Tim, Cheshunt

The engineers were on time and very professional. Didn't stop until lunchtime, would not even have a cup of tea. Very clean and efficient, did a brilliant job at bricking up the old flue hole in the brick wall. They are coming back to do some more work for us,…

AOS installed a new boiler in my property. The two installers were punctual, polite, tidy and efficient. Their work combined with the excellent admin support from the office showed the professionalism of both the installers and the company.

A.O.S fitted a new central heating system i.e. boiler, radiators and thermostatic valves. They were punctual, hard working and very efficient. I would certainly recommend their workmanship
