Lightning Protection Systems Testing

Your building’s lightning protection systems testing is a critical aspect when it comes to property management.

Lightning conductor systems must function correctly, without fail, each and every time they’re called into action.  As lightning strikes aren’t particularly predictable, permanent readiness is a pre-requisite.

Work regulations insist that lightning conductor protection systems are tested every 12 months in accordance with British Standards - you and/or your clients needs to comply to remain safe.

We installed multiple down conductor tapes to this refurbishment project, coordinating our works between the main contractor, the roofing contractor and ground works contractors.

What Is The Frequency For Lightning Protection System Testing?

According to the regulations...it should be inspected every 12 months.

However for true overall accuracy - tests should be carried out in all weather scenarios. 11 month inspections help with this.

11-Monthly Inspections For Accuracy

Why is it suggested that 11-monthly inspections are better?  As a minimum they must be tested in accordance with the relevant British Standard, in accordance with The Electricity at Work Regulations 1989 - either BS 6651:1999 or BS EN 62305. They state the maximum period between inspections should be twelve months. 

How Fluctuating Ground Conditions Affect Test Results

Due to different climatic conditions different earth resistance reading levels can easily arise. In hotter months with dryer ground a system could fail!, indicating the prior test results were 'distorted'. The same system may pass in wetter ground conditions several months later.

How come?!  In reality the results differ as the weather and ground conditions change. Dryer ground conditions lead to reduced conduction between the lightning rod and the earth and the earth doesn't dissipate the energy quickly. (When testing the system this shows as a higher earth resistance reading).

So for the months when the system is likely to pass, the building, mains electrical equipment and people will be protected from danger, but for the hotter months when the system is less likely to function properly there are some geniune serious and unseen dangers (unseen to those who don't understand the underlying issues).


Having them tested at eleven month intervals provides a more accurate and comprehensive report over time and is your best chance of ensuring the building, mains electrical equipment and people remain safe.

The initial lightning protection system test should be thorough and detailed in accordance with BS 6651 / BS EN 62305, with the following years taking less extensive visual inspections.
