Add Detail Ltd

After two terrible experiences with other companies, I discovered Add Detail through a Google search. I messaged them on WhatsApp and received a prompt reply. A few days later, Justin came over and delivered impeccable service. Despite being initially informed that I needed a full HIU replacement, Justin skillfully replaced the malfunctioning pump, leaving everything fully operational! He was incredibly nice and helpful. I plan to rely on Add Detail for all my future HIU servicing needs. I highly recommend them.

Justin, who dealt with my HIU queries had been very responsive in answering all my questIons and providing a number of quotes upon request. I had an intermittent hot water issue and needed my HIU to be fixed. The first service booking did not resolve the problem so had to book a subsequent appointment (would be ideal if it was resolved at the first service without incurring additional call-out/labour costs and time). I am personally not a fan of multiple appointments as the job could have completed in one booking in my opinion. The subsequent appointment quoted was to clean out the heat exchanger only but this did not give me confidence in resolving the underlying issue so I had an independent engineer to verify if problem lies with the IHPT valve. They indeed confirmed it was a faulty IHPT and needed replacing. Although the independent engineer charges cheaper to do the repair on my HIU, in the end I gave the job to AddDetail because I value Justin’s customer care and his responsiveness. Again, although AddDetail are not the cheapest, they provide a good quality service you can trust and rely on. If the price is right, I surely be using your services again in the future. Keep up the good work!

We always use Add detail to service our HIU boiler. They are professional, knowledgeable and efficient. Thanks guys.

I have Add Detail service my HIU Heating System every October. I choose October because the heating will already be on for winter and if there is a fault, they can fix the fault at the same time as the service. So far, after several years, I have had no faults. I put this down to the system having a very good service every year. Add Detail are very professional, very punctual and very efficient. They give the heating system a fully comprehensive service at a competitive and fair price. I would recommend Add Detail wholeheartedly.

Justin from Add Detail attended to my flat to install new smart thermostats for my underfloor heating and to help me map the manifold actuators with correct areas of the flat, and also checked my HIU. Justin patiently explained everything. Previously I had horror experiences with a large contractor imposed on us by our building's freeholder/ their managing agent, so I am so glad I have found Justin. Also very fair pricing per hour. Have recommended Add Detail HIU to neighbours in our building needing help as well.

I am absolutely delighted with my experience using HIU Servicing Service. Not only did they offer competitive pricing, but the professionalism on display was top-notch. The engineer was punctual and incredibly skilled—making the entire process seamless. I highly recommend them to anyone needing quality service without breaking the bank.

Very pleased with professional service provided and further advice given. Hassle free billing services. Invoice sent via email immediately after service was provided.

Exceptional company to deal with. Great communication, always responsive and carried out excellent work on an HIU including service and replacing parts. From my initial enquiry, communications by email and efficient, reliable and polite engineer to carry out the work, it was a pleasure to have found such a company and would certainly recommend and use again.

Add Detail provided a great service and a detailed report with recommendations. The engineer was happy to chat and give detail about the system he was servicing and reasons for the recommendations. Overall very happy with the service received.

An efficient, punctual, professional and reasonably priced company. Highly recommended. A damaged activator in my HIU unit was identified as the reason why I had no hot water. A replacement was sourced and fitted successfully with a week.
