Statutory Control and Installation Requirements

In general, the Regulations are non-statutory; however, they can be used as evidence to claim compliance with a statutory requirement. The statutory requirements that the BS 7671 support are listed in Appendix 2 of the Regulations, according to their application.

115.1

For installations in premises over which a licensing or other authority exercises a statutory control, the requirements of that authority shall be ascertained and complied with in the design and execution of the installation.

Chapter 12 – Objects and effects

This is a short chapter which is unlikely to prompt any questions in 2382-18. This chapter introduces the structure of the rest of the Regulations. It does contain the important note that if the designer deviates from any part of the Regulations, the resulting degree of safety is not less than that obtained by compliance with the Regulations.
