Ben replaced our hot air heating system with radiators and our old boiler with a new combo boiler He impressed from his first visit with his knowledge and advice It was a really big job but he managed to compete in 4 days Despite the amount of work, Ben left the house tidy at the end of each day and even provided us with fan heaters to keep us warm for the few days where we were without heating With a 1 year old daughter, to do all the work so quickly and tidily was much appreciated.
