The energy price cap will rise by £203 from 1 October, the third increase in 12 months. For a typical household paying by direct debit, annual bills will hit £1,971. Prepayment meter customers, already on the highest rates, will see a £214 jump to £2,077.
As reported by The Sun, the rise is driven by higher wholesale gas prices and increased network costs. But the headline figure masks a worse reality: standing charges, which households cannot reduce by using less, also rose by 2% in April and are set to rise again.
Who pays the most, and why
The cap applies to 28 million households on standard variable tariffs. But it is not a cap on your total bill, it caps the unit rate and standing charge. Use more, pay more. Use less, save less than you’d expect because standing charges now account for £334 a year on a typical dual-fuel bill.
Ofgem data shows prepayment customers pay the highest standing charges, about 11% more than direct debit households. The poorest households, who are disproportionately on prepayment meters, therefore face the steepest increases. Energy UK, the trade body, has called for a social tariff to protect vulnerable customers. The government has not committed to one.
Three upgrades that cut your bill and your EPC
A higher EPC rating, from D to C, can reduce annual heating costs by roughly 20–30%, according to Energy Saving Trust modelling. The three most cost-effective upgrades for a typical 3-bed semi are:
- Draught-proofing: Gaps around windows, doors and floorboards can lose 15–25% of heat. Professional draught-proofing costs around £200–£400 and saves £125–£250 a year. This is the single fastest payback of any home upgrade.
- Loft insulation top-up: Many UK homes have 100mm of loft insulation when 270mm is the current standard. Topping up to 270mm costs about £300–£500 and saves £50–£100 a year. EPC impact: up to two bands.
- Smart heating controls: A smart thermostat with room-by-room zoning can cut gas use by 10–15%. Typical cost £150–£300 installed. Payback in 1–2 winters. No planning permission needed.
What the government is not telling you
The Great British Insulation Scheme, launched in 2023, has installed measures in only 32,000 homes as of June 2025, far below the 300,000 target. The Boiler Upgrade Scheme offers £7,500 toward a heat pump, but take-up remains low because households must first improve insulation to make the heat pump efficient. The catch: no grant covers that insulation work.
Meanwhile, the Energy Price Cap is reviewed every three months. The next announcement, due in November, will set the January 2026 cap. Analysts at Cornwall Insight predict a further 4–6% rise if wholesale gas prices stay elevated. Households on fixed tariffs can lock in rates now, several suppliers are offering fixes at 10–15% below the October cap. Compare deals on a comparison site, not through your supplier’s default renewal.
What to do before winter
Check your current tariff. If you are on a standard variable, switch to a fix now, most have no exit fees and can be cancelled if a cheaper deal appears. Book a draught-proofing survey before September, when installers get busy. If your loft insulation is below 270mm, buy the rolls from a builders’ merchant and lay them yourself: it is a one-person weekend job.
Households on income-related benefits or with a child under five can apply for the Warm Home Discount, a £150 rebate on electricity bills. Applications open in October. Check eligibility on gov.uk. For everyone else, the cheapest kWh is the one you do not use. Draught-proof, zone your heating, and fix the tariff. That is the only way to beat a cap that keeps rising.
Frequently Asked Questions
Ofgem reviews the cap every three months. The next review in November 2025 will set the January 2026 cap. Analysts at Cornwall Insight predict a further 4–6% rise if wholesale gas prices stay high. A fall is possible if global gas markets ease, but no major price drop is forecast before spring 2026.
The Boiler Upgrade Scheme gives £7,500 toward a heat pump, but installers will typically require loft and cavity wall insulation to be at current standards before fitting. No separate grant covers that insulation work. You can use the Great British Insulation Scheme for insulation, but only if you meet the income criteria.
