  Add Detail are the best of the best and I would not use anyone one else for any of my HIU related jobs.
They do a superb job for an honest and competent price.
Justin the Engineer is an absolute expert at what he does, and every job he has done for me has been outstanding. In addition he is a great person who is professional, experienced, honest, punctual and reliable.
His partner Sigis who runs the office side of things is also most helpful when booking a job or getting a quote and is easy to communicate with.
All in all, I cannot recommend anyone better for any of your HIU needs.

  Great job!  Needed to service my boiler, the engineer came on time and checked everything thoroughly. I had some irregular problems with hot water supply and the engineer has offered very useful advice to identify the root of the problem (boiler unrelated).

  Having had an estimate from another company who demanded total payment up front by bank transfer, I decide to look at other options for HIU repair. I contacted about 5 companies. Add Detail got back to me very quickly with a much better price and only wanted the cost of parts up front which I could easily pay by credit card.
Jason the engineer arrived at the agreed time (he was early in fact) and did an excellent job, making sure that the system was working properly. He was very polite and made no mess.
I have recommended this company to others on my development as there are always people having problems with the HIU's.
