How often should fixed wire testing be carried out?

What is the recommended frequency period between testing of the Fixed Wire aspect of your business within your workplace?

The reality is it can vary between 1 to 5 five years dependent upon your business type. So how often does it need to be for your particular business?

Fixed Wire Testing is also by some referred to as an Electrical Installation Condition Report.  It makes sure your electrical installations or circuits match to the current regulations for wiring. This makes sure your business is in compliance with work safety legislation.

How regularity of your testing is covered in the current version of ‘IET Wiring Regulations. This is currently BS7671:2018.  It is defined by:

  • Installation type
  • Frequency of use
  • The environment or external influence to which the electrical installation is subjected

For a lot of commercial business an Electrical Installation Condition Report which previously was called a ‘Periodic testing report’ will:

  • Only be required at frequency level of 5 years i.e. the lowest level.

However, for the higher risk type of environments the frequency level will require a more frequent testing period i.e. every 3 years.

Please be aware the periods stated above are the maximum period between testing intervals. Any deterioration of the electrical installation can indicate the requirement to make the interval between testing to be shorter.
