King's College, The British School of Madrid

King's College, The British School of Madrid is the Soto de Viñuelas campus of the King's College group, founded in 1969 and now part of the Inspired global schools network. It is a full through-school taking children from 16 weeks in Early Years to age 18 in Sixth Form, with roughly 1,580 pupils drawn from a highly international community. Teaching follows the English and Wales National Curriculum, leading to IGCSE at 16 and then a choice between A-Levels and the IB Diploma Programme in the final two years - a dual-pathway Sixth Form that is unusual among Madrid's British schools.

The school's standout credential is its 2024 British Schools Overseas (BSO) inspection by Penta International, which awarded it an 'Outstanding' grade in all categories - the highest band available under the UK government's overseas inspection framework. That places its inspection and accreditation profile at the top tier. Academic outcomes are strong and consistent with that standing: in 2025 the IB Diploma cohort averaged 35.5 points (top score 45), 45% of A-Level grades were A*-A, and 63% of IGCSE grades were A*-A.

Uniquely for the city, the Soto de Viñuelas campus offers boarding for ages 11-18 and markets its boarding house as among the best in Europe, opening the school to families outside Madrid and overseas. Instruction is in English, with Spanish taught throughout and a student body spanning around 50 nationalities, so the environment is genuinely cosmopolitan rather than expatriate-only.

Fees for 2025/26 run from roughly EUR 8,115 at the youngest end to EUR 20,700 at the senior end before boarding costs, positioning it in the upper bracket of Madrid international schooling. The combination of an Outstanding BSO judgement, a dual A-Level/IB Sixth Form, and on-site boarding makes it a strong fit for internationally mobile families who want a British-rooted education with a recognised quality stamp.
