Before 1945 there was no National Health Service and people had to pay for their own medical treatment.
In 1923 the Revd W R Martin-Leake decided the school should raise the money to buy and support a child's cot at King's College Hospital. In 1923 the school marched to King's for a service to dedicate the cot, which was held by the Chaplain of King's College Hospital, an Alumni of the Prep, 
The magazine of 1923 records that the school "paid for and supported the cost of a bed at King’s Hospital for which it was necessary to raise the sum of £20 a term which was done by a levy of 1/- from each boy each term. The Upper and Middle schools attended the Dedication Service on June 24th 1923 when the bed was dedicated in the Chapel of the hospital by the Chaplain, Revd R V Galer, an Old Boy of DCPS."
