Boiler repairs in Windsor: worth knowing

Hard water across the South East can build up as limescale in a boiler's heat exchanger, which can cause kettling (a rumbling or banging noise) and reduce efficiency. Mention any noises when you describe the fault.

At the 2021 Census, 20.6% of households in Royal Borough of Windsor and Maidenhead rented privately, up from 16.2% in 2011, and 66.2% owned their home. Tenants should report boiler faults to their landlord, who is responsible for gas appliances, heating and hot water.
