Lisbon has emerged as one of Europe's most affordable English-medium school markets, with the British, American and IB systems all well represented at half the Brussels price. Brussels has the deeper Tier 1 bench thanks to ISB, BSB and the European Schools network, but families pay a premium for that depth.
Schools landscape side by side
Lisbon's anchor names are Carlucci American International School of Lisbon (CAISL), St Julian's School, The British School of Lisbon (BSL), TASIS Portugal, United Lisbon International School and Park International School. CAISL and St Julian's run the longest waitlists, particularly at Year 7 and Year 12 entry. TASIS Portugal, opened on a new Sintra campus, has expanded capacity significantly. United Lisbon is a newer build with strong IB credentials and good availability outside Year 11.
Brussels has more than a dozen credible international schools. The big four shortlists are International School of Brussels (ISB), British School of Brussels (BSB), St John's International School and Brussels American School. The European Schools network, four campuses, serves EU institution staff at heavily subsidised fees and has parallel intake for private families. Waitlists at ISB and BSB can run 12 to 18 months for popular entry points, so families relocating with an EU institution job, NATO posting or corporate transfer apply as soon as the assignment is confirmed.

Fees and value for money
Lisbon is genuinely affordable for an EU capital. British and American premium schools sit at EUR 13,000 to 23,000 for primary and EUR 16,000 to 26,500 for secondary. Portuguese bilingual private schools, often a better long-term cultural choice, run EUR 9,000 to 16,000. Capital fees and uniforms add EUR 1,500 to 3,500 in year one. See our Lisbon fees guide for the complete picture including the IB Diploma uplift.
Brussels is one of Europe's most expensive cities for premium international schooling. ISB publishes annual fees of EUR 22,590 to EUR 49,714 across age groups, BSB EUR 34,400 to EUR 44,015. The European Schools are dramatically cheaper for EU institution families (effectively free for Category I), EUR 13,452 for Category II and EUR 3,566 to EUR 16,389 for Category III. Plan a 4 to 6 percent annual fee uplift. The cost calculator includes Brussels capital fees and bus charges by default.
Curriculum availability
Lisbon covers IB Diploma, British IGCSE and A Level, American Advanced Placement and Portuguese bilingual streams. The IB Diploma is the most portable choice and is increasingly the default at United Lisbon and TASIS Portugal. Cambridge IGCSE plus A Level runs at BSL and St Julian's. Families on shorter postings tend to pick IB; longer-stay families often choose Portuguese bilingual for cultural integration.
Brussels has one of the broadest curriculum mixes in Europe. ISB runs the full IB continuum and is the largest IB World School in Belgium. BSB runs IGCSE plus A Level with an IB Diploma option. The European Schools follow the European Baccalaureate, recognised by EU and most international universities. Visit the IB hub for Diploma-specific guidance.
Neighbourhoods families pick
Lisbon families cluster in Cascais and Estoril for proximity to St Julian's and CAISL, the Carcavelos coastline for beach lifestyle and good bus routes, Sintra for TASIS and a wooded family environment, and Lisbon central (Parque das Nacoes, Lapa, Restelo) for United Lisbon and BSL. A three bedroom apartment in central Lisbon runs EUR 2,200 to 4,000 per month; a four bedroom villa in Cascais runs EUR 3,500 to 6,500.
Brussels families cluster in Tervuren, Sterrebeek and Wezembeek-Oppem for BSB catchment, Watermael-Boitsfort, Uccle and Ixelles for ISB families, and Etterbeek and Schaerbeek for EU institution families using the European Schools. A four bedroom family home in Tervuren or Sterrebeek runs EUR 2,800 to 4,800 per month; central Brussels flats are EUR 1,800 to 3,500.
Lifestyle and climate
Lisbon has a Mediterranean climate with mild winters and dry, warm summers around 27 to 32 degrees Celsius. The city is famously safe, walkable in patches, and built around a coastal lifestyle that defines family weekends. Brussels has a temperate Atlantic climate with cool, wet winters and short, mild summers; family life leans indoors through autumn and winter. Brussels has the deeper cultural and museum offering for older children and unmatched train access to Paris, London, Amsterdam and the Ruhr. Lisbon has the better outdoor lifestyle, surf-school culture for children, and easier weekend travel to the Algarve and Madrid.
Verdict: who picks which city
Choose Lisbon if value, sunshine and a relaxed family rhythm matter more than school depth at the absolute top tier. It suits remote workers on the D7 or D8 visa, families with younger children, and anyone who wants Western Europe at half the Brussels cost.
Choose Brussels if EU institution access, NATO or corporate connectivity matters, you want the deepest IB and British school bench in continental Europe, and your role can carry the premium. It is materially stronger for families with secondary-age children where ISB, BSB or the European Schools will shape university applications.
The cost calculator shows the five year all-in delta on tuition plus housing usually lands at EUR 80,000 to 160,000 per child in Lisbon's favour at the premium tier, and even wider if Brussels families pick ISB or BSB without employer support.
