“Matt installed an ATAG economiser combo boiler to replace our old tank system. From providing a quote, to completion of the job, he provided a fast, reliable and friendly service. Work was finished in the timescale given, and very clean tidy job throughout. Mat even dealt with a leaking hot water pie which was badly installed in our (relatively) new kitchen. Would highly recommend both Mat and the ATAG boiler to anyone looking for a replacement.”

“Mat completed an excellent job of replacing old pipework, radiators and boiler at my elderly Father's house. I cannot fault the service in any way with Mat going the extra mile to ensure the least amount of disruption was caused to my Father. He kept me informed every step of the way and completed a fantastic job. I would not hesitate to recommend Mat if you want a trustworthy, reliable and professional tradesman to complete the work required. Thank you Mat.”
