Fixed Wire Testing (EICR) & Portable Appliance Testing (PAT Testing) - combining electrical testing

Today we’ll be looking at Fixed Wire Testing (EICR) & Portable Appliance Testing (PAT Testing) and why you should be combining the two as key elements of your electrical safety and compliance.

Which one is more important?

Simply put, they are both important as both services cover different aspects that will ultimately help towards ensuring the overall electrical safety and compliance of your workplace.

Fixed Wire Testing is “the MOT of your electrical installations” - making sure that all relevant installations are safe and fit for use. Portable Appliance Testing is the best method for ensuring that all portable electrical items within the premises that staff and visitors use, are again, fit for purpose and safe to use.

As mentioned in the title, we urge all of our clients to ensure that they have both forms of electrical testing carried out for good practise and to ensure complete electrical safety and compliance in their workplace.
