What changed

Comparing the October 2026 edition with September 2026.

New agreements and new versions are easy to spot in the register. Edits to existing records are not: NHS England can change an agreement version in place, such as its purpose, its end date or the datasets it lists, without issuing a new version number, and it publishes no changelog of those edits. This site finds them by comparing each edition with the one before, and lists them under Amended.

Amended (1)

Agreement versions whose details changed in place — a revised purpose, a different end date, a change to the datasets listed, or a benefits statement that has been filled in. NHS England issues no new version number for these and publishes no changelog; they are found by comparing one edition with the last.

Changes here are counted only where the wording itself moved. An edition that reformats text — different quote characters, spacing or capitalisation — no longer counts as an amendment.
