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.
