[H2] How to join our next Sunday Saver challenge

I'm with EDF

I'm not with EDF yet

[H2] How does it work?
Everyone who signs up for the challenge will get a target to shift some of their electricity usage away from peak hours (usually 4pm to 7pm)(1). The more you shift during the week, the more free electricity you can earn. For example, if you shift 50% of your peak usage, you can earn up to 16 free hours to use the following Sunday. To join, visit Energy Hub in your MyAccount monthly and sign up for the challenge. If you miss the sign-up deadline, don’t worry; we can send you an alert when the next challenge sign-up period opens. Request a Sunday Saver reminder. To join, make sure you have a smart meter that sends readings every 30 minutes or set it up for 30-minute reads.Join the challenge in Energy HubDon't have a smart meter yet?

[H2] It's now even easier to earn free hours!
We've been busy making updates! Watch our video to learn about all the changes we've made.We would definitely take part again"We found the Sunday Saver challenge trial really simple. We managed to reduce our electricity by ensuring we didn't do any clothes washing, use the dishwasher or charge a car between 4–7pm. With the free hours we earned on Sundays, it’s been great to do as much as possible such as washing and charging things around the house."Michael and Julie Parker earned 192 hours of free electricity on our Sunday Saver trial

[H1] Energy price cap predictions
Take the mystery out of energy prices!Our price cap forecast is designed to help you understand if your home's energy should be on a variable tariff that follows Ofgem's cap price, a fixed rate tariff for price certainty, or a tracker tariff with discounted standing charges and cap rates.

[H2] Take control of your energy
As Britain’s biggest generator of zero carbon energy(1), we've a deep understanding of the energy market. This allows us to predict future changes to the Ofgem energy price cap, or the Default Tariff Cap, as it’s also known.  Each week we update this page with new information about changes to the cap's energy prices, and how it affects your energy tariff choices should you want to switch supplier or tariff.

[H2] Price cap predictions - changes coming in
Important: Ofgem is changing the “typical consumption” figures used for average bill calculations from 1 July 2026.Quotes created before 1 July use the current typical consumption valuesQuotes created on or after 1 July use the new typical consumption valuesThis means average annual bill figures shown before and after 1 July may look different, even if underlying energy prices have not changed.
[H3] Current typical consumption values (used before 1 July)
Electricity: 2,700 kWh/yearGas: 11,500 kWh/year
[H3] New typical consumption values (used from 1 July)
Electricity: 2,500 kWh/yearGas: 9,500 kWh/year
[H3] Comparing price cap predictions
To make fair comparisons over time, compare figures calculated using the same typical consumption values. Otherwise, changes may reflect updated usage assumptions rather than actual price movements.

[H3] Price cap predictions using the new Ofgem typical consumption figures
When comparing how the SVT cap will change over time, ensure you are looking at prices calculated using the same typical consumption figures.*See annual bill figures using Ofgem current consumption (2)

[H2] Are energy prices going up or down?
The indexation period for the next price cap starting in July 2026 has ended and the cap level is expected to be higher than the current level (Q2 2026) by £208. The cap level for Q3 2026 is also expected to be published based on the proposed new typical consumption figures mentioned above, or £1,663. From Q4 2026 onwards the wholesale prices have reduced from last week. There is potential for further market price changes in a short space of time which would impact these later price cap periods.

[IMG: Friends talking in a bright sunny kitchen]

[H2] How are energy prices predicted to change in 2026?
On 25th February, Ofgem announced the current price cap for Q2 2026 at £1,641. Future cap periods, for Q3 2026 and beyond, have low certainty as costs are not confirmed this far in advance.

[H2] See if you can save: compare our tariffs against Ofgem's price cap
Based on our current predictions, a one-year fixed tariff that costs £1,908* or less annually at current consumption levels could save you money, rather than staying on a variable tariff that tracks the cap over the year.*This is equivalent to £1,730 at the proposed consumption levels from July 2026 (2.5MWh for electricity and 9.5MWh for gas).*See annual bill figures(2)

[H2] Our tariffs
We offer two classic types of gas and electricity energy tariffs: fixed or our tracker tariff which follows Ofgem's price cap, but is always priced lower than the cap. If you're on a fixed energy tariff, the changes to the price cap won't affect your energy prices. If you're a variable energy tariff then the price cap prices will affect how much you pay for your energy. We also offer tariffs for solar panels, air source heat pumps and electric vehicles.

[H2] Ofgem’s current price cap
The current price cap runs from 1 April to 30 June 2026 and is set at £1,641 on an annual basis. This is the national average price paid by a typical domestic customer paying by Direct Debit(2). Don’t forget, it’s the standing charge and cost per unit of energy that Ofgem sets, not your bill. Your energy bill will vary depending on how much energy you use.

[H2] What is the energy price cap and how does it work?
The energy price cap broken down: It controls the cost that providers can charge customers for their energy Ofgem, the government’s regulator, change the price cap every three months to reflect global changes in the wholesale costs of energy, and other factors As energy providers have already paid for the energy they sell, the price cap actually reflects the costs from three months ago, rather than wholesale costs now So, to keep on top of your energy bills, it’s important to think about the future costs of energy.

[H2] Why do energy prices go up and down?
As a country, we don't make all the energy we actually need. This means we have to buy energy from global wholesale markets, where all countries compete to buy energy. When it comes to buying energy, there are many factors that affect the wholesale prices, for example:Geopolitical instability - this is one of the key reasons for energy prices rising - we saw this when Russia first invaded the Ukraine, and conflicts elsewhere in the world, also affect energy pricesPower plant outages - rising temperature has been blamed for certain power plants choosing to reduce production due to safety concerns, and also planned power outages can affect energy pricesReduced renewables production - similarly, low winds and power outages have increased the cost of gas production - with renewable energy linked to gas prices, this has increased the cost of renewable energy pricesColder weather - every year, when the weather gets cold and we have longer, darker evenings, we use more energy - this demand for supply pushes wholesale prices upThese are just a few of the reasons why energy prices fluctuate, and one of the main reasons we're proud to be Britain's biggest generator of zero carbon electricity(7) and doing everything we can to help build Britain's energy infrastructure.

[IMG: EDF engineer working with an angle grinder]

[H2] What we’re doing to help bring down energy prices
We’re investing all our profits into building more renewable and nuclear power to help reduce Britain’s reliance on buying gas and electricity in from around the globe  We’re continuing to call for government to introduce a social tariff for those on low incomes Helping our customers earn free electricity on Sundays by shifting their usage away from peak timesOffering tariffs priced below the price cap: beat the cap by £50 a year with our tracker tariff!(3)

[H2] How else to cut energy costs
We're all looking for ways to save energy and money in our homes! Here're some simple, but effective ways you can easily make a difference to your monthly bill:Switch off at the wall! The Energy Saving Trust estimates switching devices off standby could save you £45 in GB and £55 in NI a year! Switch lights off when you leave a room!
