Ofgem’s energy price cap to rise by £21 a year in January

4 min Read Published: 22 Nov 2024

Energy price cap to rise by £21 in January 2025Energy regulator Ofgem has announced that typical household energy bills will rise by £21 per year from 1st January 2025. It represents a 1.2% hike, meaning the average dual-fuel energy bill will rise from £1,717 to £1,738. To estimate how the latest rise is likely to impact your own energy costs you can simply add 1.2% to your energy bills, so those currently paying £150 per month will be paying around £151.80 come January.

The new energy price cap will be in place from 1st January 2025 to 31st March 2025 and is set by Ofgem, the energy regulator. While the cap will be £21 more per year than the previous energy price cap set in October 2024, it is £180 per year less than in January 2024 and £2,321 less per year compared to January 2023, when energy prices hit their peak.

With rising inflation and recent cuts to the winter fuel payment, many will be concerned about another increase in energy costs. Below, we explain why energy bills are going up, how much you will pay under the new price cap and also what you can do if you are struggling to pay your energy bills.

Why have energy prices risen again?

The war in Ukraine continues to impact the energy market and gas and electricity suppliers are facing higher prices, which are being passed on to consumers. While prices have risen, a 1.2% hike is far lower than the 10% hike we experienced in October. Craig Lowrey, principal consultant at energy analysts Cornwall Insight stated "Supply concerns have kept the market as volatile as earlier in the year, and additional charges have remained relatively stable, so prices have stayed flat. While we may have seen this coming, the news that prices will not drop from the rises in the autumn will still be disappointing to many as we move into the colder months".

What is the energy price cap?

The energy price cap was introduced by the government's energy regulator Ofgem (Office of Gas and Electricity Markets) to control the maximum amount that providers are allowed to charge consumers for each unit of gas and electricity. Prior to the energy crisis, the price cap was reviewed every six months. However, with the wholesale energy market experiencing unprecedented volatility in 2022, Ofgem moved to a quarterly price cap review. The energy price cap represents the average annual dual-fuel household bill that is paid via direct debit.

The energy price cap is based on the average dual-fuel household bill and how much you will actually pay will vary depending on how much energy you use.

Those without a smart meter should make a note to take a meter reading as close to the 31st December as possible so as to ensure your readings are accurate and you pay the correct price for your energy.

What will happen to the energy price cap in the future?

According to the latest predictions from energy analysts Cornwall Insight, the energy price cap could fall to around £1,713 in April 2025, the next point at which it can change. However, Energy supplier EDF has a price cap forecasting service that predicts that prices could go up a further 2% to around £1,777 per year. What this goes to show is that energy price forecasting is complex and there is no certainty as to whether energy prices will rise or fall in the future. Ultimately, there are many factors that can influence the wholesale market price for gas and electricity, so if you are worried about future price rises, you may be better off considering a fixed price tariff. We explain more below.

Is now a good time to switch to a fixed energy tariff?

In response to the latest energy price cap increase, Tim Jarvis, a spokesperson for Ofgem said "We understand that the cost of energy remains a challenge for too many households, however, with more tariffs coming into the market, there are ways for customers to bring their bill down so please shop around and look at all the options."

The energy price cap changes every 3 months, while fixed deals typically last 12 or 24 months. The danger with fixing your energy costs is that should you fix, a better deal may be just around the corner. Conversely, however, a fix may result in a relatively low bill if prices subsequently soar. The real benefit to fixing your energy deal is the assurance that you know exactly what you will be paying for your energy over a set period. While better deals could come to market during your fixed period, you are protected should there be a sudden surge in energy prices. However, there are more energy deals coming to market that do not charge exit fees, leaving customers free to switch if a better deal becomes available.
