Lightning Protection

Professional Lightning Protection Services

Electrical Testing UK designs, installs, and tests lightning protection systems for commercial, industrial, and public sector buildings. Lightning strikes can cause structural damage, fire, and equipment failure, while nearby strikes can induce harmful voltages in electrical systems.

We carry out risk assessments to BS EN 62305, design systems to suit the building and risk level, and install and test them to meet certification and insurance requirements.

How Our Service Works

Lightning Protection for Commercial, Industrial, & Public Buildings

We provide complete lightning protection solutions, from risk assessment and design to installation and ongoing testing, tailored to each structure and environment.

Risk assessments: We assess lightning risk to BS EN 62305-2, considering structure, location, and occupancy to determine required protection levels.
External protection systems: Design and installation of air termination, down conductors, and earthing systems to BS EN 62305-3.
Industrial and high-risk sites: Protection for chimneys, tanks, and hazardous environments, including correct bonding of equipment and pipework.
Internal surge protection: Installation of coordinated SPDs to protect electrical and data systems from induced voltages.
Annual inspection and testing: Yearly testing of system continuity, resistance, and connections, with certification provided.
Heritage and listed buildings: Discreet system design using concealed conductors and compliant fixing methods.

Lightning Protection: FAQs

How is the need for lightning protection assessed?
We carry out a risk assessment to BS EN 62305-2, considering the building’s structure, location, occupancy, and systems to determine the required level of protection.

How is the system designed?
We produce a full design covering air termination, down conductors, earthing, bonding, and any required surge protection, with detailed drawings before installation begins.

How is the system installed and tested?
Our qualified engineers install the system to BS EN 62305, ensuring correct routing, bonding, and earthing. The system is then tested and commissioned with certification issued.

Is ongoing inspection required?
Yes. We carry out annual inspections and testing, checking all components and issuing a certificate to confirm continued compliance and meet insurance requirements.
