Lightning Protection

Speak To Us About Your Project

Lightning Protection Systems

Evans Electrical designs, installs and maintains lightning protection systems that safeguard people, buildings and critical electrical infrastructure from the effects of lightning strikes and transient overvoltages. Our approach is grounded in technical accuracy, regulatory compliance and a strong focus on safety and risk management.

Lightning protection is a critical element of a building’s overall electrical safety strategy. Incorrectly designed, poorly installed or inadequately maintained systems can leave buildings exposed to serious risks, including fire, structural damage, equipment failure and operational downtime. We deliver lightning protection solutions that are engineered to perform reliably and remain compliant throughout their operational life.

Risk Assessment and System Design

Effective lightning protection begins with a thorough understanding of risk. We undertake detailed assessments to determine the appropriate level of protection required, considering factors such as building construction, height, occupancy, usage, surrounding structures and the presence of sensitive electrical or electronic equipment.

Our lightning protection design services include:

Risk assessment in accordance with current standards
Air termination networks (rods, tapes and meshed systems)
Down conductor routing and segregation
Earth termination and earthing system design
Bonding of metallic services and structures
Surge Protection Devices (SPDs) for internal systems

Systems are designed to safely intercept lightning strikes and conduct energy to earth while minimising the risk of side-flashing, dangerous touch voltages and damage to internal services.

Installation and Workmanship Standards

The performance of a lightning protection system depends heavily on installation quality. Our experienced teams install systems in strict accordance with approved designs, standards and manufacturer requirements.

Careful attention is given to conductor routing, fixings, joint integrity, corrosion resistance and interface with other building elements. Where systems are installed on existing buildings, works are carefully coordinated to maintain building integrity and minimise disruption.

All installations are subject to structured quality checks to ensure continuity, mechanical security and electrical performance before handover.

Integration with Earthing and Electrical Systems

Lightning protection systems do not operate in isolation. Effective performance relies on correct integration with the building’s earthing and bonding arrangements and wider electrical infrastructure.

We coordinate lightning protection works with:

Main earthing systems
Protective equipotential bonding
Electrical distribution systems
Surge protection within LV and data networks

This integrated approach reduces the risk of dangerous potential differences and protects sensitive electrical and electronic equipment from transient overvoltages caused by lightning activity.

Inspection, Testing and Certification

Regular inspection and testing are essential to ensure lightning protection systems remain effective over time. Environmental exposure, building alterations and corrosion can all degrade system performance if left unchecked.

We provide:

Initial verification and certification
Periodic inspection and testing
Reporting on system condition and compliance
Remedial works and system upgrades where required

Testing confirms continuity, earth resistance and overall system integrity, providing assurance that protection remains effective and compliant.

Health & Safety in Lightning Protection Works

Working on lightning protection systems presents specific health and safety challenges, particularly where works are undertaken at height or in proximity to live electrical systems.

We manage these risks through robust health and safety procedures, including:

Detailed risk assessments and method statements
Safe systems of work for working at height
Permit-to-work controls where required
Electrical isolation and verification procedures
Competency management and training

Our teams are trained to identify hazards, follow strict safety controls and work responsibly to protect themselves, building occupants and the integrity of the structure.

Long-Term Compliance and Asset Protection

Lightning protection systems must remain effective for the lifetime of the building. We design systems with durability, accessibility and maintainability in mind, supporting long-term compliance and ease of inspection.

Clear documentation, as-installed drawings and certification form part of the handover process, enabling clients to manage ongoing inspection regimes and demonstrate compliance with regulatory and insurance requirements.

Why Evans Electrical?

Why choose Evans Electrical for lightning protection systems?

We deliver lightning protection systems that are correctly designed, safely installed and fully integrated with wider electrical infrastructure, ensuring long-term safety and compliance.

How do you ensure systems meet current standards?

All designs, installations and inspections are carried out in line with current lightning protection standards, supported by testing, certification and detailed documentation.

Do you inspect and upgrade existing systems?

Yes. We assess existing lightning protection systems, identify non-compliance or deterioration and deliver upgrades to meet current requirements.

How do you manage safety during installation and testing?

We follow strict health and safety procedures, including working-at-height controls, permit systems and electrical safety protocols.
