Finding the right international school in London can feel daunting, because the capital's education landscape is dominated by British independent and state schools, while genuinely international schools offering the IB or an American curriculum are far fewer. For globally mobile families who want continuity across countries, those international options matter. This 2026 guide explains the curricula available, highlights leading international schools in and around London listed on International School Advisor, sets out fees, and offers a practical way to choose.
Why choose an international school in London
Families relocating to London often prefer an international school when they expect to move again, want their child to follow the International Baccalaureate, or are continuing an American or global programme started elsewhere. These schools bring together students from dozens of nationalities, provide strong transition support for new arrivals, and offer qualifications recognised by universities worldwide.
Curricula available in and around London
London's international schools primarily offer the International Baccalaureate continuum, from the Primary Years through to the Diploma, and the American curriculum with Advanced Placement. This contrasts with the many British schools offering GCSEs and A Levels. Choosing an international programme keeps a child aligned with a global pathway, which is valuable for families who anticipate further relocations.

The schools below are active partner schools listed on ISA, each with a verified profile, reviews and fee information.
Halcyon London International School
Located in central London, Halcyon London International School is a non-selective IB World School offering the Middle Years and Diploma programmes. Its central location, small class sizes and fully international ethos make it a popular choice for globally mobile families based in the city.
TASIS England
Just outside London in Egham, Surrey, TASIS England is a long-established American international school offering the American curriculum, Advanced Placement and the IB Diploma on a large campus. Its blend of American and international pathways attracts families seeking breadth within easy reach of west London and Heathrow.
International school fees in London
Fees at international schools in and around London are among the highest in Europe. Annual tuition generally ranges from around £24,000 in the primary years to roughly £38,000 in the senior school and IB Diploma years. On top of tuition, budget for a registration or assessment fee, a refundable deposit, and recurring costs such as lunches, transport, uniforms, trips and examination entry. Some families also factor in the cost of living near their chosen school, which can be significant in central London.
How to choose the right school
Start with the curriculum your family needs, whether that is the IB for global mobility or an American pathway. Consider location carefully: a central London school suits families living in the city, while a campus school in the surrounding counties offers more space and facilities but a longer commute. Prioritise a visit to assess pastoral care, the international mix of the student body, and the support offered to new arrivals. Finally, check availability early, as places in popular year groups are limited.
