Report
Very professional company and staff from start to finish, removed old boiler and all allied parts, repositioned new combi boiler. Very clean, polite engineers and fast, boilers been in since June, so two months, not the cheapest quote but very happy we used this company. Needless to say will be using AGS for further works if needed and recommending to family and friends. Thanks.
