Free Builder Quote Template UK (2026) — Editable & Professional

What a Professional Builder's Quote Must Include

A builder's quote for any project of meaningful size should cover the following as a minimum. Omitting any of these creates gaps that can cost you money or create disputes.

1. Your business details — trading name, address, phone, email, UTR number (sole traders) or company registration number (Ltd), and VAT number if registered
2. Customer details — full name, home address, and the site address if the works are at a different property
3. Quote reference number and date issued — a simple sequential number (e.g. QT-2026-047) makes filing and follow-up straightforward
4. Valid until date — 30 days from the date of issue is standard; beyond this, material prices and your availability may have changed
5. Detailed scope of work broken into sections— for example, Groundworks, Brickwork, Roofing, Windows & Doors, First Fix, Plastering, Decoration; each section should describe what is included
6. Labour line items — either as a fixed price per section, a day rate multiplied by estimated days, or a combined labour cost per section
7. Materials line items— either itemised per section or as a combined line per section; specify brand or specification where it affects the customer's decision
8. Exclusions — be explicit about what is NOT included: structural engineer fees, planning fees, party wall surveyors, making good decoration after chasing, disposal of hazardous materials, any specialist subcontractor work not mentioned
9. Payment terms — for larger jobs, break this into stage payments tied to visible milestones (e.g. roof completion, plastering completion); always specify your deposit requirement
10. VAT treatment— if registered, show net total, VAT at 20%, and gross total as separate lines; if not registered, state "VAT not applicable — not VAT registered"
11. Your signature, printed name, and date — signing the quote shows professionalism and makes the document feel like a formal proposal

The exclusions section is the one most commonly skipped, and it is the one that causes the most disputes. If you do not write down that your price excludes the structural engineer's calculations, the customer will assume you have factored that cost in. A thorough exclusions list protects you and makes your quote easier for the customer to compare fairly against others.

The example below shows a realistic quote for a single-storey kitchen extension. Adapt the sections and figures for your own job. The structure works for any building project from a garage conversion to a two-storey rear extension.

Common Mistakes with Builder Quotes

Most disputes between builders and customers come back to one of a small number of easily avoidable errors in the original quote.

• Not including exclusions. If your quote does not say that structural engineering fees, floor finishes, or decoration are excluded, the customer will assume they are included. Write down everything that is outside your price — it saves an ugly conversation when the invoice arrives.
• No payment terms. For anything over a few thousand pounds, agreeing the payment schedule in the quote protects you from cash flow problems mid-project. A customer who has not paid stage two has no leverage over stage three — but only if the schedule was agreed upfront.
• Not separating materials from labour. When the invoice arrives, customers sometimes try to dispute the materials cost if they feel they could have sourced them cheaper. Showing labour and materials as separate line items makes it clear what you are charging for each element and makes negotiation easier if the customer wants to supply their own materials.
• Missing VAT status. If you are VAT-registered, the quote must show net, VAT, and gross as separate lines. If you are not, never mention VAT. Charging VAT when unregistered is illegal. Getting this wrong creates confusion and can cause HMRC issues.
• No validity date. A quote without an expiry date can be accepted months later at the original price — even if timber has gone up 15% in the interim. Always include a 30-day validity period.

Quote vs Estimate: The Legal Difference

In UK contract law, a quote(or quotation) is a fixed offer. Once the customer accepts it — even by a simple email reply saying "please go ahead" — a contract is formed at that price. You cannot raise the price after acceptance unless unforeseen work arises that was genuinely outside the scope described in the document.

An estimate is an approximation. It signals that the final price may differ from the figure given, typically because the full extent of the work cannot be determined until it is underway. Estimates are common for investigative or remedial work — for example, re-pointing a chimney where the full extent of the damage is not visible until scaffolding is up.

In practice, many builders use the words interchangeably. This is a mistake. If your document is headed "Quotation" but you later try to add 20% to the final invoice, the customer has strong grounds to refuse. If it is headed "Estimate" and you come in exactly on the figure, the customer will treat it as a fixed price anyway.

The safest approach is to use fixed quotes wherever the scope is reasonably well defined, and to issue estimates only for genuinely open-ended investigative work — with a clear note on the document explaining why the final cost may vary and how you will notify the customer before any variation is actioned.

How to Send the Quote

Send your quote as a PDF by email — not as a WhatsApp message, a text, or a verbal price on the doorstep. A PDF on headed paper looks significantly more professional, is easy for the customer to forward to a partner or mortgage broker, and gives you both a document to refer back to.

Timing matters. Send the quote the same day as the site visit, or at the very latest within 24 hours. Customers typically contact three or four builders simultaneously. Whoever responds first and most professionally often wins the job, regardless of price. A quote that arrives five days after the site visit signals poor organisation — and customers extrapolate from that to how you will run the job itself.

Follow up by phone three days after sending. A simple call — "Just checking the quote arrived okay and to see if you have any questions" — converts a meaningful proportion of quotes that would otherwise go cold. Most customers are not ignoring you; they are just busy. A brief follow-up reminds them to make a decision and gives you the chance to address any concerns before they go with someone else.

Adjusting Your Quote for Location

Labour costs vary significantly across the UK. When completing your quote template, use regional rates that reflect your local market — not national averages.

When a Customer Wants to Negotiate

When a customer pushes back on price, the single most important principle is to reduce scope, not margin. Never agree to do the same job for less money. Instead, ask the customer what they would like to remove from the scope to bring the cost down. This has two effects: it makes clear that your original price was fair for the work it covered, and it shows the customer that you cannot simply conjure money from thin air.

A useful conversation goes like this: "I can get closer to your budget if we defer the bifold door and fit a standard French door for now — that saves around £1,800. The opening is already built so you could upgrade later. Would that work?" This protects your margin entirely while giving the customer a genuine option.

If the customer is comparing you to a significantly cheaper quote, ask to see the scope of that quote before responding. In most cases, the cheaper quote has different exclusions, different materials specifications, or has simply not priced the contingency. Talking through what your quote covers that theirs does not is a far stronger sales conversation than matching their price.
