Energy Cost Comparison
Different energy sources are measured in different units: kWh, therms, BTU, cubic metres, litres and more. This makes it very difficult to compare the actual costs for powering a heating system between different energy sources.
In order to make a fair comparison we need standardised units to determine costs. We have made these calculations for the main fuel types. In making these calculations, sources of data and assumptions have been used and referenced. We try our best to update this information monthly, and have been doing so regularly since 2007. We don’t have any sponsors.
Average prices shown are based on the supply of fuel for a medium-sized domestic property (around 12,500 kWh of annual heat demand per year). Quotes are taken from suppliers within the East Midlands region. Standing charges are included in the kWh price.
Never miss another update! Provide us with your details and we’ll send you an alert email when next month’s data is available to view.

*C02e emissions are based on UK Government GHG Conversion Factors for Company Reporting. The CO2e emissions factors used encompass Scopes 1,2 and 3. Scope 1 and 3 are for all fuel types except electricity which uses Scopes 2 and 3. The Scope 3 emissions include emissions associated with extraction, refining and transportation of primary fuels prior to combustion/use in electricity generation; and emissions from Transmission and Distribution.

*C02e emissions are based on UK Government GHG Conversion Factors for Company Reporting. The CO2e emissions factors used encompass Scopes 1,2 and 3. Scope 1 and 3 are for all fuel types except electricity which uses Scopes 2 and 3. The Scope 3 emissions include emissions associated with extraction, refining and transportation of primary fuels prior to combustion/use in electricity generation; and emissions from Transmission and Distribution.

We have used the CO2eq factor of LPG, as both propane and butane are components of LPG and there is currently no specific GHG conversion factor for these
Kiln dried logs: Based on an average prices from Fuel Sell, HomeFire, and Wirksworth Logs. We have used the CO2 factor as there is currently no specific GHG CO2eq conversion factor for this. Note: The values for seasoned logs have been updated based on the latest information on the Net CVs of Seasoned logs from Biomass Energy Centre.
Wood Pellets (Bagged): Based on average prices from Balcas Energy.
Wood Pellets (Blown Bulk): Based on average prices from Balcas Energy.
Smokeless fuel and coal: Based on average prices from House Fuels, Coals2U and Homefire. We have used the CO2eq factor of coal, as the components of smokeless fuels are coal-based and there is currently no specific GHG conversion factor for this.
GSHP (Ground Source Heat Pump) and ASHP (Air Source Heat Pump): Based on best electricity price taken from electric standard rate. The boiler efficiency used in the calculation is based on the best available information from Interim Insights from Heat Pump Performance Data 2022.
