Lightning Protection Audit Services
Why Singh Isotech's Lightning Protection Audit Services Are Trusted Across India
Most facility managers don’t think about their lightning protection system — until something goes wrong. A single strike to an inadequately protected building can knock out critical equipment, trigger fires, or worse, put lives at risk. That’s where we come in.
At Singh Isotech Pvt. Ltd., we’ve spent years working on-site at factories, commercial complexes, hospitals, data centres, and high-rise buildings across India — checking what’s actually in place versus what should be. It’s hands-on work, not a checkbox exercise. Our certified auditors physically inspect every layer of your protection system, from the lightning rods on the rooftop right down to the earthing pits below ground, and they tell you honestly what’s holding up and what isn’t.
We cover major locations including Gurugram, Delhi NCR, Jaipur, Mumbai, Pune, Chennai, Bangalore, Kolkata, Hyderabad, Lucknow, Ahmedabad, Bhopal, Raipur, Jammu — and anywhere else across PAN India.
Standards We Work To
Our audits aren’t based on guesswork or generic checklists. Every inspection we carry out is grounded in the applicable Indian and international codes:
- IS/IEC 62305: Protection against lightning.
- IS 3043: Code of practice for earthing.
- NBC 2016 — National Building Code of India
- IS 2309: Protection of buildings and allied structures against lightning.
This means our reports hold up with insurers, regulators, and internal safety teams — not just filed away and forgotten.
What We Actually Check
A Complete Rooftop-to-Ground Inspection
A proper lightning protection audit goes well beyond glancing at a lightning rod and calling it done. Our team walks the entire system — top to bottom — and examines every component that plays a role in safely channelling a strike away from your building and its occupants.
This includes:
- Air Terminals (Lightning Rods) — position, condition, and coverage area
- Down Conductors — continuity, routing, and physical integrity
- Grounding and Earthing Systems — resistance levels and pit condition
- Surge Protection Devices (SPDs) — functionality and adequacy for your equipment load
- Bonding Connections — between structural elements, equipment, and the protection system
- Lightning Arresters — type, placement, and current condition
- Structural Elements — anything that could interact with or compromise the system
We also cross-reference your existing layout against the original design documentation and the applicable codes, so any gaps between what was specified and what was actually installed get flagged.

The Equipment We Use ctions
You can’t assess a lightning protection system accurately without the right instruments. Our auditors carry:
- Earth Resistance Testers — to measure whether your earthing system actually meets resistance thresholds
- Clamp Meters — to check current flow in down conductors without having to disconnect them
- Surge Testers — to verify that SPDs will function when a surge hits
- Multimeters — for broader electrical parameter checks across the system
- Soil Resistivity Meters — because the quality of your earthing depends heavily on the ground it sits in
- Infrared Thermography Cameras — to spot hotspots and hidden defects that aren't visible to the naked eye
What You Get from a Lightning Protection Audit
Real Safety Improvements, Not Just a Report
The point of an audit isn’t paperwork — it’s knowing that your building, your equipment, and your people are genuinely protected. Here’s what our clients typically come away with:
Clearer risk picture — You’ll know exactly which parts of your system are working, which are marginal, and which need immediate attention. No vague observations, no jargon for its own sake.
Compliance confidence — If you’re facing an insurance review, a statutory inspection, or an internal EHS/OHS audit, a properly documented lightning protection assessment from a certified team is exactly what you need.
Cost control — Catching a corroded earthing conductor or a failed SPD before the monsoon is far cheaper than dealing with the aftermath of equipment damage or a fire investigation.
Stronger safety culture — Facilities that take lightning protection seriously tend to have better overall safety records. The audit often becomes a starting point for wider EHS improvements.
Who We Work With
Our lightning protection audit services are relevant to a broad range of facilities — any structure with height, rooftop equipment, sensitive electronics, or significant human occupancy needs a properly functioning system. We regularly work with:
- Industrial plants and manufacturing units
- Commercial office buildings and IT parks
- Hospitals and healthcare facilities
- Data centres and telecom infrastructure
- Educational institutions and residential complexes
- Government and public sector buildings
If your facility falls into any of these categories and your last lightning protection inspection was more than a year ago (or never), it’s worth getting in touch.
FAQs
Does my building actually need a lightning protection audit?
If you have rooftop equipment, sensitive electronics, or a tall structure, you really shouldn’t skip this. One direct lightning strike to a poorly earthed building can lead to major equipment losses — the audit cost is nothing in comparison.
How often should a lightning protection system be inspected?
Once a year at minimum — and always after a major storm or building renovation. Singh Isotech follows IS/IEC 62305 and IS 2309 for every check, so you know it’s done properly, not just ticked off a list.
What exactly does the auditor check on my roof?
Everything from lightning rods and down conductors to earthing pits, surge protection devices, and bonding connections. They also test soil resistivity, which a lot of building owners don’t even know matters.
Can an audit report help reduce my insurance premium?
It can, yes. Several insurers offer better rates when you show a certified compliance report. The documentation Singh Isotech provides is detailed enough to hold up with most insurers — worth asking your provider about it.
What does a lightning protection audit cost?
It depends on the size and layout of your building — no two sites are the same. Singh Isotech gives free estimates, so the easiest thing is to call or fill in the inquiry form and get a number specific to your property.
