Women who had trained under Hill formed the Association of Women Housing Workers in 1916. This later changed its name to the Society of Housing Managers in 1948. After merging with the Institute of Housing Managers in 1965, the society became the present day Chartered Institute of Housing in 1994. The CIH is a professional body for those working in the housing profession in the UK and overseas. The training that Hill gave to Charity Organisation Society volunteers contributed to the development of modern social work, and COS continued to be instrumental in developing social work as a profession during the twentieth century. COS is still in operation today as the charity Family Action.
