Lightning Conductor Testing & Inspection
What is lightning conductor testing?
Lightning conductor (lightning protection) testing verifies that a building’s lightning protection system can safely capture, conduct, and disperse a lightning strike into the ground—without damaging the structure, electrics, or occupants.
Testing checks continuity, earth resistance, bonding, fixings, and overall system integrity in line with BS EN 62305 and insurer expectations.
Why Lightning Conductor Testing Matters
Lightning strikes are unpredictable, high-energy events that can cause serious structural damage, electrical failures, fires, and injuries if not properly managed. A lightning protection system is only effective if it is intact, continuous, and correctly earthed — and that can only be confirmed through regular inspection and testing.
Over time, environmental exposure, corrosion, building alterations, and changes in ground conditions can all degrade system performance without visible warning. What looks fine from ground level can fail under strike conditions.
Routine testing ensures the system will perform exactly as designed when it is needed most.
If you are a building owner, facilities manager, landlord, responsible person, or duty holder, the responsibility sits with you. Lightning conductor systems are commonly required on:
- Schools, colleges, and academies
- Hospitals and healthcare premises
- Commercial offices and public buildings
- Warehouses, factories, and industrial sites
- High-rise or exposed structures
- Buildings with rooftop plant, solar PV, or communications equipment
Most insurers require annual inspection and testing, and failure to provide valid certification can lead to voided cover or refused claims.
Who should have it done?
If you own, manage, or insure any of the following, this is not optional—it’s operational hygiene:
- Schools, colleges & academies
- Hospitals & healthcare facilities
- Commercial & industrial buildings
- Warehouses, factories & logistics hubs
- High-rise or exposed buildings
- Sites with rooftop plant, solar PV, or comms equipment
- Any building with an existing lightning protection system
Most insurers require annual inspection and testing—and they will ask for certificates when it matters most (i.e., after an incident).
