Can anyone tell me how big an opening I need to cut into my wall to have my new gas fire and surround fitted?
I have a chimney which is covered at the moment (the chimney has never been used, house is 10 years old) and have ordered a BE-Modern Mayfair class 1 and a 48" limestone fireplace. I want/need to do some of the prep work myself but can't get past step 1 because I don't know how big a hole to cut into the plasterboard.
Please help (any other tips for this project also gratefully received)
