Electrical Installation Condition Report (EICR)

Five yearly fixed-wire testing is a legal procedure for organisations to ensure that all electrical equipment is safe for employee use.

The process of completing periodic testing usually means all electrical testing is done on a site every five years, testing all electrical installations for efficiency and flagging up any dangers that should be rectified. Instead of this, many firms now also opt to complete fixed wire testing in instances of 20% over the five yearly period, bringing in contractors to assess the building systematically over the next half-decade.

This new approach to fixed wire testing comes as a result of recent amendments to the IEE's wiring regulations, which states that electrical installations should not be left for five years as was previously the case.  Instead the procedure generally involves completing an annual visual check of electrical installations for damage that may have happened over the year, while the aforementioned 20% physical check is also adopted by many organisations as well.

In addition to the regulations set by the IET, it is also important to consider the type of environment that requires the testing. Certain public areas that raise a massive hazard if electrical appliances aren’t working correctly such as swimming pools must be tested much more frequently than other areas, so it is always worth researching which environment needs the testing and how soon it should be completed.

It’s also worth noting that the qualified professional carrying out the tests can do the following:

  • Flag up any dangerous installations for repairs

  • Decrease/increase the amount of time before the next inspection based on findings


Any testing done on site must be done by a qualified professional, but the frequency and amount of testing completed is ultimately up to the organisation carrying out the testing.
