About this tool

This page tracks changes to Home Office and UK Visas & Immigration policy documents on gov.uk. It is a reference tool for UK immigration practitioners: a way to see when guidance changes without having to remember to check.

We monitor roughly 1,085 UKVI documents — caseworker guidance, asylum guidance, CPINs (Country Policy and Information Notes), immigration rules pages, related consultations and publications — and check each one hourly for substantive textual changes. When a change is detected, we produce a short narrative summary in plain English of what the gov.uk text now says compared to what it said before.

About the summaries

Each narrative summary is generated by an AI model (Claude, by Anthropic) from the diff between the old and new gov.uk text. The summary is a convenience for deciding whether a change is worth your attention — it can be incomplete or, occasionally, wrong. The gov.uk change note, the diff (Show diff), and the linked original document are authoritative; always verify against them before relying on a summary for casework. AI-generated summaries are flagged with a small "AI summary" chip on every entry. (A small minority of changes are purely cosmetic reformats — same content, new layout — and get a short automated note instead; those carry no chip.)

Earlier history (before live monitoring)

Each monitored document also carries a reconstructed change history going back roughly three years, where the UK Government Web Archive captured the document. Open a document from the monitored list to see it under Earlier history: gov.uk change notes plus diffs between archive captures near each change date. This is source material, not AI summarisation, so no "AI summary" chip appears. Some gov.uk changes have no archived copy and are shown as a dated note rather than a diff; those gaps are marked honestly.

What counts as a "significant" change

By default the feed shows only changes where the total number of lines added or removed exceeds a significance threshold (currently 10). Toggle "Show all changes" on the Updates page to see every detected change, including minor edits and typo fixes.

What this tool does not do

• It does not interpret changes or say whether they are favourable or unfavourable.
• It does not advise on what action a lawyer should take.
• It is not exhaustive — only UKVI policy documents are monitored; case law, statutes, secondary legislation and statements of changes are tracked elsewhere.
• It is not a replacement for reading the gov.uk source: every entry links to the original document.
