10 Fast, Reliable and Professional Service
Posted 23 March
Job location: HP2I had a great experience with this company. Communication was quick and clear from the start, and they were able to arrange a date very quickly given the urgency of my situation. The installation of my new boiler was completed within the expected timeframe and everything was done efficiently and professionally. The team was reliable, respectful, and made a stressful situation much easier to manage. I would definitely recommend their services.10 New Bathroom installation and Underfloor Heating in separate rooms

Posted 24 April 2025
Excellent service from start to finish. Initially Jarek assessed the old boiler to see if the problem could be fixed, clearly explaining the issue with the old boiler and outlining the costs involved in replacing the parts that were faulty. He then recommended the best replacement options which fit our needs (not only was the old boiler beyond repair but also far smaller than our requirements) and at our request sourced the best options for a very good price! Carried out all the works quickly, efficiently and very respectfully and showed us how to use it. Tidied up excellently afterwards.Verified reviewerJob location: SL010 Our boiler had stopped working and needed to be fixed

10 Investigation of drain pipe susceptible to blocking
Posted 28 March 2025
Jarek responded promptly to my request and arrived at the agreed time. I was very happy to get such a quick response. He investigated flow through the drainpipe from flat roof down to the street, concluded that problem was not to do with flow but due to ingress of leaves causing a blockage. He returned with a screen, which he fitted and recommended that occasional leaf removal should be instituted. He was very clear with communication and straightforward to deal with.Verified reviewerJob location: W4
