How to Write a Construction Quote in the UK
A step-by-step guide to writing professional construction quotes that win work. Covers what to include, common mistakes, and the difference between quotes, estimates and invoices.
Why your construction quotes matter
A well-written quote does more than state a price. It sets expectations, protects you from scope creep, and shows clients you run a professional operation. For many homeowners, your quote is the first real impression they get of your business.
Yet a surprising number of tradespeople still send quotes on the back of a text message or a scribbled note. If you want to win more work and avoid costly disputes, it pays to get your quoting right from day one.
What every construction quote should include
1. Your business details
Start with the basics: your trading name (or company name), registered address, phone number, and email. If you are VAT registered, include your VAT number. If you operate as a limited company, include your Companies House registration number.
This is not just good practice. Under the Companies Act 2006, limited companies must display their registered name and number on business documents, including quotes.
2. Client details
Include the client's full name and the site address where the work will be carried out. If the billing address differs from the site address, note both. This avoids confusion later, especially on larger domestic projects.
3. A clear scope of work
This is the most important section. Describe exactly what you will do, broken down into logical phases or areas. Be specific:
- "Strip existing kitchen, remove waste, supply and fit new kitchen units as per layout drawing ref. KD-01" is far better than "fit new kitchen".
- List individual tasks so the client can see what they are paying for.
- Reference any drawings, specifications, or schedules the quote is based on.
4. Exclusions
Equally important is what you will not do. Common exclusions include:
- Structural work or building control applications
- Decoration and finishing beyond the specified scope
- Removal of asbestos-containing materials
- Works to existing plumbing or electrics (unless stated)
- Skip hire or waste disposal beyond a specified amount
5. Pricing breakdown
Clients appreciate transparency. Rather than a single lump sum, consider breaking your price down:
- Materials: itemise the main material costs, or at least group them by trade or phase
- Labour: show the labour cost separately so the client understands the split
- Preliminaries: scaffolding, skip hire, welfare, or any other site costs
- Contingency: if appropriate, include a contingency allowance (typically 5-10%) and explain what it covers
6. Payment terms
State when you expect to be paid and how. Common approaches include:
- A deposit on acceptance (typically 10-20% for domestic work)
- Stage payments tied to milestones (e.g., "30% on completion of first fix")
- Final payment within 14 or 30 days of practical completion
7. Validity period
Quotes should have an expiry date. Material prices fluctuate, and you do not want to be held to a price you gave six months ago. A validity period of 30 days is standard. For larger projects, 14 days may be more appropriate.
8. Terms and conditions
At minimum, cover:
- What happens if the client changes the scope (variation process)
- Your right to extend the programme for reasons outside your control
- Cancellation terms
- How disputes will be resolved
- Your insurance and warranty arrangements
Quote vs estimate vs invoice
These three terms are often confused, but they mean different things:
Quote: a fixed price for a defined scope of work. Once accepted, you are legally bound to that price (unless variations are agreed). This is what most clients expect.
Estimate: an approximate cost based on your best assessment. It is not legally binding, but it should be reasonably accurate. Use estimates when the scope is uncertain, for example when you cannot see behind walls until demolition begins.
Invoice: a request for payment after work has been completed (or at an agreed stage). It is not a pre-work document.
If you provide an estimate, make it clear in writing. Use the word "estimate" prominently and explain that the final cost may differ.
Common quoting mistakes
Underpricing to win the job
It is tempting to go in low, but underpricing leads to cutting corners, disputes, and thin margins. Price the job properly, include your overheads and profit, and compete on quality and professionalism instead.
Vague scope descriptions
"Bathroom renovation" is not a scope. Be specific about every element: sanitary ware, tiling area, plumbing modifications, electrical work, ventilation, decoration. If it is not in the scope, it is not in the price.
Forgetting to account for waste and disposal
Skip hire, tip charges, and the time spent loading and transporting waste all add up. Many tradespeople absorb these costs without realising how much they eat into profit.
Not following up
You sent the quote, now what? Follow up after a few days. A polite phone call or email can make the difference between winning and losing the work. Many clients are comparing multiple quotes and a follow-up shows you are keen.
Sending quotes late
If a client has asked three contractors to quote and you are the last to respond, you are already at a disadvantage. Aim to turn quotes around within 48 hours of the site visit.
