Wow, stop the presses, trade body tells porkies to get people to use it's members. It is a lie, if you read the gas safety regulations you'll see that it's a lie.Just got my certificate through from Gas Safe / Building Compliance. Part of it says " It is a legal requirement for anyone carrying out any gas work on your behalf to be Gas Safe Registered."
But then, "It is mostly a legal requirement for anyone carrying out any gas work on your behalf to be Gas Safe Registered." doesn't carry the same gravitas.
