We have a few help centre articles up with why you build up credit and debit, and how you can claim this back. Here we address whether you should.

It seems like a no-brainer, if you're owed money at the end after a few months because you haven't used as much energy as projected by your supplier, the obvious thing to do would be to claim that back and treat yourself. However, keep in mind that energy usage is calculated as an annual figure because energy use is not even across the year. 

If it's the summer months and you find you're owed potentially a big sum, consider that as you go into the winter months you might be using more energy to cover heating and it may be worth leaving that credit on there to compensate for future you. 

The alternatives to having a credit refund:

• Wait till the end of a year period with your contract
• Have your direct debit adjusted by speaking to your supplier, to be paid back over time (this will depend on your supplier)

If the money you are owed is more than the amount you pay as a monthly direct debit, you might want to claim back the difference.
