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 Wiener Library Endowment Trust's rating, finances, and Charity Commission status.

Is The Wiener Library Endowment Trust a good charity? +

The Wiener Library Endowment Trust scores 67 out of 100 (3 stars — Needs improvement) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 86% 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 Wiener Library Endowment Trust a legitimate charity? +

Yes — The Wiener Library Endowment Trust is a legitimate registered charity (charity number 290660). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/290660. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.

What is The Wiener Library Endowment Trust's charity number? +

The Wiener Library Endowment Trust's charity number is 290660. 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 Wiener Library Endowment Trust's charity rating? +

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 Wiener Library Endowment Trust have reviews and complaints? +

How much of my donation reaches The Wiener Library Endowment Trust? +

According to its 2024 regulator filing, 86% of The Wiener Library Endowment Trust's total spending went to charitable activities.

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.
