Bangkok Prep is one of the most conveniently located British schools in the city, and that location is a genuine part of why families choose it. Both campuses sit in the Sukhumvit corridor: Primary (Nursery to Year 6) and Secondary (Years 7 to 13) at Sukhumvit 77 inside the T77 development, close to On Nut BTS. Founded in 2003, the school follows the National Curriculum of England through to IGCSE and A-Levels, with the Extended Project Qualification (EPQ) added at Sixth Form. Around 800 students, 60 plus nationalities, roughly 55% non-Thai and 45% Thai families. The community is notably close-knit for a school of its size, built around an active parents association called Friends of Bangkok Prep. Facilities at the secondary campus are a genuine differentiator: Olympic-sized pool, FIFA-standard football pitch, black box theatre, recording studio, and a photography darkroom. Fees sit in the mid range for Bangkok British schools. For families living anywhere along the Sukhumvit line, Bangkok Prep removes the commute problem entirely.

What You Should Actually Know About Bangkok Prep
Founded in 2003 and now in its 23rd year of operation, this British international school on Sukhumvit 77 delivers the National Curriculum of England from Pre-Nursery through Year 13, finishing with IGCSE and A Level, BTEC, and the Extended Project Qualification. Branded "Constant and True," it positions itself as a large school with a mid-sized feel, balancing roughly 1,600 students and nearly 50 nationalities across a 50% Thai, 50% international roll. Pricing sits in the mid-tier of Bangkok's British market, below the premium IB schools but above budget options.
The academic approach is thematic and inquiry-led in Primary, then subject-specialist in Secondary, with the 2025 cohort securing 329 university offers including places at Cambridge, UCL, LSE, and US Ivy-tier institutions. It suits expat and Thai families wanting British academic rigor without elite-tier fees. Days begin at 7:45am for Early Years and Primary and 8:00am for Secondary, with a published 10:1 student-teacher ratio and average class sizes around 22. Teachers hold UK Qualified Teacher Status or equivalent, and roughly a quarter hold a master's or higher. The Sukhumvit 77 site, consolidated in August 2023 when Primary moved from Sukhumvit 53, sits inside the T77 development a short walk from BTS On Nut, making the school accessible from central and eastern Bangkok via skytrain or a free school shuttle.
Sport and arts facilities are unusually deep for a single-site school: a 50-metre eight-lane Olympic pool, a FIFA-spec football pitch ringed by a 300m running track, a 400-seat auditorium, black box theatre, recording studio, and a separate 25-metre primary pool. Over 150 ECAs rotate each term, and a 1:1 device is bundled into fees from Year 3 to Year 11. Trade-offs are real. Formal EAL support runs only Year 1 to Year 9, so weaker English in Years 10 to 13 is harder to absorb. Thai-passport-only students must study Thai under Ministry of Education rules. Sibling discounts sit at 5% for second and subsequent children, modest by Bangkok standards, and Sixth Form admission is competitive given 2025 results of 92% A*-C at IGCSE and 72% A*-B at A Level. There is no IB pathway and no boarding. Best for academically able children of expat or bilingual Thai families seeking a single-campus British school with strong sport and arts infrastructure, transparent pricing, and a direct A Level route to UK, US, and Australian universities via BTS On Nut.
