To make sure that your gas fire operates both safely and efficiently, it should be serviced once a year by a Gas Safe engineer. It is also recommended that the flue is swept regularly.
This is the official body recognised by the Government to approve the installation of gas fires and gas stoves in the UK. It registers, trains and checks approved gas engineers.
If you smell gas turn off the gas supply at the gas meter (unless it's in a cellar),open all the doors and windows, call the National Gas Emergency Service on 0800 111 999.
