Choosing the right builder is the single most important decision in any construction project. Here's our honest advice on what to look for and what red flags to avoid.
Check credentials and insurance: Any reputable builder should carry public liability insurance (minimum £2 million) and employer's liability insurance. Ask to see certificates, not just claims. Membership of trade bodies like the FMB, NHBC or a TrustMark-registered scheme adds credibility.
Look at previous work: Ask for examples of completed projects similar to yours. Visit sites if possible. A confident builder will be happy to show their work and provide references from recent clients.
Get detailed, written quotations: A professional quote should itemise materials, labour, timelines and payment schedules. Be wary of vague estimates or quotes that seem too good to be true — they usually are.
Communication matters: How a builder communicates before the job starts tells you everything about how they'll communicate during it. Prompt responses, clear explanations and honest advice are non-negotiable.
Avoid these red flags: demanding large upfront payments, no written contract, reluctance to provide references, pressure to start immediately, and no fixed address or landline.
