Four pillars — Accountability & Transparency (40), Financial Health (30), Financial Efficiency (20), and Community Support (10) — each scored on a continuous scale, not pass/fail cutoffs. A statutory inquiry sets the score to 0 automatically. [Full methodology →](https://www.charitycompare.org.uk/methodology) Accountability & Transparency Scored from filings 40 points — filing history (15), trustee oversight (15, scaling up to a board of three or more), declared policies (10). Financial Health Scored from filings 30 points — reserves (15, full marks 3–24 months, tapering on both sides), income stability (10), liabilities to assets (5, scaling down as debt rises). Financial Efficiency Scored from filings 20 points — program expense ratio and fundraising cost, each on a graduated scale (not a single cutoff). Kept at 20% of the total: financial-ratio scoring alone is not a reliable effectiveness signal (see "why not just an overhead ratio?" below). Community Support Scored from filings 10 points — volunteer-to-staff ratio from Charity Commission workforce data, scaling continuously up to a 2:1 ratio. Overall score Sum of all pillar points.

CharityCompare never tells you where to donate. Is Operation Smile United Kingdom a legitimate charity? + Yes — Operation Smile United Kingdom is a legitimate registered charity (charity number 1091316). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1091316.

What is Operation Smile United Kingdom's charity number? + Operation Smile United Kingdom's charity number is 1091316. Check that number on the official register (Charity Commission, OSCR or CCNI) or this CharityCompare profile before you donate — scammers sometimes reuse real numbers on fake appeals.

The Clarity Score V1 sums four pillars from UK regulator filings: Accountability & Transparency (40 pts), Financial Health (30), Financial Efficiency (20), and Community Support (10). Stars use the same bands as those labels — 90+ is 5★ Exceptional. It is not an impact ranking.

Are Operation Smile United Kingdom's accounts up to date? + Filing status: up to date (last filing 2026-06-24). CharityCompare flags late or missing accounts separately from the financial score.
