The most a supplier can charge on a default tariff in this region, for each way of paying, with the Great Britain Direct Debit average for comparison. Electricity figures are for single-rate meters.

London: cap rates by payment method, 1 October to 31 December 2026
Payment method	Electricity unit rate (p/kWh)	Electricity standing charge (p/day)	Gas unit rate (p/kWh)	Gas standing charge (p/day)	Typical annual cost (Taupia's arithmetic)

Rates are Ofgem's, rounded to two decimal places as it publishes them. Gas rates include 5% VAT; electricity carries no VAT from 1 October 2026 to 31 March 2027. The London rows are Ofgem's figures for London.

Typical annual costs are Taupia's arithmetic: 2,500 kWh of electricity and 9,500 kWh of gas a year, Ofgem's current typical consumption, priced at each set of rates with a standing charge for every day of the year. Ofgem publishes one national headline per cap, not one per region.

What these rates mean for a typical bill in London

At Ofgem's typical consumption, electricity in London comes to about £822 a year: 2,500 kWh at 26.60p plus 365 days at 42.92p. Gas comes to about £884: 9,500 kWh at 8.15p plus 365 days at 30.20p. That is about £1,706 a year by Direct Debit, £18 less than the Great Britain average of about £1,724 by the same arithmetic.

Paying by standard credit costs more because both its rates and its standing charges are higher: about £1,839 a year here at typical use. A prepayment meter comes to about £1,662. Your own bill depends on your usage, meter and tariff, and a fixed tariff sits outside the cap altogether.

For comparison, the same arithmetic on the Great Britain average Direct Debit rates gives £1,724. Ofgem's published headline for October to December 2026 is £1,723 a year on its current typical-use measure, or £1,935 on the previous consumption basis used in the cap-history chart. The published rates are rounded, so the arithmetic lands within a pound of Ofgem's figure.

Assumptions behind these figures

2,500 kWh of electricity and 9,500 kWh of gas a year: Ofgem's current Typical Domestic Consumption Values.
A standing charge for each of 365 days, at the rates for the whole year.
Single-rate electricity. Multi-rate meters such as Economy 7 have their own capped rates on Ofgem's page.
A default tariff. A fixed tariff keeps the rates in its contract whatever the cap does.

Frequently asked questions

What is the energy price cap in London for October to December 2026?

For 1 October to 31 December 2026, a default tariff paid by Direct Debit in London is capped at 26.60p per kWh for electricity with a 42.92p daily standing charge, and 8.15p per kWh for gas with a 30.20p daily standing charge. At Ofgem's typical consumption that comes to about £1,706 a year by Taupia's arithmetic. The cap limits the rates, not the total bill, so using more energy costs more.

Why is the standing charge in London lower than the national average?

The Direct Debit electricity standing charge here is 11.91p below the Great Britain average of 54.83p a day. Ofgem sets a separate maximum for each distribution region and says it reflects how many people live in the region, how much energy the region uses on average, the amount of energy the supplier needs to buy and the cost of building and improving the network. UK Power Networks runs the electricity network in this region.

Do these rates apply if I am on a fixed tariff?

No. The cap applies to default tariffs, including the one a home is supplied on when nobody has chosen a deal. A fixed tariff keeps the unit rates and standing charges in its contract for the whole term. To compare a fix with the cap, price both on your own annual usage rather than on a typical household.

I am moving into a home in London. Which rates will I pay?

Until you choose a tariff, the existing supplier bills you on its default tariff, and the cap limits that to the rates on this page for the way you pay. Ofgem says you can choose a new tariff or supplier after you have moved in, and a standard variable tariff has no exit fee. Take a meter reading on the day you move in so your bill starts from your own usage.

When do these rates change?

The rates on this page are for 1 October to 31 December 2026. Ofgem publishes the January to March 2027 cap and its regional rates on 25 November 2026.
