The Madrid budget tier defined
For this list "cheapest" means Madrid schools with annual fees below EUR 12,000 (USD ~13,000) at primary level, delivering credible English-medium or strongly bilingual English-Spanish education. The eight options below mix concertado bilingual schools, lower-fee private internationals, and bilingual privados.
The 8 cheapest credible options
Colegio San Patricio (Soto / La Moraleja / El Soto)
The strongest concertado bilingual school in Madrid. Multiple campuses across the affluent north-west suburbs. Bilingual English-Spanish curriculum with IB Diploma at sixth-form. Strong academic outcomes; competitive admissions. Default first choice if a concertado place is achievable for your family.
Colegio Logos
Established concertado bilingual school in Las Rozas. Strong academic culture. Spanish bachillerato pathway at sixth-form. Particularly worth considering for families committed to long-term Spanish residency.
Colegio Estudio
Long-established Madrid private school with growing English bilingual track. Strong academic and arts traditions. Mid-fee tier; modest by Madrid premium standards. Best for families wanting a Spanish-foundation school with English bilingualism, not pure international.
The English Montessori School (TEMS) Madrid
British-curriculum school with Montessori pedagogy in lower years. Modest fee point for La Moraleja. Smaller than the major British schools. Particularly suited to families who want British education with a more progressive pedagogy.
Brains International School (lower years)
British-curriculum school group with multiple Madrid campuses. Lower years sit within our budget tier; upper years move into upper-mid. Strong academic foundation. Good fit for families wanting British curriculum at lower fees than King's or Hastings.
Mirabal International School (lower years)
Mid-fee British curriculum school. Smaller scale; strong family community. Particularly worth considering for families based in west Madrid (Boadilla, Pozuelo) seeking British curriculum at modest fees.
Colegio Aleman Madrid (German International School)
German-curriculum school with IB Diploma sixth-form. German government partial subsidy keeps fees moderate. Open to non-German families willing to enter early. Strong destinations to German-speaking and Spanish universities.
Liceo Frances Madrid (lower years)
French-curriculum school within the AEFE network. French government subsidy keeps lower-year fees moderate. Open to non-French families willing to enter early. Strong French baccalaureate outcomes; portable internationally.
What you trade off
Below EUR 12,000 in Madrid, you typically trade off: international curriculum portability (concertado schools lead to Spanish bachillerato, which travels less well than IB or A-Level), facilities depth, sixth-form subject breadth, and English-language depth (concertado bilinguals have strong but not native-level English). For families willing to commit to Spanish education or accept these trade-offs, the value is excellent.
The concertado advantage
Spain's concertado system is genuinely unusual in Europe. partial state subsidy delivered through religious-foundation or community private schools, with regulated parental contributions. The best bilingual concertados (San Patricio, Logos) deliver outcomes competitive with mid-tier private internationals at a fraction of the cost. Admissions tend to favour Spanish-domiciled families and those willing to commit to multi-year placement, but international families are increasingly placed.
