After finding his details on here, Billy and his brother have recently finished a complete re-plumb of my heating system including the installation of a new unvented cylinder and boiler in the loft. They worked very hard, including a number of hot (and no doubt unpleasant) days working in the loft during hot weather to get it done pretty much in a week -which was quick given the size of the job. I can completely agree with the comments above- Billy was excellent. He was great at communication, providing ideas and suggesting ways of doing things/ options that were cheaper at the beginning and also throughout the project giving updates etc. He was nice to have around, took care of the house and was completely trustworthy. When he came to quote you could tell that he thought about what he was doing and what the work would entail and the work came in on budget apart from one small addition which he communicated early and got approval for before going ahead and was beyond his control. Billy also went over and above what we discussed by doing nice things like including a pressure gauge and ability to increase water pressure on the ground floor as well as in the loft- means that I can top up boiler pressure as and when I bleed the radiators without having to go into the loft each time- a very nice touch. Finally he recently came back to finish the job off which was hugely appreciated. Highly recommended.
