Welcome to Cumnor House Sussex

Cumnor House Sussex is one of the country’s leading independent day and boarding schools for 2-13 year-old boys and girls. Situated in Mid-Sussex, in the village of Danehill, the School is centrally located for travelling within Sussex and is within easy reach of London by both rail and car.

From the Nursery (2-4 year olds), through to the Pre-Prep (4-8 year olds) and Prep School (8-13 year-olds) we provide a safe and unhurried childhood for active and ambitious children. Each child is given the opportunity to learn in state-of-the-art facilities; form close friendships within a nurturing, family environment; explore their surroundings and climb trees within our 65-acre site in the heart of the Ashdown Forest.

Specialist teachers pride themselves on tapping into each child’s individual talent, encouraging and enabling them to reach their personal potential both inside and outside the classroom. The range of leading senior independent schools that our children move on to, and the number of Scholarships and Awards achieved, is testament to their ability to succeed.

In 2017, 49 children moved on to 21 different senior schools, having achieved 31 Awards and Scholarships across Academic, All-Rounder, Drama, Equestrian, Music, Leadership and Sport, and 100% success rate in passing Common Entrance to their first choice of senior school. Similar success was achieved in 2016 when 50 children moved on to 18 different senior schools and secured 33 Awards and Scholarships in Academic, Art, Drama, DT, Music, Leadership and Sport.

The Cumnor House Sussex motto - "Aim High, Be Kind, Dare to be Different" - encourages us to seek the best in, and for, each individual child during their time with us and as we help shape their core values for life beyond school.

Headmaster's welcome...

"At Cumnor House we seek to educate children in the fullest sense. We aim for academic excellence, certainly. Indeed, we expect our children to set themselves high standards in everything they undertake."

But there is so much more. We are privileged, through our excellent facilities, to be able to expose them to a wealth of opportunities that will allow them to discover their talents and tastes. They will form friendships and begin to understand the intricacies of human relationships. And they will make mistakes and learn from them in a secure and supportive environment.

If you are an existing member of the Cumnor community, then delve into relevant sections of this website. If you are coming to this afresh, as a prospective parent, as someone seeking to gain an insight into the world of a prep school – of Cumnor House, in particular – then I hope that you will be tantalized by brief introductions to what we offer and contact us to make an appointment to visit.
