Always open the live fee PDF rather than recycling a neighbour’s old quote: Living in Brussels and Living in Antwerp.

Ask what is excluded: enrolment, capital fees, bus, lunch, uniforms, IB exams, and after-school clubs.

European Schools in the Brussels area offer Category I and II places for eligible EU-institution and related staff at heavily subsidised rates, while Category III places publish annual fees in the low thousands rather than private IB bands. Eligibility and language sections decide access more than willingness to pay. Belgian public and communal schools are far cheaper but language-first in Dutch, French, or German depending on the Region: Enrol in public school and English in Belgium.

Choose housing for the school gate, not the other way around: Waterloo and south-east Brussels communes for many English IB campuses, Antwerp for AIS, Leuven research households for a different Dutch-speaking map: Best places for families, Brussels cost of living, and Leuven cost of living. Crèche costs still sit beside tuition for younger siblings: Childcare costs. Country context: How expensive is Belgium and Where to live.
