How Much to Fit a Gas Fire?

On average, the total cost to fit a gas fire is £850, with most installations falling between £500 and £1,500, although balanced flues can exceed this range. This includes labour and supply costs.

However, your exact gas fire installation cost will depend on the following:

• The type of gas fire (inset, outset, flueless).
• The complexity of the installation (whether extra pipework is needed).
• Your location in the UK (London and the south being more expensive than other areas).

Additional Gas Fire Installation Costs

Depending on your situation, you'll encounter different additional costs when fitting your new gas fire. Here's what to expect:

If You're Installing a Gas Fire for the First Time

Installing a gas fire for the first time in your property is likely to incur more additional costs than if you were doing an upgrade. You may need to budget for:

• Cost of Installing a Gas Supply — If you need to connect to a gas supply for the first time, this will cost between £2,000 and £4,000.
• Chimney and Flue Work — If your chimney needs repairing, a chimney liner cost will be around £800, depending on your chimney's height.
• Fitting a Hearth — Depending on the material you choose, a new hearth costs between £300 and £600 supplied and fitted, with slate at the lower end and limestone or marble at the top.
• Ventilation Requirements — Whether you need an air vent depends on the type of fire, its heat output, and how well-sealed your home is. A flueless fire always needs ventilation, but a decorative fuel-effect fire rated at 7kW or less often needs none in an older, less draught-proof home. A newer, well-sealed property will usually require a vent. Where a vent is needed, budget around £100 to £300.

If You're Upgrading Your Existing Gas Fire

If you're replacing a gas fire like-for-like into an existing, ready-prepared opening, labour alone typically costs around £125 to £220. Including a new fire, a typical straight swap costs around £475 to £1,270 in total.

Swapping an old gas fire for a new one is relatively simple compared to a first-time installation, but you'll still be faced with a few additional costs:

• Cost of Removing Old Gas Fire — This typically costs between £180 and £250 depending on the type of gas fire.
• Capping or Adjusting Old Pipework — If you need your gas supply changing, expect to pay between £80 and £150.
• New Chimney Liner (if Required) — Chimney liners cost around £800, and are needed if your existing liner doesn't meet modern safety standards.
• Waste Removal — Additional charges of around £50 to £150 can be expected to dispose of your old gas fire.

Factors That Impact Gas Fire Installation Costs

There are several things that can affect the overall cost of a gas fire installation:

• Type of Fire — The price you pay for the fire itself can depend on the kind of fire you choose, the manufacturer, and the variety that you choose. As with any home appliance, you can get some fires with extra features or better materials that will cost more.
• Location of Property — Those located in London can expect to pay around 30% to 50% more for labour than those located in the north or other parts of the UK.
• Size of Fire — The larger your fire, the longer it is going to take to install. Therefore, you should expect higher labour costs.
• Your Existing Chimney or Flue — Labour and materials costs increase if any extra jobs are required on your existing chimney or flue. If you don't have a traditional chimney, the type of fire you choose will also affect the overall cost, as a balanced flue or flueless fire may be the only option.
• Fireplace Surround and Hearth — The style of fireplace surround and hearth you choose alongside your fire will add to the overall cost. A surround typically costs around £525 to £1,500 to buy, with timber and limestone at the lower end and marble at the top. A new hearth costs around £300 to £600 supplied and fitted.

Choosing a Gas Fire

There are a number of different types of gas fires. Below is a list of the different types of gas fire that you can get, along with their prices:

Open Front Gas Fire Cost

Open front inset gas fires cost between £350 and £1,050.

This type of fire comes with several controls and different decorative options, meaning you can choose a style that suits you.

Pros

• ✔ Aesthetically pleasing
• ✔ Lots of control options

Cons

• ✖ Less efficient than other gas fire models.
• ✖ Heat can escape through the chimney.

Outset Living Flame Gas Fire Cost

Outset living flame gas fires cost between £480 and £1,050.

Living flame fires protrude out of the wall and sit on the hearth. This type of fire usually gives off a lot of heat because the body of the fire heats up, and this circulates heat around the room efficiently.

Pros

• ✔ Gives off a lot of heat.
• ✔ Has large controls that are easy to use.

Cons

• ✖ Takes up a lot of room.
• ✖ Can be considered outdated.

Glass-Fronted High-Efficiency Gas Fire Cost

Glass-fronted high-efficiency gas fires cost between £470 and £1,500.

Glass-fronted high-efficiency fires tend to have an efficiency rating of around 80% to 90%. They use technology to increase the energy efficiency above the efficiency of a regular gas fire.

Pros

• ✔ Highly efficient
• ✔ Modern design

Cons

• ✖ May not give off as much heat as traditional gas fires.
• ✖ More expensive than other gas fire options.

Flueless Gas Fire Cost

Flueless gas fires cost between £470 and £1,550.

Flueless fires are designed for people who don't have a fireplace or chimney. A catalytic converter built into the fire reduces carbon monoxide to a safe level, but unlike a flued fire, the products of combustion are released into the room rather than up a chimney. This is why flueless fires need permanent ventilation, and why the room needs to be a suitable size for the fire you choose.

Pros

• ✔ Doesn't require a chimney
• ✔ Highly efficient

Cons

• ✖ Combustion products go into the room, not up a chimney.
• ✖ Permanent ventilation needed which can cause draughts.

Balanced Flue Gas Fire Cost

Balanced flue gas fires cost between £1,050 and £1,950.

This type of fire is designed for people who want all the benefits of a gas fire but don't have a fireplace, flue, or chimney built into their home. It comes with its own flue that leads directly through an external wall.

Pros

• ✔ Allows you to have a fire without a chimney
• ✔ Very efficient

Cons

• ✖ Can be difficult to install in some cases.
• ✖ Needs to be on an external wall.

Gas Fire Maintenance Cost

A gas fire requires an annual gas safety check, designed to ensure the fire works efficiently.

A Gas Safe registered engineer will carry out the check, ensuring the correct pressure, supply, and safety, and will also check the flues and chimney to ensure everything is working correctly.

Your gas fire will also need to be serviced regularly by a registered engineer, which is different from a gas safety check.

A gas fire service costs around £95, and will take around 1 to 2 hours.

A service involves inspecting each part of the fire to check for potential safety hazards that could be dangerous and costly if not spotted quickly, saving you money in the long run and extending the lifespan of your fire.

Gas Fire Removal Cost

In some cases, you may want to remove an old gas fire to make way for a new one. Or perhaps you want to remove a fire to create more space in the room.

If that's the case, the gas elements of your fire should be removed by a Gas Safe registered engineer as they can safely remove your fire correctly, typically costing between £180 and £250.

Checklist: Hiring a Gas Safe Registered Engineer to Install Your Gas Fire

There are a few things you will need to consider before hiring someone to install a new gas fire for you:

• Are they listed on the Gas Safe Register? Anyone you employ to work on a gas appliance must be listed on the Gas Safe Register and competent for that type of gas work.
• Are they a member of a recognised trade body? The Association of Plumbing and Heating Contractors (APHC) and the Chartered Institute of Plumbing and Heating Engineering (CIPHE) are both recognised bodies for heating professionals.
• Do they have insurance? Public liability insurance protects you if something goes wrong during installation.
• Will they provide an itemised quote? Ask for a breakdown of costs, so you know what is included and whether there are any hidden fees.
• Do they offer a guarantee? Ask about any warranties on parts and labour, so you know where you stand if an issue arises after the job is done.
• Do they have examples of previous work? Ask to see photos of past installations, or check their MyJobQuote profile for examples of similar jobs.
• Do they have positive reviews? Read feedback from previous customers on their MyJobQuote profile.
