a guide to fixed wire testing intervals

Fixed wire testing intervals are a key consideration for any business owner or facilities manager that wants to keep their site safe, efficient and compliant. In this post, we’ll take a look at how fixed wires are tested and how to determine the right intervals between tests.

Fixed wire testing: the basics

Before discussing the right intervals for fixed wire testing, it’s worth clarifying what exactly the tests are and why they’re so important. Fixed wire testing is covered by an Electrical Installation Condition Report (EICR), which comprises a thorough visual and physical inspection of your electrical system, including:

  • Defective work
  • Unsafe wiring
  • Shock risks
  • Fire hazards
  • Overloaded circuits

In short, fixed wire tests make sure your electrical installation is safe and efficient in line with BS 7671 standards. They should be carried out by someone who is qualified and competent. But it’s also important that they’re carried out periodically with the right fixed wire testing intervals.

Quite simply, that’s because of safety and compliance. Fixed wire testing is not a one-off task. As your electrical system is used, there’s a chance of components deteriorating and new risks emerging and developing.

Setting the right fixed wire testing intervals

When it comes to fixed wire testing intervals, the advice you’ll find online is quite limited. It’s well documented that landlords are now required to have an EICR completed at least every five years, which is often seen as a rule of thumb for commercial sites too.

In truth, fixed wire testing intervals should be determined on a case-by-case basis, with a maximum fixed wire testing interval included on your EICR report. Generally, they are required every one to five years, depending on a number of factors:

  • The type of electrical installation
  • How frequently it’s used
  • The environment within which it’s installed

Electrical installations that require shorter fixed wire testing intervals are usually those exposed to moisture, dust or especially high or low temperatures, including industrial units and leisure centres. However, places which are open to the public also carry a higher risk – such as fuel stations, cinemas and hospitals – calling for more frequent testing.

Check your EICR certificate

The good news is, there’s no need for guesswork when it comes to fixed wire testing intervals. As part of your EICR report, a qualified electrician will specify the maximum amount of time you should wait before your next inspection.

They will base their recommendation on the factors discussed above along with the condition of your electrical system. Your EICR report will also outline any issues identified with your installation, so you can make sure it is safe, compliant and running smoothly in the meantime.
