Published quarter, now past
The Ofgem price cap limits the unit rates and standing charges that suppliers can charge on default variable tariffs, and it is reviewed every quarter, in January, April, July, and October. Crucially, the cap does not limit your total bill, it only limits the rates: if you use more energy than Ofgem's typical consumption figures, your bill will be higher even if your supplier follows the cap to the letter. For October–December 2026 the national Direct Debit standing charges are 54.83p per day for electricity and 29.68p per day for gas.

Dual Fuel Deals: Frequently Asked Questions
Is dual fuel always cheaper than separate suppliers?
Not always but it can be. Many suppliers offer a small dual fuel discount to customers who bundle both fuels. However, the cheapest overall deal at your address may still be two separate single-fuel tariffs. Switch compares both options side by side so you always see the true cheapest outcome.
