What changes the cost of installing a gas cooker?
The cost of installing a gas cooker depends on whether it is a straight swap or a new position, whether the gas pipe needs extending, whether it also needs an electrical connection, and who removes the old cooker. The connection must be made by a Gas Safe registered engineer, and this guide does not print a price.
Last reviewed:What does installing a gas cooker involve?
A new gas cooker might be a straight swap for an old one, part of a kitchen refit, or a change from electric to gas. QuoteZila starts in Cheshire, with Crewe, Nantwich and Sandbach first, and anyone in the UK can post a job or register. This guide explains what a gas cooker installation involves and what makes one quote higher than another.
For a typical freestanding gas cooker, the engineer checks the gas supply point, connects the cooker with the right hose or fittings, tests the connection for leaks, checks the burners, grill and oven light and burn properly, and makes sure the cooker is stable in its space. For a built-in gas oven and a separate hob, there is more fitting into units and worktops.
This guide does not print a price. The cost depends on the cooker, your kitchen and the engineer, and a figure without that context would mislead.
Who is allowed to do it?
HSE says anyone employed to work on gas appliances in domestic premises must be a Gas Safe registered engineer and competent in that area of gas work [S1]. It says the engineer's competencies are clearly marked on the back of their Gas Safe Register ID card, and that you can check with Gas Safe Register if in doubt [S1].
Many freestanding cookers connect with a bayonet fitting, a push-in point on the wall with a flexible hose. HSE says these cookers are not considered readily movable, but can be moved temporarily, for example to clean the space they normally occupy, and that this is not regarded as gas work [S2]. It says any other type of installation or reinstallation is gas work and must be carried out by a Gas Safe registered engineer [S2]. So pulling a cooker out to clean behind it is fine. Connecting a new one is not a DIY job, even onto an existing bayonet.
This guide gives no steps for gas work. Check any engineer on the Gas Safe Register before work starts.

GOV.UK names Gas Safe Register as the competent person scheme for installing gas appliances [S3].
What changes the cost?
| Factor | What to ask | Why it moves the price |
|---|---|---|
| Type of cooker | Freestanding, range, or built-in oven and hob | Built-in work means fitting into units and worktops |
| Fuel | All gas, or dual fuel with an electric oven | Dual fuel also needs a suitable electrical supply |
| Supply point | Is there an existing gas point where the cooker will go? | A straight swap is the simplest job |
| New position | How far the pipe must be extended, and its route | Lifting floors or opening walls takes time |
| Connection | Bayonet hose, fixed connection, or a new point | HSE treats installation and reinstallation as gas work [S2] |
| Stability | Whether the instructions call for a stability bracket or chain | A fitting step some quotes leave out |
| Electrical work | Socket, spur or new circuit for ignition or an electric oven | A separate trade if the gas engineer does not do it [S3] |
| Old cooker | Who takes it out and disposes of it | Waste and time |
| Hood and extraction | Whether a new cooker hood is being fitted at the same time | Separate job, often booked together |
| VAT | Included or extra. Registration applies above £90,000 of taxable turnover [S5] | Changes the total |
The two biggest swings are the gas supply and the electrics. A like-for-like swap in the same place is the shortest visit. A new position, or a change from an electric cooker to gas, can mean new pipework.
Freestanding, range or built-in?
Freestanding cookers slide into a gap between units and usually connect to a bayonet point. If the gap and the point already exist, this is usually the most straightforward job.
Range cookers are wider and heavier, and some have more than one oven. Check the gap, the position of the gas point and any electrical needs before you buy. Ask whether the engineer needs a second person to move it into place.
Built-in ovens and separate hobs fit into units and the worktop. A gas hob needs a cut-out, and an oven needs a housing. Kitchen fitters often do that part, and the gas engineer connects the gas. Gas hob installation explains the hob side in more detail. If the oven is electric, see electric cooker installation costs.
What if the cooker is moving to a new position?
Moving a cooker to another wall, or into an island, means the gas pipe has to go there too. That is gas work for a Gas Safe engineer. Ask:
- where the new pipe will run, under the floor, in the wall or along the units
- what has to be lifted, opened or boxed in to get it there
- how the pipe will be tested once it is in place
- who makes good the floor, plaster or tiles afterwards
If the move is part of a kitchen refit, plan the gas run before the floor and the units go in. Kitchen costs explains what moves the price of the wider job. If your gas meter is in the way of the new layout, moving a gas meter covers that separate job.
What about the electrics?
Many gas cookers need electricity for ignition, a clock, an oven light or a fan. A dual fuel cooker, with a gas hob and an electric oven, needs a supply suited to the oven. Check the maker's instructions for what your model needs.
GOV.UK lists the installation of a new circuit connected to the fuse box among work you must tell a building control body about, unless you use an installer registered with a competent person scheme [S3]. It lists electrical installation work in association with kitchen installations among the jobs competent person schemes cover [S3]. Use a registered electrician for any new circuit, and see our electricians page. This guide gives no steps for electrical work.
Safety after the cooker is in
HSE strongly advises that all gas appliances, flues and pipework should be installed, regularly maintained and serviced at least annually by a Gas Safe registered engineer [S1]. It says it is illegal for anyone to use a gas appliance if they suspect it is unsafe, and to turn it off until a registered engineer has checked it [S1].
If you think you can smell gas, HSE says to call the National Grid gas emergency number on 0800 111 999, open all the doors and windows, and shut off the gas supply at the meter control valve if you know where it is [S1].
If you rent the home out, HSE says landlords must make sure an annual gas safety check is carried out within 12 months of installing a new appliance or flue they provide, and annually after that [S2]. It says the record must be kept for 2 years, with a copy given to each existing tenant within 28 days and to new tenants before they move in [S2]. If you are a tenant who has provided your own cooker, HSE says you are responsible for arranging its maintenance by a Gas Safe registered engineer [S2].
How do you compare quotes?
Ask each engineer to quote for the same scope: which cooker, where it goes, what kind of connection, whether the pipe needs extending, whether a stability bracket is fitted, who handles the electrics, and who takes the old cooker away. Send the model number and a photo of the space and the gas point.
Citizens Advice suggests trying to get written quotes from at least 3 different traders [S4]. It says a quote is a fixed price, while an estimate is just a rough guess, so you might end up paying more [S4]. It says to be cautious if one price is a lot lower than the others, because they might not be quoting for exactly the same work [S4].
Our heating engineers and kitchen fitters pages cover gas appliance work and kitchen fitting.
Jobs you might post
These are examples, not taken from real job posts.
- "Replace a freestanding gas cooker with a new one of the same width, on the existing bayonet point. Please take the old one away."
- "New dual fuel range cooker. Gas point is in place, but we need to know if the electrics are suitable. Please quote with an electrician if needed."
- "Kitchen refit moving the cooker to the opposite wall. Need the gas pipe extending before the new floor goes down."

Questions about gas cooker installation costs
How much does it cost to install a gas cooker?
This guide does not print a figure. A like-for-like swap onto an existing bayonet point is a different job from moving the cooker to a new wall, and both are different from a built-in oven and hob. Ask each engineer to price the same scope in writing.
Can I connect a gas cooker myself if it has a bayonet fitting?
No. HSE says freestanding cookers on a bayonet fitting can be moved temporarily, for example to clean the space they normally occupy, and that this is not regarded as gas work. It says any other type of installation or reinstallation is gas work and must be done by a Gas Safe registered engineer.
Who is allowed to install a gas cooker?
HSE says anyone employed to work on gas appliances in domestic premises must be a Gas Safe registered engineer and competent in that area of gas work, and that the competencies are on the back of the engineer's ID card. Check the card covers cookers.
Does a dual fuel cooker need an electrician too?
It may. A dual fuel cooker has a gas hob and an electric oven, so it needs a suitable electrical supply as well as the gas connection. Check the maker's instructions for what it needs, and ask whether a new circuit is involved before the gas engineer arrives.
What do landlords need to do after a new gas cooker goes in?
HSE says landlords must make sure an annual gas safety check is carried out within 12 months of installing a new appliance they provide, and annually after that, by a Gas Safe registered engineer. It says the record must be kept for 2 years and a copy given to existing tenants within 28 days.
Is a carbon monoxide alarm needed in a kitchen with a gas cooker?
HSE says that in England, relevant landlords must provide a carbon monoxide alarm in any room used as living accommodation that contains a fixed combustion appliance, excluding gas cookers. For homeowners, HSE strongly recommends CO alarms as one useful precaution, not as a replacement for maintenance.
Does VAT change the price?
It can. A business must register for VAT if its taxable turnover for the last 12 months goes over £90,000. Ask whether VAT is included in the quote.
Does QuoteZila check gas engineers?
No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.
This page is general information, not professional or legal advice. QuoteZila does not check Gas Safe, WaterSafe, NFRC, NICEIC or other registrations against the register on your behalf: look them up yourself.
