In July 2020, we consulted publicly on proposed changes to the current General Directions for Navigation in the Port of London 2016 and in response to feedback, a number of further amendments have been made.
Following the completion of this process, the General Directions for Navigation in the Port of London are now published and will become effective as of Monday 1 March 2021. On that date the General Directions for Navigation in the Port of London 2016 will be revoked and should not be used.
