Plugging it in? Make sure you've had a PAT test.

And no, that's not something which happens after you've set a walk-through metal detector off. Portable Appliance Testing (also known as 'PAT Testing') involves testing unfixed electrical equipment to make sure it's safe and fit for purpose.

All employers (even if you’re self-employed) are legally required to maintain (and prove they maintain) their electrical equipment. Continue down the page to learn more about PAT testing or if you’re ready to get sparks flying (not literally), hit the orange button below to submit your enquiry.

3 Reasons You Need To Have PAT Testing

1. Keeps You Above bOARD

It's a legal requirement to maintain (and prove you've maintained) your commercial building's electrical equipment. PAT Testing is how you achieve this.

2. Satisfies Your Insurers

Your insurance will usually require you have PAT Testing carried out. If you don’t maintain your electrical appliances properly your insurance provider may not cover your business.

3. Protects your people

Whilst this is essential from both a statutory and insurance perspective, keeping your people safe is also a pretty good reason to do it! This helps avoid electrical-related injuries.

What is Portable Appliance Testing?

Portable Appliance Testing (or ‘PAT Testing’ as it’s more commonly known) is a hugely important part of your commercial premises’ health and safety requirements. 

As an employer, you are responsible for ensuring electrical equipment is maintained to prevent accidents in the workplace. 

Damage, wear-and-tear and faults can occur, which is why it’s important to carry out your Portable Appliance Testing. It’s also incredibly important that this is carried out by a competent specialist (i.e. us!) who can readily identify and fix any electrical problems you might have.

PAT Testing is not to be confused with Fixed Wire Testing, which tests your electrical installation – also part of your electrical maintenance.

Plugs with a green sticker on to indicate testing has been done


The law states you’ve got to maintain your commercial building’s electrical equipment, primarily to keep your people safe. (This also applies to landlords and those who are self-employed.) The way you do this is through PAT Testing, so whilst PAT Testing isn’t directly a legal requirement, the function it does for you (i.e. maintaining your electrical equipment is).

Here are the laws which apply to maintaining your electrical equipment:

Health & Safety at Work Act 1974

This law outlines the responsibilities and duties of both employers and their employees “to ensure the health, safety and welfare of all persons at work” to help protect “against risks to health or safety”

Electricity at Work Regulations 1989

The aim of this is to help prevent death or injury from electrical causes whilst at work. It specifies “all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger”.

Provision & Use of Work Equipment Regulations 1998

These regulations talk about ensuring workplace equipment is properly inspected and safe for use, and does not subsequently deteriorate or present a health and safety risk.

Management of Health & Safety at Work Regulations 1999

This talks about risks and how employers ought to assess and manage posed safety risks, whilst employees should work in line with their employer’s protocols and training.

What Happens During Fixed Wire Testing?

Your PAT Testing visit will entail a visual inspection of all aspects of each appliance which is plugged into your mains within your premises. This includes the plug, the lead and the appliance itself, where your technician will be looking for signs of damage and overheating.

Class 1 appliances (things like kettles, fridges and general IT equipment) require a little extra care with an Earth Continuity test (because they rely on earth for protection) and an Insulation Test.

Your appliances will usually have a sticker on the back (as seen on the picture of the plug further up the page) which tells you when it was last tested. Once you’ve had your inspection, you’ll receive a report from us which is your evidence of having maintained your electrical equipment. This will also include any remedial works which you’ll need to consider if there have been problems identified during the inspection. 

How often you ought to have PAT Testing depends on the premises and the equipment you have. For example, construction sites using 110V equipment should be tested as frequently as every 3 months! The norm for most premises is to have Portable Appliance Testing every 12 months.
