Shouldnt he have moved it to his new address? we are getting letters from the inland revenue now.

Yes, he should. How long has this been going on? Have you asked him directly to change address? What happens with the post currently? If you are forwarding it, tell him nicely that you are unable to continue doing this and will be returning it to sender.
