Why isn't a companion pass valid outside of Lewes District?

Companion passes are not part of the national scheme, they are a discretion that Councils fund. Existing passes will continue to be funded but no new ones are being issued. Because the Council whose area a journey commences in pays for the costs of that journey, there would need to be complex reciprocal arrangements between Councils to enable the arrangements to work. This is an issue that we will raise with the Sussex Scheme Administrators.
