“Household energy bills to hit three-year high as Ofgem announces 4% rise from October”

What actually happened

Ofgem confirmed the energy price cap will rise from 1 October, taking the typical dual-fuel household bill to £1,723 a year if usage stayed constant. The rise is uneven: gas bills go up 8% while electricity bills fall slightly, a mix Ofgem's own press release and its markets director both describe using the rounded 4% figure. The government is offsetting the increase for some households via a VAT cut on electricity and a £150 Warm Homes Discount.

Key facts

• Cap rises £60/year (£5/month) to £1,723 for the average dual-fuel household, per "Based on the energy use of a typical domestic household, from October, the price cap will rise by £60 per year (or £5 per month) to £1,723 for the average household using both electricity and gas if this level was sustained for a year."
• Ofgem's own director general confirmed the real change is 3.6%, but the regulator rounds it to 4% for its headline figure.
• The rise is not uniform: gas bills up 8%, while electricity bills are "actually falling slightly" due to the government's VAT cut, per Ofgem's Neil Kenward.
• Only 22 million of the roughly 33 million UK households are on tariffs affected by the cap; 11 million (35%) are on fixed tariffs and unaffected.
• Cornwall Insight forecasts a further 9% rise in the new year, meaning October's number is not the winter peak.
• Ofgem lowered its "typical use" benchmark to 9,500 kWh gas / 2,500 kWh electricity a year, reflecting falling consumption, which shifts the denominator behind the headline figure.

What to watch for

Watch whether Cornwall Insight's forecast 9% January rise materialises, which would make the "three-year high" framing look conservative within months. Also watch coverage of the 3.6% vs 4% rounding: if a later story leans harder on the rounded figure to dramatise the story, that's the tell spin has crept in.
