Portable Appliance Testing (PAT) is the process by which everyday electronic appliances are inspected for safety. These tests are done ‘in-service’ and must be carried out at least every 2 years.
What exactly is PAT testing?
PAT testing isn’t actually just one test but is a group of different tests used to inspect electrical appliances. Either through formal visual inspection or a PAT testing machine – of which there are many different types – an electrician, or other competent person, will determine the safety of electrical appliances.
Once the appliance has been PAT tested and passed, it will be given a label to stick on it detailing that it has passed its PAT test, the date when the next inspection is due and the company who carried out the testing. These labels are not obligatory to display, but are helpful so you can easily see when an appliance is due for an inspection. If it fails, you will be given advice on how to rectify this.
Why do we need PAT testing?
Some people think that PAT testing is just another level of British bureaucracy. An unnecessary piece of red tape that’s there just to add to already over-the-top health and safety requirements.
This could not be further from the truth…
PAT testing is there to make sure that any electrical appliances that you and your employees come into contact with are safe to use. Without checking the safety of appliances on a regular basis, you may be putting your employees in danger of a 230 volt electric shock – which could potentially cause serious injury or even kill them.

PAT Health & Safety
The Health and Safety Executive say that 25% of all reportable electrical accidents are caused by electrical appliances. Under the Electricity at Work Regulations 1989, all electrical equipment that has the potential to cause injury must be maintained in safe condition.
Why PAT is Important
You may think that your appliances are working well and are causing no problems – but without a PAT test to ensure their safety, how can you be sure someone won’t pick them up and suffer an electric shop from an exposed wire or a malfunction of the appliance?
A fault can develop gradually on any appliance without anyone noticing, especially those used on a daily basis. As an employer, you are responsible for your staff’s wellbeing. The injury or death of one of your employees on your business premises would at best result in your business’ reputation being tarnished and at worst, legal action.
PAT testing should be a part of every business’ maintenance plan, from offices to factories and everything in between. Contact us for a PAT test quote today!
