A guide to Fixed Wire Testing

Fixed Wire Testing can prevent avoidable problems with your wiring, reduce any electrical risk and ensure your business is safe and fully compliant with relevant Health & Safety regulations. Once you’ve had all your Fixed Wire Testing inspected, you’ll then need an Electrical Inspection Condition Report (EICR) for your records – your insurance provider may want to see this too.

What is Fixed Wire Testing?

Fixed Wire Testing, also known as Periodic Testing or Inspection and Fixed Electrical Testing, is the process of checking the safety of electrical systems or installations in a building, to make sure they are safe for you, your staff, your customers and your visitors.

What do the observation codes mean in the Fixed Wire Test report?

Observation codes are items you will see on your EICR Fixed Wire Testing report, and they determine the actions that should be taken going forward. Here’s a brief overview of what each means:

  • C1 – ‘Immediate action’ is required due to a dangerous fault
  • C2 – Fault could be ‘potentially dangerous’ if left in its current state
  • C3 – ‘Improvement recommended’
  • F1 – ‘Further investigation required without delay’

How we minimise operational disruption

To reduce disruption to your employees and customers, where possible, we’d recommend Fixed Wire Testing is completed outside of your business’ normal operating hours.

I’m in a serviced office – is it my responsibility?
