I've just moved out of the area so regrettably won't be able to use AOS any longer We had a monthly pay maintenance contract with them for 15 years. Our old house although new appeared to have inherited a rather flaky boiler that needed 3 PCB replacements…

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.
