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 around £650.
  • 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 style you choose, a new hearth installation costs between £100 and £350.
  • Ventilation requirements - To comply with Building Regulations Part J (covering ventilation and flue safety), you'll need air vents installed, costing around £100 to £300.

If You're Upgrading Your Existing Gas Fire

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 £20 to £60 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. Fireplace surrounds vary widely in price depending on the material and design you choose.

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 £250 and £450.

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 £300 and £600.

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 converts heat around the room efficiently.

  • ✔ 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 £400 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 £450 and £1,000.

Flueless fires are designed for people who don’t have a fireplace or chimney in their home. It is a clean-burning device which has a catalytic converter built right into it. The catalytic converter cleans the air that passes through it, and removes any harmful emissions before safely releasing it into the air.

flueless gas fire cost

Pros

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

Cons

  • ✖ Relies on the catalytic converter to release safe air
  • ✖ Permanent ventilation needed which can cause draughts

Balanced Flue Gas Fire Cost

Balanced flue gas fires cost between £700 and £1,500.

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 £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 £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? Any work on a gas appliance in the UK must be carried out by an engineer listed on the Gas Safe Register.
  • 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.

FAQs

How much does it cost to run a real flame gas fire?

A real flame gas fire typically costs around 5p per kWh to run.

Do you need a guard for an open gas fire?

Yes, a fire guard is highly recommended for any open fires to protect your children and pets.

Do gas fires require an electricity supply?

Not all gas fires require an electricity supply, but some will have a remote control which requires batteries to operate, but it won’t require a mains supply.

Is a gas fire cheaper to run than an electric fire?

Gas fires are typically cheaper to run than electric fires, as gas is typically the lower-cost fuel option. A gas fire installed in an average-sized room can provide more warmth for less money over the years. That said, electric fires have lower installation costs, so your overall budget will determine which is the better choice for your home.

Can I replace a wood burner with a gas fire?

Replacing a wood burner or stove with a gas fire installation is straightforward in most cases, as both appliances use an existing chimney flue. A heating engineer will assess your traditional chimney to confirm it is compatible and installed safely with the new fire. If your existing chimney requires any attention, this will add to the overall costs involved.

Do I need building regulations approval for a gas fire installation?

The specifics depend on the type of fire being installed. An engineer listed on the Gas Safe Register can self-certify compliance and provide a Building Regulations Compliance Certificate on completion. Before use, they should also inspect the pipework, flues, and connections to confirm everything is safe.

Do I need planning permission for a gas fire installation?

For the gas fire itself, planning permission is not usually required. Work on the flue or chimney is generally considered permitted development, provided the flue sits on the rear or side elevation and does not exceed 1 metre above the highest part of the roof. If your property is a listed building or in a conservation area, check with your local council before having the work carried out.

Can I install a gas fire myself?

No, gas fire installation should only be carried out by Gas Safe registered engineers. This is a legal UK requirement, and no one else should attempt installation.
