Latest accounts (2025) · £7.2m spent
Charities usually allocate governance costs across their other spending categories, and these reported figures add up to more than total spending, so governance is not drawn as a separate slice. The accounts table shows it separately.

Evidence and interpretation
In 2025, reported income was £7,495,196 and expenditure was £7,229,194. Income exceeded expenditure by £266,002. This annual balance is not the charity’s available cash or unrestricted reserves.
Income rose 4.8% compared with 2024. Read the accounts notes for restricted grants, legacies and one-off receipts before treating the movement as a trend.

Look beyond the score
We have not added a source-checked programme outcome for this charity. That is a gap in this profile, not evidence that the charity has no impact. Its annual report may contain results that have not been assessed here.
Reported grants to institutions: £0 (2025-06-30). This is spending reported in the annual return, not a measure of beneficiary outcomes or an open grant opportunity. It may already be included in charitable expenditure. Check the source accounts.
Counts of services delivered describe activity. They do not by themselves establish lasting change, what would have happened without the programme, or cost-effectiveness. Results with different definitions, populations or years should not be ranked against each other.

Start a comparison with Operation Smile United Kingdom →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.

Common questions about Operation Smile United Kingdom's rating, finances, and Charity Commission status.
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 (3-yr avg) 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.
The register data used for this profile lists Operation Smile United Kingdom as a registered charity (charity number 1091316). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/charity-details/?regId=1091316&subId=0. Check the current entry and the identity of anyone requesting money. Registration does not verify a particular appeal; Clarity Score summarises filing transparency, not programme impact.
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.
Operation Smile United Kingdom scores 69 out of 100 on CharityCompare (3 stars — Needs improvement). The Clarity Score (method v1.1) 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.
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 (one red flag on this profile: high fundraising costs). For formal complaints about a charity, contact the Charity Commission, OSCR, CCNI or the Fundraising Regulator as appropriate.
Across the recent disclosed accounts used for this score, 54% of Operation Smile United Kingdom's total spending went to charitable activities (3-yr avg across disclosed years).

Across the recent disclosed accounts used for this score, fundraising costs were about 46% of total expenditure and fundraising plus separately reported governance figures amount to about 47% of expenditure (2023–2025, disclosed years); these categories can overlap, so this is not a distinct total of all administration costs at Operation Smile United Kingdom.
