Free Plumber Quote Template (UK) — With a Worked Example

What a plumber's quote must include

A quote is more than a price. To look professional and protect yourself if there is a dispute later, every plumbing quote should contain a core set of details. Missing any of them is one of the most common reasons quotes get questioned or rejected.

Your business details: trading name, contact number, email, and address. If you are Gas Safe registered, include your registration number — it builds instant trust for boiler and gas work.

The customer's details and the job address: so there is no confusion about which property the work covers.

A unique quote number and the date: this makes the quote easy to reference and shows you run an organised business.

A clear description of the work: what you will do, and just as importantly what is not included. "Supply and fit new mixer tap" is clear; "do the bathroom" is not.

An itemised breakdown: labour, materials, and any call-out or disposal fees listed separately so the customer can see where the money goes.

The total price, and whether it includes VAT: if you are VAT registered, show the net amount, the VAT, and the gross total.

Validity period: how long the price holds — 30 days is standard. Materials prices move, so this protects you.

Payment terms: deposit required, when the balance is due, and accepted payment methods.

A free plumber quote template (worked example)

Here is a worked example for a common job — replacing a hot water cylinder — so you can see how the pieces fit together. Adjust the figures to your own rates and region.

Job: Supply and install replacement 210L unvented hot water cylinder, including removal and disposal of the old unit.

Line 1 — Labour: Remove old cylinder, install and commission new unvented cylinder. 6 hours @ £55/hour = £330.00.

Line 2 — Materials: 210L unvented cylinder (supply). 1 @ £620.00 = £620.00.

Line 3 — Materials: Tundish, expansion vessel, valves and fittings. 1 lot @ £85.00 = £85.00.

Line 4 — Call-out / disposal: Removal and certified disposal of old cylinder. 1 @ £40.00 = £40.00.

Subtotal: £1,075.00. VAT (20%, if registered): £215.00. Total: £1,290.00.

Notice how every cost is visible. The customer is not being asked to trust a single mysterious number — they can see exactly what they are paying for, which makes the price far easier to accept.

How to price common plumbing jobs

Pricing is the part most plumbers find hardest. The reliable method is to build the price up from its parts rather than guessing a round figure.

Start with labour: estimate the hours realistically, including travel and clean-up, and multiply by your hourly rate. If you work to day rates, use those instead.

Add materials at your actual cost, then apply a sensible markup (commonly 10–20%) to cover the time spent sourcing, collecting and guaranteeing them.

Add call-out, parking, congestion charges and waste disposal where they apply — these small costs add up and are easy to forget.

Build in a contingency for the unexpected on older properties, and be explicit about what would trigger a variation to the price (for example, hidden corrosion or non-standard pipework).

Finally, sense-check the total against what the job is worth and what your local market will bear. Pricing too low to win work is a common trap — it erodes your margin and attracts the most demanding customers.

Quote or estimate? A quick legal note for UK plumbers

In the UK a quote is generally treated as a fixed price that, once accepted, forms a binding contract. An estimate is an educated guess that can change as the job unfolds. If you give a fixed quote and then charge more without agreement, the customer can refuse to pay the extra.

For well-defined jobs (replace a tap, fit a cylinder) a quote is appropriate. For open-ended work where you cannot see everything in advance (chasing a leak inside a wall), an estimate with clear wording about what could change is safer. Whichever you use, label it clearly on the document.

Frequently asked questions

Do plumbers have to charge VAT in the UK?

Only if you are VAT registered. You must register once your taxable turnover exceeds the VAT threshold (£90,000 as of April 2024), and you can register voluntarily below that. If you are registered, you charge VAT (usually 20%) on your work and show it on your quotes and invoices. Check the current rules with HMRC or your accountant.

What should a plumber's quote include?

Your business and contact details, the customer and job address, a unique quote number and date, a clear description of the work, an itemised breakdown of labour and materials, the total price and whether it includes VAT, how long the quote is valid, and your payment terms.

Is a plumbing quote legally binding?

Once a customer accepts a fixed-price quote, it generally forms a binding contract in the UK, so you cannot increase the price without their agreement. An estimate is not a fixed price and can change. Always label the document clearly as a quote or an estimate.

How long should a plumbing quote be valid?

Thirty days is the common standard. Because materials prices fluctuate, stating a validity period protects you from being held to an old price weeks or months later.
