How to register for a new agent in England and Wales

This article has been updated to clarify that the new agent registration rules will apply to the new BVI agent registration scheme as it stands.
A previous version of this article said that the BVI scheme will be replaced by the new Agent Registration Scheme.
The BVI Agent Registration scheme has been launched on the day of the signing of the UK’s new EU-Turkey trade deal.
