The most expensive international schools in London
The top 10 of 28 schools in London by annual tuition at age 16, on 2026/2027 published fees. Tuition and entry costs are separate: a school can be cheaper per year and dearer to join.
Britain is the one market where the two overlap. Alongside the international schools — IB or American curriculum, internationally accredited, multinational intake — this ranking includes long-established British independent (private) day schools that teach the National Curriculum of England to a largely British intake. They are here because families relocating to London weigh them against the international schools, and their published fees compare directly. The curriculum column is the quick guide: on this list, “British (National Curriculum of England)” marks a UK private school.
