Energy Price Cap UK Guide (Current Rate, History, How It Affects You 2026)

What Is the Energy Price Cap?

The energy price cap is a limit on the price per kilowatt hour (kWh) of gas and electricity that suppliers can charge customers on default tariffs. It was introduced by Ofgem in January 2019 to protect consumers from being overcharged. The cap does not limit your total bill — it limits the unit rates you pay for each kWh of gas and electricity and the daily standing charge. Your total bill depends on how much energy you use. The cap applies to customers on standard variable tariffs (SVTs) — the default tariff you are placed on when your fixed-term deal ends or if you have never switched supplier. As of 2026, approximately 28 million UK households are on SVTs or default tariffs covered by the cap. The cap does not apply to customers on fixed-term tariffs (though these are now generally priced close to or below the cap due to market conditions), prepayment meter customers (who have a separate prepayment cap), or economy 7 customers (who have a different cap reflecting their off-peak electricity rates). The cap is calculated using wholesale energy prices, network costs, operating costs, VAT (5% on energy), and a margin for suppliers (which has been reduced in recent years after the energy crisis showed that some suppliers were operating unsustainable business models).

Current Price Cap Rate (April–June 2026)

As of April 2026, the energy price cap for a typical dual-fuel household paying by direct debit is set at approximately £1,690 per year (down from £1,738 in Q1 2026 and significantly below the peak of £4,279 in Q1 2023). This figure assumes typical consumption of 11,500 kWh of gas and 2,700 kWh of electricity per year. The unit rate for electricity under the cap is approximately 24.5p per kWh with a standing charge of 53p per day. The unit rate for gas is approximately 6.0p per kWh with a standing charge of 31p per day. These rates vary slightly by region (there are 14 regions in the UK with different network costs) and payment method (direct debit is cheapest, prepayment is slightly higher, standard credit is most expensive). The annual figure (£1,690) is a guide — if you use less energy, your bill is lower; if you use more, it is higher. The standing charge alone amounts to approximately £307 per year (electricity £193 + gas £114), representing about 18% of the typical bill. The price cap is reviewed quarterly (January, April, July, October) based on wholesale energy market prices, inflation, and network costs. The July 2026 cap is forecast to decrease further as wholesale gas prices continue to stabilise, but geopolitical factors and international energy markets remain unpredictable.

History of the Price Cap

The energy price cap has seen dramatic changes since its introduction. January 2019 — the cap was introduced at £1,137 per year for a typical dual-fuel household. October 2021 — the cap rose to £1,277 as wholesale gas prices began to rise. April 2022 — the cap jumped to £1,971 following Russia's invasion of Ukraine. October 2022 — the cap was set to rise to £3,549, but the government's Energy Price Guarantee (EPG) limited typical bills to £2,500. January 2023 — the EPG remained at £2,500. April 2023 — the EPG ended and the cap rose to £3,280. July 2023 — the cap fell to £2,074 as wholesale prices dropped. October 2023 — the cap fell again to £1,923. January 2024 — the cap increased to £1,928. April 2024 — the cap fell to £1,690. July 2024 — the cap fell to £1,568. October 2024 — the cap increased to £1,717. January 2025 — the cap increased to £1,738. April 2025 — the cap fell to £1,690. July 2025 — the cap fell to £1,622. October 2025 — the cap increased to £1,675. January 2026 — the cap increased to £1,738. April 2026 — the cap fell to £1,690. The cap has demonstrated significant volatility in response to global energy markets, though it has stabilised somewhat since 2024.

Standing Charges Explained

The standing charge is a fixed daily fee you pay for being connected to the energy grid, regardless of how much energy you use. It covers the costs of maintaining the grid, metering, and supplier operating costs. In Q2 2026, the average standing charge is approximately 53p per day for electricity and 31p per day for gas for direct debit customers. That means you pay around 84p per day — about £307 per year — before you use any energy. Standing charges have been controversial because they affect low-energy users disproportionately. A household that uses very little energy still pays the same standing charge as a high-energy user. Ofgem is consulting on reforming standing charges in 2026, potentially introducing options to reduce or remove the standing charge in exchange for higher unit rates. This would benefit low-energy users but increase costs for high-energy users. Some suppliers are beginning to offer zero-standing-charge tariffs as an alternative. However, for most households, the standard standing charge remains part of the price cap structure. The standing charge varies by region — households in Scotland, northern England, and parts of Wales typically pay higher standing charges due to higher network costs. You can check your current standing charge on your energy bill. If you are a low-energy user, comparing zero-standing-charge tariffs could save you money.

How the Price Cap Affects You

The price cap affects you differently depending on your tariff type. If you are on a standard variable tariff (SVT) — your unit rates and standing charges are capped at the Ofgem level. Your bill is determined by your energy usage. When the cap changes, your rates change automatically. You do not need to do anything — the supplier applies the new rates. If you are on a fixed-term tariff — the cap does not directly affect you until your fix ends. However, fixed tariffs are priced relative to the cap. In 2026, fixed tariffs are generally 5–10% below the cap, so switching to a fix can save you money. If you are on a prepayment meter — a separate prepayment cap applies, slightly higher than the standard cap (about £50–£100 more per year). If you are on Economy 7 — different unit rates apply for day and night electricity, with a separate cap. The price cap also affects standing charges, which you pay regardless of usage. If you are struggling with energy costs, check if you qualify for Warm Home Discount (£150 off electricity bills for eligible households), Winter Fuel Payment (for pensioners), or Cold Weather Payment (£25 per cold week for benefit recipients). Contact your energy supplier for hardship schemes or payment plan options. See our Reduce Energy Bills guide → for 20 practical ways to lower consumption.

FAQs

What is the current energy price cap in the UK?

As of April 2026, the price cap is approximately £1,690 per year for a typical dual-fuel household paying by direct debit. The electricity unit rate is capped at around 24.5p/kWh with a 53p/day standing charge, and gas at 6.0p/kWh with a 31p/day standing charge.

Does the price cap limit my total energy bill?

No. The cap limits the unit rates and standing charges, not your total bill. Your total bill depends on how much energy you use. The £1,690 figure is based on typical consumption — if you use more, you pay more; if you use less, you pay less.

How often does the energy price cap change?

Every three months (January, April, July, October). Ofgem reviews and updates the cap based on wholesale energy prices, network costs, and other factors. The cap can go up or down each quarter depending on market conditions.

Who sets the energy price cap?

Ofgem, the UK energy regulator, sets the price cap. It is reviewed and updated by the regulator's team of analysts using a methodology that considers wholesale costs, network costs, policy costs, operating costs, and a reasonable profit margin for suppliers.

Should I fix my energy tariff or stay on the price cap?

In 2026, fixed tariffs are generally 5–10% below the price cap, so fixing could save you money. However, if the cap falls further, you could end up paying more than SVT customers. Compare available fixes using comparison websites before deciding.
