We recently carried out a boiler repair for a family near Vicarage Road, where the heat exchanger had cracked due to a limescale build-up common in London's hard water areas. Our engineer sourced the correct part and completed the repair the same afternoon, restoring full heating and hot water before the evening. This is the kind of swift, local service we are proud to deliver.
