I had a fire place wanted to replace it with new mantel, hearth and gas fire etc so bought the bits from B&Q. I've really struggled to get a plumber / heating engineer to do the job, ended up finding a guy who fits fires but he quoted me £350 to fit new hearth, mantel and fireplace says about hrs work says not many people do it, I have struggled to find someone, is it really that much of a small market ? Thinking I might have a career change now
