Very professional, easy to book and on time! Just sent an email and the next day I had someone to check the boiler.
Paying is also easy, as you can choose credit card and also Google Pay accepted.

I contacted Add detail for a leaking HIU, I used the online booking service allowing you you to book time, date & send photos, the request was followed up the same day with an email allowing to add more details & confirmation of booking. The engineer arrived exactly at the time stated, they were very polite and professional & explained everything what he was doing.
I am very pleased with the service provided & will be recommending them to my neighbours for annual servicing & maintenance.

Our HIU radiator needed repair during the snow storm in London last week, Add Detail is the only repair responded after calling/emailing five repairers. Quick response and detailed report after fixing, highly recommended. Will definitely call them again if I need anything for HIU repair
