Ofgem will raise the energy price cap to £1,862 from 1 October 2025, the third increase this year and £63 more than the current cap of £1,799. For a typical 3-bed semi using 11,500 kWh of gas and 2,700 kWh of electricity, that means an extra £5.25 a month. Small as it sounds, it compounds: the cap has climbed £350 since July 2023.
As reported by Rest Less, the rise reflects higher wholesale gas costs and increased network charges. The catch is that network charges alone add roughly £24 to a typical electricity bill, a cost that falls on every home, regardless of how efficient it is.
Who pays the most, and who can escape
Households on standard variable tariffs will see the full £63 hit. Prepayment meter customers pay a similar amount, though the cap is slightly lower due to cheaper payment methods. Those on fixed deals, which are rare now, are shielded until their contract ends. But the real divide is between homes with good insulation and those without. A draughty 3-bed semi loses up to 25% of its heat through the loft and walls. Loft insulation, £300–£400 installed, according to Energy Saving Trust, can save up to £285 a year at current prices. That’s a payback of 14 months. Cavity wall insulation costs £500–£1,000 and saves £200–£300 annually. For the cost of one year’s cap rise, you can cut your heating bill by a quarter.
Heat pumps and solar: the long game
The price cap rise makes heat pumps more compelling. A typical air-source heat pump costs £12,000–£15,000 installed, but the Boiler Upgrade Scheme (BUS) offers £7,500 off from 1 April 2025. Running costs are 20–30% lower than a gas boiler at current gas and electricity prices, says the Energy Saving Trust. That’s about £150–£225 saved a year on a typical bill. Solar panels, £5,000–£8,000 for a 4kW system, generate around 3,500 kWh annually, offsetting about 40% of a household’s electricity use. At the current cap rate of 24.5p per kWh, that’s £857 saved a year. Both upgrades lift an EPC rating from D to C or even B, which can add 2–5% to a home’s value, according to Nationwide data.
What the cap doesn’t cover, and what you can do now
The cap applies only to unit rates and standing charges, not to total bills. If you use more energy, you pay more. Typical usage is the baseline, but many homes use 15,000 kWh of gas. For them, the cap rise is closer to £80. The government’s Great British Insulation Scheme offers free or discounted insulation for low-income households. Eligibility runs through March 2026. For others, the simplest step is to draught-proof windows and doors, £50–£100 in materials, saving £60–£100 a year. A smart thermostat (£150–£250) can shave another £50–£70 off. The October cap rise is a nudge, not a crisis. But for homeowners who act, it’s a £63 signal to invest in upgrades that pay back faster than the next cap review.
What to do by when: Check your EPC rating at gov.uk. If it’s D or below, book a loft insulation survey before winter. Apply for the BUS grant before 31 March 2026. For solar, get quotes from three MCS-certified installers, lead times are 6–8 weeks. The cap rises on 1 October. Start now.
Frequently Asked Questions
Yes, standing charges are included in the cap calculation. They typically run 50p–60p per day for electricity and 25p–30p for gas, adding £270–£330 a year to every bill regardless of usage.
Fixed deals are currently 10–15% above the cap, so they’re rarely worth it. Check comparison sites for any offers below £1,862, if you find one, lock it in. Otherwise, stay on the cap and invest in efficiency.
