The energy price cap will rise by £63 from 1 October, pushing typical household bills to £1,717 a year. That is the third increase in 12 months, and it lands just as winter heating demand begins. For a country where 13% of homes already live in fuel poverty, this is not an inconvenience, it is a crisis.
As reported by the Big Issue, energy experts have issued a ‘red warning’ on fuel poverty, with up to 6 million households expected to cut back on heating this winter. The numbers are stark but the solutions are concrete.
Who qualifies, and who doesn’t
Ofgem sets the cap for default tariffs covering 29 million households. The rise reflects higher wholesale gas and electricity costs, plus network charges that have climbed 12% since 2022. But the cap is a ceiling, not a floor: 11 million households on fixed deals may pay less, while prepayment meter users face slightly different rates. The real divide is between those who can afford upgrades and those who cannot. Fuel poverty is defined as spending more than 10% of income on energy. At £1,717, a household earning £20,000 gross spends 8.6%, before any heating is turned on.
What it costs a typical 3-bed semi
Take a semi-detached home in Manchester, gas-heated, with cavity walls and loft insulation from 2010. Its annual bill will hit £1,717. But that assumes average consumption of 12,000 kWh gas and 2,900 kWh electricity. A draughty Victorian terrace using 18,000 kWh could pay £2,100. The Energy Saving Trust estimates that topping up loft insulation to 270mm saves £180 a year. Adding cavity wall insulation saves another £215. Combined, that nearly cancels the cap rise. Yet fewer than 30% of homes have adequate loft insulation, according to the latest English Housing Survey.
Grants, heat pumps and the bigger picture
The Boiler Upgrade Scheme offers £7,500 toward a heat pump. For a household currently on gas, the switch could cut heating bills by 20-30% depending on the property’s fabric. But the upfront cost after grant still runs £3,000-£5,000, out of reach for many. The Great British Insulation Scheme provides free or discounted insulation for low-income households, but take-up has been slow: only 120,000 homes upgraded in its first year versus a target of 300,000. The catch is that most grants target the poorest, leaving middle-income families to pay full price.
What this misses, the rental trap
But the price cap debate overlooks a structural problem: 4.5 million private renters cannot choose their heating system or insulation. Landlords must meet an EPC rating of E or above, but the minimum is set to rise to C by 2028. Until then, tenants in F- or G-rated homes face bills £700 higher annually. The government’s Warm Home Discount provides £150 off electricity bills for low-income households, but it does not address the root cause, leaky homes.
Households on standard variable tariffs should check their supplier’s cheapest fix before October. Those eligible for the Warm Home Discount can apply through gov.uk from mid-September. For owner-occupiers, a home energy assessment from the Energy Saving Trust costs £100-£200 and identifies the upgrades with the fastest payback. The price cap will rise again in January 2025, but your home’s efficiency does not have to.
Frequently Asked Questions
Yes, if you are on a standard variable tariff. Fixed deals are available from several suppliers, though rates have risen. Compare offers on Ofgem-accredited sites; a 12-month fix could save £50-£100 versus the cap.
Eligibility depends on your property's EPC rating and household income. Homes rated D or below, with a gross income under £31,000, may qualify. Check via gov.uk or your energy supplier.
