Our Guide to Electrical Fixed Wire Testing


You may have heard about Fixed Wire Testing by its different names:

- Periodic Electrical Inspection

- Electrical Tests

- Electrical Installation Condition Reports (EICR)

- Landlord Safety Certificates

You may have heard about it, you may know you need it, or didnt know you needed it or would like to learn more about what Fixed Wire Testing involves before you set the wheels in motion.

On a basic level, Fixed Wire Testing involves a periodic inspection and test of an electrical system.

It encompasses all types of electrical installations within; a commercial, domestic or industrial system.

And is essentially an MOT for your electrical system.

What is Fixed Wire Testing and what does it involve?

Periodic test and inspection requires a series of visual inspections and electronic tests to be performed to establish the safety and suitability of your electrical system.

If performed correctly, you can expect that each electrical circuit within your workplace will have to be de-energised for a period of 15 minutes whilst the Engineer injects test signals into the cables and protective devices to ensure their integrity and carries out a thorough visual inspection of the Installation.

This type of work will require the main supply to be isolated and with careful planning can be done with little disruption to your business.

Alternatively, this work can be carried out whilst your workplace is empty, such as nights, weekends or holiday periods.

How Long Will it Take?

Small businesses can expect the test to last an hour or two, for medium businesses it can take 3-5 hours and for larger businesses the test can take 1-2 days.

There are several factors which will affect how long a test will take. An initial survey will provide an accurate test time and further details.

Who needs Fixed Wire Testing and why?

To put it simply, all premises require Fixed Wire Testing. They will not only require Fixed Wire Testing but also other Electrical Testing.

Any buildings or areas visited by the public are required to be safe, which includes the electrical installations at such premises & locations.

Electrical systems deteriorate over time and suffer wear and tear throughout their usage.

The Law?

The law requires that each installation must comply with the Health and Safety at Works Act 1974 and the Electricity at Work Regulations 1989.

These regulations expand upon how electrical installations must be maintained to a satisfactory condition and the most effective way to ensure this is through periodic Fixed Wire Testing.

How often do you need an EICR?

For a specific installation interval please refer to our news post detailing this - Fixed Wire Testing - Frequency Guide.

The recommended intervals between testing and retesting dates varies depending on the type of installation.

The general misconception or common belief is that domestic properties are tested every 10 years, commercial properties every 5 years.

However, we say misconception because the guides say these are the maximum intervals in between testing dates, and this seems to be the dates expressed to most unknown people. Although when looked at from a practical view instllations should be tested perhaps not fully but partially every 6-12 months. For this to be appropriate, a clear record of regular testing is required, and more so a detail of which points on what circuits have been tested. This would then allow for regular annual partial testing.

You must consider the safety of all those who will enter a building, use electricity, or enter the area you are responsible for, within a caravan park or amusement park for example.

The Health and Safety at Work Act 1974 states that it is the responsibility of the duty holder/Landlord or in a business the most senior person or individual responsible for Health and safety.

Regular Fixed Wire Testing will remove the burden and stress this can casue & puts your mind at ease; that your electrical system is fit for continued use.
