1933 - 1975

The Home remained at Westcroft Farm until 1933, when urban development and a compulsory purchase order forced moves to Boreham Wood, Hertfordshire (1933-1975) and finally in 1971 to Speen Farm in the Chiltern Hills between High Wycombe and Aylesbury, in Buckinghamshire. The sale of the Boreham Wood site for housing development allowed a new Westcroft Stables complex, including 85 loose boxes, to be built at Speen Farm and officially opened on 15 July 1975.

During the First World War The Home provided the prototype, motorised horse ambulance to help the evacuation of wounded horses from the front line in France. While the number of London cab horses declined, there were still thousands of tradesmen's horses requiring help and The Home provided rest and recuperation for hundreds of horses a year.

By the mid-1960s, the number of working horses depending on it was continuing to decline. The Committee decided therefore to extend The Home's activities. With the blessing of the Charity Commission, it was agreed that a charitable foundation would be established with the purpose of giving grants to other charitable organisations concerned with the welfare of horses.
