Sign up for the Trader Support Service.
The Trader Support Service assists businesses moving goods between Great Britain and Northern Ireland under the Windsor Framework. A new version of this service will go live for all users on 20 October 2026, at which point all new movements must be submitted through the updated platform. Existing users will be migrated automatically, but those not yet registered should sign up via the official website to ensure they are prepared for these requirements.
