What Westminster Under School does

Westminster Under School is a co-educational (from September 2026) independent day school located on Vincent Square in central London, serving pupils aged 4 to 13. Originally established in 1943 as the preparatory branch of Westminster School, it traces its institutional lineage to a school re-founded by Elizabeth I in 1560. The school provides a broad academic curriculum covering core subjects alongside an extensive co-curricular programme in sport, music, drama, art, chess, and an expeditions programme that leverages London's museums, galleries, theatres, and churches. The school's primary customer segment is London families seeking selective independent prep education, with the majority of graduating pupils (64 of approximately 65 in 2025) progressing to Westminster School's Fifth Form at age 13+. A second GTM motion targets gifted state school pupils through the Westminster Platform widening access programme, comprising Platform Pups (Year 2, 12 pupils), Platform (Year 5, 45 pupils), and Platform+ (Year 10, 42 pupils), delivered via partnerships with 37 London state schools.

The school operates as a registered charity (No. 312728) within the Westminster School charity structure, governed by a Governing Body. Revenue is generated primarily through termly tuition fees (subscription model) with supplementary income from charitable donations managed by a Development Office. The school commits over £2 million annually to means-tested bursaries, with a stated ambition to increase this to at least £2.5 million. Technology usage is limited to standard educational tools — Microsoft Office, Zoom, Atom Learning, Sora, and Mathsaurus — with no proprietary platform. The January 2025 ISI inspection found the school fully compliant with a 'significant strength' identified in its enrichment programme.

The institution is in the midst of a structural co-education transition: girls will join Reception, Year 3, and Year 7 in September 2026, supported by a new Chapter House building. Westminster School's Fifth Form becomes co-educational in 2028, with full co-education through Year 13 by 2030, materially expanding the addressable family market.
