Lightning protection under control
Lightning protection system measurements with a report for the building log book
Earth resistance, continuity of connections, condition of air terminals and down conductors, and surge protection in the switchboard. We evaluate the results against the building's documentation — the report is suitable for periodic inspections, insurers, and audits.

The lightning protection system is part of the periodic building inspection under Article 62 of the Polish Building Law (Prawo budowlane) — at least every 5 years, and additionally after roof work or a lightning strike.
Scope
What we test.
- Visual inspection of air terminals, down conductors, and test joints
- Measurement of earth resistance using a method tailored to the system
- Continuity of connections between system components
- Condition of surge protective devices (SPD) in the switchboard
- Compliance with documentation and lightning protection level (LPS)
- Report with results, evaluation, and recommendations
- Repairs: joints, conductors, earth electrodes — upon approval
When to test more often than every 5 years?
- after roof or facade renovation, or PV system installation,
- after a recorded lightning strike or damage,
- when documentation or the LPS class specifies a shorter period.
The PN-EN 62305 series standard recommends more frequent inspections than the statutory minimum for higher protection classes.
Process
A measurement is more than just a number.
- DocumentationProject design, LPS class, previous reports.
- Visual inspectionAir terminals, joints, conductor routing, corrosion.
- MeasurementsEarth resistance and continuity — joint by joint.
- SPDSurge protection in switchboards.
- EvaluationResult against documentation and standard, not just a "bare" number.
- ReportRecommendations, priorities, date of the next test.
Proof
What you get after the test.
- Measurement results per test joint — with location
- Evaluation: complies / does not comply / needs improvement — with justification
- Photos of damage and corrosion, if present
- Repair recommendations with cost estimates
- Next test date in our calendar — we will remind you
- Report prepared for periodic inspections and insurer requirements
Roof, PV, lightning protection — one visit.
After solar PV installation or roof work, the lightning protection system must be checked. We combine lightning protection measurements with an electrical installation inspection.
FAQ
Questions about lightning protection measurements.
How often should lightning protection measurements be carried out?
At least once every 5 years, as part of the periodic inspection of the technical condition of the building under Art. 62 of the Prawo budowlane (Polish Building Law). Building documentation or the LPS protection class may require more frequent testing — we check this before the measurement, not after.
What earth resistance is "good"?
There is no single universal number — the requirement depends on the earthing system, LPS class, and design documentation. Therefore, in the report, we provide the result along with the value required for your facility and a clear assessment.
Is the report sufficient for the insurer?
The report contains the scope, method, results, assessment, and qualifications of the inspector — which is exactly what insurers and inspectors ask for. If the policy specifies additional requirements, we include them in the scope of the test.
What does the price depend on?
On the number of test joints and earth electrodes, the height and accessibility of the roof, and whether the test is combined with other measurements on the facility. We will provide a price range after a brief description of the facility.
B2B Contact
Book lightning protection measurements.
Provide the type of facility, the number of test joints (if known), and whether there has been recent work on the roof — we will propose a date and scope.
Our rule: the result is always accompanied by an assessment against the documentation — a report that stands up to any inspection.
