What it costs in pounds, and why that moves.
The school bills in baht. A British family paying from sterling income pays a different amount every term because GBP/THB moves. The same All programmes (Ladprao 88 campus, single fee schedule) fee of 341,000 THB is:
| GBP/THB | Annual fee in pounds |
|---|---|
| 48 | £7,104 |
| 44.9 (today) | £7,594 |
| 42 | £8,119 |
Between a strong-pound year and a weak one the sterling cost of this school moves by about £1,015 a year per child. A family paying termly from a UK account at a high-street bank's 3 to 5 per cent spread adds £304 a year on top. Fee payments are the single largest transfer most expat families make, which is why the transfer method matters more here than anywhere else in the budget.
A termly 113,667 THB transfer at the mid-market rate costs a fraction of a bank's spread. Compare the GBP to THB quote before the first invoice.

Reading the fee schedule
- The hidden fees catalogue: the £30,000 to £70,000 your school will charge that is not in the tuition schedule.
- The fee inflation trap: how £18,000 in Year 1 becomes £32,000 by Year 13.
- The British family's decision framework for international schools in Asia.
- Where the £25,000 actually goes: the international school operating budget nobody publishes.
How The Baht records school fees
Every figure comes from the school's own website or fee document, recorded with its URL and the date it was checked. Figures are annual tuition as the school states them, in Thai baht, for the academic year shown. Where a school prints termly fees only, the annual figure is the termly fee multiplied by the number of terms and is marked as such. Refundable deposits are listed but excluded from first-year totals. Pound figures use the mid-market GBP/THB rate on the day the page was built (Latest daily mid-market snapshot · 10 November 2026) and are rounded to the nearest pound. Fee schedules change every year, usually between March and July; the checked date on this page is the date the figures were last read from the school's site. Corrections: editorial@thebaht.com.
