Cornwall Insight has today released its final forecast for the October–December 2025 Default Tariff Cap (price cap). The new forecast predicts the cap will rise to £1,737 a year for a typical dual fuel household this winter. This would represent an increase of £17 and 1% from the current price cap which is set at £1,720 per year.
Richard Neudegg, director of regulation at Uswitch.com comments: “A predicted 1% increase in the October price cap may not seem significant - but it brings into sharp focus that consumers need to get ready for the winter now.
“Most households will use significantly more energy in the colder months, so the October cap rates will dictate the cost of keeping our homes warm as winter starts to bite for those households still on the price cap.
“Bill payers on a standard variable tariff can beat these expected rises and save on bills by switching to a well-priced fixed deal now.
“We are seeing the strongest savings in three months, around £298[1] for the average household.”
