The UK government has announced changes to how certain energy policy costs are funded, with the aim of reducing household energy bills from 2026. While the headline figure suggests that households could save around £150 per year on average, the reality is more nuanced.
Not every household will see the same level of savings. How much you benefit will depend on your energy supplier, tariff type, and how your current bill is structured.
This article explains what is changing, why savings may differ between households, and who is most likely to benefit.

What Is Changing in 2026?
The planned reduction in energy bills comes from changes to how environmental and social policy costs are paid for.
Two key elements are involved:
- Some green policy costs that were previously included in energy bills are being moved to general taxation
- The Energy Company Obligation (ECO), which funded energy efficiency improvements through customer bills, is set to end in its current form from April 2026
Together, these changes reduce the policy costs built into electricity and gas bills. For a household using a typical amount of energy under the price cap, this is where the estimated £150 annual saving comes from.
Why the Savings Are Not the Same for Everyone
Although the policy changes apply nationally, energy suppliers have not all charged customers in the same way.
Supplier size matters
The ECO scheme was primarily funded by larger energy suppliers. Many smaller or newer suppliers did not include these costs in their tariffs.
This means:
- Customers of suppliers that previously charged ECO costs may see a larger visible reduction
- Customers whose supplier never passed on these charges may see a smaller saving, because there is less to remove from their bill
Tariff type also plays a role
Households on different tariff types may experience the changes differently:
- Standard variable tariffs are more likely to reflect changes automatically
- Fixed-rate deals may not show immediate reductions if policy costs were already priced in when the tariff was agreed
As a result, two households with similar energy use could see noticeably different bill reductions.

Who Is Likely to Benefit Most?
The largest relative savings are expected for households that:
- Are supplied by larger energy companies
- Are on standard variable or price-capped tariffs
- Use energy close to the national average, particularly electricity
Households that may see smaller reductions include those on long-term fixed deals with smaller suppliers, or those whose bills already excluded certain policy costs.
What the Changes Do Not Affect
It is important to understand what these reductions do not cover.
They do not:
- Protect households from changes in wholesale energy prices
- Eliminate standing charges
- Guarantee a fixed bill reduction for every household
Your final bill will still depend on energy usage, payment method, regional charges, and wider market conditions.
What Households Should Do Next
With changes arriving in 2026, households may benefit from taking a more active approach to managing their energy bills.
This includes:
- Reviewing current tariffs ahead of renewal dates
- Comparing how different suppliers structure policy and standing charges
- Checking energy statements carefully once changes take effect
Understanding how your bill is built up makes it easier to spot unexpected charges or identify situations where you may have paid more than necessary.
Key Takeaway
The planned energy bill reductions represent a genuine shift in how certain costs are funded, but the benefits will not be evenly distributed.
While some households will see savings close to the headline figure, others may receive less depending on their supplier and tariff structure. Knowing where your savings come from and how your bill is calculated is the best way to understand whether you are benefiting fully from the changes.
