Regional players

• York Archaeological Trust: Independent archaeological trust operating across northern England with field services, post-excavation, and a publication program. Comparable to TVAS in service mix but primarily regional to the north, so not a head-to-head competitor in TVAS's core southern territory.
• Cambridge Archaeological Unit: University-affiliated archaeological unit providing fieldwork, research, and publication services. Comparable to TVAS's academic and publication activity, though primarily regional to the east of England and Cambridge area rather than competing directly in southern England.
