10 Combi boiler replacement installation with Hive Smart Control.
Posted 20 April
Very pleased with work carried out to a high standard and well ahead of schedule! Very clean and tidy as well as punctual.Verified reviewerJob location: TW1410 Multiple Radiator replacement and relocation
Posted 13 April
Will certainly be using again! At extremely short notice Marc was able to move and re-plumb multiple radiators after an urgent request was made in order to get the rooms ready in our new house before we had new flooring laid. Polite, honest, reliable and very reasonable are words I would use to describe the service we received. Marc’s genuine knowledge and passion for his profession shone through and also his kindness and care to go above and beyond (taking the time to explain how to use our new heating system in detail to help out is one example). I would highly recommend. Thank you so much!Verified reviewerJob location: TW210 Gas boiler and thermostat not working
Posted 14 February
I booked in for an engineer to visit he arrive as agreed. Marc identified the problem and immediately sourced the part, went to the shop and came back and fitted it. The boiler was working. As agreed he came back the following week and installed the new thermostat. I would have no hesitation using them again.Verified reviewerJob location: TW810 Boiler maintenance, Boiler Repairs, Bathroom replacement. Kitchen tap replacement.

Totally reliable, very honest about costs and transparent about material costs. Highly recommended and have done to all my family, friends & neighbors. Nothing is too much trouble and refreshingly honest recommendations about repair or replacement.Verified reviewerJob location: TW310 Annual boiler service

The company gave me good advice on what they would do and gave me a cost of a callout. The Heating engineer was very pleasant and professional. He gave very good advice. He increased pressure on the boiler as it was low. He also talked me through how to use the thermostat and how to set it up.Verified reviewerJob location: UB3
