Latest updates

We regularly consult with the sector to gain insights that help us to review and update the documents within our Standards and Guidelines Catalogue. Information on current consultations can be viewed in our public consultation hub, and further information on recently reviewed, updated or archived documents is shared with staff and suppliers in our regular Standards and Guidelines Technical Advice Note newsletter.

Publication consultation hub

Technical Advice Notes were previously published every time an individual operational policy document was ratified and updated in our standards catalogue. However, in 2024 we have updated the format into a regular newsletter that not only lists recently updated documents, but also notifies future consultations and highlights upcoming plans in our forward work programme.

An archive of our previous Technical Advice Notes is below.
