Houseroom EditorialOur take
Houseroom Editorial
Our take
Independent co-ed prep school in Westminster for ages 4–13. Selective entry, C of E ethos, top-tier London fees.
Best for
- Families looking for a prep school covering ages 4–13.
- Families who prefer a co-educational setting over single-sex.
- Families who value a C of E ethos in school life.
- Children who can demonstrate strong academics at entry assessment — this is a selective school.
- Families comfortable with top-tier London independent fees in exchange for the level of provision.
Watch-outs
- Fees sit at the top of the London market. Factor in extras (uniform, trips, lunches, music tuition) before committing.
- Selective entry — assume some form of assessment at the relevant entry point. Plan tutoring or familiarisation early if needed.
- The C of E ethos shapes assemblies, holidays and pastoral life. Comfortable for committed families; worth thinking about for those of other or no faith.
