CharityCompare is not an England-and-Wales-only directory, and it is not a list of only large brands.
Rated profiles (a 0–100 Clarity Score and beacon breakdown) need the detailed fields in an annual return — spending splits, reserves, trustees, filing history. Those fields are most consistently published for charities with income of £100,000 and above, especially on the Charity Commission register.
Basic profiles cover every other registered charity we ingest from the Charity Commission, OSCR and CCNI: official name, number, and a link to the register. That is deliberate. Inventing a score from a thin record would be less honest than saying “not enough published data.”
If you are checking a small local charity, start at search or the directory, verify the number, and read whatever accounts exist on the register. See Scotland and Northern Ireland coverage.
