Hi, my builder has given me a price to supply and fit double glazed door and window on a small porch he has built for me (he has been dealing with the council with regards to building regs).
I don't believe he is FENSA registered (according to their website), and I believe that the council will require some installation certification. Does this mean he has to be FENSA approved to fit it? Should I get someone that is to sort it out instead?
