With another tough winter for energy bills on its way, now is the time to look at how to use less gas and electricity in your home.

The Ofgem energy price cap is set to rise 5% from 1 January 2024. While bills are likely to come down again over the course of 2024, a difficult three months are on their way for many households.

For many, bills are likely to be more expensive they were last winter because they Government hasn’t introduced another £400 energy bills grant. If you’re struggling with your finances, look at our help with gas and electricity bills guide.

How much does energy cost?

As well as having a play on our calculator, we thought it would be helpful to run you through what energy prices currently look like.

The majority of households are sitting on the Ofgem energy price cap. The exact unit rate you will pay under the cap depends on where you live and what kind of meter you have. Your final bill is also determined by your usage and the type of property you live in.

Under the current cap, the energy regulator says energy bills would cost around £1,834 a year for the average dual-fuel household paying via direct debit. The next Ofgem cap, which kicks in in January, is higher at £1,928 a year due to a surge in wholesale prices in October and early November. Here are the average unit rates you pay now, and what they’ll be in the new year:

Current energy price cap rates from 1 October to 31 December 2023 New energy price cap rates from 1 January to 31 March 2023
Gas Unit rate: 6.89p per kWh. Standing charge: 29.62p per day Unit rate: 7.42p per kilowatt hour (kWh). Standing charge: 29.60p per day
