Approximately four million, 15% of UK households are not on the mains gas grid. These off-grid households have to rely on a range of other fuels such as oil, LPG, coal, etc. to keep warm. The average cost of heating a typical three bedroom off-grid house is estimated to be between 50% and 100% higher than if it were connected to the mains gas supply.
