Blenheim Palace Heritage Foundation

Blenheim Palace Heritage Foundation scores 71 out of 100 (3 stars — Needs improvement) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 64% 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.
