Question to the Home Office:

To ask the Secretary of State for the Home Department, if she will take steps to identify the number of non-UK national workers that were brought to work on the construction and maintenance of offshore wind farms within UK territorial waters under the Offshore Wind Workers Immigration Rules Concession 2017 before it expired on 30 April 2023.

All those who came to the UK under the concession were stamped at the Border rather than through visa routes and therefore no data was collected.
