Lightning protection to commercial structures is covered by BS EN 62305:2011 which sets out the required performance of installed systems, and is far more comprehensive than BS6651 which it replaces. It is broken down into the following sections:

BS EN 62305-1 General principles – this provides the basic characteristics of an effective lightning protection system in accordance with the rest of the standards.

BS EN 62305-2 Risk management – details the wider considerations of lightning strikes such as danger to life, possible data loss, and cultural impacts if heritage buildings are damaged. Secondary economic implications of loss of services in the wake of lightning strikes are also analysed.

BS EN 62305-3 Physical damage to structures and life hazard – describes the basic categories of protection from lightning according to risk, and provides detailed guidance for an engineer designing a lightning protection system.

BS EN 62305-4 Electrical and electronic systems within structures – provides updated information and guidance for the protection of the sensitive electronic equipment typical in modern buildings, including servers and wired networks. A zoning system is recommended to help protect such equipment from the primary and secondary effects of lightning strikes.
