Ofgem Energy Price Cap July 2026: What Changes from 1 July

TL;DR: Ofgem announced the July 2026 default tariff cap on 28 May 2026. The cap for typical dual-fuel direct debit households takes effect 1 July 2026 and runs to 30 September 2026. Cap levels are set quarterly and include unit rates and standing charges that vary by region and payment method. Customers on fixed-rate tariffs are not affected by the cap; only those on standard variable tariffs.

Ofgem Price Cap Timeline (2025-26)

Cap announcements verified via Ofgem's quarterly publications. The "typical" figure assumes a household using 2,700 kWh of electricity and 11,500 kWh of gas annually with dual-fuel direct debit payment.

What the July 2026 Cap Will Reflect

Ofgem sets the cap based on wholesale energy costs over a defined assessment window (the "observation period"). The July 2026 cap will reflect wholesale prices observed roughly mid-February through mid-May 2026. Wholesale gas prices in this window have averaged 75-90 pence per therm (Ofgem wholesale data, May 2026), broadly similar to the equivalent period for the April 2026 cap.

Forward markets in early May 2026 imply the July cap will be approximately 1-3% lower than the April cap of £1,690. This forecast is preliminary and subject to wholesale market movements during the remainder of the observation window. Ofgem's official announcement on 28 May 2026 will confirm the actual figure.

How the Cap Differs by Region and Payment Method

The "typical dual-fuel direct debit" headline figure is a national average. Actual cap levels vary by region (14 distribution areas) and payment method (direct debit, prepayment, standard credit). Households on prepayment meters typically pay similar rates to direct debit since the prepayment premium was largely removed in 2024. Standard credit (paying on receipt of bill) attracts the highest cap level, typically £40-80/year above direct debit.

Northern Scotland (region 1) has the highest unit rates due to higher distribution costs. London (region 5) has below-average unit rates but standard charges similar to other regions. Eastern (region 4) tends to be cheapest overall.

Fixed-Rate Tariffs Below the Cap

As of May 2026, several fixed-rate tariffs from major suppliers price below the prevailing cap: Octopus Energy 12-month fix at approximately £1,605/year (typical), British Gas Fixed at £1,650/year, EDF Essentials Fixed at £1,635/year. Customers comparing should check exit fees (typically £50-100 per fuel for early termination) and whether the fix is for 12 or 24 months.

Customers on fixed tariffs are protected from cap increases but also do not benefit from cap decreases. Moving from a fix to a standard variable tariff may be advantageous if the cap is expected to fall further; remaining on the fix may be advantageous if the cap is expected to rise.

FAQ: Ofgem Price Cap July 2026

When does the next price cap take effect?

The Ofgem default tariff cap for 1 July to 30 September 2026 will be announced on or around 28 May 2026 and takes effect from 1 July. The October 2026 cap will be announced in late August.

Does the price cap limit my actual bill?

No. The cap limits unit rates and standing charges per kWh and per day, but actual bills depend on consumption. A high-consumption household will pay more than the "typical" headline figure; a low-consumption household will pay less. The cap reduces the rate per unit, not the total bill.

Can suppliers charge above the price cap?

No. Suppliers are legally prohibited from charging customers on standard variable tariffs more than the prevailing cap rates for unit rates and standing charges. Fixed-rate tariffs are not subject to the cap and can charge any rate the customer agrees to at the point of contract.
