final metre reading to my old supplier

when can i expect you to send my metre reading to my old supplier so they can close my account and refund me excess payments

I believe it is sent quickly, however it goes to a 3rd party for verification (legal requirement) and that can take up to 6 weeks, it happens with all utility companies and you are at the mercy of the 3rd party.

@shonawilson11 yep Scudo is right. I can confirm that your readings have now been sent out, so its just of them passing through validation before they reach your previous supplier.
