If you prefer well-known names for your energy, you can currently save £142 annually against the October price cap with a fixed tariff from EDF.

This week marks your last chance to take advantage of the deal, because it closes at midnight on 30 October.

The tariff is a special deal available through comparison site Uswitch, which says it’s the cheapest fix from a major supplier. 

You’ll get £25 cashback chucked your way, too, but only if you use both gas and electricity as this is paid as £12.50 per fuel. You must download the Uswitch app to take part.

If you haven’t fixed in a year or more, it’s likely you’re on a variable tariff – and fixing should save you money.

The average household can expect to pay £1,613 annually on EDF’s tariff, while the October price cap sits at £1,755. However, these figures are based on a household using the average amount of energy.

The tariff fixes the cost of each unit of electricity and not your total bill, so if you use more than the average household over the year, you’ll pay more than £1,613.

For those prepared to go with a smaller supplier, deals from Outfox Energy and Fuse Energy could save you even more money. Read more below.

Should you stick with the big six or go small?

According to the energy regulator Ofgem’s latest state of the market report published in April 2025, the big six energy suppliers make up 91 per cent of the market.

But there are 21 active suppliers, meaning that while households have a good degree of choice outside of those big names, most are sticking with who they know.

The best deals in our regularly updated list of the best energy fixes have consistently been offered by smaller suppliers – with Outfox Energy, Fuse Energy and Ecotricity regularly trumping household names.

With top deals available, it’s worth looking into whether these smaller suppliers will suit you. Make sure you check things like exit fees, the level of customer service available, how you can manage your account, and their green credentials.

For example, Fuse Energy currently has a fix available through Uswitch with an annual bill of £1,544 for the average household – a £211 saving against the October price cap and a £73 saving against EDF’s deal.

However, it’s an app-only supplier. Some customers will be comfortable with this, while others will prefer to have more options for managing their account. Exit fees are £50 per fuel.

Outfox Energy has consistently topped the table of the best energy deals, and this week is no different, with savings of £225 against the October price cap. However, it costs £75 per fuel in exit fees. The deal is available directly through Outfox Energy.

Some might be worried about the stability of smaller suppliers, but it’s worth noting that even if your energy provider goes under, your supply won’t get cut off. 

Ofgem will move you to a new supplier and try to get you the best deal – however it’s still possible your bills will go up.
