How we score charities +
The Clarity Score is a 100-point rating from UK regulator filings (Charity Commission for England and Wales, OSCR and CCNI). 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.
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. Display stars use the same bands as the labels: 90–100 → 5★ Exceptional; 75–89 → 4★ Good; 60–74 → 3★ Needs improvement; 1–59 → 2★ Poor; 0 → not rated.

Frequently asked questions
Common questions about Operation Smile United Kingdom's rating, finances, and Charity Commission status.
Is Operation Smile United Kingdom a good charity? +
Operation Smile United Kingdom scores 69 out of 100 (3 stars — Needs improvement) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 54% of its spending goes to charitable activities and its accounts are up to date. That reflects how transparent and financially healthy it looks on paper — it does not measure the real-world impact of its work, so treat it as one factor alongside the cause you care about. 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. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.
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.
What is Operation Smile United Kingdom's charity rating? +
Operation Smile United Kingdom scores 69 out of 100 on CharityCompare (3 stars — Needs improvement). 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.
Does Operation Smile United Kingdom have reviews and complaints? +
CharityCompare does not host public user reviews for Operation Smile United Kingdom. Instead you get a filing-based Clarity Score, cause spend, reserves and red flags such as late accounts (1 filing concern(s) noted on this profile). For formal complaints about a charity, contact the Charity Commission, OSCR, CCNI or the Fundraising Regulator as appropriate.
How much of my donation reaches Operation Smile United Kingdom? +
According to its 2025 regulator filing, 54% of Operation Smile United Kingdom's total spending went to charitable activities (3-yr avg across disclosed years). That is the closest official figure to "how much of your donation reaches the cause" — it is an average across all spending in the filing, not a pound-by-pound breakdown of an individual gift.
What are Operation Smile United Kingdom's overheads? +
According to its 2025 regulator filing, fundraising costs were about 46% of total expenditure and combined overheads (fundraising plus governance) were about 47% of total expenditure at Operation Smile United Kingdom. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what Operation Smile United Kingdom's chief executive is paid — where disclosure rules apply, senior pay appears in the trustees' annual report on the Charity Commission register.
How much income does Operation Smile United Kingdom receive? +
Operation Smile United Kingdom reported £7.5m total income in its 2025 accounts, based on UK regulator filings. Five-year trend: stable.
Are Operation Smile United Kingdom's accounts up to date? +

Where is Operation Smile United Kingdom based? +

An open statutory inquiry scores 0. The score measures reporting on paper, not programme impact. CharityCompare is free for donors, takes no commission on donations, and scores cannot be bought.
How often is this page updated? +
This profile was last updated on 17 July 2026 from the latest UK regulator data available to CharityCompare, and Operation Smile United Kingdom's most recent accounts cover 2025. Scores and figures refresh whenever we re-ingest the register, so the page reflects our latest data pull rather than a one-off review.
