The Ofgem price cap is set to change for July to September, with analysts predicting a rise driven by wholesale prices and energy infrastructure disruptions. This page answers the most common questions households have about the upcoming cap, who might be affected, and practical tips to manage costs as autumn approaches.
For July to September, Ofgem reviews the price cap to reflect wholesale energy costs. Early forecasts indicate a rise to around £1,850 a year for a typical dual-fuel household, though the exact figure will be confirmed by Ofgem. The cap limits how much standard variable and default tariffs can cost per year, influencing bills for households on default tariffs and those who haven’t switched.
Vulnerable groups—such as low-income households, those with long-term illnesses, and critical energy users—often feel the impact of price rises more. Government and energy sectors typically announce targeted support, including grants, rebates, or easier access to affordable tariff options. Check eligibility for schemes like bill assistance, energy-saving programs, and any autumn-fallback measures announced for vulnerable customers.
The price cap is tied to wholesale market costs. Higher wholesale gas and electricity prices, sometimes driven by regional tensions or disruptions to infrastructure, push the cap upward. While the cap doesn’t reflect every household’s exact usage, it sets a ceiling that influences most default tariffs and suppliers’ pricing decisions.
To curb costs, consider locking in a fixed tariff if predictable bills help you budget, compare and switch to a lower-rate plan if you’re on a variable tariff, improve home insulation and energy efficiency, and adjust thermostat settings and appliance use. Simple steps like reducing standby power, using smart meters, and efficient laundry/lighting habits can add up as prices rise.
Ofgem typically publishes the exact cap figure ahead of the quarter. While forecasts exist from bodies like Cornwall Insight, the official cap for July–September is released by Ofgem in the weeks leading up to the new quarter, giving households a concrete target to plan around.
The cap is calculated using a formula that blends wholesale energy costs, supplier operating costs, and other market factors. When Ofgem releases the cap, watch for the percentage change and the impact on typical dual-fuel bills. This helps you anticipate shifts in your own monthly payments and compare supplier offers accordingly.
Ofgem will on Wednesday reveal the level of the annual energy price cap for July to September as predictions suggests a 13% rise is on the way.
