I've been told that the siting of my tank does not comply with the law, what do I do ?

There is no law which specifies where tanks should be sited but there is a lot of gudiance in our Codes of Practice and in Approved Document J which supports the Building Regulations. If you are concerned talk to your LPG supplier. If you are thinking of changing suppliers remember that individual companies may have different ways of doing things but they will all have safety as a first priority.
