How do I estimate my energy bill?

Multiply your electricity usage (kWh) by the unit rate, add the standing charge, then do the same for gas if applicable. Our calculator does this automatically with current UK default rates.

What is a standing charge?

A standing charge is a fixed daily fee your energy supplier charges regardless of how much energy you use. It covers the cost of supplying energy to your property and maintaining the network.

Can I calculate gas and electricity together?

Yes — toggle 'Include gas' in this calculator to add gas usage, unit rate, and standing charge. You will see separate breakdowns for each fuel plus a combined total.

Energy Bill Calculator

Your energy bill = (Usage in kWh × Unit rate) + Standing charges. The average UK household pays around £1,568/year for dual fuel under the current price cap.
