Understanding how international school admissions in London work is essential for any family relocating to the UK capital. London has one of the world's richest collections of international schools, offering the International Baccalaureate, American, French and other national curricula alongside the traditional British independent sector. Places at the most sought-after schools are competitive, and the process has its own rhythm of registration, assessment and offers, so knowing what to do and when makes all the difference. This 2026 guide walks expat families through admissions step by step, with realistic fees in pounds and practical tips to secure a place.
Applying from overseas adds paperwork and timing to juggle alongside visas and housing. Families who begin early and stay organised consistently end up with better options and far less stress in their first months in London.
How the admissions process works in London
For international schools in London, the journey usually follows these stages. First you research and shortlist schools, ideally visiting in person or attending an open day. Then you register your interest and submit an application, paying a registration fee. Next comes assessment, which may be an age-appropriate test, an interview or a taster day, and at some schools a reference from the current school. Finally, on acceptance, you confirm the place by paying a deposit and the first term's fees. The most established schools work to set registration deadlines well in advance, while many international schools also accommodate families relocating mid-year, subject to availability.
Admissions timeline: when to apply
For a September 2026 start, a sensible timeline is to research schools and register interest nine to twelve months ahead, complete applications and assessments six to nine months before, and confirm your place and arrange uniforms and transport three to six months out. The most in-demand schools and the entry points into examination years fill earliest, and some traditional independent schools require registration even further in advance, so check each school's specific deadlines as soon as you can. If you are moving at short notice, focus on the international schools that operate rolling admissions and ask directly about current availability in your child's year group.
Required documents
Have these ready to keep the process moving:
- Child's passport and visa or immigration status documents.
- Parents' passports and proof of a London address, or evidence of your relocation.
- Birth certificate.
- School reports and transcripts for the last two years.
- A reference from the current school, if requested.
- Any educational psychologist reports if your child has additional learning needs.

International school fees in London (2026)
London is one of the more expensive cities for international schooling. As a 2026 guide, annual tuition runs roughly:
- Primary: GBP 20,000–28,000.
- Secondary: GBP 25,000–33,000.
- Sixth form / IB Diploma: GBP 30,000–38,000+.
On top of tuition, budget for a registration fee, a deposit (often a term's fees, partly refundable), lunches, uniforms, trips and any optional transport. Always request the full itemised fee schedule so you can compare schools on total annual cost rather than the headline figure alone.
Why expat families choose international schools in London
London has excellent state schools, but places are allocated by catchment area and faith criteria and can be hard to secure at short notice, and the curriculum is the English National Curriculum taught in English. Families who want continuity with a home-country system, a globally portable qualification such as the IB, or instruction that eases the transition from another country therefore often choose an international school. These schools are also experienced at welcoming children mid-year and supporting those who arrive with English as an additional language, which removes a great deal of friction during a stressful relocation. For many globally mobile families, that combination of portability and support is worth the premium.
Language support and settling in
Teaching at London international schools is in English, and most run dedicated English as an Additional Language support, so a child who is not yet a confident English speaker is not at a disadvantage when applying. When you visit, ask specifically about the support programme for new arrivals, typical class sizes, and how the school helps children settle socially in their first term. A strong induction and a buddy system help a child find their feet quickly, which matters enormously during a demanding family move. At home, keep routines steady and encourage friendships outside school hours to build both confidence and language.
Admissions tips and choosing the right area
London is vast, and where you live shapes both your school options and your daily commute. Many international families settle in areas such as Hampstead, Chelsea, Kensington, Richmond and the leafier suburbs near the larger campuses, balancing community, housing and travel time. Public transport is excellent, but a long cross-city journey is wearing for a young child, so shortlist schools and neighbourhoods together. Apply to two or three schools rather than betting on one, keep digital copies of every document ready to upload, and treat the admissions experience as information in itself: a school that responds promptly and answers your questions fully tends to be the same school that supports your family well once term begins.
