More than four million households on standard variable tariffs will see their energy bills rise from Thursday, 1 October, after Ofgem's price cap increased by 4%. The change adds about £5 per month, or £60 per year, to the average annual dual-fuel bill, pushing up costs as the heating season begins.
The regulator has responded by publishing three steps it says households can take to regain control of their energy spending. The advice is aimed at the millions of homes still on default standard tariffs, which are typically the most expensive plans offered by suppliers. Ofgem has urged consumers to act before the increase takes effect, although the cap itself sets a limit on unit rates and standing charges rather than a total bill.
The cap rise reflects higher wholesale energy costs and network charges, which suppliers pass through to customers. For a typical household, the £60 annual increase is modest compared with the volatility seen in recent years, but it still adds pressure to budgets already stretched by food, housing and transport costs. The increase applies automatically to standard variable tariffs, meaning affected households do not need to do anything to see the higher rates applied.
Ofgem's three steps focus on practical actions: reviewing current usage and tariff type, comparing available deals, and considering fixed-rate offers or efficiency measures. The regulator has repeatedly encouraged consumers to switch or renegotiate where possible, though the number of competitive fixed deals has narrowed in recent years. Households that take no action will remain on the capped standard tariff and absorb the full increase.
The timing is significant because the cap change coincides with the start of colder weather, when energy consumption typically rises. For households already struggling, the combined effect of higher unit rates and increased usage can be severe. Consumer groups have warned that the increase will hit those on lower incomes hardest, particularly pensioners and families with young children.
Looking further ahead, forecasts suggest the pressure may intensify. Analysts at Cornwall Insight predict the cap could rise by 16% from January, equivalent to an additional £276 a year for the typical dual-fuel household, taking the average annual bill to around £1,999. That would be the largest quarterly jump since January 2023. The forecast cites the ongoing impact of conflict in the Middle East, which has unsettled global energy markets and raised the cost of wholesale gas.
If those projections materialise, the January increase would arrive during the coldest months, compounding the strain on household finances. The government has not announced additional support for energy bills beyond existing schemes, though the regulator continues to monitor market conditions. Suppliers, meanwhile, are expected to pass through the higher costs, leaving consumers to decide whether to fix, switch or reduce consumption.
Ofgem's message is clear: acting early can limit the impact. The three steps are designed to be simple and accessible, but their effectiveness depends on whether households can find cheaper alternatives in a market where fixed deals remain limited. For the four million homes affected from Thursday, the immediate reality is a higher bill and a renewed call to take control of their energy costs.
