For UK gas engineers
Gas engineer quote template (UK)
A clear layout for a gas quote that puts your Gas Safe registration number up front and sets out scope, parts, flue works and VAT properly, so the customer knows what is included before you touch the gas.
What a gas engineer quote should include
A gas quote carries something a plumbing quote does not: your Gas Safe registration. Gas work in the UK must be carried out by a Gas Safe registered engineer, and putting your registration number on the quote is the first thing that tells a customer they are dealing with a proper business. Beyond that, a good gas quote prices the appliance and the visible work firmly, and handles the hidden work, the gas supply and the flue honestly.
- Your business and Gas Safe registration. Trading name, address, contact, and your Gas Safe registration number in plain sight. Add your VAT number if registered.
- The customer and the site. Their name and the property address, and whether it is an owner occupier or a rented property.
- A specific scope. The exact appliance, the make and model, removal of the old unit, and the finish standard.
- Labour, appliance and parts. Your day rate, the boiler, cooker, hob or fire named, plus the flue kit, filter, valves and fixings that make up the price.
- Gas and flue works. Any gas supply upgrade, pipe sizing, flue type and flue routing, so the customer sees why the figure is what it is.
- VAT. If registered, subtotal, 20% VAT and total. If not, say so.
- Timeline. Days on site and whether heating or hot water will be off at points.
- Payment terms. When you expect payment and any deposit against ordered appliances or parts.
- Exclusions. Making good, decoration, electrical works and any tiling are often excluded. Say so clearly.
- Validity period. "Valid for 30 days" so an appliance price does not follow you around after supplier costs move.

Scope note: "Remove existing boiler, supply and fit new boiler with filter and valves, upgrade gas supply as needed, run and terminate flue to correct type, commission, test and register the manufacturer warranty. Excludes making good, decoration and electrical works." Terms note: "Price assumes the existing gas supply, flue route and system water are suitable. Any defect found on removal, an undersized gas pipe or a heavily fouled system needing a power flush, will be quoted and agreed in writing before proceeding. Valid for 30 days."
The mistakes that cost gas engineers money on a quote
- Leaving off your Gas Safe number. It is the one detail a customer looks for, and it separates you from anyone quoting who should not be near a gas appliance. Put it on every quote.
- Pricing an unknown gas supply. A boiler swap can turn into a supply upgrade when the existing pipe is undersized for the new appliance. Add a clear variations line for gas and flue.
- Vague scope. "New boiler" invites the customer to expect a power flush, new radiators or making good you never priced. Spell out what is in and what is out.
- Forgetting the flue. Flue type and routing drive both safety and cost. Name the flue works rather than folding them into a single figure.
- Confusing a quote with an estimate. A quote is a fixed price. An estimate can move. Label the document as one, never both. See quote vs estimate.
Should a gas engineer send a quote or an estimate?
For a defined job, a fixed boiler swap to an agreed appliance and flue plan, quote it firmly. For a fault where the true cause is not known until you diagnose it, an intermittent lockout or a leak of unknown source, an estimate for the diagnosis with a firm quote to follow is the honest approach. The same applies to a landlord gas safety record, or CP12, where the visit is a fixed price but any remedial work found is quoted separately. Put the scope and variations in writing either way. Our guide to quote vs estimate for UK trades explains when each is fairer.

Gas engineer quote FAQ
What should a gas engineer quote include?
Your business and your Gas Safe registration number, the customer and site, a specific scope, a breakdown of labour, the appliance and parts, flue and gas supply works, VAT, a timeline, payment terms, exclusions and a validity period.
How do I quote a boiler replacement?
List the removal of the old boiler, the make and model of the new boiler, the flue type and any flue works, gas supply upgrades if the pipe run needs sizing up, a power flush if required, commissioning and warranty registration, then add a variations line for anything hidden.
Should a gas engineer quote or estimate a repair?
For a defined job like a fixed boiler swap, quote it firmly. For a fault of unknown extent that needs diagnosis before parts are known, an estimate for the diagnosis with a firm quote to follow is fairer.
Do gas engineers charge VAT on a quote?
If you are VAT registered, show subtotal, 20% VAT and the total. If you are not registered, say so clearly on the quote.
