Erroneous transfer: what to do if you’ve been switched by mistake

Have you been switched to a new energy supplier without your permission? That’s an “erroneous transfer”. Find out more about why this happens and what to do.

Have you been sent a “Sorry you’re leaving” email by your energy supplier – but you didn’t think you were leaving?

If you’ve been switched to a new energy supplier by mistake, this is what’s known as an erroneous transfer.

Think this has happened to you? Don’t worry! It’s easy to fix, and you might even be able to get some compensation. Keep reading to find out more about why erroneous transfers happen, and what to do about them.

What's an erroneous transfer?

An erroneous transfer is when you’re switched to a new energy supplier by mistake. 

The good news is that problems switching energy supplier are fairly uncommon. According to Which?, just 5% of people find switching supplier difficult. Erroneous transfers are thankfully pretty rare.

Can my energy supplier change without my permission?

No. If you’re the energy account holder, then your energy supplier can’t be changed without your permission. 

There is one exception to this: if you’re a tenant and you don’t pay the bills yourself.

  • If you’re a tenant and you pay your own energy bills, then only you can switch suppliers. Your landlord can’t do it for you. (Though they might suggest a ‘preferred supplier’ in your contract.)

  • If you’re a tenant and your landlord pays your energy bills, then they get to choose which energy supplier you’re with. So technically they can switch suppliers without your permission.

In general, if your name is on the bills, then you have to give your permission to switch.

Why erroneous transfers happen

There are a number of reasons why an energy supplier might accidentally switch you:

  • They’ve mixed up your details with someone else’s – this can happen if you live in a flat or new build property

  • There’s been a human error: for example, someone accidentally selected the wrong address from a drop-down menu

  • There’s been a computer systems error

  • In very rare cases, a property is signed up to commit fraud

  • Your meter isn’t labelled properly in the national database

What happens during an erroneous transfer?

The first sign of an erroneous transfer might be an unexpected letter or email that says something along the lines of “Sorry you’re leaving”, from your current energy supplier. You might also receive a final bill when you didn’t ask for one.

How long does an erroneous transfer take to sort out? 

Once you’ve let us know that you think you’re being switched by mistake, we’ll take care of the rest. We aim to sort out erroneous transfers within 12 weeks. 

We’ll get in touch with the other energy supplier to stop the switch. We’ll do this by raising an objection to the switch. It’s important to do this as quickly as possible after the switch started, so please let us know as soon as you realise what’s happening. 

Who do I pay for energy while an erroneous transfer is being fixed?

If you’re an OVO member who is switched by mistake, you won’t have to pay a penny to the new supplier. We will continue to send your bills as normal. Simply keep paying your usual Direct Debits to us. 

I’m trying to switch to OVO, but something’s gone wrong

If you’re trying to switch to OVO, but you’ve noticed that some details (like your MPAN number) are wrong on your welcome letter or first bill, then it might be that we’ve taken over the wrong supply.

In this case, please let us know as soon as possible. We’ll get it sorted in no more than 12 weeks. 

Not sure if you’ve had an erroneous transfer? Check the supply numbers on your recent bills. These are also known as your MPAN or MPRN numbers. They identify your gas or electricity supply.

If your usual supply numbers don’t match the numbers on your “welcome” letter, or your first bill from your new supplier, then something may have gone wrong with your switch. 

Here’s a bit more information about MPAN and MPRN numbers and how to find them

Can I get compensation for an erroneous transfer?

Yes! If you’ve been switched by mistake, on or after 1 May 2019, you may get compensation.

You’ll get a minimum of £30 for the inconvenience. The maximum is £120, which is payable if your energy isn’t switched back to your original supplier in a timely way2. The new supplier (the one you’re switched to) is the one that pays up.

This rule was introduced by the energy regulator, Ofgem.

What normally happens when you change energy supplier?

Switching energy suppliers is usually a piece of cake!

All you have to do is:

  • Search the internet to get quotes from different suppliers and find one that’s best for you

  • Tell that supplier you’d like to switch to them

  • Give them your details (including postcode and bank details)

  • Leave the rest to them, and you’ll be all switched over within 21 days!

Your gas and electricity won’t be interrupted while you’re switched to a new supplier. And you should get your final bill from your old supplier within 6 weeks3
