How Often Should You Carry-Out Fixed Wire Testing in Your Home or Business?

A fixed wire test is an inspection of the condition of electric installations. It identifies any defects in the wiring or associated electrical equipment to ensure it is safe.

That’s why fixed wire testing is important – it saves lives.

For most homes and businesses, the interval between one fixed wire testing and the next is five years. However, it can be as low as one year for others. The interval period depends on the type of business you do.

Some people refer to fixed wire testing as an Electrical Installation Condition Report or EICR. This test is carried out to ensure your electrical installations or circuits are working in optimal condition.

It also ensures that your electrical system matches the current legislation for wiring and safety.

Your testing’s regularity is stipulated by the current version of IET Wiring Regulations, also known as BS-7671:2018.

The following three factors define the frequency of testing;

  • Installation type of the electrical system
  • Frequency of usage
  • External environment which may influence the electrical system

For the majority of homes and commercial businesses, an EICR certification will only be required once every five years. This provision is only applicable to those specific businesses with a minimal risky environment.

The frequency continues to increase as the risk-factor rises.

Please note that the periods stated in this article are the maximum possible period between testing intervals. You can decide your own schedule for greater efficiency and carry out the testing before you are legally obligated.

In fact, it shows a great initiative on your part if you do not wait for the absolute limit allowed by the regulations and take steps for increased efficiency beforehand.
