Is this a red flag? Check your builder and quote
Not sure whether your builder or their quote is trustworthy? Tick anything below that is true, and this free tool tells you which are genuine warning signs, how serious each one is, and exactly what to do about it. No sign-up, and nothing is sent anywhere.
Tick anything that is true of your builder or their quote:
The golden rules
- Get the price, scope, materials, timeline and payment schedule in writing before any money or work. Our free builder contract template covers it.
- Never pay a big deposit. Stage payments to work actually completed, and hold a final amount back until snags are fixed.
- Check registration and insurance: Gas Safe for gas, Part P for electrics, and public liability cover before they start.
- Get three quotes, do not be rushed, and compare them fairly before you decide.
This is free guidance to help you spot warning signs and ask the right questions, not legal advice. It does not see or store anything you tick.
