London is one of the most expensive cities in the world for international schooling, and the published headline tuition is only part of the story. Capital fees, lunch, school transport, residential trips, exam entry fees and the inevitable enrichment activities can quietly add ten to twenty per cent on top of the printed price. This 2026 cost guide breaks down what families relocating to London should actually expect to pay across primary, senior school and the sixth form.
Tuition: what the headline price actually buys
Most international schools in London quote tuition by year group. Realistic 2026 day-school ranges per academic year are:
Early Years (Nursery and Reception, ages 3-5): around £18,000 to £30,000. Lower Primary (Years 1-3): around £22,000 to £30,000. Upper Primary (Years 4-6): around £24,000 to £33,000. Years 7-11: around £30,000 to £40,000. Sixth form (Years 12-13): around £33,000 to £45,000, with the most prestigious day schools approaching £55,000.
If you are looking at boarding (full or weekly), expect a further £15,000 to £25,000 per year. Some schools offer flexi-boarding for one or two nights a week as a halfway option.
Capital and registration fees
Almost every London international school charges a non-refundable application fee (typically £200 to £400) and a non-refundable acceptance or registration fee (£500 to £2,500) when a place is offered. Many also charge a one-time capital contribution of £2,000 to £8,000 at the point of enrolment, plus a refundable security deposit equivalent to one term's tuition. These figures are usually discounted for siblings, but rarely waived in full.
Hidden costs that move the budget
Lunch is rarely included in tuition. Mandatory hot lunches in London international schools cost £1,200 to £2,200 per child per year. School bus or coach service runs £2,000 to £4,000 per year depending on distance. Uniform and sports kit can add £500 to £1,200 in the first year, especially in schools with formal blazers, separate PE and games kits, and house colours.
External exam fees for IGCSE, A Level, IB Diploma or AP papers are usually billed separately at £80 to £150 per subject, which adds up quickly across a typical entry of nine to eleven IGCSEs and three to four A Levels or six IB subjects. Residential trips, weekend excursions and DofE expeditions add another £500 to £1,500 per year. Music tuition, individual sports coaching and external tutoring (common in Year 6 and Year 11 in London) are paid extra by the family.
Top international schools in London with verified profiles
Three London schools popular with relocating families have published profiles on International School Advisor: TASIS England (American curriculum and IB Diploma west of London), Halcyon London International School (IB MYP and DP in central Marylebone), and International School of London (IB with mother-tongue programmes in Chiswick).
Tax, scholarships and discounts
Private school fees in the UK are no longer VAT-exempt: from January 2025, 20% VAT applies to tuition. Most schools have absorbed part of the increase but families have seen total fees rise by 12-18% in the past two years. Scholarships at top London schools (academic, music, sport, art) typically reduce fees by 5-25%, and means-tested bursaries can further reduce fees for families that qualify. Sibling discounts of 5-15% on the second and subsequent children are common.
Some employers in finance, law and tech offer education allowances as part of expat packages. If you are negotiating a relocation, push for a clear annual education allowance per child rather than a one-off contribution.
Practical tips for budgeting
When you compare offers from different schools, normalise on a "total annual cost" line that includes tuition, capital amortisation, lunch, bus, exam fees and trips. The true gap between two schools quoted at "£32,000" and "£38,000" can shrink to a couple of thousand pounds once everything is included. Build in a 5-7% annual fee increase when planning a multi-year stay in London.
