HIU inspection

Risa T. from Ealing, West London – W5. ( 11th of September )
Justin carefully went through my HIU system with a fine-toothed comb and figured out exactly what the issue was. He tested everything and was very thorough and meticulous in his work. The report he wrote up was very detailed and useful. He gave an honest assessment of what needed to be done to solve the problem and what was recommended for optimal health in the long term. He showed up on time, which was great, and even came back the next day to check things were working.

Superb service.

W.M from Wandsworth, South West London – SW18. ( 2nd of September )
Prompt, professional, transparent and knowledgeable expertise. Regular and clear communication throughout.

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!

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.

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.
