Perhaps I have not remembered the background but I thought that you had only heard of this situation two weeks ago and it is for some lady.
I am left wondering why you are so concerned about a third party situation.
You talk about the cost as if you were paying for it. I am left wondering if this is in a property which you own and rent out?
If so, or even in any other situation, why are you now contemplating doing gas work for which you are not registered, for NO payment and without any insurance in case you made any mistake?
