Earthing and lightning protection system assessments from visual inspection against applicable standards to a full condition assessment including all necessary tests to give you an up to date review of its present condition. The technical standards (BS EN 50522, ENATS 41-24, BS EN 62305) recommend periodic assessment of earthing and lightning systems, particularly for sites associated with a high earth potential rise, larger numbers of people, sites at risk of copper theft or those with hazardous or explosive atmospheres.
