Lightning protection risk assessments

Protect your building, people and operations with a professional lightning risk assessment.

Lightning strikes are unpredictable but the damage they cause isn’t. A structured risk assessment, compliant with BS EN IEC 62305, identifies how vulnerable your site is and what level of protection you legally or practically require. Whether you manage a commercial building, industrial facility or heritage structure, a risk assessment is the first step towards a robust lightning protection system to safeguard your assets.

What does a lightning risk assessment cover?

Our engineers carry out a detailed evaluation of:

strike probability based on location, structure height and surrounding environment

potential consequences including fire, structural damage, equipment failure and operational downtime

existing protection measures and their effectiveness

compliance requirements under BS EN IEC 62305 and insurance obligations

Our assessment process

We offer a tailored service that considers individual business operations, risks, requirements and budget. Our assessments consist of the following steps:

Full site survey

Calculation of risk levels using BS EN IEC 62305 guidance

Identification of required protection measures

Clear, actionable recommendations

Once the assessment is complete, you receive a comprehensive report outlining your site’s risk level, compliance status, recommended protection level (LPS I–IV) and all required system design requirements, including earthing and surge protection.

Our team will discuss the report with you to agree on the next steps. From the risk assessment, the usual next stage is the design of your lightning protection system.
