Is Electrical testing a Legal Requirement?

< Back

Regular testing of a building’s wiring structure and maintenance is mandatory by law under The Electricity at Work Regulations 1989 and IET Wiring Regulations BS 7671:2018. The frequency of testing required for compliance varies between environments, determined by a number of factors such as the use, operation and other external influences affecting the installation.

The IET Wiring Regs provide guidance on the maximum interval between fixed wire tests, based on the type of premises.
