New combi boiler fitted and old one removed along with the water tanks and cylinder. Dylan, Andrew, James and Jordy made a very hard job look easy, that was easily 2 days work squeezed into one. They didn’t leave any mess behind either, everything was well cleaned up before they left. Thanks lads great job”
Thanks Lads
Great Job- Gerard O’Connor – February 2025
I wish I had of upgraded sooner to this combi heating system. I found a massive difference in my power shower and instant water with portable digital controller. The guys were terrific, clean and tidy and exceptionally professional. Such a brilliant job carried out with precision and perfection. Quote the same day with options and installation a week later. Powerful job and I highly recommend this company.”
