 Trustindex verifies that the original source of the review is Google. Fitted boiler for a great price. All work carried out quickly, efficiently and left tidy when complete. Had problems with gas pressure for which he arranged an engineer call out and made sure everything was working as it should be before he left. Really couldn't want a better service Thanks 👍

 Trustindex verifies that the original source of the review is Google. A great service after a rogue power surge blew out most of the boilers in the street. Dan nursed all the residents boilers back to 100% and better no matter what the hour. Efficient, good humoured and very reassuring. The TOP man to deal with a crisis.
