Prevention is better than the cure
Based in West Sussex, we specialise in the design, installation, testing, and maintenance of lightning protection systems. Our services extend across Sussex, Surrey, Hampshire, the Isle of Wight, and London. We offer comprehensive lightning protection solutions tailored to your needs.
In the UK, the protection against lightning strikes is regulated by British Standard BS EN 62305. This standard provides guidelines for safeguarding structures and people from lightning. It covers various types of structures like buildings, bridges, and towers.
When designing and installing a lightning protection system in the UK, a risk assessment specific to the structure is conducted. Factors such as the structure’s location, height, likelihood of lightning strikes, and potential consequences to life, are considered.
A complete lightning protection system includes lightning rods, earthing systems, and surge protectors. Lightning rods attract lightning strikes and safely direct the electrical charge to the ground. Earthing systems provide a path for the charge to dissipate harmlessly. Surge protectors help limit the voltage and current caused by lightning strikes.
Regular testing and maintenance are important to ensure the effectiveness of lightning protection systems. The standard recommends inspections, testing of grounding resistance, and checking the integrity of lightning rods and surge protectors.
By following the guidelines in BS EN 62305, buildings in the UK can reduce the risk of damage and injuries caused by lightning strikes, making lightning protection an important aspect of building safety.
