Compare energy tariffs

You’ll be switched over to your new supplier within three weeks.

Most energy companies in the UK are signed up to the Energy Switch Guarantee, which guarantees that the supplier you’re switching to will handle the process, and that it will be done within 21 days.

There’s also a two-week ‘cooling off’ period, during which you can cancel the switch free of charge.

The cheapest supplier for you depends on where you live, plus how much energy you use. So, what might be the cheapest for someone else, won’t necessarily be the cheapest for you.

That’s why it’s important to run a comparison – telling us some key details about where you live and your energy habits allows us to find the cheapest deals for you.

Once you’ve found a cheap energy deal, you can choose to sign up for alerts with Energy Monitor. We’ll keep an eye on the market and let you know when it’s time to switch - so you never have to overpay again†.

Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies must follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.

When you’re choosing a new energy deal, think about whether to go for dual fuel (where you get both your gas and electricity from the same company) or separate tariffs (where you get gas from one company, and electricity from another). It’s worth checking both options, as the combined price of separate tariffs can sometimes be less than a dual fuel offer.

Think about whether you’d like to go for a fixed deal or a variable deal. Fixed deals can be a bit more expensive at the beginning, but you’ll know that your bills won’t suddenly jump during the fixed term.

The way you pay your bills can also affect the price – you can often get a discount for paying by direct debit, and for managing your account online, with no paper communications.

No. When you’ve chosen a new deal, your new supplier will handle the switching process. They’ll contact you to let you know what date you’ll be transferred over, and they’ll contact you around the switching date to ask for a meter reading. They’ll pass this on to your old supplier so they can send you a final bill. You don’t need to contact your old supplier either - your new supplier will handle it.

Yes. When you close your account with your old supplier, they will send you a final bill. Once this payment has gone out of your account, you should cancel your Direct Debit. If your account is in credit, the supplier should send you the balance.

A dual fuel tariff just means that your gas and electricity comes from the same supplier. You can choose this option when you run an energy comparison online with MoneySuperMarket – just choose ‘Gas & Electricity (Dual Fuel)’ when you start your energy comparison.

Some gas and electricity providers will offer a discount if you switch to a dual fuel tariff – if this applies, it will be shown in the tariff details.

Be aware that the best gas and electricity deal may not be the cheapest option. It’s always recommended that you check the price of buying your gas and electricity separately, too.

Although you can choose to compare dual fuel tariffs with MoneySuperMarket, you can also choose to compare gas prices or to compare electricity prices separately, here’s how:

• Compare gas only: Simply start your energy comparison and select ‘Just Gas’. If you select just gas, you’ll only compare gas prices and you won’t see any electricity tariffs
• Compare electricity only: All you need to do is select ‘Just Electricity’ on our energy comparison page. This will show you energy suppliers that have electricity tariffs without gas or dual fuel deals included

Whilst price is important, the best gas and electricity supplier for you might not always be the cheapest.

With MoneySuperMarket’s energy comparison, you can use filters to narrow down your search. Whether you want to find a deal from a supplier that you recognise or are looking for green energy from an environmentally friendly supplier – you can filter your results to suit you.

You might also be looking for good customer service, so we include star ratings to show how happy customers have been with each supplier.

When you switch to a new energy supplier, they’ll write to you to tell you what date you’ll be switched over. They’ll also contact you around the time of the switch to ask for a meter reading, and they’ll pass this on to your old supplier, so that they can send you a final bill.

That’s all you have to do – your new supplier will handle the admin throughout the process.

You won’t need any new pipes, there won’t be any digging or drilling, and there won’t be any interruption to your gas or electricity supply.

Smart meters send details of your energy usage directly to your supplier. The smart meter display also tells you how much energy you’re using and how much it is costing you at any given point.

Smart meters ensure you get an accurate bill and the display unit could help you to work out how to reduce your consumption and cut your bills - but they won’t save you money automatically.

The best way to save money is still by switching supplier. Lots of the top deals now require you to agree to a smart meter anyway, so you can save some money today and be confident that your bills will be accurate once your switch is complete.

Cut through the jargon and get help understanding your energy bills. The key things to be aware of are:

• Your tariff: your bill will show you the name of your tariff
• Comparison rate: this highlights how much your tariff costs, so you can compare the rate
• Energy consumption: how much electricity or gas you’ve used in kilowatt hours (kWh)
• Terms and conditions: this is where you’ll find details such as any notice period, the conditions of your current price plan and everything else
