Please ensure an actual meter reading has been submitted, rather than an estimated meter read, if this is what we have used on your recent invoice. We do not automatically refund credit balances if we are still supplying you, as we will use this credit to offset future consumption charges we bill you. If you would prefer the balance to be refunded, as long as we have billed you up to date with actual readings, and any other accounts you have with us are paid in full, then please email and request your refund. This will be paid in the same way your original payment was made.
