Lightning Protection Services

We have built a fine reputation for the quality design and installation of lightning protection systems (LPS).

For many years we have worked closely with consultants and architects, designing lightning protection systems for various projects. We are prepared to design and quote for any project requiring lightning protection from a private dwelling, major hospital developments and large commercial buildings. Utilising our well established Steeplejack expertise we are highly competent in the installation of lightning protection on any structure, especially those that require specialist access. With our years of experience, we can safely install a lightning protection system even on the tallest structures where lightning protection is needed the most eg. tall chimneys, church spires and large cooling towers. If you have any buildings or structures that you feel need lightning protection please do not hesitate to contact us for advice.

We pride ourselves on years of experience and offer the following lightning protection services.

1 Design of systems
2 Preparations of drawings
3 Site surveys
4 Free estimates
5 Full installations capabilities
6 All codes of practice followed for the inspection and testing of Lightning Protection Systems.

We offer a service that will assist you understanding the technical aspects of lightning, so you can learn about its characteristics and any possible risks to your property.

Lightning Protection

A lightning strike can pass over 200,000 Amps depending on the severity and strength of the storm. In Britain a majority of strikes are around 2,000 to 20,000 amp, however this varies over the United Kingdom, Ireland, Wales, Scotland and the Channel Islands. Scotland experiences less thunderstorms than the South of England.

The function of a lightning protection system is to offer a safe low resistance path for the enormous currents caused by a lightning strike to travel to ground along. With a lightning protection system the immense energy is offered a safe alternative path away from the materials of the structure or building being protected. This current is then safely discharged under ground, preventing damage to property and equipment that is normally associated with the dispersal of radial energy from a lightning strike.

An Example of Lightning Protection

Most churches are fitted with a single conductor being BSCP 326 (BSCP – Building Standards Codes of Practice). This provides a zone of increased safety referred to as a cone of protection. It exists from the highest point of the conductor to the ground at an angle of 45 degrees in all directions. Producing a coned area with the point of the conductor being the top peak of the cone, and the ground the base of the cone. For a spire that is 40 metres in height, the cone of protection is roughly 40 metres out from the centre of base of the spire in all directions up to the top of the spire at a 45 degree angle.

Where a church is fitted with a Faraday Cage as part of the lightning protection system and complying to BSCP 6651, it will have a system fitted to all parts of the structure and bonded to any extrinsic metals to avoid flashovers, these systems have down conductors spaced at approx 20 metres or shorter, with roof and down tapes all linked to form the faraday cage.

The latest standard BSEN 62305 was introduced in August 2008. However lightning protection systems compliant to British Standards BS 326 & BS 6651 can still be maintained, tested, certificated the same as previously.

Installing A Standards Compliant Lightning Protection System (LPS)

All our recommendations for any installation are designed in accordance with the relevant British Standard. It is very important that lightning protection systems are designed and installed correctly. All our operatives are DEHN trained. DEHN are the fore-bearers of the BS EN 62305 standard and the leading providers of BS EN 62305 compliant lightning protection and safety products in Europe.
All BS & EN Standards recommends that lightning protection systems should be inspected and tested at fixed intervals, preferably not exceeding a 12 month period.
Do not let a lightning strike affect you, contact us today to find out how we can assist you with the installation and maintenance of a lightning protection system. Providing you with peace of mind, a safer environment and better protection during the next lightning storm.

Lightning Safety

Lightning is to be respected. If you find yourself in the presence of a lightning storm follow the 30/30 rule and seek cover in a building, preferably one fitted with a lightning protection system, or a car enclosed with a metal body work. Avoid touching or standing near anything that may conduct electricity from a lightning strike. eg. like heating radiators, taps. Do not stand under any tall or isolated trees. See our safety page for more information and tips.
