You might find your account has a larger credit balance than normal which could be caused by a few things. You may be due to input some up to date meter readings, but this could also be due to the time of year. It's normal for your usage to fluctuate higher during winter, and lower as the summer months creep in. We review our member's payments every 6 months to help our members end their fixed term at a zero balance (or thereabouts).
The credit you build during the summer acts as a buffer when it's colder and your usage is higher, so we would advise against removing all credit from your account. If you would like to discuss having your credit paid back to you, you can call us on 0333 344 2686. Alternatively, email us at email@example.com.
Remember, whilst you're in credit your account is earning 3% interest on the first £1,000 of your credit balance, which gets credited to your account monthly.
