The UK energy price cap: what it does and does not cover

Ofgem (the energy market regulator) sets a price cap on energy every three months. It is one of the most misunderstood numbers in Britain: many people assume it caps their total bill. It does not. Here is what the cap actually limits, what it does not, and why the famous "typical household" figure is not your personal ceiling.

What is the Ofgem price cap, and what does it not do?

The cap is the maximum your supplier can charge for a unit of energy and the standing charge together. It limits the unit rate (the price per kilowatt hour) and the daily standing charge — not the size of your bill.

For the period covering 1 October to 31 December 2026, the cap is £1,723 a year for a typical household paying by Direct Debit. That figure is only illustrative. It shows what a home with "typical" usage would pay and helps you compare tariffs, but it is not a ceiling on your personal bill.

Does the cap limit my total bill?

No. Ofgem is explicit that the cap does not limit the cost of your total bill. The more energy you use, the more you pay — there is no upper limit on the bill itself. The cap holds down the price per unit, but your total depends on how much you use, so £1,723 a year is not a maximum you will be charged. Use more, and your bill is higher.

The current rates under the cap (average across England, Scotland and Wales, paying by Direct Debit) are:

• electricity — 26.32 pence per kWh plus a 54.83 pence daily standing charge;
• gas — 7.97 pence per kWh plus a 29.68 pence daily standing charge.

What is a standing charge?

A standing charge is a fixed daily amount for being connected to the network. Ofgem says it applies even if you do not use any energy on that day. It sits inside the cap alongside the unit rate, and it varies by region, so the amount — and the final bill — differs across the country.

How often does the cap change, and who does it cover?

Ofgem reviews the cap every 3 months, so the figure you see today can rise or fall a quarter later. The cap does not fix a price forever; it tracks the wholesale energy market.

It protects customers on a standard variable tariff — the default tariff whose unit rate moves with the energy market. It applies in England, Scotland and Wales. It does not cover fixed tariffs, business contracts, heat networks or heating oil.

Can a fixed deal beat the cap?

Yes. Because the cap only protects people on a variable tariff, suppliers offer fixed deals that lock a price for a set term. A fixed deal can come in below the cap — but you give up the cap's protection if the market falls.
