What does Colchester Zoological Society do?

Colchester Zoological Society is a registered charity (no. 1105621) working in animals across the United Kingdom. Its latest Charity Commission filing directs 100% of spending to charitable activities, holding roughly 130 months of reserves, and files its annual accounts on time. Reported income changed sharply in 2021 (likely a merger, transfer or reporting change) — year-on-year trend labels are not meaningful across that step. CharityCompare's Clarity Score rates the organisation only from public Charity Commission accounts — accountability, financial health, efficiency and community support — not the quality or impact of its programmes.

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 Colchester Zoological Society's rating, finances, and Charity Commission status.

Is Colchester Zoological Society a good charity? +

Colchester Zoological Society scores 74 out of 100 (3 stars — Needs improvement) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 100% 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 Colchester Zoological Society a legitimate charity? +

Yes — Colchester Zoological Society is a legitimate registered charity (charity number 1105621). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1105621. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.

What is Colchester Zoological Society's charity number? +

Colchester Zoological Society's charity number is 1105621. 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 Colchester Zoological Society's charity rating? +

Colchester Zoological Society scores 74 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 Colchester Zoological Society have reviews and complaints? +

CharityCompare does not host public user reviews for Colchester Zoological Society. 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 Colchester Zoological Society? +

According to its 2024 regulator filing, 100% of Colchester Zoological Society's total spending went to charitable activities (2-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 Colchester Zoological Society's overheads? +

According to its 2024 regulator filing, fundraising costs were about 0% of total expenditure and combined overheads (fundraising plus governance) were about 6% of total expenditure at Colchester Zoological Society. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what Colchester Zoological Society'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 Colchester Zoological Society receive? +

Colchester Zoological Society reported £4.4m total income in its 2024 accounts, based on UK regulator filings. Five-year trend: restructured.

Are Colchester Zoological Society'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 Colchester Zoological Society's most recent accounts cover 2024. Scores and figures refresh whenever we re-ingest the register, so the page reflects our latest data pull rather than a one-off review.
