Things can feel confusing in energy at the moment. As your supplier, we want to be clear about what's happening.
See below for more information.
Your energy bill has been reduced since 1 April following action taken by the UK Government in the 2025 Budget. You can find more information at gov.uk/your-energy-bill.
In the Autumn Budget, the government announced that some policy costs funded through household energy bills will be reduced from 1 April 2026. A significant proportion of energy bills are made up of ‘non-wholesale costs', including network costs, operating costs and policy costs, all of which support the running of the energy system.
From 1 April, some policy costs have been removed from customer bills, including 75% of the cost of the Renewables Obligation (RO), which will instead be funded by general taxation, and the Energy Company Obligation (ECO) insulation programme, which has come to an end.
We’ve passed on these savings directly – you can see the reduction in your rates in your online account and on your energy bills from 1 April.
“We're really happy to be passing savings on to So Energy customers, particularly at a time when there's a lot of uncertainty around the cost of energy. We've updated all our customers' accounts with their new rates, whether they're on a fixed or variable tariff, so they don't have to do a thing."
Andrew Barrowcliff, So Energy Pricing Manager.
Wholesale energy prices have risen sharply because of the conflict in the Middle East affecting the flow of oil and gas. This didn’t affect the April price cap drop because it was based on wholesale prices from before the conflict started. But the next cap, set for July, is expected to go up because it’s based on what’s happening now.
If the conflict ends soon, wholesale energy prices could drop quickly. But if the situation continues, prices could stay high as countries compete to secure energy supplies and build up gas reserves for winter.
Wholesale prices are still high at the moment, so we’re not able to offer fixed tariffs below the price cap. We’re continually reviewing the situation to keep prices fair and competitive.
Things can change fast. We’ll keep you updated as the situation changes.
The price cap sets a limit on the unit rates and standing charges on variable tariffs (such as So Flex and So Green Tracker.) It is not a cap on your total energy costs - the more you use, the more you will pay.
Changes in the price cap impact how much energy suppliers charge. If you're on a variable tariff, your standing charge and unit rates will change in line with the price cap. We'll always notify you before any changes. Our So Flex standard variable tariff rates will never exceed the Ofgem price cap.
On 1 April 2026, fixed customers have received a one-off rate reduction, as a result of action taken by the government to reduce some of the policy costs on homes' energy bills. Your rates will stay the same for the duration of your tariff.
Fixed rate tariffs: we have 12, 18 and 24 month fixed rate tariffs to help you can avoid wholesale price hikes. Your rates stay the same for the length of your contract.
So Flex: our Standard Variable Tariff which updates with the price cap every three months.
So Green Tracker: our tracker tariff which updates every three months in line with the price cap, but always stays £50 below it (£25 per fuel based on Typical Domestic Values).
New customers joining So Energy from 1 April get the new lower rates.
All customers renewing from 1 April get the new lower rates.
The Government announced at the Autumn budget it would reduce energy bills by an average of £150 for some households (around £134 for a typical dual-fuel user). Actual savings vary depending on how much energy you use, where you live and which tariff you’re on.
This depends on how policy costs were priced into the original tariff. For most So Energy customers on fixed tariffs, the rate reductions include both the Renewable Obligation (RO) and ECO4 elements.
If you joined So Energy between 27 November 2025 and 14 January 2026 on a So Hawthorne, So Kings, So Kielder or So Larch tariff, you’ve already benefited from some of the ECO savings in your current prices. From 1 April, your prices have gone down due to the Renewable Obligation (RO) reduction and a smaller additional ECO reduction. Your rates will now stay the same for the duration of your tariff.
The 6.5p per kWh off‑peak rate stays the same for customers already on So EV, as it doesn't include additional policy costs. Peak rates have been reduced to account for reductions in the RO and ECO policy costs. Your bill may be slightly delayed while we make the changes.
Note: The So EV rates rose to 8.8p per kWh on 17th March 2026. If you’re on this rate, the 8.8p off-peak rate doesn’t change, but peak rates have been reduced in line with the RO and ECO policy costs reductions.
So Green Tracker is a fixed tariff, with rates updated quarterly in line with the price cap. So Green Tracker rates will be reduced once the 1 April price cap takes effect.
Economy 7 customers on a So Flex tariff have had both their day and night rates reduced.
So Unique customers have had their peak, off-peak and super-off peak rates reduced from 1 April.
Your updated rates from 1 April are in your online account, tariff details, the So Energy app, and all new bills issued after 1 April.
No. The Warm Home Discount is still a separate scheme that provides a one-off payment to eligible households. These changes only relate to policy changes last year by the government.
We regularly check your Direct Debit to make sure you’re paying the right amount for your home, based on your tariff, where you live, and how much energy you use. If your account balance is in debit or credit, we may adjust your payments to help keep everything on track. When it’s time for a review, we’ll be in touch to talk you through your options.
