King's College School Wimbledon

King's College School Wimbledon is one of London's top academic day schools, founded in 1829 and on Wimbledon Common since 1897. Boys 7 to 18 with a co-educational sixth form, around 1,500 pupils across junior and senior.

Sixth formers split roughly 60 percent A Level and 40 percent IB. In 2025, 47.7 percent of A Level grades were A*, the IB cohort averaged 41.25 points, and the school was named Sunday Times IB School of the Year. Senior fees from September 2025 sit around GBP 11,400 a term, with means-tested bursaries up to 100 percent at 11+, 13+ and 16+.

The campus blends Victorian red-brick around the Common with a new music school and sports complex. Families describe a fast, busy environment that suits academically curious children, with a Kindness at King's culture working to soften the pressure. The parent body skews affluent and professional. Best fit for academically strong children in south west London who can handle pace, and sixth form girls wanting a top IB or A Level cohort.

• KCS Wimbledon is treated by London-based Reddit, HENRYUK and Mumsnet posters as a top-tier London independent, often named alongside St Paul's, Westminster and Latymer for academics.
• IB results sit at the very top of London (42-point average cited in r/IBO), and A-level results are widely described as second only to St Paul's among London independents.
• The Wimbledon and KCS-junior pipeline is heavily discussed on HENRYUK and r/london; Rowans is named as the main feeder prep.
• A 2024 Mumsnet thread captured a wave of disappointment from prospective parents: cramped classrooms, dated D&T facilities, claustrophobic sixth form, with one parent flagging culture-of-sexism concerns.
• Pupils on the boys' tour are described in The Good Schools Guide as charming and grounded rather than arrogant, but the school is not pitched as the right environment for every child.
