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.

Is The Zoological Society of London a good charity? + The Zoological Society of London scores 85 out of 100 (4 stars — Good) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 78% 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 The Zoological Society of London a legitimate charity? + Yes — The Zoological Society of London is a legitimate registered charity (charity number 208728). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/208728.

What is The Zoological Society of London's charity number? + The Zoological Society of London's charity number is 208728. 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.

How much of my donation reaches The Zoological Society of London? + According to its 2025 regulator filing, 78% of The Zoological Society of London's total spending went to charitable activities (3-yr avg across disclosed years).

What are The Zoological Society of London's overheads? + According to its 2025 regulator filing, fundraising costs were about 2% of total expenditure and combined overheads (fundraising plus governance) were about 2% of total expenditure at The Zoological Society of London.

Five-year trend: growing. Are The Zoological Society of London's accounts up to date? + Filing status: up to date (last filing 2026-06-24).

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 The Zoological Society of London'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.
