PAT Testing: Who Needs It?
What Is PAT Testing?
While “PAT testing” is still widely used, the correct term (according to the IET Code of Practice, 5th Edition) is “in-service inspection and testing of electrical equipment.” It’s about keeping people safe by making sure electrical appliances used in the workplace are well-maintained and not hazardous.
Is PAT Testing a Legal Requirement?
Not exactly. There’s no law that says “you must PAT test.” But there is a legal duty under the Electricity at Work Regulations 1989 to ensure that all electrical equipment is maintained in a safe condition. PAT testing is the most recognised way to show that you’re meeting this duty — especially if something goes wrong.
Who’s Responsible?
The person legally responsible is often called the Duty Holder. This might be a business owner, facilities or maintenance manager, landlord, or someone managing safety and compliance. Their responsibilities include:
- Carrying out risk assessments to decide what needs testing and how often.
- Making sure testing is done by a competent person.
- Keeping records of tests and repairs.
- Taking action on equipment that fails or is reported as faulty.
Managing all of this with paper or spreadsheets can quickly become a burden. If you're wondering how software can simplify testing and record-keeping, have a look at our blog on the benefits of PAT testing software.
What Needs to Be Tested?
A common mistake is thinking only plug-in devices need testing. In reality, any electrical equipment used in the workplace or a publicly accessible environment should be included, such as:
- Office equipment – monitors, printers, laptops
- Kitchen appliances – kettles, toasters, microwaves
- Power tools – drills, saws, vacuum cleaners
- Extension leads and power strips
- Fixed appliances – like wall-mounted heaters or air conditioning units
- Personal items – anything employees bring into work (e.g. phone chargers or Christmas lights)
Where PAT Testing Applies
PAT testing isn’t just for offices. It applies in environments like:
- Construction sites – heavy tool use and harsh conditions
- Retail and hospitality – public access raises the risk
- Schools and colleges – shared use by students and staff
- Charity shops – testing donated appliances before resale
- Rental properties – landlords are responsible for provided appliances
- Hire companies – equipment must be safe before every rental
Why PAT Testing Still Matters
Even though it’s not legally mandated, PAT testing gives you documented proof that you’ve taken reasonable steps to keep people safe. It’s practical, defensible, and often expected by insurers and clients.
Good record-keeping is a big part of that. If you’re unsure what to log or how to stay organised, check out our article on how to keep PAT testing records.
Not sure how often you should test? It depends on the type of equipment, how often it’s used, and who uses it. We explain this in more detail in our guide to PAT testing frequency(#).
And if you're wondering how digital tools can help streamline this process, our article on the benefits of PAT testing software is a good place to start.
Final Thoughts
If you're responsible for workplace safety, PAT testing is likely part of your role — even if you didn’t realise it. The good news? It doesn’t have to be complex or time-consuming.
Start by understanding your responsibilities, testing the right equipment, and keeping good records.
What about remote workers?
If your team works remotely, you may still be responsible for equipment they use at home — especially if it's provided by the business. Risk assessments should cover remote setups, and you might consider including their kit in your testing schedule.
