ICS London International School

ICS London is a small central-London IB World School with a primary campus on Wyndham Place in Marylebone and a secondary on Star Street in Paddington. One of only two London schools running the full PYP, MYP and Diploma pathway.

Around 150 students from over 60 nationalities, kept deliberately small for an individualised, mixed-ability classroom. The IB Diploma average sits around 32 points, comfortably above the global mean. Fees in 2025/26 run from roughly GBP 22,890 in nursery to GBP 34,200 in the Diploma years.

Families praise the small classes, the boutique feel, and a learning support team that takes children with mild SEN seriously. The international mix is genuine and the central postcode suits expat families who want a school close to their flat. The flip side of being small is a thinner activity programme than the bigger London IB schools and higher transient turnover. Best fit for internationally mobile families wanting full IB continuity in zone 1, who value a personal, non-pressured environment over the breadth of a 1,000-pupil school.
