Very responsive, professional, and did a HIU service for us. Thank you!
These guys are very, very good. Up to now, we have struggled to find people who really know what they are doing with HIUs. The guys at Add Detail specialize in these systems, and know everything there is to know about them.Apart from that, they are a truly professional outfit. Their communication is consistently prompt and clear, they are reliable, and extremely thorough. You are never left guessing; they always make it clear what they will do, when they will do it, and what it will cost: and they stick to it.They are also very nice guys, and happy to share their knowledge so that you understand your HIU system better. I cannot recommend them highly enough: really great.
Great service from Add details. Helped me to install the unit within a week's time as it just got colder. Sigis has been very responsive during both phones and emails. And Justin & Dave were both very punctual - during both inspection and installation. I would recommend their service to anyone who lives in apartment with HIU unit to repair or replace. Great value, hard working engineers and great customer service!

It will be difficult to provide an accurate review after using Add Detail service only once nevertheless for me it was a 5/5. The HIU on my flat was serviced and the pump identified as stuck. I called Add Detail and gave me an appointment after 4 working days, not too bad considering it was winter time when most heating units are found faulty. The engineer arrived early which I appreciated and fixed the problem within 30 minutes. His job was clean and professional and overall I am happy with their service. As advised on their website I feel I paid a fair price for the job compared to other companies or contractors I have used before. If their work is consistently provided with the quality I has perceived I would recommend them and hire their services again.
Fast and very professional, transparent and responsive.
Excellent HIU servicing and repairs carried out by courteous and knowledgeable engineers. Cannot recommend Add Detail more highly- professional, tidy and fair priced.
Very professional service on my HIU. Happy to use them again in future!
Decent service and reasonable servicing price - recommended!
