With only two forms to fill in (or a quick chat on the phone if you prefer), you can give your current energy supplier the heave-ho and switch to a cheaper one in the time it takes to make a cup of tea.

But before you put the kettle on, here’s the information you’re going to need:

-Your postal address, together with an email address.
-The name of your current gas and electricity supplier(s).
-The name of your current tariff(s).
-Whether or not you’re on an Economy 7 deal for electricity.
-How you currently pay for your energy – cash/cheque or direct debit.
-Your bank account details (for if and when you decide to switch).

And either:

-Your annual gas and electricity usage, measured in kWh

OR

-What you spend each month on gas and electricity, separately.

What to do

First we need to know some things about your current gas and electricity supply.

-Go here: and click the green ‘Lower your bills’ button.
-Fill in your postcode and click ‘Find address’. Choose your address from the list.
-Choose whether you want to compare gas, electricity or both.
-Tell us whether you currently use the same supplier for your gas and electricity or not.
-Tell us who currently supplies your gas and electricity by clicking the relevant logo(s).
-Tell us how you currently pay for your energy by selecting one of the options from the drop-down list.
-Tell us if you have an Economy 7 deal on your electricity. If you’re unsure, check your latest bill, or speak to your supplier.
-Choose the tariff you’re on from the drop-down list. Again, this will be on your bill if you’re unsure.

Next, we need to know some things about how much energy you use.

-If you know how much energy you use, click the ‘I know my usage’ button and fill in the boxes below for your gas and electricity consumption.
-If you don’t know how much you use, click the ‘Help me estimate’ button and choose Low, Medium or High use for both gas and electricity. You’ll see that the box below the words Low, Medium and High changes, explaining what each means.

Finally:

-Tell us how you’d like to pay your new supplier using the drop down list. 
-Type your email into the last box – this way you can get a copy of your results via email, in case you want to come back and switch later.

That’s the first form done – you’re halfway there.

Choose your saving

The next screen will load a table showing a list of energy suppliers, telling you how much you’ll save by switching to each of them.

This is all based on the information you just entered, so the supplier at the top of the table is the one which will save you the most money.

If you’re happy with it, click the green ‘Apply now’ button. If you’d prefer to speak to someone, click ‘Call to apply’ and you’ll get the phone number to call. Be aware, however, that not all energy firms will take applications over the phone (more on this later*).

You’ll then see an application form for setting up your account with the new supplier. All you need to do is fill in a few personal details, including your bank account information, before clicking the green ‘Proceed to switch’ button at the end.

And that’s your part of the switching process done!

What happens next?

The new supplier will receive the application form within 24 hours of you clicking that last green button. They’ll check and process the application and if it’s successful, they’ll arrange the switch with your current supplier.

Within the next two weeks you’ll get a welcome pack from the new supplier, outlining its terms and conditions.

If there’s anything you don’t like, or if you’ve changed your mind, you’re free to cancel the switch within the cooling-off period. This is usually 12 to 14 days after your new supplier has confirmed the details of the new contract through the post. You can use this time to check through the details and reassure yourself that it’s the right move for you.

When the cooling-off period ends, your new supplier will call your old one to tell them they’re taking over your supply.

The only thing you’ll have to do is submit your meter readings after four weeks, so that your old account can be settled and your new account can be opened. You’ll get a letter about this.

But that’s it – there’s no interruption to your gas or electricity supply, no new pipes, no drilling or digging – just a couple of forms and perhaps a phone call.

The whole transition to a new supplier, from application to completed switch, takes between four and six weeks.

Other useful information

If you don’t want to fill out the forms on our website yourself, call 0800 177 7861 and one of our experts can take you through the process.

We’re on hand to help between 9am and 8pm Monday to Thursday, from 9am to 5.30pm on Friday and from 10am to 2pm on Saturdays.

This is a good option for those who aren’t online. Of course, the chances are they won’t be reading this! But an increasing number of people are thinking about the possibility of a parent or other elderly relative switching supplier – they could give us a call.

Or there’s nothing to stop someone using another person’s computer to make the switch online, so long as there’s an email that can be used and the computer owner is fully involved and knows what’s going on.

If you’re just having trouble with filling in the online forms, you can use our ‘live chat’ feature to speak to one of our experts using your keyboard. Just type in your questions and our experts will reply - like sending text messages.
