The Best Preparatory Schools in South West London
Published: 17 June 2026
The best preparatory schools in South West London sit within a capital that has the highest concentration of independent education in the UK. Participation rates vary by borough, in Kensington and Chelsea, 45.3 per cent of pupils attend independent schools, compared with a London average of around 10.1 per cent.
Preparatory schools play a key role in academic progression at 11+ and 13+, with many structured explicitly around Common Entrance, pre-testing and scholarship preparation. South West London’s leading schools commonly feed into highly selective senior institutions including Westminster School, St Paul’s School, King’s College School Wimbledon, Dulwich College, Harrow School and Eton College, with scholarships and exhibitions widely used as benchmarks of academic success.
In this guide, we profile a handful of the best preparatory schools in this corner of the capital.

Eaton Square Preparatory School, Belgravia
Founded in 1981, Eaton Square Preparatory School began as a nursery, operating from the basement of St Peter’s Church on Eaton Square. It has since expanded into a co-educational independent preparatory school for pupils aged two to 11, now occupying three adjoining Georgian townhouses on nearby Eccleston Square. The school became part of the Dukes Education group in 2018, which provides access to a wider network of independent schools.
Facilities include the Barn library, built using reclaimed materials and designed as a space for reading and independent study to the STEAM Centre, known as the Launch Pad, that supports science and mathematics teaching through interactive projection systems, an augmented-reality sandpit and tablet-based learning walls. Eaton Square is also a TEDx-accredited centre and provides pupils with structured opportunities to develop presentation and public-speaking skills through formal talks.
Academic outcomes form a key part of the school’s profile. In the most recent Year 6 cycle, pupils received 51 offers from senior schools, with 25 acceptances and seven scholarships awarded across academic, creative and sporting categories.
Westminster Under School, Westminster
Westminster Under School is the preparatory arm of Westminster School, established in 1943 to extend the Great School’s academic model to pupils aged 7–13. Historically a boys’ prep, it is transitioning to co-education and will include a pre-preparatory from 2026. Although closely aligned in ethos, the Under School operates from a separate site in Vincent Square, within walking distance of Westminster Abbey and the senior school. Its curriculum is unapologetically academic, structured around rigorous preparation for 11+ and 13+ examinations, while also maintaining a full programme of sport, music and co-curricular activity.
Its results place it among the most academically selective schools in the country. In 2025, 63 of 68 leavers progressed to Westminster School, with three awarded King’s Scholarships; the remaining pupils secured places at Eton, The Perse and City of London School. This pattern is consistent year on year: between 2021 and 2024, the majority of pupils progressed to Westminster, with regular King’s and Queen’s Scholarships awarded, alongside starred Common Entrance passes and awards to Eton, Harrow, St Paul’s and Winchester.
Sussex House, Chelsea
Sussex House School is an independent boys’ preparatory school for pupils aged 8 to 13, founded in 1952 and operating as an independent charitable trust since 1994. It is deliberately small, capped at around 180 pupils and based in a restored Norman Shaw house on Cadogan Square, with additional facilities nearby in Cadogan Street. The school’s structure and charitable status shape its priorities: low staff turnover, small senior forms (averaging around 12 boys) and a tightly focused academic model aimed at preparing pupils for the most selective senior schools via Common Entrance and scholarship routes.
In a typical year, around 80 per cent of leavers progress to schools including Eton, Westminster, King’s College School Wimbledon, St Paul’s and Winchester, with regular academic, music and exhibition awards secured. This performance is underpinned by consistent exam preparation and close professional links between the Headmaster and senior schools. Alongside academics, the school maintains a structured programme in sport and the arts: football and cricket form the sporting core, fencing is a national-level strength and music and drama are well established, with regular performances at venues such as Cadogan Hall and the Fortune Theatre. While the school has a Church of England foundation, it is inclusive in intake, with its ethos centred on academic ambition and long-term pupil retention.
Newton Preparatory, Battersea
Newton Preparatory is a co-educational independent preparatory school in Battersea for pupils aged 3 to 13. Founded in 1991, it has grown into one of South West London’s largest preparatory schools, educating over 600 pupils across nursery through to Year 8. Facilities include a 300-seat auditorium, library, sports halls and outdoor pitches. Academically, the school is strongly focused, with provision tailored to high-ability pupils and a structure designed to support both 11+ and 13+ entry routes.
In 2025, pupils secured 43 scholarships and awards, with 38 per cent of Year 6 and Year 8 leavers receiving recognition across academic, art, drama, music and sport. Offers were made by more than 20 different senior schools, including Alleyn’s, Brighton College, City of London School, Dulwich College, King’s College School Wimbledon and Whitgift.
Dulwich Preparatory & Senior, Dulwich
Founded more than 140 years ago, Dulwich Preparatory & Senior is a long-established independent day school in south-east London, historically known for boys’ education and now operating as a through school following the launch of its senior section in September 2025. Set across 29 acres, the school educates boys from ages two to 16, alongside a co-educational nursery for girls aged two to four. The expansion allows pupils to remain on site beyond Year 8 while continuing to support traditional 11+ and 13+ transition routes to external senior schools.
Facilities are extensive by London standards, supporting a broad academic and co-curricular programme spanning sport, creative arts, music and outdoor education. Between 2020 and 2025, pupils secured more than 350 awards, with 95 per cent progressing to their first-choice senior school. In the most recent leaver cohort, 40 boys collectively achieved 55 awards, representing the strongest results of the past five years.
While preparation for 11+ and 13+ entry remains crucial, schools are adapting to a wider range of senior-school destinations and longer-term planning. Academic results and scholarship outcomes continue to matter, but so does the ability to offer continuity in an increasingly competitive market and provide adaptability when responding to the realities of modern independent education.
