Reference guides. What you must produce, and where it lives.Reference rather than news. Every entry answers the same two questions, carries the date it was last checked, and links to the regulator's own page for the statutory detail. These do not go out of date quietly; they get edited.

These are written as systems guidance rather than legal advice. If something here is wrong, or there is an obligation we are missing, tell us and we will correct it and say that we did. Dated deadlines live on the compliance calendar, which is kept current.

We build a version around what you sell and how you quote it, and show you it working. No paid audit, no obligation.
