No GiveWell-equivalent evaluator for UK domestic causes

London hosts world-class effective-giving infrastructure, Founders Pledge, Longview Philanthropy, Giving What We Can and an Open Philanthropy presence, and it channels UK tech wealth almost entirely to global health and catastrophic-risk causes. No organisation publishes rigorous, public cost-effectiveness rankings for UK domestic charities and civic interventions. NPC offers bespoke consultancy, small efforts like SoGive lack scale, and donors seeking evidence-ranked domestic options have nowhere authoritative to look.

CAF shows wealthy Britons cite lack of confidence in impact as a barrier to giving. A trusted domestic evaluator would raise giving volumes and steer them towards the systematically unfunded categories this map documents, at a cost trivial relative to the funds influenced.

An independent UK-domestic evaluator at £2-3m a year publishing open cost-effectiveness assessments of UK charities and civic interventions, paired with a pooled UK effective giving fund: a natural first grant for Founders Pledge members or the Office for the Impact Economy to catalyse.

// Build now: First artefact: open cost-effectiveness rankings of UK domestic charities from public accounts and evaluations, plus a pooled effective-giving fund.

A trusted domestic evaluator would raise giving and steer it to unfunded fields cheaply, and no dated trigger creates urgency, so it can be built opportunistically.
