UK energy price cap to rise 4% to £1,723 in October as Middle East conflict drives costs

Cap increase and household impact

Energy regulator Ofgem announced on 26 August that the domestic price cap in England, Scotland, and Wales will rise by 4% starting 1 October. The adjustment lifts the benchmark dual-fuel bill for a typical household by £60 per year, or £5 per month, from £1,663 to £1,723. The increase directly applies to approximately 22 million households on standard variable tariffs, representing 65% of retail energy customers. An estimated 11 million households on fixed tariffs will not see immediate rate changes, as fixed contracts remain insulated from cap adjustments. Under the calculation methodology used by Ofgem before July, the equivalent annual rate would stand at £1,941, up from £1,862. Although the October figure marks the highest average level since July 2023, bills remain 52% below the 2022 peak of £2,500 during the Energy Price Guarantee.

Wholesale market pressures and government tax cuts

The upward revision follows persistent volatility in global wholesale gas markets, propelled by the military conflict in Iran and wider Middle Eastern instability. Elevated summer temperatures across Europe also contributed to gas consumption by driving electricity demand for indoor cooling and air conditioning. To soften the financial impact, Prime Minister Andy Burnham noted the government's decision to eliminate value-added tax on domestic electricity bills starting in October.

It's difficult for people and I recognise that. But it's why, within days of taking office, I announced that we would remove VAT off electricity bills to give people that little bit of help.

The VAT reduction reduces the annual price cap calculation by approximately £45. The tax relief keeps electricity costs broadly flat, leaving wholesale gas prices to drive nearly all of the headline increase. Gas charges will increase by 8%, whereas households relying exclusively on electricity face bill increases of less than 1%.

Political defense and consumer guidance

Appearing on Sky News on Wednesday morning, Energy Secretary Miatta Fahnbulleh defended the government's energy policy while pointing to foreign conflicts as the primary cost driver.

We're going to keep working to get bills down. What I can't control are wars in the Middle East that we weren't a part of, which impact families here.

Fahnbulleh noted that the VAT cut follows a £150 reduction in policy costs implemented earlier in the year. Speaking on Good Morning Britain, consumer champion Martin Lewis clarified that fixed-rate customers retain their contract pricing until expiry, while VAT reductions are applied automatically across all tariff types. Ofgem director general for markets Neil Kenward advised eligible customers to consider fixed deals priced £100 or more below the new cap, or to switch to prepayment meters, which average £45 less per year than standard direct debit plans.

Mounting sector debt and winter projections

Consultancy Cornwall Insight warned that costs will escalate further in early 2027, forecasting an additional 9% cap increase in January to £1,872 per year. French supplier EDF projected that household energy bills across Britain will stay at elevated levels until the end of the decade. Typical domestic bills remain 70% higher than pre-2021 levels, adding roughly £600 in annual expenses compared to pre-crisis baselines, according to trade body Energy UK. Unpaid energy debts past three months have climbed to record levels, with supplier bad debt reaching £6 billion and expected to touch £7 billion by December. Passing on debt-recovery costs currently adds £60 to each annual household bill, with consultancy Baringa forecasting that cross-subsidy burden to reach £100 per household by year-end.
