The school is located in Chase Side, Southgate, and Green Road, Oakwood, both in North London.

In 1917, with World War I ongoing, and the advent of Zeppelin raids, it was decided that the school could not operate in Hornsey and the Deakin sisters took the students to their country residence, Salcombe House, in Devon.

In 1918, upon returning to London, the sisters relocated their school to Avenue Road in Southgate close to the current site on Chase Side.

The school was acquired by Asquith Court group in 1990 and the first headmaster was appointed - Anthony Blackhurst.

In 1998, the school needed to expand and the Green Road site was acquired for the lower years.
