London Institute for Mathematical Sciences

London Institute for Mathematical Sciences scores 47 out of 100 (2 stars — Poor) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 100% of its spending goes to charitable activities (3-yr avg) and its accounts are late. 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 London Institute for Mathematical Sciences as a registered charity (charity number 1139814). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/charity-details/?regId=1139814&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.

London Institute for Mathematical Sciences's charity number is 1139814. 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.

London Institute for Mathematical Sciences scores 47 out of 100 on CharityCompare (2 stars — Poor). 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.

Instead you get a filing-based Clarity Score, cause spend, reserves and red flags such as late accounts (3 red flags on this profile: late accounts filing; poor filing history; sharp income decline). 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, 100% of London Institute for Mathematical Sciences'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.

Across the recent disclosed accounts used for this score, fundraising costs were about 0% of total expenditure and fundraising plus separately reported governance figures amount to about 3% of expenditure (2022–2024, disclosed years); these categories can overlap, so this is not a distinct total of all administration costs at London Institute for Mathematical Sciences.
