There are three basic steps to switching energy supplier:
- compare your tariff with other deals on offer (see “Compare prices” section below)
- choose the best deal
- tell the new supplier you want to switch and they’ll organise the change for you.
It’s a fairly simple process but it can seem daunting. You need to make sure you have the right information before you begin.
Understand your bill
Before you start, it's helpful to get a clear picture of what you need and what's on offer.
You should check how much energy you use. Your energy supplier must give you personalised information about your bill which explains what tariff you’re on, your energy use and details of any exit fees.
The best way to compare prices and deals is by using online price comparison websites. You should check two or three. Some price comparison websites have been accredited by Ofgem. You could also use the comparison tool on Citizens Advice or call one of the energy switching companies, such as uSwitch, for advice.
Be wary of salespeople who offer deals on your doorstep or over the phone. Don’t be pressured into signing anything and take your time to consider any offers. It’s completely fine to say no to an offer.
If you find the deals on offer confusing, you can get help from your local Citizens Advice.
How to switch energy supplier
You can switch online or over the phone. You just tell the new supplier you want to switch and they'll contact your current supplier to organise the change. It shouldn’t take longer than 21 days.
- your postcode
- the name of your current supplier
- the name of your current energy tariff and how much you spend
- an up-to-date meter reading
- your bank details if you’re paying by direct debit.
You may also need your Meter Point Access Number (MPAN) and your Meter Point Reference Number (MPRN). You’ll find most of this information on your bill.
Make sure you take a meter reading the day before you switch. You should receive a final bill from your current supplier within six weeks. If they owe you any money, you should get a refund soon after that.
There is a 14-day cooling off period in case you change your mind. If you cancel during this period, you’ll stay with your current supplier.
Some suppliers have signed up to a voluntary list of commitments called the Energy Switch Guarantee which should make switching easier. Check to see if your supplier has signed up.
