What a professional builder's quote should include

A building quote does two jobs at once. It tells the client what they are buying, and it protects the builder when the job gets complicated. Here is every section a proper quote should carry, and why each one earns its place.

The quote is the first thing you build

Before a single brick is laid, the quote is the only evidence a client has of how you work. A clear, complete document says "this person is organised and will run my job the same way." A single number on a text message says the opposite, even when the price behind it is perfectly sound.

For homeowners reading this, the same anatomy works in reverse. If the quotes on your kitchen table include the sections below, you are comparing serious businesses. If they do not, you are comparing guesses.

The header: who, what, where, when

The top of the document should answer the basics without anyone having to ask:

• Your trading name, company number if you have one, and contact details
• The client's name and the full site address
• A quote reference and the date it was issued
• A validity period, commonly 30 days, so material price movement cannot quietly eat your margin
• A one-line description of the project, for example "single storey rear extension, approx 18 square metres"

The validity line matters more than most builders think. Materials move. A price given in March and accepted in August is a different job wearing the same number.

Scope: say what you will actually do

The scope section is the heart of the quote. It should list the work by element, in the order the job will run: demolition and strip out, groundworks, drainage, masonry, structural openings, roof, windows and doors, first fix, plastering, second fix, decoration, external works. Each line should say enough that a stranger could tell whether an item is included.

"Supply and fit kitchen" is not scope. "Fit client's kitchen supplied by others, including connection to existing services, worktops by specialist" is scope. The difference between those two sentences is where most disputes are born.

Where you have quantities, show them. "Facing brickwork, approx 38 square metres, in brick to match existing" reads very differently from "brickwork", and it gives you solid ground to stand on if the wall grows a metre during the job. The same goes for named products and finishes: a quote that says which boiler, which windows and what grade of insulation is a quote that cannot be undercut by someone silently pricing worse versions of all three. Specificity feels like extra work on a Tuesday night, but it is the cheapest sales advantage and the cheapest legal protection you will ever buy.

Exclusions and assumptions: the fence around your price

Every price is built on assumptions, so write them down. Ground conditions assumed normal. Existing drainage assumed serviceable. Client to supply sanitaryware. No allowance for asbestos removal. These lines are not weasel words, they are the fence around your number, and a good client respects a builder who marks the boundary honestly. We cover this in depth in exclusions and assumptions: the small print that saves jobs.

The money section: breakdown, VAT, payment stages

Three things belong here, and each is a common failure point:

Get the VAT line right first time, every time. If you are near the registration threshold, that is a business conversation worth having before the quote goes out, and we have written a full guide to quoting VAT on building work. Payment stages deserve equal care: milestones such as "watertight" or "first fix complete" are visible, checkable moments, which makes them easy for a client to pay against. There is a full walkthrough in stage payments that protect your cash flow.

The finishing touches that win the job

Beyond the essentials, a handful of small additions separate the quotes that win from the quotes that sit in inboxes:

• A programme estimate. Even "approximately 10 to 12 weeks on site" answers the question every client is silently asking.
• Insurance details. Public liability cover stated plainly builds trust in one line.
• How variations will be handled. One sentence saying changes will be priced and agreed in writing before work proceeds saves the relationship later.
• A clear next step. "To accept, sign and return this page" turns a document into a decision.

None of this needs to take hours. This is exactly the gap QS Quoter was built to close: describe the job or upload the drawings, and it produces a clean client quotation plus a private tradesman copy with your own rates behind every line. The structure above is baked in, so every quote you send looks like the work of the organised builder you actually are.
