Our exclusive deal with Shell Energy ends on August 28, so it's your last chance to switch to the cheapest fixed rate tariff currently available, and reduce your energy bills in time for winter. 

We've also found the cheapest Big Six fixed-rate tariff below - it's slightly more expensive than our exclusive Shell Energy offer, but for anyone specifically looking for a Big Six tariff, it's the cheapest you'll find right now.

If you're not already on a cheap fixed tariff - or haven't changed tariff for at least 12-18 months - now is a smart time to switch. Aside from saving the average home £285 per year on their energy bills compared to the energy price cap, these fixed deals will also protect you from predicted energy price hikes caused by tropical storms Laura and Marco. 

With half of all offshore oil production in the Gulf of Mexico currently paused during the storms, experts are warning we could see our energy costs rise. But if you're on a fixed rate tariff, you won't be hit by increased bills because the price of your energy is locked in.

Our Shell Energy tariff also comes with an extra £10 bill credit for duel fuel - or £5 for single fuel - when you switch. But because this is an exclusive deal, you can only get your hands on it by switching via our price comparison service

All the savings shown below are calculated based on the energy usage of the average UK home, and compared with the Ofgem price cap of £1,126. The exact amount you could save by switching depends on how much energy you use, and where in the UK you live. To find out, just pop your post code into our energy comparison service and answer a few quick questions about your energy use.
