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.
