Under normal circumstances, anyone can switch their energy supplier and usually it is quick and easy to do so. However, you may not be able to switch if you’re in debt with your current energy provider.Your existing supplier will stop you from switching if you have an outstanding debt owed to them. In addition, a new provider may not want to take you on as a customer if you have had difficulty paying a previous bill.You are considered to be in utility debt when the amount outstanding has remained unpaid for a period exceeding 28 days or you owe more than £500. However, if you owe less than £500 and you are on a prepayment meter, is it possible to change energy company.If you are in debt with your current supplier because they have failed to do something, you will be able to switch if you can prove this. If you are also in debt with other bills, such as credit cards, mobile phones or car insurance, you may wish to seek advice from a debt charity.
