See what your quote shows against the checklist for your job, the paperwork to ask about and when you would pay. Guidance links take you to the source.
- It doesn’t judge the price
The check explains the details and payment terms. It doesn’t tell you whether the price is fair or whether to hire the business.
- No account or email needed
When you get a result, we retain the prices and business details to help build price guides. We don’t keep your own details or notify the business.
Common questions
Before you agree to the work
How much deposit should I pay a builder?
Citizens Advice says to keep the deposit as low as possible and not agree to more than 25%.
Should a quote be a fixed price?
A quote gives an agreed price for specified work. An estimate gives an approximate cost. Citizens Advice recommends getting the quote in writing.
Can I cancel building work I agreed to at home?
If you agree a job in your home, you can usually cancel within 14 days of agreeing it.
This guide covers England. Rules for building work differ in Wales, Scotland and Northern Ireland. It is general information, not legal advice, and it does not say whether a price is fair.
