HIU Repair Services London

Heat Interface Units (HIUs) are now commonplace in new builds, they vary from traditional heating systems in the way of not needing an individual gas supply, however, should yours stop working, as with any other heating system, you will want to get an engineer out as soon as possible. All our London based HIU repair specialists are highly equipped to diagnose faults quickly and on the first visit, saving you time and money.

A faulty HIU can cause numerous problems:

  • It can compromise your safety by making you vulnerable to mechanical and electrical accidents.
  • It can increase your heating consumption, increasing your bills.
  • It can create the need for complete HIU replacement if you don’t repair the system on time.

At Add Detail HIU Repair Services, we can help you prevent all of the above problems by providing timely support at fair and pre-determined prices. We have been working in the London HIU industry for over 15 years, helping customers with HIU installation, repairs and servicing. In this time, we have built a reputation for excellence and this is reflected in our fantastic reviews.

How we diagnose your HIU for problems

Typically, an HIU needs repairs when it displays the following signs:

  • There are strange noises coming from the unit
  • The HIU constantly keeps turning on and off
  • The system setting seem to change even if you don’t manually change them
  • The water temperature isn’t consistent each time
  • There is condensation on the windows

The team at Add Detail HIU Repair Services visit your home to conduct a thorough diagnostic of your unit, using a variety of tests to identify the cause of the problems and recommend a solution, paired with an up-front quote for the repair work to be completed.

Once we identify the problem with your HIU system, our experts will provide the repairs needed. Here are some of the things we normally do during an HIU repair:

  • Check for leaks or cracks in the HIU casing
  • Circulation pump performance check
  • Temperature control system and heat meter repair or replacement
  • Cleaning the strainer filter
  • Repair or replacement of the differential controller valve
  • Re-pressurising of the expansion valve

Excellent service of our HIU and cylinder.

James Spencer from Canary Wharf, East London – E14. ( 6th of July )
Excellent service of our HIU and cylinder. Friendly, professional, and good price for the job. Recommended.

I can't recommend enough these guys.

Petros C. from Barking, East London – IG11. ( 3rd of July )
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.

Very efficient HIU service.

Kat Young from Wanstead, East London – E11. ( 2nd of July )
Very impressed with how quickly we received a quote for a part and labour. It was much cheaper than I had quoted elsewhere and was very efficient too.

We were really happy with their service and would definitely use again - Sigis was very prompt and efficient, and all at a really reasonable cost!

HUI MAINTENANCE Very good service.

William K. from Silvertown, East London – E16. ( 21st of June. )
HUI MAINTENANCE Very good service. Justin, the engineer who visited, was nice and professional. That day, he had to climb 8 floors with his equipment because the building’s lifts were out of order and didn’t complain! He asked a few questions about the status of my heating unit and went about his business while I was on a work call. Once I was free again, he explained to me in detail what he was doing. He answered my queries, most importantly got my radiators, which had stopped working this winter, up and running again and gave me a few tips with regards to general maintenance. And he acquitted himself without leaving a mess in my utility room. I’m very satisfied.

I would gladly recommend them.

Johan Harmse from Canning Town, East London – E16. ( 9th of June )
These guys did the annual service on my HIU unit, and delivered a really pleasant and professional service. I would gladly recommend them and will be using them again next year.

Very reasonable price and extremely pleased with the work done!

J Gordon from Canary Wharf, East London – E14. ( 2nd of June )

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.

Danfoss HIU valve replacement.

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.

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.

They were really good on communications, offer competitive price, have excellent technical skills and most importantly good people. They also went extra miles for me to accommodate my request and yes I am extremely satisfied. There are so many “bad job” delivered by some plumbers and engineers. They are not one of them, my neighbor also started using them as well! Thanks 🙂

Justin quickly identified the issue and fixed the HIU right away

Sylvia Wu from New Cross, South East London – SE14. ( 7th of April )
I chose Add Detail based on the positive reviews on Google and TrustPilot and it has been a fantastic experience. Thanks very much Sigis for sending an engineer literally 4 hours after booking. Justin quickly identified the issue and fixed the HIU right away + checked all the radiators in the flat. Very much appreciate the efficiency and professional service, just as suggested in other reviews 🙂 Would be more than happy to choose Add Detail again and recommend to friends. Wish you all the best.

Justin found the issue and resolved it less than 24 hours after the leak had been found. Really impressed with Add Detail - very professional and go out of their way to help as much as they can. I will definitely be using them for all my heating/plumbing moving forward and would highly recommend them to anyone considering using their services!

Manny Sandhu from Islington, North London. ( 2nd of February )
I called Add Detail after another HIU repair service told me that my unit needed to be replaced because parts were discontinued for my 8 year old unit. This would have cost nearly £4k. I called Justin at Add Detail for a second opinion. He was able to source the parts and fix the unit for a fraction of the cost. Excellent service. Honest guys. Would definitely recommend.

I will certainly be using Add Detail team again in the future

Karetha SB from Islington North London ( 8th of September )
I needed a some work doing to my downstairs cloakroom/toilet and contacted Add Detail once restrictions had been lifted. After meeting Sigis it was clear that he was very experienced so I asked him to do a full refit in our downstairs toilet, plus some extra work in the upstairs bathroom to modernize it. The building was built in the 1960's and the toilet itself had exposed pipes everywhere and was really in need of a face lift. Sigis, Justin and George were an absolute pleasure to work with and they really turned my vision into a reality. They were always prompt and tidied up at the end of each day which was great as I have a very inquisitive toddler. I am over the moon with the results and would highly recommend them. I will certainly be using Sigis and his team again in the future. 🙂

Our work was completed on time and we were most satisfied

Merlynne Robinson from West Hampstead North West London. ( 4th of September )

I have absolutely no reservations in recommending Add Detail!

Emma Davey from Holloway, London. ( 26th of May )
We first used Add Detail Plumbers over a year ago in our flat. We had water pressure issues that nobody else was even willing to put the time in to explore. Justin was systematic in his approach and quickly resolved the problem. We then decided to have a pump installed on the shower and he talked through all of the different options explaining clearly the positives and negatives of each. Justin completed the job efficiently and to a high standard - our tenants were very happy with their new shower. We have since requested Add Detail's services at our house - to investigate an outside leak and plumb in two sinks and a washing machine. Justin always attends within 24 hours, which in the case of the leak was very reassuring (and it was Good Friday). Again he quickly identified the cause and fixed our cistern and carried out our plumbing brilliantly. I have absolutely no reservations in recommending Add Detail!

A very positive experience

Laurence Higgens from Finsbury Park, London. ( 12th of May )

Really happy

Victoria from Vauxhall, London ( 10th April )
"Add Detail team helped me renovate my bathroom in March 2017. I wanted to move fixtures and turn the room into a wet room. This is the first time I have ever done anything like this and Sigitas was really helpful at advising me on what we could do and what would improve the look. He helped me review the list of fittings to ensure I had everything and what I had would work. The project was estimated at 3 weeks and ran over by 2-3 days but I cant fault that the team worked hard and long days and the overall result is worth it. The final result is excellent - it looks like a hotel bathroom so I'm really happy."

Efficient company

Dominic Kasteel from Islington, London ( 6th June )
"If you have wished you could find a builder whose prices are reasonable, who listens thoughtfully and advises well, arrives on time and works with care and precision, cleans up at the end of the day and delivers everything promised to budget and deadline, you will be relieved to know that one actually exists! We were shocked when the newly laid tiles of our wet-room floor started to lift and looked as if they had been stuck down with fudge, not adhesive. It was hard to see what the solution might be, but ADD DETAIL undertook the job and two years later it still looks absolutely perfect, with a couple of little improvements we did not even ask for. ADD DETAIL have now fitted a new kitchen, with appliances and custom-made cabinets for the boiler and a washing machine and freezer. Somehow they have used the space better than before and our drawers are bigger and everything fits and looks perfect. This is a small, friendly and efficient company that gives you immediate confidence, because they listen carefully and advise sensibly. Their prices appear to be somewhere in the middle, which is a very pleasant surprise, given the very high standard of service and the peace of mind they offer. "

Honest service

Susie Barson from Finsbury Park, London ( 29th June )
"This was my second experience with Add Detail. I think it was Justin who made the call. He fixed a leaky pipe and sealed the joint where the top meets the sink. Hopefully this will last for a while. Very good efficient, professional and honest service, thank you!"

Fantastic service!

Joanna from Archway, London ( 12th September )
As a landlady, I have found it difficult in the past to find good workmen, particularly when the job requires both a plumber and a carpenter, but Sigitas & Justin stepped up to the plate and did a wonderful, high standard job. They do not have no in their vocabulary or try to pass you off on to other workmen, which is refreshing. I have since given them other jobs, as I am so pleased with the results. I have found them to be entirely trustworthy, friendly and hard working. Also, their prices are reasonable in comparison with other firms. Add Detail will be my first port of call in the future and I cannot recommend them enough.

Great Attention to Detail

Basi from Hackney, London ( 18th September )
We really could not be happier with the job or more satisfied with the experience of working with Add Detail. It was the attention to detail that made all the difference - there were no cut corners and everything finished to a very high standard. It was also fantastic that you were always reliable, exceptionally clean and came with many constructive ideas. We're delighted with the results and would highly recommend.

Trustworthy and talented

Beth Watson from Camden, London ( 13th February )
"Excellent - Add Detail team is exceptionally professional, trustworthy and talented. The quality of workmanship was brilliant. Sigitas took time to listen to what we wanted and worked incredibly hard to achieve the almost impossible in our kitchen through his skill in creating a bespoke design. Aftercare was also fabulous - if we had any questions or concerns, Add Detail team was on hand to advise. We would highly recommend Add Detail without reservation. "
