Hi, we are currently using Oil but will be having a Gas supply laid from the road to a new meter on the front wall of the house. Does the meter have to be installed by a Gas Safe engineer? Do I have to have a contract with a gas supplier before it is installed? What are the regulations for the supply pipe from the meter round the side and round the back of the house? I was thinking about it being at ground level to go under the back door step. Thanks.
