Well British Gas is simply a terrible company to deal with. British gas wrote my boiler off, even though it had been serviced just 3 weeks earlier saying the galvanised metal has rusted within the boiler!! We therefore had no heating or hot water. British Gas promised to install our new boiler (a top of the range Worcester) and zone our house to allow each floor to be individually controlled with a hive! After installing the boiler they refusing to complete the job. Please be aware that they lie bout what they offer! I would award 0 start if available. Please avoid, they are not cheap and their after sales service is terrible!
