Justin from Add Detail attended to my flat to install new smart thermostats for my underfloor heating and to help me map the manifold actuators with correct areas of the flat, and also checked my HIU. Justin patiently explained everything. Previously I had horror experiences with a large contractor imposed on us by our building's freeholder/ their managing agent, so I am so glad I have found Justin. Also very fair pricing per hour. Have recommended Add Detail HIU to neighbours in our building needing help as well.

Exceptional company to deal with. Great communication, always responsive and carried out excellent work on an HIU including service and replacing parts. From my initial enquiry, communications by email and efficient, reliable and polite engineer to carry out the work, it was a pleasure to have found such a company and would certainly recommend and use again.

An efficient, punctual, professional and reasonably priced company. Highly recommended. A damaged activator in my HIU unit was identified as the reason why I had no hot water. A replacement was sourced and fitted successfully with a week.

Engineer Justin is a very careful and capable man, he identified our problems which was existed for nearly 7 years. I appreciated his service so much, as we have suffered terrible trouble for so many years. And when Justin was doing the HIU service, he kept very clean, no water dropped to the floor and around, it was amazing!

We contacted Add Detail to have a look at our faulty underfloor heating. Service was prompt and efficient. Initially it was thought that there was a faulty pump which needed to be replaced, but even once that was changed the heating still did not work. Ultimately Justin managed to fix the problem and did not charge for the new pump (this was removed and the old pump returned). Would not hesitate to contact again. An honest trader who charges an honest rate! Thanks again!
