How do I transfer credit into my bank please

@Mwp5510 we can refund any excess credit on an account as long as we keep one month’s payment in the account & have up-to-date meter readings. If we can have some meter readings, we’ll know how much we can refund back to you.

We don’t tend to suggest refunding credit in summer as the idea is that you build up credit so that you don’t have to increase your payments in winter, though.
