LONDON HIU ENGINEERS – SAME DAY VISITS AVAILABLE

They explained what was happening

Alfredo M. from Kings Cross, Central London – WC1. ( 1st of March )
Great experience! Their work is very clean, they explained what was happening and how the new HIU system works. Would recommend to anyone.

Finally fixed the HIU

Odile from Highgate, North London – N6. ( 14th of February )
Justin went beyond and above excellent customer service. I locked both of us outside the flat 24 hours after having changed the lock. Not only did he stay trying to help, but he waited with me for 1 hour for a locksmith to open the door. He was very polite and at no time showed any frustration. I greatly appreciated his non judgement and his support, helping me accept things like this can happen. Once we eventually could get in my flat, he finally fixed the HIU. Although I was his last customer, no other service and utility providers would have waited while being so calm and polite about the situation.

Really professional HIU company

M. K. from Greenwich, South East London – SE10. ( 5th of February )
Adddetail were the third company I asked for help after previous 2 were incapable of fixing an HIU leakage. After the second company wanted to replace part of HIU for 530 GBP, I called Adddetail who were in the area. They spent 15 minutes and charged only 36GBP in total for fixing. Really professional.

Fantastic service provided by Add Detail! 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.

Add Detail Ltd are very professional. Justin was on time, did the HIU annual service by thoroughly checking the HIU and the radiators. He also fixed a problem with the hot water, without extra charge. Add Detail did a great service at a fair and reasonable price. I will highly recommend them.

Prompt, efficient, professional service. I’m an overseas landlord but communicating with Sigis and booking jobs have always been easy. Had to have my HIU replaced recently and glad to have placed my trust in them.

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.
