A building quote is not just a price. It is the document that tells the customer you understand the drawings, have priced the hidden work, know which trades are needed, and can manage the job properly. A vague one-line quote might be quick to send, but it leaves too much room for confusion, unpaid extras, and margin slipping away.

This builder quote template is written for UK builders quoting extensions, refurbishments, garage conversions, structural alterations, and larger domestic projects. Use it as a practical framework for clearer pricing, better customer trust, and fewer disputes once work starts.

Builder Quote Template: What to Include

A professional building quote should be clear enough for a homeowner to understand and detailed enough to protect your business. Include these sections every time:

  1. Your business details - business name, phone, email, address, logo, insurance details, VAT number if registered.
  2. Customer and site details - customer name, site address, quote number, quote date, and main contact.
  3. Documents referenced - drawings, structural calculations, specification notes, schedule of works, and revision dates.
  4. Scope of works - exactly what you are supplying, installing, managing, and finishing.
  5. Itemised costs - labour, materials, subcontractors, plant hire, waste, scaffolding, and preliminaries.
  6. Provisional sums - allowances for items not fully selected yet, such as kitchens, bathrooms, tiles, or finishes.
  7. Exclusions - planning fees, Building Control, party wall awards, decoration, flooring, landscaping, or client-supplied items if not included.
  8. Payment schedule - deposit and milestone payments tied to visible progress.
  9. Quote validity - usually 14 to 30 days because material and subcontractor prices can move quickly.

Quick win: The quote that explains the job usually beats the quote that only gives a number. On bigger building projects, confidence is part of what the customer is buying.

Copy-and-Paste Builder Quote Wording

Use this wording as a base, then adjust it to match the job:

Section Example wording
Scope Supply labour, materials, plant, waste removal, and project coordination for the proposed single storey rear extension as per drawings dated 15 May 2026.
Assumptions Quote assumes clear access to rear of property, standard ground conditions, existing services marked by client, and no asbestos or hidden structural defects.
Exclusions Quote excludes planning fees, Building Control fees, party wall surveyor costs, kitchen supply, floor finishes, decoration, and unforeseen works unless stated below.
Variations Any change to agreed scope, drawings, finishes, or client selections will be priced and approved in writing before additional work is carried out.
Payment terms 10% deposit to secure start date, followed by staged payments at agreed project milestones, with final balance due on practical completion.

Itemised Extension Quote Example

This example is for a small single storey rear extension with standard finishes. The figures are illustrative and should be adjusted for your region, access, specification, drawings, ground conditions, and subcontractor prices.

Work package What is included Example cost
Preliminaries Site setup, protection, welfare, project admin, supplier coordination £1,250
Groundworks Excavation, foundations, oversite, drainage alterations, muck away £6,800
Shell construction Brick/blockwork, cavity insulation, lintels, structural openings £8,950
Roof and weatherproofing Flat roof structure, insulation, covering, fascia, guttering £5,400
Windows and doors Supply and fit aluminium bi-fold doors and one roof lantern allowance £5,750
First and second fix trades Electrical points, lighting, radiator pipework, plasterboard, skim finish £7,600

Total fixed price Excluding VAT and client-selected kitchen, flooring, and decoration £38,000

Staged Payment Schedule Example

Builders should not finance the whole job from their own pocket. A fair staged payment schedule keeps your cash flow healthy while giving the customer clear progress markers.

Stage Payment trigger Example percentage
Deposit Start date secured and materials ordered 10%
Groundworks Foundations excavated, poured, and inspected 20%
Shell Walls built, openings formed, structure progressing 25%
Watertight Roof covering, windows, doors, and external envelope complete 20%
First/second fix Services, plastering, joinery, and finishing works underway 20%
Completion Snagging agreed and practical completion reached 5%

How to Price Building Work Without Losing Margin

The danger with building quotes is not only underpricing the labour. It is forgetting the small costs that appear every week on site. Build your price from these blocks:

  • Labour: Estimate days by stage and apply your real builder day rate, including supervision time.
  • Materials: Use supplier prices, allow for waste, delivery charges, and likely price movement.
  • Subcontractors: Get written prices from electricians, plumbers, plasterers, roofers, and scaffolders before sending your own quote.
  • Plant and waste: Include skips, grab lorries, mixers, breakers, scaffold, towers, and temporary protection.
  • Admin and overhead: Quotes, site visits, phone calls, insurance, vans, fuel, tools, bookkeeping, and follow-up are real costs.
  • Profit: Add margin after costs. Profit is what keeps the business alive when jobs run tight.

Variations and Extras: Protect Yourself Early

Most disputes start with a sentence like "I thought that was included." Your quote should make variations simple:

  • Write that changes must be approved before work starts.
  • Price extras separately with labour, materials, and impact on programme.
  • Keep a record of client approvals by email, PDF, or WhatsApp.
  • Do not bury major exclusions in tiny text.

For complex jobs such as loft work, use the same discipline in our loft conversion quoting guide.

Common Builder Quote Mistakes

  • No specification reference: If drawings change, your price needs a fixed reference point.
  • Missing exclusions: Decoration, flooring, kitchen supply, making good, and landscaping often cause arguments.
  • Weak payment terms: A vague "pay as we go" arrangement creates stress for both sides.
  • Not separating allowances: Client-selected items should be shown as allowances or provisional sums.
  • Sending the quote too late: On high-value work, the first clear professional quote often frames the decision.

Frequently Asked Questions

What should a builder quote include?

A builder quote should include the customer details, site address, scope, drawings referenced, labour, materials, subcontractors, plant, waste, exclusions, payment terms, quote validity, VAT status, and total price.

How detailed should a building quote be?

For small jobs, a clear scope and itemised total may be enough. For extensions, renovations, and structural work, break the quote into work packages so the customer can understand foundations, shell, roof, services, plastering, finishing, waste, and allowances.

Should builders use fixed prices or day rates?

Day rates work for maintenance, investigation, and open-ended repair work. Fixed prices usually work better for extensions, conversions, and planned refurbishments because the customer knows the budget and the builder can price for profit.

How long should a builder quote be valid for?

Most UK builder quotes are valid for 14 to 30 days. Material prices, subcontractor availability, and fuel costs can change, so the validity period should be shown clearly.
