Website Maintenance Updates

We are making upgrades to which will help to improve its stability and security. These upgrades will mean the site or some of its functionality will be unavailable at scheduled times while we complete the changes. 

  • Friday 16 August from 1730 to Saturday 17 August, 1800: Our planned upgrades will affect the site more widely during this period. We will update you about the availability of services nearer the time.
  • Friday 23 August from 1600 to Sunday 25 August, 2000: Further upgrades will affect the TSO shop which supports customers to purchase publications and licences. Again, more detail about the availability of affected services will be provided nearer the time.
