The UK centre has already moved: the Playbook sets the principles, the transparency standard reaches the departments and their arm's-length bodies, the Department for Transport has published its own AI action plan for the sector, and the auditors measure what follows and publish what they find. The direction of travel is set from the centre, without a statute.
What the instruments ask of an individual office is local: an inventory that is true, a written policy, named checkpoints, training records and a review cycle. Under a written position, AI already does defined work across the office, each task with a named human check before it is relied on.
