UK Energy Bills 2026: Ofgem Price Cap, Average Bills, and How to Cut Them

For a typical dual-fuel household using 11,500 kWh of gas and 2,700 kWh of electricity per year on a standard variable tariff paid by direct debit, the annual bill is approximately £1,849 in Q2 2025 — though this varies as the Ofgem price cap is reset every three months. Households using less pay less, larger homes pay more. Bills peaked at the £2,500 capped level in 2022-2023 and have fallen since but remain well above pre-2021 levels of £1,100-£1,300.

The Ofgem energy price cap is the maximum unit rate (pence per kWh) and daily standing charge that energy suppliers in England, Scotland and Wales can charge customers on standard variable tariffs. It is reset every three months by Ofgem based on wholesale energy costs and other supply chain factors. The cap does not limit the total bill — that depends on how much energy you actually use — and it does not apply to fixed-rate tariffs, which suppliers price freely. Northern Ireland has separate energy regulation with no equivalent cap.

Fix your tariff if a deal is available below the current cap with a reasonable exit fee. From late 2024 onwards a number of suppliers (Octopus, EDF, OVO, British Gas) have offered fixed deals between 5% and 15% below the cap, which guarantees savings if the cap rises and gives certainty against winter price increases. Stay on the cap if your bills are very low, you might switch suppliers, or no fix is available below the cap level.

Standing charges have risen sharply since 2022 to about 53p/day for electricity and 33p/day for gas — adding around £313 a year before you use any energy at all. The increases reflect three things: the costs of failed energy supplier rescues during the 2021-2022 wholesale price spike (Bulb, Avro, etc.), grid maintenance costs, and policy levies for renewable subsidies and warm home discounts. Ofgem is actively reviewing whether to reduce standing charges and shift more cost into unit rates, with consultation ongoing through 2025-2026.

Several support schemes exist in 2025-26: Warm Home Discount (£150 off your electricity bill, automatic for pension credit recipients and applied for by some low-income households); Cold Weather Payment (£25 a week during very cold periods for benefits recipients); Winter Fuel Payment (£100-£300, currently restricted to pension credit recipients only after 2024 changes); Household Support Fund administered by your local council; supplier hardship funds (most major suppliers run these — contact them directly); and the Priority Services Register if you have additional vulnerability, which gives extra protections.

Forecasts from analysts like Cornwall Insight suggest the price cap will continue to fluctuate quarterly through 2026 in a range broadly similar to 2025, with no expected return to pre-2021 prices. Wholesale gas markets remain elevated due to ongoing geopolitical factors and the loss of cheap Russian pipeline gas. The longer-term trajectory depends on global LNG prices, North Sea production, renewable build-out rates, and grid capacity. Most forecasters do not expect the typical dual-fuel bill to return below £1,500 a year before 2027 at the earliest.

Sometimes. A modern air source heat pump with a coefficient of performance (COP) of 3.5 produces 3.5 kWh of heat per 1 kWh of electricity. At Q2 2025 rates of 27p/kWh for electricity and 6.3p/kWh for gas, the heat pump effectively produces heat at 7.7p/kWh equivalent, versus 6.3p/kWh for a gas boiler. So heat pumps are slightly more expensive per unit of heat at current rates, BUT can be significantly cheaper if combined with a Time of Use tariff like Octopus Cosy or Agile that offers cheap off-peak electricity. The £7,500 government Boiler Upgrade Scheme grant makes the install economics much more attractive for many households.

In winter (October-March), the typical UK semi-detached house heated by gas central heating costs roughly £150-£250 a month for combined gas and electricity. In summer (April-September), the same house typically pays £40-£90 a month, mostly for electricity (cooking, lighting, appliances, water heating). The seasonality means most direct debit billing arrangements smooth payments to a steady ~£155 a month all year for a typical 11,500 kWh gas / 2,700 kWh electricity household on the price cap.
