Alan and the team removed our dual heating/water system and replaced with new efficient combi plus Hive. Work was completed on schedule, lots of helpful communication about what services would be off and when. Consulted with me at all major decision points. I had to leave them to work for a day without being there, and when I got home, you wouldn’t have known anyone had been in, left the rooms clean, tidy etc. Took utmost care to reuse existing holes in brick work and not to disturb expensive bathroom flooring. Wouldn’t hesitate to call them again.
