A direct lightning strike or indirect overvoltage event can cause catastrophic structural damage, destroy critical electrical and electronic systems, start fires, and create life-threatening hazards for building occupants and maintenance personnel. Lightning strikes the United Kingdom approximately 300,000 times per year. The risk is not theoretical and the compliance obligation is clear.
A correctly designed, installed, and maintained lightning protection system — specified to BS EN 62305, the UK and European standard for protection against lightning — provides a controlled, low-impedance path to earth for lightning energy, protecting the structure, its contents, and the people within it. For facilities managers, building owners, asset managers, and principal contractors, a compliant and certified lightning protection system is a fundamental component of a building’s overall risk management and compliance framework.
The absence of a tested and certified lightning protection system can invalidate insurance, breach statutory duties, and expose duty holders to serious legal liability. CCR Maintenance Ltd provides a complete lightning protection service — from initial risk assessment through to certified installation, scheduled inspection, and ongoing maintenance — all delivered within our ISO 9001 quality management system and under ISO 45001 occupational health and safety procedures.
COMPLIANCE & INSURANCE RISK
An untested or non-compliant lightning protection system may not be recognised by insurers following a lightning event. The absence of a current inspection certificate may constitute a breach of your duty of care under health and safety legislation. CCR Maintenance Ltd issues fully documented inspection certificates and earth resistance test results following every inspection.
The BS EN 62305 standard series is the definitive framework for lightning protection in the UK, replacing the former BS 6651. CCR Maintenance Ltd designs, installs, inspects, and certifies to all four parts of this standard:
Standard | Full Title | Scope |
BS EN 62305-1 | General Principles | Defines the characteristics of lightning and its effects, and establishes the basis for the standard series. |
BS EN 62305-2 | Risk Management | Methodology for assessing the risk from lightning to a structure and determining the Lightning Protection Level (LPL) required. |
BS EN 62305-3 | Physical Damage & Life Hazard | Covers the design, installation, inspection, and maintenance of the physical lightning protection system (LPS) — air termination, down conductors, earth termination. |
BS EN 62305-4 | Electrical & Electronic Systems | Covers protection against lightning electromagnetic impulse (LEMP) and the specification of surge protective devices (SPDs). |
IEC 62305 | International Standard | The international counterpart to BS EN 62305, forming the basis of the UK standard. CCR Maintenance Ltd operates to both frameworks. |
BS EN 62305-2 defines four Lightning Protection Levels (LPL I to IV), each with corresponding interception efficiency requirements and inspection intervals. CCR Maintenance Ltd designs and certifies to all four levels.
LPL Class | Risk Level | Typical Structure Types | Interception Efficiency | Inspection Interval |
LPL I | Highest risk | Explosive/flammable storage, munitions, fuel depots, nuclear facilities, critical national infrastructure | 98% | Visual: 12 months | Full test: 12 months |
LPL II | High risk | Hospitals, data centres, chemical plants, high-rise buildings, critical systems facilities | 95% | Visual: 12 months | Full test: 24 months |
LPL III | Medium risk | Commercial offices, industrial premises, schools, hotels, multi-storey residential | 90% | Visual: 24 months | Full test: 48 months |
LPL IV | Lower risk | Lower-risk commercial and industrial structures meeting specific BS EN 62305-2 criteria | 84% | Per risk assessment — typically 48 months |
Note: CCR Maintenance Ltd recommends annual inspection for all commercial and industrial structures as best practice under our ISO 9001 quality management programme
