UKCSS™ Operational Standards for Approved Scanners

A UKCSS™-approved scanner is not just a technician with a machine. It is a practitioner who meets a clearly defined, auditable, and enforceable set of standards. These standards separate competent professionals from untrained operators – and give clients confidence that work is being carried out safely and consistently.

1. Technical Competence

• Completion of UKCSS™-recognised training across GPR, ultrasound, covermeters, and rebound hammers
• Demonstrated logged experience under supervision before independent practice
• Ongoing CPD and refresher assessments every two years to maintain competence

2. Equipment Standards

• Use of equipment that meets UKCSS™-defined minimum performance specifications
• Annual calibration of all devices with records held in a central register
• Daily functionality checks on site to verify equipment performance before scanning

3. Methodology and Process

• Pre-scan review of drawings, risks, and client objectives to define scope and acceptance criteria
• Systematic scanning protocols with defined line spacing and orientations to ensure repeatability
• Use of complementary tools (e.g. covermeters, EM locators) for verification where required
• Standardised reporting templates that clearly state findings, limitations, and confidence levels
• Full chain of evidence from raw data through interpretation to final reporting

4. Safety and Professional Conduct

• Full integration with site H&S systems, permits to work, and live service protocols
• Methods must not compromise the integrity of the structure being assessed
• Findings reported impartially, free from commercial or contractor pressure

5. Client Confidence

• Reports written in plain, unambiguous language supported by diagrams and annotated drawings
• Defined liability statements included in every report to make scope and responsibility transparent
• Clear communication of technology limitations so clients understand risk and certainty

6. Ethics and Accountability

• Zero tolerance for fabricated data, incomplete scans, or unsafe practices
• Mechanism for reporting malpractice, with independent oversight
• Breaches result in immediate suspension or removal from the Register

7. Innovation and Future-Proofing

• Technology-neutral approach – any equipment or method may be used if it meets UKCSS™ performance criteria
• Digital outputs provided in formats suitable for BIM and asset management systems
• Commitment to minimising repeat surveys, wasted effort, and environmental impact
