Give every builder the same information
The aim is simple: make sure each builder is pricing the same job. A clearer brief reduces the number of assumptions hidden inside a quotation and makes it easier to compare one quote with another.
For larger or regulated work, the homeowner brief does not replace professional drawings, calculations, specifications or approvals. Use the appropriate architect, engineer, surveyor, building control professional or qualified trade where required.
Useful rule: if an important decision could materially change the price, either define it before asking for quotes or label it clearly as an allowance / decision still to be made.
Your builder quote information pack
What should you ask the quote to show?
A detailed written quote should let you understand the basis of the price, not just the total. Ask for the scope, major labour and material elements, VAT position, included fixtures and finishes, exclusions, allowances or provisional costs, waste removal, programme, payment stages and how changes will be agreed and priced.
For substantial work, also ask who will manage the project, who will be on site, relevant insurance, experience of similar work, references, guarantees or warranties, and the expected start and duration.
Quote or estimate?
UK consumer guidance distinguishes between a written quotation and an estimate. An estimate is generally a best indication of likely cost, while a quote is a more definite price for a defined scope. Always read the trader's wording and terms, and keep the accepted information in writing.
Compare the detail, not only the cheapest total
Two quotes can differ because they contain different assumptions. Compare what is included and excluded, which products or allowances have been used, VAT, programme, payment stages and responsibility for other trades. If one figure is much lower, find out why before deciding.
For the wider planning process, see our home improvement planning guide and home improvement budget guide. If the project is a kitchen, the kitchen project planning guide helps organise the choices before quotations are requested.

Questions homeowners often ask
What information should I give a builder for a quote?
Give the same clear brief to every bidder: scope, relevant drawings or specifications, chosen products and finishes, undecided items that need allowances, approvals where relevant, timing, access constraints and who will supply or manage major items.
How many builder quotes should I get?
For material work, UK guidance commonly recommends comparing around three detailed written quotes from suitable builders, rather than approaching a very large number of firms.
What should I compare besides price?
Compare scope, inclusions, exclusions, VAT, allowances, start date, duration, payment stages, experience, references, insurance and how additional work will be approved and priced.
Should I give builders my budget?
A working budget can help a builder tell you whether the proposed scope and quality level are realistic. You can still ask for a detailed breakdown so you understand how the price has been built up.
