Certificate of Compliance

HVC Lightning Protection: The Smart Choice for Thatch Roofs and Aesthetics-First Properties

A lightning protection system is only as good as its documentation. Insurers, auditors, property buyers and regulatory authorities all ask the same question: can you prove your system is compliant?HHK's Certificates of Compliance answer that question. Each one is issued after rigorous testing and inspection.

It is a legally recognised document confirming that your lightning protection and earthing systems meet or exceed the requirements of SANS 62305, SANS 10313, SANS 10199 and related standards.

It gives you the evidence to satisfy insurers, pass audits and transfer property. Just as important, it lets you know that the people and assets in your care are properly protected.

What a Certificate of Compliance Covers

An HHK Certificate of Compliance is not a generic letter. It is a detailed, system-specific document that records:

Full system description, including type, class and level of protection
Results of all continuity, resistance and insulation tests performed
Earth resistance values at each electrode and for the overall system
Confirmation that all components comply with the relevant SANS/IEC material and performance standards
Details of the installation contractor and the qualified person responsible for certification
Date of installation or inspection, with a record of the test equipment used
Statement of compliance with specific standards (SANS 62305-3, SANS 10199, SANS 10313, etc.)

When Is a Certificate of Compliance Required?

New Installations

Every new lightning protection or earthing system HHK installs is issued with a Certificate of Compliance as standard.

It is not an optional extra. It is part of the service. On completion, our qualified technicians carry out a full suite of acceptance tests and document the results.

The certificate is your proof that the system was installed correctly and performs as designed.

Property Transactions

When commercial or industrial property is bought or sold, a valid Certificate of Compliance for the lightning protection system gives both parties assurance and can be made a condition of the sale.

We provide compliance inspections and certification as part of pre-purchase due diligence.

Existing Systems: Compliance Verification

If you have inherited a building with an existing lightning protection system, or your current system hasn’t been tested in years, HHK can carry out a compliance verification inspection.

We test every component against current standards and identify any deficiencies.

If the system passes, we issue a Certificate of Compliance. If it doesn’t, you receive a detailed remediation report.

Maintenance and Periodic Re-Certification

A Certificate of Compliance is not a once-off document. Lightning protection systems deteriorate over time.

Conductors corrode, connections loosen, earth electrodes degrade, and building modifications can compromise protection.

SANS 62305-3 requires lightning protection systems to be inspected at regular intervals, annually for most structures and more often for high-risk facilities.

Insurance and Audit Requirements

Insurers increasingly ask for documented proof of lightning protection compliance as a condition of cover.

This is most common for high-value industrial facilities, data centres and buildings in high-lightning-risk regions.

An HHK Certificate of Compliance is accepted by all major South African insurers and meets the documentary requirements of ISO, OHS and other management system audits.

Why HHK Certification Matters

Signed by qualified professionals with decades of lightning protection experience.
Based on actual test results, not visual inspection alone
Recognised by insurers, auditors and regulatory bodies throughout Southern Africa
Supported by our reputation as the region’s largest lightning protection specialist
Backed by our foundational role in ELPA and involvement in SANS standards committee.

In lightning protection, documentation isn’t bureaucracy. It’s accountability. An HHK Certificate of Compliance means a qualified specialist has tested and verified your system, and stands behind it.

Common Applications

New lightning protection installations for commercial, industrial, and residential buildings
Retrofit and upgrade of existing down conductor systems that no longer meet current standards
High-rise buildings requiring multiple parallel down conductors for current sharing
Explosive atmosphere zones in petrochemical and mining environments, where spark-free, high-integrity routing is essential
Thatch roof protection using HVC insulated down conductors
Infrastructure projects: bridges, telecommunication towers, wind turbines, solar farms

Every HHK installation includes a full test report and a legally recognised Certificate of Compliance — essential for insurance purposes and regulatory audits.
