Meeter reading and British Gas refund

Hi I just wanted to know how long it will take to notify British Gas of my final meeter reading because I have quite a lot of credit with them that I am hoping would be refunded as soon as possible.

@cem5545 We sent both your readings to your old supplier on your supply start date, but it’s normal for the reads to take around 6 weeks to reach the old supplier, as they go through various third parties from both sides to be validated.

The gas and electricity industries operate separately, so it’s possible they can arrive at a different time and therefore the final bills will be received separately too.
