You've paid money. The work has stopped, or the quality is unacceptable, or the builder has simply stopped answering their phone. This is one of the worst situations a homeowner can find themselves in, and it's more common than many people realise. Trading Standards receives thousands of complaints about rogue builders every year. Knowing what to do, in the right order, significantly improves your chances of getting resolution.
Before anything else: stay calm. Angry confrontations at the site, threatening messages and social media posts can all undermine your legal position. Document everything. Be methodical. That's what actually works.
Step One: Document the Current Situation
Before you do anything else, create a clear record of where things stand. This means:
- Photographing all work completed, including any visible defects or unfinished elements
- Compiling every payment you've made, with bank statements or receipts
- Printing every written communication: emails, text messages, WhatsApp messages
- Writing a chronological timeline: when work was supposed to start, when it started, key milestones, when problems began
- Noting the names and contact details of any witnesses, including neighbours who may have observed the builder's attendance or absence
This documentation is the foundation of every subsequent step. Without it, you're relying on your word against theirs.
Step Two: Formal Written Notice
If you haven't already issued a formal written notice, do so now. This is different from a WhatsApp message or a phone call. Write a letter (sent by recorded delivery) or a formal email that sets out:
- Exactly what the problem is, with specific reference to the contract if you have one
- What you require them to do to resolve it
- A reasonable timeframe (typically 14 days for a response, 28 days to begin remediation)
- A clear statement that you will take further action if they fail to respond
Keep the tone professional. You're building a paper trail. "I'm going to make your life hell" is not useful. "Unless you return to site by [date] to complete the agreed works, I will seek professional advice and pursue all available remedies" is.
Step Three: Contact Their Trade Body
If your builder is a member of a trade body such as the Federation of Master Builders (FMB), TrustMark, Which? Trusted Traders, or a specialist body like the NICEIC or Gas Safe Register, contact them. Trade body membership typically includes access to a dispute resolution service, which can be faster and cheaper than going through the courts.
The FMB, for example, operates an independent Alternative Dispute Resolution (ADR) scheme for disputes between member builders and their clients. If the builder is a member, they're obligated to participate. A resolution through the FMB scheme can be reached in weeks rather than months.
The leverage here is real: a member who refuses to engage with their trade body's dispute process risks losing their membership, which is commercially damaging for them.
Step Four: Trading Standards and Citizens Advice
Report the situation to your local Trading Standards via the Citizens Advice consumer helpline (0808 223 1133 in England). Trading Standards can investigate where there's evidence of fraud, misrepresentation or systematic wrongdoing. They can also confirm whether the trader has previous complaints against them.
Citizens Advice itself can provide guidance on your legal rights under the Consumer Rights Act 2015 and advise on whether your situation warrants further action. This step doesn't cost you anything and can be genuinely helpful in clarifying your options.
Step Five: Adjudication or Mediation
If you have a JCT contract, adjudication is available to you. An adjudicator is an independent construction professional who reviews submissions from both sides and makes a binding decision, typically within 28 days. It's faster than litigation but not cheap: adjudicator fees can run to several thousand pounds, plus legal costs if you use a solicitor to prepare your submission.
Mediation is less formal and often cheaper. A mediator doesn't make a binding decision but helps the parties reach a negotiated settlement. For disputes under around £25,000, mediation through a provider like RICS or the Centre for Effective Dispute Resolution (CEDR) can resolve matters in a day.
Before adjudication: Get a preliminary assessment from a construction solicitor or a quantity surveyor. They can tell you quickly whether your claim has merit, what it might be worth, and whether the cost of adjudication is proportionate to the amount in dispute.
Step Six: Small Claims Court
For disputes under £10,000 in England and Wales (£5,000 in Scotland), the Small Claims Court (part of the County Court) is accessible without a solicitor and relatively inexpensive to use. You file a claim online at gov.uk, pay a filing fee based on the amount claimed, and the matter is heard by a district judge.
The advantage is cost: you don't need legal representation. The disadvantage is time: it can take six to twelve months, and the process requires you to present your case clearly and coherently. Good documentation from step one is essential.
For disputes over £10,000, legal representation becomes advisable and costs increase substantially. At this level, a construction solicitor is worth consulting early to assess whether litigation or adjudication is more appropriate.
If the Builder Goes Insolvent
This is the worst outcome. If the contractor becomes insolvent while holding your money or with work unfinished, your options narrow significantly. You may be an unsecured creditor in any insolvency proceedings, which typically means recovering little or nothing.
If you paid by credit card for any part of the work (or deposit), you may have a Section 75 claim against your card provider for the outstanding amount, up to £30,000 per claim. This is worth pursuing immediately.
If the contractor held a TrustMark approval or was a member of a consumer protection scheme with a deposit guarantee, contact the scheme directly. Some provide limited protection for consumer deposits in cases of insolvency.
Going forward: never pay more than 10-20% upfront for any domestic building project. Stage payments tied to completed work are the best protection against exactly this scenario.
What Good Documentation Enables
If you're reading this before you've had a problem, not after: the single most important thing you can do to protect yourself is maintain a site diary and photograph record from day one. Keep every payment confirmation and every written communication. Make sure your contract references your specification documents precisely.
None of this prevents a rogue builder from attempting to take advantage of you. But it makes it dramatically more likely that, if they do, you can recover something.
