Ofgem has confirmed an energy price cap level taking effect on October 1, 2026, according to the confirmation dated September 12. Households on tariffs covered by the cap should check their supplier’s October prices and payment notice before adjusting their winter budget.
The confirmation does not include the new annual benchmark, percentage change or individual gas and electricity rates. It therefore does not establish whether bills will rise or fall, or by how much. A precise monthly increase or saving cannot responsibly be quoted from it.

Which October prices affect your household?
Ofgem’s domestic price cap applies to standard variable tariffs in England, Scotland and Wales; Northern Ireland has separate arrangements. The cap limits energy rates rather than placing a ceiling on your total household bill. Your consumption still determines how much you pay.
Check these figures in your supplier’s notice:
| Cost to check | Why it matters |
|---|---|
| Electricity and gas unit rates | These determine the charge for each kilowatt-hour used. |
| Daily standing charges | These apply even on days when you use no energy. |
| Estimated annual cost | This should reflect your household’s consumption. |
| Monthly direct debit | This is a payment towards your account, rather than a capped monthly bill. |
Rates can differ by region, payment method and meter arrangement. Even when an average annual benchmark is available, dividing it by 12 will not necessarily reproduce your direct debit.
Check the calculation behind your direct debit
A supplier may consider expected consumption, account credit or debt and seasonal demand when reviewing payments. A percentage change in the national benchmark does not automatically mean the same percentage change in your monthly payment.
If your payment changes, ask which annual usage estimate and account balance support the calculation. Check those against recent statements before requesting an adjustment.
Before October 1, compare tariffs and record readings
Compare any fixed tariff using your actual annual gas and electricity consumption, including standing charges, contract length and exit fees. A fixed rate can provide price certainty, but it does not guarantee savings or fix your total bill regardless of usage.
For a manually read meter, take a dated photograph around September 30 and submit the reading through your supplier’s usual channel. This helps allocate consumption across the rate change. If you have a smart meter, check that readings are reaching the supplier.
Before October 1, check your supplier’s personalised notice alongside Ofgem’s energy price cap information for the applicable rates and annual benchmark.
Frequently Asked Questions
Does the October 2026 energy price cap mean my bill will go up?
The confirmation alone does not establish whether your bill will rise or fall. It gives an October 1 start date but no new benchmark or rates. Your household’s cost depends on the prices your supplier applies and how much energy you use. Before changing your budget, check that your tariff is covered and compare your supplier’s October unit rates and standing charges with your current ones.
How can I work out what the October prices will cost me?
Use your last 12 months of gas and electricity consumption in kWh and your supplier’s October rates. For each fuel, calculate (annual kWh × unit rate in pence + 365 × daily standing charge in pence) ÷ 100. Add the fuel totals, then repeat with your current rates to compare costs on the same usage. This is an annual illustration assuming those rates stayed unchanged—not a forecast of future prices. Dividing by 12 gives a budgeting average, but winter usage and your account balance can make your payments different.
What should I do if my new direct debit looks too high?
Ask your supplier for the calculation behind it. Request the annual consumption estimate, prices used, current credit or debt, and any amount included to clear a balance. Compare the usage estimate with your statements and check whether recent readings were actual or estimated. If something is wrong, provide an up-to-date reading where appropriate and request a revised calculation. If the amount is accurate but unaffordable, ask about payment support before missing a payment.
What should I check before the October 1 change takes effect?
Keep your supplier’s October price notice and check its effective date, tariff name, payment method and meter details against your account. If the notice is missing or unclear, request the applicable rates and a personalised cost estimate from your supplier. For the published cap figures and scope, consult Ofgem’s official energy price cap information. Until the missing rates are available, treat any precise monthly increase or saving as unverified.
