LONDON HIU ENGINEERS

He also took the time to talk about HIU repairs versus replacement even outside office hours.

Bob C from Isle of Dogs East London – E14. ( 11th of May )
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.

Rollo C. from Dalston, North London – N1 ( 19th of May. )
Add Detail did a great job replacing 7 values on my HIU. Justin was helpful and super easy and straightforward to deal with. I would definitely recommend.

Highly recommend this firm.

James O, from Poplar East London – E14. ( 25th of May. )
Excellent service from the first point of contact. Very flexible when I wanted to change dates which they accommodated as I had a fairly urgent problem. The workmanship was excellent as was the follow up visit to fit the new parts needed to repair my HIU. The job was completed quickly with the minimum of fuss and no mess. Highly recommend this firm.

I'm a landlord of a flat in a relatively new development, which uses shared heating through a system that I don't know much about. HIUs. I tried to use a recommendation that came through the development residents but this person continuously did not give me confidence and also the quote seemed unreasonable. I called HIU and they were transparent with their fees and came when they said they would and did the repart at a fair price. I would highly recommend them. This was back in August 2021 and I've only just got.around to putting this write-up on to here. Good as it means the repair is still fine.

Had my HIU service done for the 1st time with these guys. Work was clean and not rushed. Had an issue with starting up my heating which was resolved and also an issue with a leak which required further work which I will be asking these guys to carry out for me. Was recommended these guys and I will be doing the same. Great work.
