In May 1947, a 13-acre (53,000 m2) sports centre was opened at Beckenham and in May 1949 employees were accorded full membership rights.
The SSCS registered office was at 99 London Road, Croydon, Surrey, where it remained until it merged with the Co-operative Wholesale Society on 28 July 1984.
The London Road offices closed on 17 May 1985 and moved to 18 Blackhorse Lane, Addiscombe until later that year.
The merger with CWS saw the SSCS operating shops and services over an area of 400 square miles (1,000 km2) of eastern Surrey and western Kent.
In its last full trading year, the SSCS had a turnover of £47m, share capital of £1.7m, membership of 167,000, and 1,100 staff.
