Coverage differs slightly by nation, because the registers themselves do:
- England and Wales — registration is compulsory above £5,000 income, and detailed annual returns support full Clarity Score rating.
- Scotland (OSCR) — every Scottish charity must register regardless of income.
- Northern Ireland (CCNI) — a newer register, so some charities have a shorter published filing history.
Where a charity’s published data is too thin to score fairly, we show a basic profile with its official register details rather than inventing a rating. Charities that appear on more than one register are shown once, on the profile with the richest data.
