When does returns package arrive?

[Root]

I've been asked to return the sky items as cancelling sky. I don't want to incur any charges but I haven't yet received the returns package in the post. When should I expect this to arrive?

If you’ve successfully cancelled your subscription Sky should send out returns packaging near the end of the cancellation period, [14 days for Broadband hub and 31 days for Sky Q box(es)], to the address that the subscription was registered at.

Note:~ If you’ve switched from Sky Q to Sky Glass the packaging is usually sent out later (at 5-6 weeks) in case you change your mind about Glass.

You can use any packaging as long as it’s secure and you may want to put a note inside with your account number and a list of equipment that is included. This link explains about how to receive an email with your return labels through Royal Mail.

If you haven’t anything suitable contact Sky again and see if they’ll re-send. Keep your proof of posting safe and indefinitely and if you use Royal Mail’s collect from home service, keep a record of the tracking number.
