When lightning strikes or power surges threaten your property, proper surge protection installation can mean the difference between normal operations and catastrophic equipment failure. At Lightning Protection Testing UK, we specialise in comprehensive surge protection systems that safeguard your electrical equipment, data systems, and critical infrastructure from devastating transient overvoltage events.
Professional surge protection installation involves fitting specialised surge protection devices that detect dangerous voltage spikes and safely divert excess electrical energy to earth, protecting your valuable equipment and systems. Our surge protective devices work as the first line of defence against lightning-induced currents and power grid disturbances that can destroy sensitive electronic equipment in milliseconds.

Professional installations create multiple layers of defence throughout your electrical installation. We install different types of protective devices at strategic points, from your main incomer to individual pieces of equipment, ensuring comprehensive coverage against voltage surges of all magnitudes.
We install Type 1 surge protective devices at your main incomer to handle the largest surge currents from direct lightning strikes. These robust devices can manage currents exceeding 25kA, providing the primary defence for your entire electrical installation. Type 1 units are essential for buildings with external lightning protection systems or those in high-risk areas.
Type 2 surge protective devices protect sub distribution boards throughout your building. We strategically position these units to catch residual surges that pass through Type 1 coverage, ensuring that voltage spikes cannot reach downstream electrical equipment. These installations are crucial for protecting motors, transformers, and other valuable electrical devices connected to your distribution systems.
For your most sensitive electronic equipment, we install Type 3 units directly at the point of use. These final-stage protectors defend computers, servers, telecommunications equipment, and other critical systems from smaller but potentially damaging voltage fluctuations that could affect their operation or cause gradual failure over time.
Our service covers every aspect of your electrical installation. We protect main electrical panels, sub distribution boards, and individual circuits that power your critical operations. Our installations comply with BS EN 62305-4 standards and integrate seamlessly with your existing electrical infrastructure.
We understand that different types of electrical installations require specific strategies. Industrial facilities with heavy motors and transformers need robust coverage at multiple levels, while commercial buildings with extensive computer systems require tailored approaches for sensitive equipment needs.
For commercial and industrial premises with three-phase electrical systems, we install devices that protect all phases simultaneously. Our work ensures balanced coverage across your entire electrical installation, preventing damage to motors, industrial equipment, and three-phase distribution boards.
Beyond electrical systems, we provide protection for telephone lines, internet connections, and data networks. Lightning strikes can induce dangerous surges in these low-voltage lines, potentially destroying computers, servers, and communications equipment.
Our data protection service includes coverage for ethernet cables, telephone lines, CCTV systems, and building management technologies. We ensure that surge currents cannot enter your premises through any pathway, protecting both your electrical equipment and your vital data systems.
We install devices for various communication technologies, including fibre optic lines, coaxial cables, and control system wiring. Each different type of line requires specific coverage designed for its voltage levels and signal characteristics.
Every installation begins with a comprehensive risk assessment of your premises. We evaluate your building's lightning risk, the sensitivity of your equipment, and the potential consequences of surge damage to design the most effective strategy.
Our risk assessment considers factors such as building height, local activity, the presence of sensitive electronic equipment, and the critical nature of your operations. Questions like at what height does a building require lightning protection are addressed through this analysis, which determines the types and locations of devices needed to provide optimal coverage.
Our work complies fully with BS EN 62305-4, the British Standard for protection against lightning. For those asking what is BS EN 62305, this comprehensive standard specifies requirements for electrical and electronic systems within structures, ensuring your installation provides reliable coverage and meets all regulatory requirements.

From hospitals and schools to heritage-listed buildings — we’ve done it all.
Surge protection works most effectively when integrated with a complete lightning protection system. We coordinate your devices with external lightning protection, ensuring that lightning currents are safely channelled to earth while protecting all electrical and electronic systems within your building.
Our integrated approach ensures that your installation complements your lightning protection system, creating a comprehensive defence against all types of lightning-related threats. This coordination is essential for optimal coverage and compliance with current standards.
We design combined strategies that address both external lightning protection and internal surge coverage. This approach ensures that whether lightning strikes your building directly or nearby, your electrical equipment and sensitive electronic equipment remain protected.
You need surge protection for your home to prevent sudden electrical surges from damaging your appliances, wiring and electrical systems. It helps reduce the risk of fire and costly repairs.
Surge protection installation involves fitting devices to your electrical system that divert excess voltage safely during spikes. This protects equipment and wiring from being damaged.
Surge protectors are required under UK Wiring Regulations (BS 7671) for many domestic and commercial systems. They are strongly advised where power surges can cause serious harm or financial loss.
Surge protection installation costs vary based on the property size and setup but typically range from £150 to £500. A detailed quote should be provided after a site assessment.
A surge protection device lasts between 5 and 10 years depending on usage and surge exposure. Annual testing ensures it continues to work properly.
Surge protectors do need maintenance to stay effective, especially in high-risk areas. Regular inspections help detect wear and ensure full protection.
