Different energy sources are measured in different units: litres, therms, BTU, kWh, units, cubic metres and many more. This makes it very difficult to compare the actual costs for powering a heating system between differing energy sources.

For this reason, standardised units and costs are needed. We have done these calculations for the main fuel types. In making these calculations sources of data and assumptions have been used; these have been referenced. We update this monthly, however, we recommend the reference sites be checked for the latest fuel prices.

Average prices shown are based on the supply of fuel volumes suitable for a medium-sized domestic property (around 16.5MWh of annual heat demand), quotes taken from suppliers within the East Midlandss region.

We only publish the last three months of data at any one time. If you require any archived tables we will supply this information in pdf format.
