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.

Full 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. 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 The Zoological Society of London's rating, finances, and Charity Commission status.

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. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.

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.

What is The Zoological Society of London's charity rating? +

The Zoological Society of London scores 85 out of 100 on CharityCompare (4 stars — Good). 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 The Zoological Society of London have reviews and complaints? +

CharityCompare does not host public user reviews for The Zoological Society of London. Instead you get a filing-based Clarity Score, cause spend, reserves and red flags such as late accounts. For formal complaints about a charity, contact the Charity Commission, OSCR, CCNI or the Fundraising Regulator as appropriate.

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). 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 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. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what The Zoological Society of London'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 The Zoological Society of London receive? +

The Zoological Society of London reported £93m total income in its 2025 accounts, based on UK regulator filings. Five-year trend: growing.

Are The Zoological Society of London's accounts up to date? +

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.
