Building Quote Templates UK: Every Format Builders Actually Use

What format should a building quote be sent in?

Always send a building quote as a PDF. PDF preserves your formatting on any device, cannot be accidentally edited by the client, and looks professional. Create the quote in Word, Excel, or software, then export to PDF before sending. Never send an editable Word or Excel file as your final quote document.

How detailed does a building quote need to be?

A quote should be detailed enough that there is no ambiguity about what is and is not included. For a simple single-trade job, one page may suffice. For a multi-trade renovation, you need trade-by-trade line items, materials versus labour split, and an explicit exclusions list. Vague quotes lead to scope disputes — itemisation protects both the builder and the client.

Do I need to register for VAT to send a building quote in the UK?

No. Any builder can send a quote whether or not they are VAT-registered. If your turnover is below the registration threshold (£90,000 in 2026), you do not charge VAT and should state this clearly on the quote. If you are VAT-registered, you must show net, VAT amount, and gross total. The HMRC CIS scheme applies to subcontractors and affects how deductions appear on invoices, not quotes.

Can a builder change a quote after the client has accepted it?

Once accepted, a quote is a binding commercial offer — you cannot unilaterally increase the price. However, if the client requests additional work outside the original scope, you can issue a variation order at a new agreed price. This is why a clear exclusions list in your original quote is essential: it defines the boundary of the fixed price and provides the legal basis for charging extra for out-of-scope work.

What is the difference between a quote, estimate, and tender in UK construction?

A quote is a fixed price offer for a defined scope — legally binding once accepted. An estimate is an approximate figure that can change as work progresses. A tender is a formal competitive bid submitted in response to a client brief, often for larger projects. Most domestic builders use quotes. Tenders are more common for commercial or public sector work where formal procurement rules apply under the planning and procurement framework.

How should I handle material price increases mid-job?

Include a validity period on every quote — typically 30 days. If materials rise significantly after the quote is accepted but before work starts, the situation depends on whether a contract has been signed. A well-drafted contract includes a materials fluctuation clause that allows prices to be reviewed if costs rise beyond a stated threshold. The HSE construction guidance also recommends pre-contract clarity on price adjustment provisions for longer projects.

Should a building quote include a contingency?

On renovation work — particularly older properties — a contingency of 10–15% is recommended. Hidden structural issues, unexpected pipework, or asbestos found during strip-out can significantly increase costs. You can either include the contingency in your quote as a named line item (transparent) or build it silently into your trade rates (common but less professional). Including it as a named line item is better practice: it shows the client you are planning carefully. For projects subject to planning consent, note that the Planning Portal is the authoritative source for checking whether work requires approval before it starts.
