.

How your payment method changes your options

Payment method materially affects remedies:

• Credit card payments may give you protection under the card issuer’s policies and, in many cases, a Section 75 claim against the card provider for purchases between £100.01 and £30,000, which can secure a refund if the trader has failed to perform. Citizens Advice explains Section 75 and chargeback as separate routes. (Citizens Advice).

• Debit card payments and bank transfers do not attract Section 75. Chargeback via the card scheme may still be possible on debit cards but is discretionary. Bank transfers and cash provide the weakest automatic remedies and usually require a civil claim to recover funds.

If you paid by card, contact your card provider promptly to ask about chargeback and Section 75 (if applicable). Keep a written record of any response.

How to write a demand that increases the chance of repayment

A clear written demand is often the single most useful pre‑court step. Its purpose is to state the problem, the remedy you want, and a reasonable deadline—while creating a paper trail you can use in court. A demand should:

• Summarise the contract/quote, how much you paid and what remains unfinished.
• Attach evidence: photos, invoices, payment receipts and a brief timeline.
• State what you want: completion within X days, a set price reduction, or a refund of £Y.
• Give a reasonable deadline (commonly 7–14 days for a refund or to agree a plan) and say you will consider further action if there is no response.

Keep proof of sending (recorded delivery, email read receipts) and remain factual—avoid threats that suggest bad faith. TrustMark and Citizens Advice both recommend attempting this route before court action. (TrustMark; Citizens Advice).

If the demand fails: ADR, small claims and practical enforcement

If the trader does not respond or refuses, you have a few realistic routes:

• Check whether the contractor belongs to a scheme or offers an insurance‑backed guarantee; those schemes often provide complaints processes or mediation. (TrustMark covers how to use trade schemes.)
• Consider mediation or an alternative dispute resolution service if both sides might negotiate.
• For straightforward money claims, use the small claims or Money Claim Online procedure described by GOV.UK. Be aware of court fees, time, and the fact that a judgment still requires enforcement if the trader refuses to pay. (GOV.UK: Make a court claim for money).

Weigh the likely recovery against the time and cost of court. A judgment can be enforced (bailiffs, charging orders) but enforcement steps have costs and practical limits.

Example: a realistic path for a £2,400 deposit

You paid £2,400 by bank transfer as a deposit for a kitchen refit; the tradespeople left after laying a subfloor and stopped answering messages. Practical steps:

1. Stop any further payments and photograph the site (date-stamped if possible).
2. Send a written demand attaching the original quote, evidence of the £2,400 payment and photos, asking for a full refund within 14 days or for the works to be completed by a specific date.
3. If the contractor paid by card you do not have Section 75 (because you paid by bank transfer)—contact Citizens Advice and your bank about chargeback but prepare to bring a small claim. (Citizens Advice).
4. If no response, start a Money Claim Online action and continue to gather evidence to support your claim. (GOV.UK: Make a court claim for money).

When to get legal or regulatory help

If the amount is large, the facts are contested, or you suspect deliberate wrongdoing, seek a solicitor’s advice. You may also contact your local Trading Standards office if you reasonably suspect serious misconduct. For legal context on consumer service rights, see the Parliamentary briefing on the Consumer Rights Act 2015. (Consumer Rights Act 2015 briefing).

A final practical note: stay calm and keep records. A carefully drafted demand often prompts a prompt settlement; when it doesn’t, the evidence you have gathered will determine whether a small claims action is worth the time and cost.
