Do I legally need a lightning protection system?

If your building’s risk assessment (as defined in BS EN 62305) indicates a requirement, then yes — lightning protection becomes a compliance obligation. Many commercial insurers also require certified systems for cover to remain valid.

How often should a lightning protection system be tested?

UK standards recommend annual testing to ensure the system remains safe, effective, and compliant. High‑risk or exposed sites may require more frequent inspections depending on environmental conditions.

What does a lightning protection inspection include?

A full inspection covers continuity testing, earth resistance measurements, visual checks of air terminals, down conductors, bonding, and surge protection devices. You receive a detailed compliance report and certification.

Can you upgrade or repair an existing lightning protection system?

Yes. We carry out remedial works, system upgrades, and compliance corrections to bring older or damaged systems up to BS EN 62305 standards.

Do you provide surge protection as part of the service?

Absolutely. Surge Protection Devices (SPDs) are a critical part of a compliant system. We install coordinated SPDs to protect electrical systems, data networks, and sensitive equipment.

Are your engineers certified?

All CDL engineers are trained and certified to work to BS EN 62305, with extensive experience in lightning protection, earthing, and surge mitigation.

Do you work on commercial, industrial, and residential properties?

Yes. We support all building types including commercial premises, industrial facilities, residential developments, heritage buildings, and high‑risk environments.

Do you offer nationwide coverage?

We operate across the UK with rapid response teams available for surveys, installations, testing, and emergency callouts.

How long does a lightning protection installation take?

Most installations are completed within 1–3 days depending on building size and complexity. Larger commercial or industrial sites may require longer.

Can you provide documentation for insurance or compliance audits?

Yes. All work includes full certification, test results, and compliance reports suitable for insurers, facility managers, and regulatory audits.
