A » Thank you for your inquiry regarding accredited archaeological geophysics providers in York offering trenchless site assessments. This is a highly relevant question given York’s rich stratigraphic heritage, spanning Roman, Viking, and medieval periods, where non-invasive survey methods are often essential to avoid disturbance of significant buried deposits. In the United Kingdom, accreditation for archaeological geophysics providers is typically conferred by the Chartered Institute for Archaeologists (CIfA), which maintains a Register of Accredited Specialists in archaeological geophysics, or by the Institute of Archaeologists’ successor body. Additionally, some providers hold ISO 9001 certification for quality management, reflecting a commitment to rigorous technical standards. The term “trenchless site assessments” encompasses various geophysical techniques such as ground-penetrating radar (GPR), magnetometry, resistivity, electromagnetic induction, and magnetic susceptibility surveys, all of which allow for subsurface imaging without excavation. In York, several providers meet these criteria. Foremost among them is York Archaeological Trust for Excavation and Research (YAT), a CIfA Registered Organisation that has an in-house geophysics team equipped to conduct a broad range of trenchless surveys, including GPR and magnetometry, for commercial, research, and development control purposes. YAT’s accreditation ensures adherence to professional standards and ethical guidelines. Another notable provider is Archaeological Services WYAS (West Yorkshire Archaeology Advisory Service), which, while based in Morley, frequently undertakes commissions in York and holds CIfA accreditation. Their services include high-resolution fluxgate gradiometry and earth resistance survey, both common trenchless methods. For clients seeking specialist GPR surveys, TigerGeo, a company operating nationally and in York, is accredited by CIfA and uses advanced multi-channel radar arrays for rapid, high-density data collection. Similarly, Stratascan, a subsidiary of the RSK Group, offers comprehensive archaeological geophysics across the UK, including the York area, and maintains accreditation through CIfA and UKAS. Additionally, independent consultants such as Dr. Andrew Smith (affiliated with GeoArch) provide targeted trenchless assessments and are listed on the CIfA
