Kidney Research UK

Kidney Research UK scores 78 out of 100 (4 stars — Good) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 79% of its spending goes to charitable activities (3-yr avg) 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.

The register data used for this profile lists Kidney Research UK as a registered charity (charity number 252892). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/charity-details/?regId=252892&subId=0. Check the current entry and the identity of anyone requesting money.

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).

CharityCompare does not host public user reviews for Kidney Research UK.

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, 79% of Kidney Research UK'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 20% of total expenditure and fundraising plus separately reported governance figures amount to about 21% of expenditure (2023–2025, disclosed years); these categories can overlap, so this is not a distinct total of all administration costs at Kidney Research UK.
