Fixed energy deal savings of up to £173 a year are available right now for households willing to switch before the October 2026 price cap rise takes effect. With a second consecutive quarterly increase confirmed and analysts forecasting a third in January, the case for locking in a fixed rate has rarely been more straightforward.
The new cap, announced by Ofgem on 26 August 2026, takes the typical annual bill for the 22 million households on default variable tariffs to £1,723, based on updated consumption assumptions of 2,500 kWh of electricity and 9,500 kWh of gas per year. That is a 4% rise from the current quarter, following a 13% jump in July. In unit-rate terms, households on standard variable tariffs will pay 26.32 pence per kWh for electricity and a standing charge of 54.83 pence per day, on average across England, Scotland and Wales, and excluding VAT.
The driver is the wholesale gas market. Ofgem cited ongoing uncertainty over the US-Iran conflict as a primary factor pushing winter wholesale prices to their highest level in almost four years. Reuters reported that Cornwall Insight also pointed to shipping disruptions in the Middle East and reduced liquefied natural gas exports from Qatar, compounded by European heatwaves lifting demand across the continent.
What Fixed Energy Deal Savings Actually Look Like
The cheapest deal on the market at the time of writing is a Fuse Energy fixed tariff priced at £1,550 a year for a typical-usage home. That is £173 below the October cap and £113 below the current level. The deal comes in a 14-month version, Fuse Energy August 2026 Fixed (14m) V1, available through Uswitch and Confused.com as well as direct from Fuse Energy. MoneySuperMarket lists an 18-month variant, Fuse Energy August 2026 Fixed (18m) V10. Co-op Energy, Octopus Energy, E.ON Next and Ecotricity all have competing fixed deals offering typical savings of more than £100 a year against the October cap, according to the original research.
Ofgem itself has endorsed the logic, stating: ‘Savings are available by choosing a fixed tariff, which are available at £100 or more below the October price cap.’ About 11 million homes, 35% of the total, are already on fixed deals and will not feel October’s increase at all.
Before switching, check for exit fees on your current contract. Gareth Kloet at Go.Compare advises verifying how long remains before committing. Price comparison sites will generate personalised quotes based on your actual usage, which matters because the cap figure is calculated on typical consumption, not your own.
January Looks Worse, and the Next Announcement Is in November
The more pressing reason to move now is what comes next. Cornwall Insight forecasts a further 9% rise in January, which would push the typical bill to about £1,872 a year, a £149 increase. The consultancy’s detailed Q1 2027 projection puts the figure at £1,872.15, with electricity accounting for £910.58 and gas £961.57. These are forecasts, not confirmed figures. Ofgem will announce the January cap on 25 November 2026.
If that forecast proves correct, a household switching today to the cheapest available fixed deal would avoid both the October and January increases. The maths are not complicated: £1,723 rising to £1,872 on a variable tariff versus a locked-in £1,550. The gap widens with each passing quarter.
Context matters here. The cap peaked at £3,582 in July 2023, according to BBC News data, before falling to a low of £1,414 in July 2024. The current trajectory is running in the opposite direction again.
One policy detail worth understanding: the government’s VAT relief applies only to electricity, not gas. The zero rate runs from 1 October 2026 to 31 March 2027, delivering the £45 annual saving that has already been factored into the new cap figure. As MoneySavingExpert has pointed out, that saving is largely absorbed by the simultaneous cap increase for anyone remaining on a variable tariff. Fixed-deal customers will also receive the VAT relief automatically, so the discount stacks on top of whatever rate they have locked in.
Households that cannot switch, or who prefer not to, should check eligibility for the warm home discount scheme, which reopens in October and provides a one-off £150 credit against electricity bills. Smart meter customers may also find cheaper off-peak tariffs worth asking suppliers about.
The January announcement on 25 November is the next forcing function. By that point, the cheapest fixed deals available today may be gone.
