The Government publishes information on the operation of the National Security and Investment Act in the NSIA Annual Report. The most recent report, covering the 2024/25 reporting period, can be found on GOV.UK. In this period, the median time from receipt of a notification to a decision to accept that notification was:

  • 7 working days for mandatory notifications;

  • 8 working days for voluntary notifications; and

  • 6 working days for retrospective validation applications.

Data on the time taken to accept notifications received between 1st April 2025 and 31st March 2026 will be published in the next Annual Report later this year.
