Extra potential costs for your gas fire installation
Want to budget for extra potential costs involved in your gas fire installation? Smart move.
Here are some other costs to be aware of on top of the price of buying and installing your gas fire:
Removing existing gas fire
Don’t forget to factor in the cost of removing your old gas fire. The ballpark figure to remove an existing gas fire is around £75.
You can learn more about the costs involved in our gas fire removal cost guide.
Repairs to existing components
If you have an existing chimney or flue, some maintenance work may need to be done before your new gas fire is up and running. This is to ensure the fire is working both efficiently and safely.
You may need to budget for additional costs if:
- A new support or surround is required for the gas fire to be installed
- Repairs to the chimney or flue are required
- Plastering or decoration is needed after replacing an existing gas fire
Carbon monoxide sensors
Are you installing a gas fire for the first time? Ask your gas fire installer to fit a carbon monoxide sensor in the same room as the gas fire to keep your home safe.
This clever device measures the concentration of carbon monoxide gases in the air and sounds an alarm if it detects any harmful gases.
The device costs between £10 – £20 – a small price to pay to keep you and your loved ones safe.
Annual servicing
An annual service keeps your gas fire ticking along efficiently and safely.
The average cost is around £85.
You can explore the maintenance costs in our gas fire service cost guide.
Top tip – Get ahead by pre-booking your fire’s first annual service during the installation. If you can time it before using the gas fire in the colder months, that would be even better!
Who can install a gas fire?
Only Gas Safe registered engineers can install gas fires.
Checking if your gas fire installer is registered is simple. Just ask for a copy of their Gas Safe ID card.
Top tip: Some disreputable tradespeople falsely claim they are Gas Safe registered by using the logo on their website, vehicle, or business card.
However, the only way to be sure they are qualified to work in your home is to ask for their Gas Safe ID card.
Did you know you can also check if your gas fireplace installer works legally? Simply check the tradesperson’s qualifications with our Checkatrade directory.
You’ll only find trades on Checkatrade that pass our strict checks – and have our trusted tick of approval.
There’s plenty more information about how to tell if your gas engineer is working legally in our guide.

Does a gas fire need to be registered?
After the installation, you can ask your gas engineer to complete a Gas Safety Report.
If your gas fire is under warranty, this report is often required for the warranty conditions. You’ll also need to make sure your gas fire is serviced every 12 months to keep the warranty valid.
It’s worth noting that it’s not a legal requirement for your gas engineer to provide a Gas Safety Report. So, you’ll have to remember to request it.
There’s one exception to this – if you’re a landlord. You can find out more about the costs involved in gas safety certificates for landlords in our cost guide.

Your gas fire glossary
Feeling confused about the types of gas fires available and the variety of components to consider. You’re not alone!
We’ve listed below some of the main terms used when referring to gas fires. That way, you can be clear about what you’re investing in when speaking to your gas fire installer.
Types of gas fires:
Open-fronted gas fire: This traditional-style gas fire features an open-front design, allowing the flames to be visible without a glass barrier.
Glass-fronted gas fire: This style features a glass panel at the front, which encloses the flames for increased efficiency and safety.
Flueless/ventless gas fire: These fires, which are becoming increasingly popular in new homes without chimneys, don’t require a venting system or flue. This means they can be placed almost anywhere in the home.
Outset gas fire: This style of gas fire protrudes from the wall or fireplace and provides a standout feature in a room.
Gas wall heater: A low-cost way of heating a small room without needing a full central heating system, flue or chimney.
Gas fire components:
Fireplace inserts: This is the gas fire’s source of heat. Inserts are slotted into the fireplace and are powered by gas.
Framing and flashing: Framing holds the insert in place, whilst flashing refers to pieces of metal that attach the insert to the framing.
Hearth: The base of your fireplace protects the room floor from heat. Although they are not essential for gas fires, they are often installed for aesthetic reasons.
Surround and mantel: The aesthetic fixture surrounding the gas fire. Typically made from wood, marble, stone, cast iron or brick.
Chimney, flue, or vent: These are used to release gases safely. They are not essential for flueless and ventless gas fires, but other gas fires will have one. A flue is typically fitted through an exterior wall, and a vent is typically fitted through a wall or roof.

FAQs
Can a gas fire be fitted without a chimney?
Yes, a gas fire can be fitted without a traditional chimney. You’ll be looking to install a ventless gas fire.
These fires don’t need a chimney, venting system or flue, so they can be placed almost anywhere in the home. A professional Gas Safe registered engineer can advise if a ventless gas fire is right for your home.
Our cost guide also contains lots more information about ventless gas fires and their prices.
Can I install a gas fire myself?
No. You should never try to install or remove a gas fire yourself. Only a gas-certified installer should attempt this job.
How long does it take to install a gas fire?
- A new gas fire installation in an existing fireplace will take approximately three to six hours
- Vent-free gas fires are typically quicker to install as you don’t require a chimney, vent or flue. So, you’ll be looking at approximately two to four hours
- If you’re installing a gas fire without an existing gas fireplace, you’ll be looking at approximately one to two days
Is it worth installing a gas fire?
Absolutely. When installed safely by a Gas Safe registered engineer, a modern gas fire can be an efficient and cost-effective heat source for a room.
They are also far less messy than a real fire or wood burner, as you won’t need to worry about regular hearth cleaning and buying logs.
Is it cheaper to run a gas fire than radiators?
Gas fires can be expensive to run if they’re the sole source of heat in the home.
Radiators connected to a central heating system might be a better option. They will consistently and efficiently heat an entire home, especially in larger houses. However, the cost of installing a central heating system can, of course, be expensive if you’re starting from scratch.
Which is cheaper, gas fire or central heating?
As mentioned above, if gas fires are your sole source of heat in the home, it will be costly to run in the winter months.
You can explore the costs more in our gas vs electric heat cost guide.
How much does it cost to run a gas fire for one hour?
That’s hard to say. After all, it all depends on how efficiently your gas fire is running – and, of course, your current gas price.
To give you a rough estimate, a gas fire consumes about five kilowatts (kWh) of energy per hour. With the current average gas prices, running a gas fire for one hour could cost between 50 – 70 pence per hour.
Is it illegal to fit a second-hand gas fire?
While buying a second-hand gas fire may be tempting to cut costs, we wouldn’t recommend it. In fact, most Gas Safe registered engineers will refuse to fit a second-hand gas fire.
On Checkatrade, you'll only find trades who meet our high standards and pass up to 12 checks.
