The HIU has been a long-term problem in my house, despite many technicians trying to solve the problem. Add Detail has provided effective, professional, and speedy service to fix the HIU after some spare parts were replaced. I was fully satisfied with the services. Their services are highly recommended.

A+ service. Fast, efficient, and respectful, and I couldn't be happier with the outcome. They were able to quickly diagnose and fix the issue with my heating system, and they left the area clean and tidy. I would highly recommend Add Detail Ltd to anyone in need of heating services.

Add Detail are the best of the best and I would not use anyone one else for any of my HIU related jobs. They do a superb job for an honest and competent price. Justin the Engineer is an absolute expert at what he does, and every job he has done for me has been outstanding. In addition he is a great person who is professional, experienced, honest, punctual and reliable. His partner Sigis who runs the office side of things is also most helpful when booking a job or getting a quote and is easy to communicate with. All in all, I cannot recommend anyone better for any of your HIU needs.
