Questions to ask before hiring a builder
The key questions for extensions, renovations, structural changes and general building work.
Edited by Lead & Trade using general UK hiring, quoting and platform privacy guidance. This is practical guidance, not legal advice or a guarantee of workmanship.
Scope and responsibility
Ask exactly what is included in the quote, who supplies materials, who manages waste and whether making-good is included.
For structural or larger work, clarify who handles drawings, building control and any required permissions.
Payment and timing
Agree payment stages before work begins. Avoid large upfront payments unless there is a clear materials reason and a written agreement.
Ask what could delay the job and how changes to the scope will be priced.
Proof and protection
Ask for insurance details, examples of similar work and a written quote. A professional builder should be comfortable explaining their process.
Practical checklist
- Write down the job scope, access notes, timing and budget range before asking for quotes.
- Keep your messages, photos, quote changes and payment notes in one place.
- Ask for written details where the work involves safety, certification, specialist materials or staged payments.
- Use Lead & Trade privacy-safe job posting so your full contact details are not public.
