Wessex Archaeology

What Wessex Archaeology does

Wessex Archaeology is a UK-based archaeological and heritage services organisation structured as a company limited by guarantee and registered charity (No. 287786). Founded in 1979 and headquartered in Salisbury, the firm provides a comprehensive suite of archaeological and heritage services spanning excavation and mitigation, heritage consultancy, marine and maritime archaeology, diving investigation, marine geophysics, heritage interpretation, and post-excavation research. It serves commercial developers and housebuilders, infrastructure and construction firms, energy developers (notably offshore wind), national heritage agencies such as Historic England, local authorities, and the Ministry of Defence, with named enterprise clients including Ørsted, E.ON, Atkins, and DP World London Gateway.

The firm's service portfolio is unusually broad for the sector, combining traditional fieldwork (excavation, watching briefs, walkover and topographic surveys, historic building recording) with specialist capabilities (geoarchaeological deposit modelling, osteoarchaeology, zooarchaeology, conservation, scientific dating) and an advanced data-collection stack (LiDAR, photogrammetry, laser scanning, UAV surveys, structured light scanning, reflectance transformation imaging). A creative studio division delivers VR/AR experiences, 3D reconstructions, animation, exhibition design, and GIS-based storytelling via ArcGIS StoryMaps. The firm holds CIfA accreditation and BSI Quality Management certification, both gating credentials for UK planning-condition work and public-sector tenders.

Revenue is generated through project-based professional services contracts with enterprise and government clients, delivered through six UK offices (Salisbury, Amesbury, Meopham, Sheffield, Bristol, Edinburgh) and wholly-owned Trident Archeologie subsidiaries in Rotterdam and Rostock. Pricing is project-scoped rather than standardised, with multi-year contracts typical for major infrastructure engagements such as High Speed 1 (2000–2003) and the Viking Link Interconnector. Approximately 350 staff across diverse heritage specialisms underpin delivery capacity.
