Hey there, @mrgamblinman,
Thanks for coming to the Community.
As you already mentioned, the country setting will only update on the next billing date (when your plan renews). 🙂
Alternatively, you can cancel your subscription and wait for it to end. Once it has ended, you'll be able to update your country setting at https://spotify.com/account through a drop-down menu.
Hope this clears things up!
