After a little advice chaps. We are replacing out original gas fire with a high efficiency hole in the wall number. The existing fireplace is 600mm wide but we have as much height as we need, the problem I’m having is finding fires of certain dimentions, has anybody else found a www that has the option to search based upon widths? Was contemplating widening it but that looks like it’ll be a headache. Also if anyone got any recommendations of gas fitters/builders in Aberdeen then please share. Thanks!
