Great service.
Kieran Wang
Punctual, knowledgeable at a fair price. Recommend!
Extremely good and thorough HIU service. Our technician Justin was very helpful in identifying a radiator issue and give us solutions to fix it. He also explain all the aspects of maintaining HIU functioning in our home. Best service we ever experienced!
Chloe Selby
I really appreciated Justin's thorough work, explanation and professionalism. We have had repeated challenges with the HIU in our property, and it has been hard to find a professional we can trust. Following the visit and repair, I now understand the problem in more detail, why and how it happens, and who to call if it happens again. Justin arrived when he said he would, fixed the problem on site and charged a very reasonable price for his work. I highly recommend.

Very professional, easy to book and on time! Just sent an email and the next day I had someone to check the boiler. Paying is also easy, as you can choose credit card and also Google Pay accepted.

I contacted Add detail for a leaking HIU, I used the online booking service allowing you you to book time, date & send photos, the request was followed up the same day with an email allowing to add more details & confirmation of booking. The engineer arrived exactly at the time stated, they were very polite and professional & explained everything what he was doing. I am very pleased with the service provided & will be recommending them to my neighbours for annual servicing & maintenance.
They were very professional and came out the same day to sort out my heating system. Excellent service.
