I have a HIU for hot water and heating. My unit needed a repair but it was impossible to find which spare part needs replacement. Tried 3 different specialists before turning to this company and each guy suggested a different part being the faulty one. Sigis from Add Details Ltd fixed my water issue on his first visit. On his next visit he replaced a small part and my HIU was running perfectly. Both water and heating working great for a fraction of what other HIU service companies were quoting. I can't recommend enough these guys.

My partner contacted add detail to service our heat exchange unit and not long after we started to notice an increase in our hot water bill. Me and my partner decided to contact Evinox who manufacture our heat exchange unit and they confirmed to us that the actuator inside our HIU was left loose. In hindsight I should have read the reviews before contacting carprenters to service our heat exchanger unit because they clearly do not have the knowledge required to work this type of system.

Wow!! Add Detail delivered exceptional service resulting in a very positive experience and total peace of mind. Highly professional, extremely competent and proactive. "Can do attitude" with a smile. My HIU had been leaking since Christmas and had not been serviced in many years. I was concerned that the HIU wasn't fixable and that a costly replacement HIU was the only option. Justin looked at the leak and fixed it without any fuss. He was also proactive and did extra work and checks to make sure the job was finished to a very high standard. He also took the time to talk about HIU repairs versus replacement even outside office hours. I will be recommending Add Detail to my Estate Management Company so other residents in my building can use them for HIU repairs/replacement/annual service.
