Frequently Asked Questions About Cathodic Protection & BS EN ISO 15257

Answers to the most common questions we receive about cathodic protection, BS EN ISO 15257 competence levels, and our consultancy services.

BS EN ISO 15257 is the international standard defining competence levels for personnel working in cathodic protection (CP). Level 5 — Cathodic Protection Expert is the highest level recognised within the standard. It is awarded to practitioners with proven expertise in the design, management, and innovation of CP systems within a defined sector, such as reinforced concrete structures. Level 5 status is held by very few professionals worldwide.

Both Level 4 and Level 5 are fully competent to design, validate and advise on complex, high-consequence CP projects within their sector — BS EN ISO 15257 clause 4.6 confirms that Level 4 persons are not precluded from any task attributed to Level 5. Level 5 additionally recognises breadth across application sectors and demonstrated contribution to the advancement of CP science and practice.

Yes. SegCorr offers independent third-party review, validation, and verification of cathodic protection and corrosion management designs. Reviews are carried out by an BS EN ISO 15257 Level 5 CP Expert for reinforced concrete, and a Level 4 Specialist across all other sectors. This service provides asset owners, contractors, and engineers with authoritative assurance that designs meet international standards and project-specific requirements.

SegCorr provides cathodic protection and corrosion management services across all four BS EN ISO 15257 sectors: reinforced concrete, buried structures, immersed structures, and internal surfaces of metallic equipment. Typical assets include highway and railway bridges, car parks, marine and coastal structures, tunnels, heritage concrete, pipelines, storage tanks, and industrial process plants — both in the UK and internationally.

Yes. Cathodic protection is one of the most effective long-term solutions for arresting and controlling reinforcement corrosion in existing concrete structures. Both impressed current (ICCP) and galvanic (sacrificial) systems can be retrofitted to bridges, car parks, marine structures, and buildings. A correctly designed CP system can extend asset life by decades, often at a fraction of the cost of full reinforcement replacement.

Yes. SegCorr provides expert witness, technical advisory, and dispute resolution services for legal teams, insurers, and asset owners dealing with corrosion-related claims, CP system failures, and design disagreements. Reports and testimony are delivered by a Chartered Engineer holding BS EN ISO 15257 Level 5 CP Expert status for reinforced concrete and Level 4 Specialist competence across all CP sectors — providing the highest level of technical authority.

SegCorr provides independent CPD-accredited online CP and corrosion training, in-person industrial presentations, and university teaching. Our two online courses — Corrosion Protection of Steel in Concrete (20 hours) and Fundamentals of Design for CP of Steel in Concrete (50 hours) — are developed and delivered by a BS EN ISO 15257 Level 5 certificated CP Expert who is a Visiting Lecturer at the Universities of Leeds and Birmingham and formerly a tutor and examiner on ICorr’s own CP courses.
