Lightning Protection Service

What is the need for Lightning Protection Service?

Lightning strikes hit the ground approximately 300,000 times each year. The lightning protection system is there to intercept, conduct and disperse a lightning strike safely to earth. Without a system a building’s structure, electronic systems and the people working around or within it are all at high risk. There are many ways in which lightning strikes can cause damage or injury. Lightning strikes (or even electrical discharges due to nearby lightning) can cause fires, explosions, chemical release or mechanical disruption within or around a building. This could lead to injuries or even loss of life.

Lightning Protection Requirements according to British Standard (BS EN 62305)

Section 5 of Electricity at Work Act 1989 states that all lightning conductors should be visually inspected and tested at regular fixed intervals, preferably not exceeding 12 months.

The inspection ensures that the lightning protection measures up to the relevant British standard (BS EN 62305) which will then reduce the risk of damage to a structure and the systems and people within the building.

Their purpose of the lightning protection is to carry the current safely to earth and ensure the continued functioning of equipment, the protection of the building or structure, and the safety of the people inside. A system which is not properly maintained might not be effective in carrying the current to the ground.

Are Lightning Conductor Inspections and Retestings necessary?

The lightning conductor retesting inspections includes an overall visual to ensure the system is in good working condition and the taking of all earth readings which are accessible. This included the main points below:-

  • Resistance to earth readings for each earth termination
  • Equi-potential bonds
  • Corrosion of earth electrodes
  • Conditions of connections
  • Deterioration and corrosion of air-termination elements, conductors and connections
  • Conductor fixings

Highwire Ltd’s engineers are full competent in undertaking the detailed inspection and testing all lightning protection systems. Our lightning protection engineers hold gold cards and provide an excellent service whilst on site.


Upon satisfactory inspection and testing, all equipment will be certified accordingly and any reports issued at no extra cost.  Many of our competitors charge an additional fee for the certification.

A full photographic report will be issued when a system fails, to enable our customer to see the works required. We will then have the works carried out at your earliest convenience, so that you are compliant to the regulations.

We always inspect and recertify every single accessible earthing position on site, whereas a lot of our competitors will test and inspect only 1 in 3 or 4 positions and give you an overall reading. This is less time consuming for the sub-contractor but is not an efficient reading for the client.
