The HomeServe Quiz ‘See the savings: the real cost of your old boiler’ uses energy savings data published by the Energy Saving Trust. The energy saving statistic is based on your property type referenced in the first question, the other questions are not used for these calculations. The savings are calculated from savings associated with upgrading from a G-rated boiler (with some controls) to an A-rated boiler (with full controls), across five different property types. All figures are based on a gas-heated home with an 82% efficient gas boiler, using a gas price of 4.18p/kWh. These figures are for Great Britain, savings may be different for Northern Ireland. Some controls = programmer and thermostat, full controls = programmer, thermostat and thermostatic radiator valves.
