London and Bangkok are rarely shortlisted together by accident: families weighing this pair usually have a UK passport and a regional Asian role, or vice versa. London offers the world's deepest schools market and an unmatched university feeder; Bangkok offers strong IB outcomes, abundant household help and a cost of living about a third of London's. Both cities deliver English-medium choice from age 3 to 18.
Schools landscape side by side
London has the world's deepest private school market, including more than 30 dedicated international schools and hundreds of traditional British day and boarding schools. Shortlists include ACS Cobham and Hillingdon, The American School in London, ICS London and Southbank International, alongside Westminster, King's College School Wimbledon and the Surrey day schools. There are no debentures in the British private sector.
Bangkok runs more than 200 international schools, the largest market in Southeast Asia. The flagship names are Bangkok Patana, NIST International School, ISB, Harrow Bangkok, Shrewsbury International, KIS International and Brighton College Bangkok. NIST leads the IB league with a 37-point average in 2025; Patana posts a 35-point average at scale.

Fees and value for money
London private day schools run GBP 22,000 to 35,000 a year for senior years, with international schools clustering at the higher end. The 20 percent VAT applied to private school fees from January 2025 has been passed through in full at most schools.
Bangkok flagship schools sit at THB 800,000 to 1,200,000 per year for senior school, roughly USD 22,000 to 33,000, with capital fees of THB 250,000 to 700,000 at first enrolment. Bangkok cost of living is around 64 percent lower than London, and equivalent international school fees are 30 to 45 percent lower. Use the cost calculator for the all-in five-year number.
Curriculum availability
London tilts heavily British (National Curriculum, IGCSE and A Level) with strong IB and American provision. Bangkok tilts British and IB, with American available through ISB. The IB Diploma is the safest portable credential if your assignment is uncertain. See the British curriculum hub and IB hub for the detail.
Neighbourhoods families pick
London families pick Kensington, Hampstead, St John's Wood and Chiswick for the central international schools, and Wimbledon, Richmond, Cobham and Sevenoaks for the day-school commuter belts. A four-bedroom family home in those catchments runs GBP 4,500 to GBP 8,500 per month.
Bangkok families pick Sukhumvit (Phrom Phong, Thong Lor, Ekkamai) for Bangkok Patana and NIST shuttle routes, Sathorn for central schools and Brighton College Bangkok, and the closed Nichada Thani compound for ISB. A three-bedroom condo on central Sukhumvit runs THB 80,000 to 180,000 per month, often with full hotel-grade facilities.
Lifestyle and climate
London delivers world-class culture, parks, sport and the deepest university feeder network in Europe, balanced against grey weather and long commutes. Bangkok delivers a tropical, low-cost daily rhythm, abundant household help, and easy weekend travel across Asia. Air quality in Bangkok varies seasonally and is a real-life factor for some families. Both cities are broadly safe for families.
Verdict: who picks which city
Choose London for school choice, university pipeline, and a child already inside the British system. Choose Bangkok for stronger family economics, larger homes, and a softer family rhythm at a third of the daily cost. Many UK families take a Bangkok posting for the savings then return for sixth form. Run both cities through the school finder quiz to size the right move.
One pattern we see often: a UK family takes a Bangkok role for Years 7 to 11 to build savings and let the children sit IGCSE inside an established British curriculum school. They then return to a London day school or UK boarding for sixth form, with the IGCSE marks doing the heavy lifting in the entrance round. That sequencing turns a perceived disruption into a tax-efficient saving and a stronger university application, which is worth modelling carefully against straight London tenure.
