Gas fire installation and annual servicing by Gas Safe registered engineers
Gas Fire Installation and Servicing
Gas fire installation and servicing covers fitting a new gas fire — inset, wall-mounted or freestanding — and carrying out the annual safety check and service that gas fires require, carried out only by Gas Safe registered engineers qualified in the relevant category.
Definition
What Gas Fires covers
Gas fires require correct flue or ventilation provision depending on the appliance type, and, like any gas appliance, benefit from an annual service to check for safe combustion and correct operation. Installation includes assessing the flue or chimney, connecting the gas supply, and commissioning the appliance; servicing checks the burner, flue and safety devices on an existing fire.
Suitable for
- New gas fire installation into an existing or new fireplace opening
- Annual gas fire servicing to maintain safety and warranty
- Replacing an old or inefficient gas fire
- Landlords needing a gas fire included on a gas safety certificate
Not suitable for
- Anyone other than a Gas Safe registered engineer qualified in the relevant fire category carrying out installation or service — this is a legal requirement
- Solid fuel or wood-burning stove work, which falls outside gas-specific registration
Process
How the work is carried out
- 01
Assessment
Checking the flue or chimney condition and ventilation provision for the fire type.
- 02
Installation or service
Installing the new appliance and gas connection, or carrying out the service checks on an existing fire.
- 03
Testing
Testing for gas soundness and correct combustion.
- 04
Certification
Issuing the relevant Gas Safe certificate for the work carried out.
Typical timescale
A gas fire service is typically completed within a visit; installation timescales depend on flue works needed and whether an existing fireplace opening is being reused.
Cost guidance
A gas fire service typically costs £90–£400 per job in our area, with a straightforward annual service toward the lower end and installation work, including any flue alterations, pushing costs toward the top of that range. We provide an itemised quotation after assessment rather than a fixed headline price.
Limitations and exclusions
- All gas fire work is carried out only by an engineer Gas Safe registered in the relevant fire category, in line with legal requirements
- Chimney or flue lining work beyond the fire itself, if needed, is scoped and quoted separately
- Fireplace surrounds and hearths are supplied to your specification unless a supply-and-fit package is agreed

FAQs
Gas Fires FAQs
How often does a gas fire need servicing?
Annually, the same as a boiler, both for safety and to keep any manufacturer warranty valid.
Can any Gas Safe engineer install a gas fire?
No — an engineer needs to be registered specifically in the applicable gas fire category, not just boilers. You can check an engineer's registered categories on the Gas Safe Register website or their ID card.
Do I need a working chimney or flue for a gas fire?
It depends on the fire type — some use a balanced flue through an external wall, while others are flueless and rely on room ventilation. We assess the options for your fireplace during the site visit.
