The price cap will rise by £190 for a typical UK household from October, the fourth increase in two years. Ofgem confirmed the figure to the Daily Express earlier this week, as reported by the Daily Express. For a 3-bed semi using 12,000 kWh of gas and 2,900 kWh of electricity, that’s about £16 extra a month, or a third of a weekly food shop.
Who qualifies, and who doesn’t
The £190 figure applies to households on standard variable tariffs. Those on fixed deals, prepayment meters, or Economy 7 may see different numbers. Ofgem’s cap covers standing charges and unit rates, but not your actual usage. If you heat with oil or LPG, you’re outside the cap entirely, and prices there have been volatile too. The catch is that the cap is a ceiling, not a target. Many suppliers price below it, but switching is harder now than in 2021: only a handful of firms offer competitive fixes.
What it costs a typical 3-bed semi
Take a semi-detached house in Manchester with an EPC rating of D. Annual bills under the new cap will hit roughly £1,830. That’s £190 more than last winter, and £450 more than two years ago. The Energy Saving Trust estimates that loft insulation (top-up from 100mm to 270mm) costs £300-£400 and saves £180 a year. Cavity wall insulation runs £450-£700 and saves £200-£300. A-rated double glazing for a 3-bed semi costs £4,000-£7,500 but cuts heat loss by 20%, saving £100-£150 annually. The maths is brutal: without upgrades, the £190 increase is a permanent drain. With them, you claw it back in 2-3 years.
Grants that still pay
The Great British Insulation Scheme offers free or subsidised loft and cavity wall insulation for households with an EPC rating of D or below and living in council tax bands A-D in England. The Boiler Upgrade Scheme gives £7,500 off a heat pump installation, enough to cover most of the cost for a typical 3-bed semi. But officials have not confirmed when applications reopen for 2025 rounds. The Energy Company Obligation (ECO4) targets low-income homes and can fund whole-house upgrades. Check eligibility on gov.uk before October, waiting until the cap hits means paying the higher rate while your application processes.
What you should do now
Book an EPC assessment if you haven’t had one in 10 years, it costs £60-£120 but unlocks grant eligibility. Compare quotes from three MCS-certified installers for insulation or a heat pump. Switch to a fixed tariff if you can find one within 10% of the cap, MoneySavingExpert’s Cheap Energy Club updates daily. And if you’re on a prepayment meter, ask your supplier about moving to a smart meter to access cheaper rates. The £190 rise is real, but it’s not inevitable that you pay it in full.
Frequently Asked Questions
No. The £190 figure is based on a typical household using average amounts of gas and electricity. Actual changes depend on your tariff, meter type, and consumption. Prepayment and Economy 7 customers may see different amounts.
Possibly, but options are limited. A few suppliers offer fixed tariffs below the cap, but most are within 5-10% of it. Use comparison sites to check, but factor in exit fees if you switch from a fix. Insulation upgrades offer a more reliable long-term saving.
