| The Ofgem energy price cap fell to £1,641 a year for a typical dual-fuel direct debit household for Q2 2026 (April to June), a £117 reduction on the Q1 2026 cap of £1,758. The Q3 cap covering 1 July to 30 September is announced on 27 May 2026, with independent forecasts clustering around £1,849. That makes the current Q2 cap window a useful moment to lock in a fixed deal, claim any government schemes you qualify for, and tighten the parts of your usage that translate fastest to bill savings. This page covers practical actions in three groups: free changes, low-cost upgrades, and grant-funded measures. | ||||||||||||||||||||||||
Key facts April 2026 Ofgem Q2 2026 cap: £1,641/year typical dual-fuel direct debit (down £117 on Q1) | Electricity unit rate: 24.67p/kWh national average | Gas unit rate: 5.74p/kWh national average | Warm Home Discount: £150 bill credit for eligible households | Boiler Upgrade Scheme: up to £7,500 toward a heat pump | Next cap announcement: 27 May 2026 | ||||||||||||||||||||||||
What to watch on 27 May 2026 Ofgem announces the Q3 2026 energy price cap (covering 1 July to 30 September) on the morning of 27 May 2026. Mid-May 2026 forecasts from Sainsbury's Energy, Eco Experts and EDF cluster around £1,849 a year, a rise of around £208 (12-13%) from the current £1,641. If forecasts are correct, households on standard variable tariffs face a meaningful jump in bills from July. Competitive fixed deals available right now may be a useful hedge for the period covering July onward; the calculation changes depending on what Ofgem confirms on 27 May. The cap after that (Q4 2026) is scheduled for 26 August. | ||||||||||||||||||||||||

Tariff and supplier action | ||||||||||||||||||||||||
| Around 60% of UK households are on standard variable tariffs at the Ofgem cap. Below-cap fixed deals and cap-tracker products are both available from major and challenger suppliers. Which suits a household depends mostly on a view of where the cap is heading. With Q3 2026 forecasts pointing upward (announced 27 May 2026), a fixed deal at or near the current £1,641 cap level can lock in protection against a rise from July. The trade-off is that if the cap surprises to the downside instead, a fixed customer pays more than a cap-tracker would. | ||||||||||||||||||||||||

| Comparison sites and the Ofgem-accredited Energy Compare tool let you compare available tariffs against your actual usage. Compare based on annual consumption in kWh rather than the headline cap figure, as standing charges and unit rates both vary by supplier and region. | ||||||||||||||||||||||||

Average energy bills by property type 2026 | ||||||||||||||||||||||||
| The £1,641 cap headline assumes typical domestic consumption: 2,700 kWh of electricity and 11,500 kWh of gas a year. Actual usage varies significantly by property size, insulation level, occupancy and heating habits. The figures below give an indicative range at Q2 2026 cap rates. | ||||||||||||||||||||||||

Frequently asked questions | ||||||||||||||||||||||||
What is the single biggest saving I can make on my energy bill? For most households, the biggest single saving is locking in a competitive fixed tariff before the cap rises, which can be worth £100-£300 a year depending on the size of the cap movement. After that, reducing the thermostat by 1°C (worth around 10% of heating costs) and improving insulation in an uninsulated loft (worth up to £310 a year and free through the Great British Insulation Scheme for eligible households) are the two largest single-action savings. Are energy bills going up or down in 2026? The Q2 2026 cap (April to June) fell by £117 from the Q1 cap of £1,758 to £1,641. The Q3 cap covering 1 July to 30 September is announced on 27 May 2026; mid-May 2026 forecasts cluster around £1,849, which would be a rise of around £208 from the current Q2 level. Direction beyond Q3 is uncertain and depends on wholesale gas market movements. Should I fix my energy tariff now? A fixed tariff locks in unit rates and standing charges for the contract length, typically 12 or 24 months. If the Q3 cap rises as currently forecast (around £1,849), fixing at or near the current £1,641 cap level would save the difference over the period the cap is above the fixed rate. The risk is the opposite scenario where the cap falls further; a fixed customer would then pay more than a cap-tracker would. Some suppliers offer no-exit-fee fixed deals or cap-tracker products specifically designed for this uncertainty. Can I get free insulation from the government? Yes, through the Great British Insulation Scheme (loft and cavity wall insulation for properties in EPC bands D-G and council tax bands A-D in England, A-E in Scotland and Wales, subject to income or benefit criteria) and the ECO4 scheme (broader range of measures including heating, for low-income or vulnerable households). Apply directly through gov.uk or via your energy supplier. Some installers also operate the schemes on behalf of suppliers. Am I eligible for the Warm Home Discount? The Warm Home Discount (£150 credit on the electricity bill) is paid to two groups in England and Wales: the Core Group (households where someone receives Pension Credit Guarantee Credit) and the Broader Group (households on certain qualifying benefits whose property meets the high-energy-cost criteria, identified automatically from DWP data and energy supplier records). Scotland has a separate scheme. Most eligible households are identified and paid automatically; some may need to apply through their energy supplier. Can people with long-term medical conditions get help with energy bills? Households where someone has a long-term medical condition can register on the Priority Services Register (free, contact your energy supplier) for advance notice of power cuts, priority restoration, and free meter readings. The Warm Home Discount £150 credit is based on income and qualifying benefits rather than medical condition, but a medical condition may bring a household within the eligible benefits. Some local councils run additional discretionary support schemes for people with medical needs; check with your local authority. | ||||||||||||||||||||||||
