Switching energy suppliers by mistake or without permission is known as Erroneous Transfers. Thankfully, these can be rare and easily fixed. It is very unlikely that your energy supplier can be switched without your permission. However, if you are a tenant in your home and do not pay the bills yourself, your landlord can technically change the energy supplier without your permission.
There are a number of factors that may be the reason your supplier has switched you mistakenly. These include:
Computer error
Your meter is not labelled properly in the national database
There has been a human error
Mixing up details after moving into a new property
A usual sign of an erroneous transfer is a letter or email stating that you are leaving. Once this has occurred please contact our customer services team immediately on 0345 222 3030 or drop us a message through our live chat.
