Finding the Right International School in London
London is one of the world's great expat cities, and for families relocating here, finding the right international school in London is often the most pressing priority. With dozens of schools offering IB, American, and British curricula, the choice can feel overwhelming — but the quality of education available is genuinely exceptional. This guide covers everything expat families need to know for 2026: which schools to consider, what fees to expect, and how to navigate admissions.
International Curricula Available in London
London's international school landscape is notably diverse. Families can choose from the International Baccalaureate (IB), the American High School Diploma, the British National Curriculum (GCSE and A-Level), the French Baccalaureate, and various bilingual programmes. The IB is particularly well represented, with multiple authorised World Schools across the city. Many schools also offer both the Middle Years Programme (MYP) and Diploma Programme (DP), providing continuity from age 11 through to university entrance.
Top International Schools in London
Below are some of the most respected international schools in London for expat families in 2026. Each has been selected for its academic standing, international community, and breadth of curriculum.
TASIS England
TASIS England — The American School in England — is a co-educational, college-preparatory school set on a stunning 46-acre campus in Thorpe, Surrey, just 18 miles from central London. Founded in 1976, it offers the American curriculum alongside the IB Diploma Programme for students aged 4–18. TASIS is known for its outstanding university placement record, with graduates accepted at leading institutions in the US, UK, and Europe. The boarding and day programme attracts a genuinely international student body from over 50 nationalities.
Halcyon London International School
Halcyon London is a boutique IB World School in the heart of Marylebone, offering the IB continuum from Primary Years through the Diploma Programme. With small class sizes and a student body of around 200 pupils from 50+ countries, Halcyon offers a truly individualised education in one of London's most central locations. Its progressive approach emphasises student agency, wellbeing, and global citizenship — ideal for families seeking a smaller, more personalised international school experience.
International School of London (ISL)
ISL has been serving London's international community since 1972. Located in Chiswick, west London, it offers the full IB continuum — PYP, MYP, and DP — for students aged 3–18. With around 500 students from over 60 nationalities, ISL maintains a strong focus on mother-tongue language education, with an award-winning Mother Tongue programme supporting over 30 languages. Its location in west London makes it particularly accessible for families living in Richmond, Kew, and Hammersmith.
International School Fees in London
London is one of the more expensive cities globally for international schooling. Annual tuition fees for international schools in London typically range from £18,000 to £35,000 per year, with boarding fees at residential schools such as TASIS adding an additional £15,000–£20,000 on top. Some boutique city-centre schools charge a premium for their central location and small class sizes. Families should also factor in registration fees (£250–£1,000), annual capital levies, and the cost of uniforms and school trips. Many schools offer means-tested bursaries, and some employers who relocate staff to London include school fees as part of the expat package.
Practical Tips for Families Moving to London
London is large and varied, so the neighbourhood you choose will strongly influence which school makes most sense. Families settling in west London (Richmond, Kew, Chiswick, Fulham) will find ISL and TASIS conveniently located, while central London families often favour Halcyon. North London has several strong options including the International School of London Queens Campus in Woking and Nord Anglia schools. Always check transport links before choosing a school — London traffic can be brutal, and a school with a good bus network or walkable location makes a big difference to daily life.
Most international schools in London admit throughout the year, but popular year groups fill quickly, particularly Year 1, Year 7, and Year 12. Applying 12–18 months in advance is advisable, especially for well-established schools. Entry requirements typically include school records, language assessments, and in some cases entrance examinations for older students. If your child's English is still developing, ask specifically about English as an Additional Language (EAL) support — most top schools have strong EAL programmes.
