Part of: Lightning Protection Testing
Section 5 of Electricity at Work Act 1989 states that all lightning conductors and earth grounding installations should be visually inspected and tested at regularly fixed intervals, preferably not exceeding 12 months.
We recommend the interval should be slightly shorter than one year in order to vary the season in which testing takes place over time. This counters the effect of ambient temperature and other seasonal factors on readings from the installation. We record all test conditions and results, and a reminder is sent out before the next test is due.
