Boiler and heating system not functioning properly. Called in Homeserve with whom we were under service contract. After 2 days of ineptness they left us in a worst state as the fitting of a new pump introduced copious amounts of air into the system and a leak left us with a damaged ceiling. Spent the last 4 nights with no heating and no hot water. Called British Gas on Sunday morning, had an engineer with us at 10.00 on Monday morning and by 10:40, the heating system was purring! Committed to spend £300.00 over 12 month for 3 star cover that looks after my complete heating system. Money well spent methinks...absolutely delighted with speed of response, professionalism of engineer and the result. Thank you!
