Energy Price Cap History 2021–2026: Every Quarterly Change

Quick answer: The Ofgem price cap for July–September 2026 puts a typical dual-fuel bill at £1,862 a year — a 13% rise on the spring. That is 46% higher than the £1,277 cap of winter 2021/22, but 56% below the £4,279 peak set for January 2023, when the government’s £2,500 Energy Price Guarantee shielded most households.

The energy price cap has been on a rollercoaster since 2021: a gas-supply crisis, a wartime spike, a government bail-out, and three years of uneasy settling. Here is every cap level from 2021 to today, with sources, in one table — and what each lurch tells us about where bills go next.

Every price cap level, 2021 to 2026

Figures are Ofgem’s typical annual dual-fuel bill for a household paying by Direct Debit. Until late 2022 the cap changed every six months; since January 2023 it has changed quarterly.

*From late 2023 Ofgem reduced its typical-consumption assumptions (now 11,500 kWh of gas and 2,700 kWh of electricity a year), so headline figures either side of that point are not perfectly comparable.

A quick refresher: what the cap actually caps

The price cap launched in January 2019 at £1,137 for a typical household, created to stop suppliers overcharging customers who never switched. Crucially, it caps the unit rates and standing charges a supplier can charge on a standard variable tariff — not your total bill. The “typical annual bill” figures in the table above are illustrations based on Ofgem’s assumed average consumption; use more energy and you pay more. Our full price cap explainer covers the mechanics in detail.

2021–2023: the crisis years

The cap entered 2021 at £1,138. In August 2021 Ofgem announced a £139 rise driven by record wholesale gas prices — the first tremor of the crisis. Russia’s invasion of Ukraine then sent the April 2022 cap up 54% to £1,971, and by October 2022 it stood at £3,549. The cap peaked at £4,279 for January–March 2023, though the Energy Price Guarantee meant a typical household actually paid around £2,500 from October 2022 until mid-2023.

2023–2025: settling, but never settled

From July 2023 the cap fell back below the guarantee level and spent two years oscillating between roughly £1,568 (summer 2024 — the post-crisis low) and £1,849 (spring 2025). What changed underneath: standing charges and network costs took a growing share of the bill even when the unit rates eased.

2026: a £117 fall, then a £221 jump

April 2026 brought a 7% cut to £1,641, which Ofgem attributed to government changes to environmental scheme funding (worth about £150 a year), cheaper wholesale energy (−£38), partly offset by higher network investment costs (+£66). Then July 2026 swung the other way: a 13% rise to £1,862, which Ofgem attributed to higher wholesale gas prices caused by the ongoing conflict in the Middle East. Under the current cap, electricity costs 26.11p per kWh (57.19p/day standing charge) and gas 7.33p/kWh (29.04p/day) for a typical Direct Debit customer.

What five years of cap history teaches

• The cap is a ceiling on unit rates, not on your total bill — using less energy is the only guaranteed way to pay less.
• Volatility is now normal: four of the last six quarterly changes have moved bills by 2–13% in either direction.
• Bills remain structurally higher than pre-crisis: July 2026’s £1,862 is 46% above the winter 2021/22 cap.
• Reducing exposure — through insulation, solar panels or a heat pump — is the one lever households control; our calculator estimates what each could save at current cap rates.

FAQs

What is the highest the energy price cap has ever been?

£4,279 a year for a typical household, set for January–March 2023. Most households did not pay that: the government’s Energy Price Guarantee limited a typical annual bill to around £2,500 from October 2022 to June 2023.

Why did the price cap rise in July 2026?

Ofgem attributed the 13% rise to £1,862 to higher wholesale gas prices caused by the ongoing conflict in the Middle East. Gas unit rates rose considerably more than electricity — around 24% versus roughly 5% quarter on quarter.

Is energy cheaper now than during the crisis?

Yes — a typical bill of £1,862 (July–September 2026) is 56% below the January 2023 peak cap and about 25% below the £2,500 households typically paid under the Energy Price Guarantee. But it remains 46% above the winter 2021/22 level, so bills have not returned to pre-crisis norms.
