The price cap will rise by £221 a year from July, the fourth increase in 18 months. For a typical 3-bed semi using 12,000 kWh of gas and 2,900 kWh of electricity, that adds £18.42 to the monthly direct debit. Standing charges, which have risen 43% since 2021, now account for nearly £330 of the annual bill before a single unit is used.
As reported by The Independent, the announcement came alongside confirmation that the energy price guarantee will end in April. That means no further government support beyond the cap itself. Households on prepayment meters face an even steeper climb: their cap rises by £247.
Who pays the most, and why
The cap applies to standard variable tariffs, which 28 million households are on. Fixed deals have largely disappeared: the cheapest fix available today is 12% above the cap, according to data from comparison sites. But the cap is not a ceiling on total bills, it limits unit rates and standing charges. A household using more energy than the typical profile pays more than £221 extra.
Ofgem calculates the typical profile at 12,000 kWh gas and 2,900 kWh electricity. Yet the average 4-bed detached uses 17,000 kWh of gas. That household will see an increase closer to £310. The catch is that standing charges are rising faster than unit rates: the daily standing charge for electricity will hit 60p in some regions, up from 45p in 2022. That penalises low users, flats, small terraces, empty-nesters, who cannot reduce their fixed costs.
What it costs a typical 3-bed semi
Take a semi-detached house in Manchester with cavity-wall insulation, 200 mm loft insulation, and a gas combi boiler. Before the rise, the annual bill sat at £1,634 under the current cap. After July, it will be £1,855. The breakdown: £1,120 for gas, £735 for electricity. Standing charges add £329 to that total.
A household with an air-source heat pump and solar panels, by contrast, pays roughly £1,050 for electricity and heating combined, a saving of £805 a year. The upfront cost of a heat pump under the Boiler Upgrade Scheme is typically £2,500–£3,500 after the £7,500 grant. Solar panels for a 4 kW system cost around £5,000–£6,000 and generate savings of £300–£500 annually. The payback period on both upgrades is now under 8 years, thanks to rising unit rates.
What households can do before October
The first step is a home energy audit. The Energy Saving Trust offers a free online tool that identifies the biggest leaks. Loft insulation (cost typically £300–£400) cuts heat loss by 25% and pays back in under 2 years. Cavity-wall insulation (cost typically £500–£700) saves £200–£300 a year. Both are eligible for ECO4 grants if the household receives means-tested benefits.
Smart heating controls, thermostatic radiator valves, a smart thermostat, and a zoning system, reduce gas use by 10–15% for a typical install cost of £250–£500. The government’s Boiler Upgrade Scheme still has funding for this financial year, but applications take 8–12 weeks to process. Households on standard variable tariffs should apply through gov.uk from 4 November. Eligibility closes on 31 March 2027.
Frequently Asked Questions
No. The £221 figure is Ofgem's estimate for a 'typical' household using 12,000 kWh of gas and 2,900 kWh of electricity. Households that use more energy, larger homes, those with electric heating, will see a bigger increase. Those on prepayment meters face a £247 rise.
Fixed tariffs are still available but typically cost 10–15% more than the current cap. With the cap rising, a fix might break even by winter. Compare offers on Ofgem-accredited sites, but check exit fees, they can be £50–£75 per fuel.
