Lightning Protection & Earthing System Site Audits

Protection systems degrade. Standards evolve. Facilities change. The system that was compliant when installed may no longer meet current requirements — or may have deteriorated to the point where it's no longer performing as intended.

Aetheric conducts comprehensive, independent audits evaluating existing lightning protection, surge protection, and earthing systems against current standards. We deliver a prioritised remediation roadmap — giving you clarity to act with confidence.

• Facility acquisition or transfer — pre-purchase assessment identifying protection adequacy and required capex
• Periodic compliance verification — most standards require inspection at 1–4 year intervals per IEC 62305-3
• Post-incident investigation — identify what failed, why, and how to prevent recurrence
• Regulatory or insurance requirements — independent verification for safety, environmental, or insurance conditions
• Standards update gap analysis — determine impact of revised standards on existing installations
• Pre-design baseline — establish current condition before specifying upgrades

Our audits follow a structured methodology across three phases:

1. Documentation Review

• Existing design drawings, as-built documentation, and maintenance records
• Previous test reports and compliance certificates
• Facility modifications since original installation

2. Field Inspection

• Visual inspection of all accessible LPS components, SPDs, and earthing connections
• Condition assessment of air termination, down conductors, and bonding
• Earthing testing where required — soil resistivity, earth resistance, continuity

3. Gap Analysis & Reporting

• Compliance assessment against current standards (IEC 62305-3, AS/NZS 1768:2021)
• Prioritised findings — critical, high, medium, low
• Remediation recommendations with cost estimates, feeding into design services
