 Trustindex verifies that the original source of the review is Google. Absolutely brilliant from start to finish. Put a new boiler in a property one day after diagnosing a fault. I didn’t have to worry about one thing - no faffing, just a price given and by the next day it was complete. Armond, John and Claudia were very active throughout the process and offered me free advice to start. I’m always dubious about going with contractors you find on Google but after so many bad experiences - so refreshing for it work out like you always feel it should.

He identified the main leaking spot straightaway and had fixed it right the next day. I appreciate how knowledgeable, punctual and professional he is 🙏

 Trustindex verifies that the original source of the review is Google. My three-year-old turned the switch off at a wall behind a fish tank and he told me to check the switch. He’s a great person very needed the help.
