Lightning Protection Inspection & Testing

Lightning Protection Inspection & Testing

Lightning Strikes hit the ground approximately 300,000 times each year and are responsible for various types of damage both Financial and Physical, for example:

• Fire
• Structural Damage
• Power surge to electrical equipment
• Electrocution

The Electricity at Work Regulations 1989 state that lightning protection systems should be tested in accordance with the relevant British Standard (which will be either BS 6651:1999 or BS EN 62305:2006, depending upon when the system was installed).

A system which is not properly maintained might not be effective in discharging lightning safely to ground or prevent over currents and overvoltages from damaging electrical systems and equipment. As such, we recommend seasonal testing to be carried out in order to ensure the system is checked at different times throughout the year to compensate for temperature and condition changes, an 11 month testing schedule is advised.

McLennan inspection and testing engineers are fully competent in undertaking the detailed inspection and testing of all lightning protection systems. Certificates of inspection detailing our findings, plus details of any repairs required to return systems to a serviceable condition will be provided on completion of the Lightning Protection checks.
