Cost Factors of Installing a Gas Fire

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

Type of Fire

There are many different types of fire, and each of them varies in cost.

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

The location of your property can affect the overall price you pay for your gas fire installation.

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.

Extra Work

You can expect to pay more in labour and materials if any extra work is needed on things such as the chimney or flue.

In most cases, an engineer will come out to inspect your current situation and will come up with a price based on exactly what is needed for your particular job.

Can 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.

Building Regulations for a Gas Fire

There are a number of different building regulations that need to be adhered to when installing a new gas fire.

The specifics of which will depend upon the type of gas fire you're having installed.

The best way to ensure you’re complying with all of the correct building regulations about your new gas fire is to ensure that you have the work carried out by a Gas Safe registered engineer.

You can also get in touch with your local council and give them a brief explanation of the work you’re having done. They should be able to advise you on the correct building regulations for your particular job.

Before you use your new gas fire, it’s essential that your Gas Safe registered engineer inspects the gas pipework, flues, and connections to ensure that it is completely safe to use.

Planning Permission for a Gas Fire

For the gas fire itself, you don’t usually need to worry about planning permission.

However, there are some rules that you need to adhere to when it comes to the flue and chimney.

Work on the flue or chimney is usually considered permitted development. This means that they don’t require planning permission as long as the flue is on the rear or side elevation, and does not exceed 1 metre above the highest part of the roof.

If your building is a listed building or in a conservation area, it is always best to check with your local council on whether or not you need planning permission for a particular job.

A Gas Safe registered engineer will be able to advise you best on whether you need planning permission. If you are unsure at any time, you should always check with your local council before having the work carried out.

  • ✔ 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, which is different from a gas safety check.

A service involves inspecting each part of the fire. The service will check for potential safety hazards which could be dangerous if not spotted quickly. Again, only a Gas Safe registered engineer can perform a gas fire service.

Servicing your gas fire regularly can save you money in the long run, as small issues can be highlighted and corrected before they become a much bigger problem. A gas fire service will also increase the lifespan of your fire.

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

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.
