How to switch online in five steps

1. Head to a comparison site

There’s plenty to choose from, and is one of them! Our team of energy experts has put together a whole load of guides and tips for saving money and saving energy.

2. Enter your postcode

Because gas and electricity prices vary by region, so to do the tariffs and suppliers available. Wherever you see our handy postcode tool, simply enter yours and instantly compare the energy tariffs available in your area.

3. Enter your usage information

It’s helpful to have a recent bill to hand, but if you don’t you can just answer a few questions about the size of your home and your lifestyle. This should give a good estimate about which tariff suits you.

4. Pick a new tariff

Don’t be afraid to think things over for a few days if you need to. Do a thorough check of the tariff you’re leaning towards by reading reviews, refining what you think you’ll need from your tariff, and whether you can find any other deals that might suit you. Once that’s all done, you’re ready to go!

5. Confirm and pay

Just enter your bank details and full address and that is it! The new supplier will take care of the rest. Remember, from this point you’ve still got a 14 day cool off period in case you have a change of heart.

I’ve switched supplier, what next?

Do I have to contact my current supplier?

Nope. New suppliers take care of everything, and this includes cancellation of your old tariff. Similarly, new suppliers will organise the switch date. This means you won’t be charged twice for the service. Make sure you cancel your Direct Debit after your final payment to your old supplier, just to be on the safe side.

How long will switching take?

Most switches are done within 17 days, but it can take up to 3 weeks. Your new supplier will let you know your exact switch date. Also check if the supplier you want to switch to is signed up to the Energy Switch Guarantee. The Guarantee means suppliers have to stick to certain rules such as allowing a 14 day cooling off period if you change your mind or aren’t happy with your service.

Will I be billed twice?

New suppliers will only start charging from your switch date. So no, you shouldn’t be charged twice. Do cancel your Direct Debit though, just to make sure!

When do I begin paying my new supplier?

The old supplier will send you a final bill for the period up to the switch date. On that date, the new supplier takes over.

Will I be charged an exit fee for leaving my current supplier?

If you switch within the 6 to 7 weeks before the end of your current plan, the exit fee will be waived. This is a rule put in place by Ofgem, and all suppliers have to follow it.

Should I cancel Direct Debits?

After the final payment, cancel your direct debit just to be on the safe side.

    Do you get monthly statements as I only have a computer and don’t have a mobile.

      Hello Paul,

      Thank you for your comment.

      Usually, Energy Providers give out monthly statements, may it be paper statements (mailing it to your address) or paperless statement (electronic mail). This should be confirmed by your provider.

    Do all energy suppliers ask for payment for first month in advance?

      Hi Jacky,

      Not all energy suppliers ask you to pay in advance. Usually, small energy suppliers who are more vulnerable to cash flow changes are the ones who often ask for advance payment. Energy companies can keep their costs down by buying their gas and electricity in advance and then pass on the savings they get to the consumers by offering them value plans.

      Hope this helps.

    Currently in rented property with electricity only provided through SSE THTC. I understand that sse have had the monopoly on thtc for some time. Are there any energy companies out there that I can switch to for a more competitive tariff than I currently pay?
