What is the benefit of a fixed price deal?

In general, the cheapest energy deals are typically online tariffs, which are paid monthly by Direct Debit, but this isn’t suitable for everyone, so it’s best to run a cheap energy comparison to find the best deal for you.

You only need your postcode to compare quotes and find the cheapest energy tariffs in your area – we can estimate your annual usage based on the size of your house – but to get the most precise quotes, it’s best to have your latest energy bill to hand so you can enter accurate energy consumption details.

And don’t be surprised if you have to change energy supplier to get the best deal, and to a company that isn’t one of the Bix Six – gas and electricity companies regularly change their available deals, and the best prices can often be found with smaller suppliers.

Who’s the cheapest energy supplier right now?

Fixed rate gas and electricity tariffs are usually among the cheapest energy deals on the market, and almost always cheaper than standard variable rate plans, which act as each supplier’s default tariff that you’ll automatically be placed on once your fixed-rate deal ends.

That’s why it’s so important to shop around and switch before your current deal ends – if you roll over to a standard variable deal, you’ll end up paying more for your energy.

Fixed rate energy deals usually last for between 12 and 18 months (though longer deals may be available), and ensure that you pay the same rates for your gas and electricity for the duration of the deal.

It’s worth noting that only the unit price is fixed, so the amount you pay each month will still go up and down, depending upon how much energy you’re using. And because these deals are fixed for an agreed term, you may have to pay an exit fee if you want to leave your arrangement early – if you want to switch to a new deal before your current one ends, first work out whether you’ll actually save money once the exit fees have been factored in, if not, it may be worth sitting on your existing deal until it expires.
