The Schools continued through the First World War, raising funds for the Red Cross and entertaining wounded soldiers, but at the break of World War II it was decided to take Uplands away from the danger threatening England's channel ports by moving to Monmouthshire.

Meanwhile, in Parkstone, the Sandecotes School was struggling and the Church Education Corporation decided to close it rather than evacuate it to another area.

During the war the School was occupied by the 2nd Battalion the Grenadier Guards and also by American soldiers as they prepared for the D-Day landings.

In 1946 it was decided to move Uplands from Monmouthshire to the vacated Sandecotes buildings.

The top site was sold off and new school buildings were built.
