Summer School 2026 costs £1,350 per week (28 June – 15 August, minimum 2 weeks, ages 8–17). The fee includes 15 hours of English + 5 hours of leadership training per week, the Trinity GESE exam and Young Leader Award, full-board boarding-house accommodation, two full-day and two half-day excursions weekly with all entrance fees, the full activity programme, weekly laundry and a BOSS welcome pack. Not included: airport transfers, BOSS Academies (tennis, horse riding, football), early/late arrivals (£150), unaccompanied minor service (£125 return), extra nights (£250) and specific room requests (£150).
Students live in secure boarding houses with staff living on campus and 24-hour supervision. Most rooms have 2 beds, with some singles and larger rooms for younger children; roommates are matched by age with mixed nationalities so English is spoken. Excursion supervision is 1 adult per 12 students for ages 8–12 (always accompanied) and 1 per 15 for ages 13–17. The BOSS Spring Experience (29 March – 18 April, £1,195/week) also runs at the same campus.
