In 1939, at the outbreak of war, the school was evacuated to Whatcombe House in Dorset. Unfortunately the evacuation was unsuccessful, only lasting about one term. The conditions, including cooking facilities, were far from ideal and the bombing in the Hampstead area of London was not as bad as expected, so many parents wanted their children back home with them. Following the short evacuation, the school was forced to close and reopened again in 1945, following repairs to the building caused by war damage.
