The October Energy Price Cap: What It Actually Means for Your Bill

From 1st October 2026, the energy price cap rises by 4%, but the headline £1,723 figure is not a maximum household bill.

The cap limits unit rates and standing charges on standard variable tariffs; what you pay still depends on how much energy you use.

You may have seen headlines saying that the energy price cap is changing again in October. But what does that actually mean for the amount you pay?

From 1st October to 31st December 2026, Ofgem’s energy price cap will rise by 4%. For a typical household using gas and electricity and paying by Direct Debit, the headline annualised figure rises from £1,663 to £1,723.

That does not mean your bill will be exactly £1,723. Here is what the cap really means.

What is the energy price cap?

The energy price cap is set by Ofgem, Great Britain’s energy regulator. It limits the maximum rates suppliers can charge customers on standard variable or “default” tariffs.

Ofgem reviews the cap every three months. Rather than putting one fixed limit on your total bill, it controls the price of each unit of energy and the daily standing charge.

Does the energy price cap limit my total bill?

No. The £1,723 figure is based on the energy use of a typical dual-fuel household paying by Direct Debit. It shows whether prices are moving up or down, but it is not a spending limit.

If you use more gas or electricity than the typical household, you can pay more. If you use less, you may pay less. Costs can also vary depending on where you live, how you pay and your meter type.

What are the October energy price cap unit rates?

A unit rate is the amount you pay for each kilowatt hour, or kWh, of gas or electricity you use.

A standing charge is a daily amount you pay for being connected to the energy supply, even when you use no energy that day.

From 1st October, average Direct Debit rates under the cap will be 26.32p per kWh for electricity, with a 54.83p daily standing charge, and 7.97p per kWh for gas, with a 29.68p daily standing charge. Exact rates vary by region, meter and payment method.

Does the price cap apply to everyone?

No. The cap mainly protects households on standard variable tariffs, whether they pay by Direct Debit, standard credit or prepayment. It also covers customers on tariffs such as Economy 7 where applicable.

If you are on a fixed tariff, the October cap change will not automatically change your agreed rates. The domestic cap also does not cover business energy contracts, heating oil or heat networks.

What should I look for on my energy bill?

Start with the name of your tariff and whether it is fixed or variable. Then check your electricity and gas unit rates, daily standing charges and meter readings.

Look to see whether readings are actual or estimated. If you pay by Direct Debit, check whether your monthly payment still reflects your expected use. Your Direct Debit is a payment arrangement, so it may not move by exactly the same percentage as the price cap.

Should I submit a meter reading before the change?

If you have a traditional meter, taking a reading on or around 30th September can help make sure energy used before and after the change is billed against the right rates. Keep a photo and submit the reading using your supplier’s preferred method.

If you have a working smart meter sending readings automatically, you should not usually need to submit an extra manual reading. Smart meters send information to suppliers so they can bill you accurately. If you are unsure whether yours is communicating correctly, check your latest bill or contact your supplier.
