I'm replacing a wall-mounted gas fire with a more modern version. I'm told that I need a surround to bring it away from the wall (between the living room and dining room) to give some depth to mount the fire. I'm told I need a hearth also because of building regs. I have no problem with any of this. However, I've been quoted £375 to supply a hearth (36" x 13") and back panel (36" x 36") made of marble-effect resinated stone. I don't see why it costs so much - why can't I make my own?
TIA Another Dave
