Switching energy supplier if you owe money to your supplier
You might be able to switch supplier if you owe money to your current gas or electricity supplier. It depends when they sent you the bill you haven't paid.
You have the right to switch if your supplier either:
- sent you the bill less than 28 days ago
- haven't sent you a bill
If your supplier sent you a bill more than 28 days ago, you can't switch until you pay the bill.
If your energy supplier goes bust
Don’t switch tariff or supplier until your account is moved to the new supplier. You might find it harder to get any money you’re owed if you switch before this happens.
The rules are different if you haven't paid a bill because you think it's wrong. If you've complained to your supplier about the bill and they agree there might be a problem with it, they should let you switch.
If you think your bill is wrong and you haven't complained yet, you can challenge your supplier's decision not to let you switch. Check how to complain to your supplier.
If you have a prepayment meter
There are different rules for switching supplier if you pay in advance for your gas and electricity.
You can switch supplier unless you owe more than £500 for gas or £500 for electricity.
You’ll need to ask the new supplier to agree to transfer your debt along with your supply (this is called the ‘Debt Assignment Protocol’).
If your supplier doesn’t let you switch
They should tell you why they won’t let you switch. If they don’t explain or you don’t agree with what they said, you should make an official complaint to your supplier.
If you have a prepayment meter, you might want to write to your supplier and explain that you have the right to switch. You can use our template letter to switch supplier if you have a prepayment meter.
