The story
Founded in 1979 as the Wessex Archaeological Committee, its name was changed in 1983 to the Trust for Wessex Archaeology. It was one of the first rescue archaeology units in the country, focussing on the numerous sites in and around Salisbury Plain. In 2005, it was renamed Wessex Archaeology Limited, trading as "Wessex Archaeology".
Since the advent of developer-funded archaeology with PPG 16 and its successor, PPS5, it has expanded its commercial operations across the UK with offices in Gravesend and Sheffield. WA opened its Scottish office in Edinburgh in 2010. It includes a large marine archaeology department. Further regional offices were opened in Welshpool and Bristol in 2014.
