Lightning Protection For Churches

Front cover for Lightning Protection For Churches: A guide to design and installation

A guide to design and installation

Whether or not a church has lightning protection, those concerned with its upkeep will wish to consider how to protect it against the effects of a lightning strike and whether any existing system is adequate. To enable them to make informed decision either to install protection where none exists, or to upgrade existing systems and to what level, this guide seeks to:

  • indicate in practical terms the likelihood of a lightning strike
  • set out the possible consequences of a strike
  • suggest a system of protection against the risk of strike damage
  • offer some advice on good installation and maintenance practice

This guide is based on statistical evidence for lightning strikes to churches and the consequences, obtained from Ecclesiastical Insurance Group records and other sources. The data are mostly concerned with Anglican churches although the principles of protection should apply to all generally similar buildings. It is hoped that the guide will be of assistance to architects, surveyors, engineers and other concerned with the design, installation and maintenance of lightning protection systems. It may also be of help to interested lay people by informing them of the issues involved.
