Our take

Independent co-ed all-through school in Middlesex for ages 3–18. Non-selective intake, top-tier London fees.

Best for
Who thrives here
  • Families wanting one school across the whole journey (ages 3–18) rather than separate prep + senior.
  • Families who prefer a co-educational setting over single-sex.
  • Families who would rather not put their child through a selective entrance assessment.
  • Families comfortable with top-tier London independent fees in exchange for the level of provision.
  • Internationally-mobile families wanting IB or American-style qualifications rather than only A-levels.
Watch-outs
Know before applying
  • Fees sit at the top of the London market. Factor in extras (uniform, trips, lunches, music tuition) before committing.
  • SEND provision isn't documented in our profile. If your child has an EHCP or specific learning needs, ask admissions about case-by-case capacity before applying.
  • Curriculum is IB/American-style rather than A-Level. Check that your university plans (UK or otherwise) align before committing to the route.
