No payout floor or distribution transparency for endowed foundations

US private foundations must distribute roughly 5% of assets annually and file machine-readable returns; the UK has no minimum payout and no requirement to report payout ratios. ACF's Foundations in Focus 2025 shows record giving (£8.24bn) and some foundations spending 'above sustainable levels', but sector-wide payout behaviour is unknowable from unstructured accounts. ACF itself argues a mandatory floor could act as a ceiling: a live, unresolved, evidence-poor debate.

Tens of billions sit in charitable endowments with no visibility into whether they are deployed or accumulated. Even a 0.5-point rise in average payout across the largest 300 foundations would release hundreds of millions annually for chronically unfunded fields.

A Charity Commission annual-return requirement for large grantmakers to report payout ratio; a sector-led voluntary 4-5% distribution commitment (ACF-convened); and an HMT/DCMS review of accumulation rules to settle the floor-vs-ceiling question with actual data.

// Build together: Counterparty: ACF convening large grantmakers into a voluntary 4-5% payout commitment; the statutory floor is the state-led end-state.

Tens of billions sit in endowments with no payout visibility, but the reform is contested, evidence-poor and politically resisted, with no dated trigger, so it stays a slow opportunistic fight.
