International Schools in London

Ages 11-18 · IB · Kingston upon Thames, South West London · ~240 students

Marymount is a compelling choice for families who want outstanding IB results in a small, single-sex boarding-capable environment - and who are comfortable with a Kingston location 12 miles from central London. If you need a school in zones 1-2, or a co-educational setting, look elsewhere.

Ages 4-18 · American · St John's Wood · ~1,350 students

If you're relocating from the US and want continuity with the American system - or you're planning a return to the States - ASL is the obvious choice. The facilities are exceptional for central London. Expect a serious waitlist and fees at the top of the London market.

Ages 2-18 · IB · Kensington, Hampstead & Westminster · ~600 students

Southbank is the right call if you want a genuinely central IB school, don't need a single unified campus, and want your child in a small-class environment where they know their teachers well. If consistent facilities across all years matter, look at ISL instead.

Ages 11-18 · IB · Marylebone, Central London · ~190 students

Halcyon suits families who want a boutique, parent-founded IB school in central London, don't need a primary option, and are comfortable with a small cohort and no on-site sports. If you're after a large campus with traditional sports provision, look elsewhere.

Ages 2-18 · IB, American · Cobham, Surrey · ~1,400 students

ACS Cobham is a genuinely strong choice for American-curriculum families or families who want the flexibility of both American diploma and IB Diploma - provided you are realistic about the Cobham commute and the transient nature of the community. If you want a stable long-term community or are not tied to an American-style education, explore other options in this guide.

Ages 3-18 · IB · Chiswick, West London · ~500 students

ISL is a strong option for families who want the IB in a genuinely inclusive, non-selective setting - and who value mother-tongue language support above almost everything else. The Chiswick location suits families in Richmond, Kew, and Hammersmith well; it's a harder sell from north or east London.

Ages 3-18 · American, IB · Thorpe, Surrey · ~650 students

TASIS is the right choice for American-curriculum families who want boarding in a genuinely beautiful campus setting and are prepared for the Thorpe location. For day families travelling from central London, the journey of 45-plus minutes each way is the trade-off that makes or breaks the decision.

Ages 2-18 · IB · Barnet, North London · ~400 students

Dwight works best for families who want a warm, non-selective school where teachers genuinely know your child, and who are comfortable with a Barnet location and a multi-campus setup. If you need central London proximity or a single unified site, look at Southbank or Halcyon instead.

Ages 3-18 · French, IB, British · Bloomsbury, Central London · ~700 students

Jeannine Manuel is the right school if you want genuine French-English bilingualism in London - not a French school with an English add-on, but a true bilingual programme with serious academic standing. If you are not committed to French as a language of instruction, the school's distinct ethos may feel like a constraint rather than a strength.

Ages 4-18 · IB, American · Hillingdon, West London · ~600 students

ACS Hillingdon is worth a serious look if you want strong IB results, campus space, and flexibility in exit qualifications - and you're realistic about being in Hillingdon. The bus network covers a lot of London, but this is a suburban school and the daily journey from zone 1 or 2 is an honest 40-50 minutes each way.

Ages 3-18 · IB · Marylebone, Central London · ~150 students

ICS London suits families who want the IB in a genuinely small, central London setting - and who are comfortable with two campus sites and a school of around 150 students. If cohort size or sporting facilities matter, Southbank or Halcyon are stronger options at a similar price.

Ages 3-18 · French · South Kensington, Central London · ~3,450 students

The Lycee is the only option in London for families committed to the French national curriculum at full scale - and at these fees, it is extraordinarily good value. If your child will sit the Baccalaureate or you are relocating between French-speaking countries, this is an easy decision. If you are not tied to the French curriculum, explore the bilingual and IB alternatives in this guide before committing.
