What the job entails

Gas fires are cheaper to run than electrical heaters and also heat up much quicker, so it's no real surprise that they are very popular! However, unlike some electrical heaters which can simply be plugged in to a wall socket, mains gas appliances need to be connected by a Gas Safe registered engineer for important safety and legal reasons. Connecting up a gas fire may seem relatively simple, but unless you are Gas Safe registered, it is also illegal (and possibly dangerous). So when buying a gas fire which needs a mains gas supply, you should remember to factor in the installation costs to your budget. It's also important to note that many retailers will offer an installation service, but this often not the cheapest option, though may be the easiest, you have to decide what is more important to you. To help with these decisions, we have provided some typical prices for your information.

While you have a gas safe engineer on-site anyway, it may be worth asking them to carry out any checks or regular maintenance at the same time, as there could well be a small discount offered for saving them having to call-out to the property again. If having an old gas fire removed, be aware that you may need to redecorate afterwards if the fire or the surround was fixed to the wall. A plasterer may also be required if the plasterwork is damaged during the removal. Remember also that not all gas fires are suitable for all types of flue or chimney, if you choose a gas fire which is not suitable for the existing flue/chimney, you may need to have the chimney lined and tested.

You don't necessarily need to have a chimney to have a gas fire, there are currently three types of gas fire that do not need a chimney or flue. Flueless gas fires are designed to work without any sort of flue and often use catalytic converters to change the gas combustion products into harmless vapour which can be safely vented into the room. Balanced flue gas fires evacuate the combustion products and allow in air for combustion through the wall behind the fire. These fires are completely sealed from the room and usually have a glass front through which you can see the flame. Power flue gas fires use a fan to move the combustion gases to the outside world and are often used where a conventional chimney or flue is too small. You should check with your gas safe engineer to determine the flue and ventilation requirements.

Trying to fit a gas fire or other appliance yourself, or getting an unqualified handyman to do it, is not only dangerous, it could end up increasing the cost of the job when you have to get a gas safe engineer in to fix your bodge job, then do it properly.

FAQ's

Yes, a fire guard is recommended for all types of open fires for the protection of children and pets.
The type of chimney or flue is sometimes hard to identify, so it is always worth asking for a survey if you are unsure. Homes built before the late 1960 usually have Class 1 chimneys, later homes may still have Class 1 chimneys but with Class 2 flues or even pre-cast flues - it can all get a bit confusing and you need to certain which type of chimney or flue you have before choosing a new gas fire. That being said, there are types of gas fires which are suitable for installation with all types of chimney and flue - but you still need to ensure the flue is clear and safe to use.
This depends on its condition and you ned to check with the installer or your chimney sweep for further advice. A simple test to be carried out to check if everything is okay with the chimney for peace of mind. Never assume that a chimney or flue works correctly simply because it is open. Also if the chimney does need lining, this could restrict your choice of gas fire.
Not all of them, but some do. Gas fires with a manual control and piezo spark ignition do not usually require mains power supply to operate. So you only need a Gas Safe registered engineer to install and not a qualified electrician, which is obviously cheaper. Some gas fires will offer remote control which will require a battery but still do not require a mains supply.
Most flued gas fires do not require additional purpose ventilation, but all flueless gas fires installed in the UK require additional purpose provided ventilation. The gas safe engineer doing the installation will be able to offer advice on exactly what is required and will ensure adequate ventilation before issuing a certificate. It is strongly recommended that the air vent, if required, is fitted by the same Gas Safe engineer who is fitting your gas fire. Failure to fit the air vent in accordance with the manufacturers instructions, can nullify any warranty.
