The procedure is captured under the Central Product Classification (CPC) code 50220000 and has a procurement value projected at £475,000. The tender is taking place in the United Kingdom, particularly across Edinburgh, Glasgow, or Inverness, with submissions required electronically via ScotRail's Wax Digital e-sourcing portal. The tender period concludes on 20th March 2026, with a subsequent stage expecting candidate invitations by 20th April 2026.
