Energy price cap rise trimmed but bills stay high for years

Ofgem will raise the energy price cap by roughly £63 in October, about half the increase forecast three months ago. The typical dual-fuel household on a standard variable tariff will now pay around £1,800 a year, not the £1,920 that analysts had predicted in June.

The revision follows a drop in wholesale gas prices, as reported by the Financial Times. But the regulator’s own data shows that network charges and policy costs, the bits of the bill households can’t shop around for, have risen 12% since April alone.

What the cap change means for your January bill

The headline figure, £63 less than feared, is a genuine relief for the 11 million households on default tariffs. But the catch is that £1,800 a year is still roughly £600 more than the typical bill in winter 2020-21. The cap resets every three months, so the October change is temporary. January’s cap, based on summer wholesale prices, could nudge up again if global gas markets tighten.

For a 3-bed semi using 12,000 kWh of gas and 2,900 kWh of electricity, the October cap means the direct debit will fall by about £5 a month compared to the July forecast. That is not nothing, but it is not a return to normality either.

Who qualifies for help, and who doesn’t

The Warm Home Discount will reopen for applications in October, giving £150 off electricity bills for low-income households. Pensioners on Pension Credit can claim the Winter Fuel Payment, though the government has means-tested it this year. But the vast majority of working households on median incomes get no direct support. The £400 Energy Bills Support Scheme ended in March 2023, and there is no replacement.

What this misses is that the cap only limits the unit rate and standing charge, it does nothing to reduce the amount of energy a draughty home wastes. A semi-detached house with single glazing and 100mm loft insulation will still lose heat at roughly 6 kWh per hour on a cold January day, regardless of what the cap says.

Why the cap makes heat pumps and insulation more urgent

The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. At current prices, a heat pump can cut heating bills by 25-40% compared to a gas boiler, depending on the property’s heat loss. For a typical 3-bed semi, that means annual savings of £200-£350, enough to recover the upfront cost within 8-10 years, even after the grant.

Loft insulation topping up from 100mm to 270mm costs about £300-£400 and can save £150-£200 a year. Cavity wall fill, where suitable, runs £400-£600 and saves a similar amount. Those are not trivial sums, but they are investments that pay back within two to four winters, and they insulate the household from future cap rises.

What to do next

Households on standard variable tariffs should check their direct debit before October. If the cap is lower than the current payment, the supplier must reduce it or refund the credit. Compare the new rate against fixed deals, some one-year fixes are now below £1,750, though they carry early exit fees. For those with an EPC rating below C, the quickest win is a free or subsidised home energy assessment through the Energy Saving Trust. That assessment will flag the cheapest measures, often draught-proofing and LED upgrades, before the winter heating season begins.

The price cap is a safety net, not a strategy. The only way to bring bills down permanently is to stop the heat from leaving the house in the first place.
