London is the world's most multilingual capital, and a bilingual international school in London can give children genuine fluency in two or more languages alongside an internationally recognised academic qualification. The capital hosts French, Spanish, German, Italian, Mandarin and Japanese pathways at primary and secondary level, often layered with the IB Diploma or A-Levels. This 2026 guide outlines the main bilingual options for expat families, fees to plan for, and the admissions essentials in central London and the home counties.

FAQs
Are bilingual schools in London more expensive than mainstream independents?
Not necessarily. State-funded foreign-system schools (Lycée, Deutsche Schule, Vicente Cañada Blanch) are significantly cheaper than equivalent independent schools. Premium bilingual primaries are priced in line with top London preps.
Can my child enter a London bilingual school without prior language exposure?
Yes, in early years (ages 3 to 6) most bilingual primaries accept children with no prior exposure to the second language. From Year 3 onwards, schools generally expect a baseline of fluency.
Will a bilingual education affect university applications?
Universities in the UK, US and Europe view bilingual qualifications favourably. The IB bilingual Diploma in particular is well regarded for university admissions worldwide.
