PAT Testing: What Businesses and Landlords Need to Know
Portable appliances are part of everyday life in almost every workplace and rental property. From kettles and computers to extension leads, power tools and kitchen equipment, we rely on electrical appliances every day.
But how do you know they’re safe to use?
Portable Appliance Testing (PAT) is one way of helping to identify electrical safety issues with appliances and equipment before they become a problem.
At Pentacle Electrical and Security Ltd, we carry out PAT testing for businesses, landlords and other property owners, helping them identify potentially unsafe equipment and maintain appropriate records.
What Is PAT Testing?
PAT testing is the inspection and, where appropriate, electrical testing of portable and movable electrical equipment.
It isn’t simply a case of putting a sticker on an appliance.
A competent person will consider the condition of the appliance and its cable, plug and connections, carry out appropriate tests where required, and determine whether the equipment is suitable for continued use.
Visual inspection is an important part of the process because not every defect will be identified through electrical testing alone.
Is PAT Testing a Legal Requirement?
This is an area where there’s a lot of confusion.
There isn’t a blanket legal requirement stating that every electrical appliance must receive a PAT test every 12 months.
Instead, businesses and landlords have responsibilities to ensure electrical equipment is maintained so that it remains safe.
The appropriate approach will depend on factors such as the type of equipment, how and where it is being used, and the level of risk involved.
That means a sensible inspection and testing regime should be risk-based, rather than simply testing everything because a sticker says it is due.
How Often Should PAT Testing Be Carried Out?
There isn’t one universal testing interval that applies to every appliance.
For example, equipment used heavily on a construction site is likely to experience very different conditions from a desk lamp in an office.
Factors that can influence the appropriate inspection frequency include:
• How frequently the equipment is used.
• The environment in which it is used.
• Whether it is moved regularly.
• The age and condition of the equipment.
• The consequences of an electrical failure.
• Previous inspection and testing results.
A competent person can help determine a suitable inspection and testing regime based on the circumstances.
What Happens During a PAT Test?
A typical PAT testing visit can involve a combination of visual inspection and electrical testing.
Equipment may be checked for:
• Damaged cables.
• Cracked or damaged plugs.
• Signs of overheating.
• Damaged casings.
• Loose connections.
• Incorrect fuses.
• Deterioration caused by use or the environment.
Where appropriate, electrical tests can then be carried out using specialist test equipment.
The results can be recorded so that the person responsible for the equipment has a clear record of what has been inspected and tested.
What Happens If an Appliance Fails?
Finding a failed appliance doesn’t necessarily mean it needs to go straight into the bin.
The reason for the failure should be considered.
Sometimes a relatively straightforward repair may be possible. In other cases, particularly where equipment is damaged or uneconomical to repair, replacement may be the sensible option.
The important thing is that equipment identified as unsafe shouldn’t simply be returned to service without the issue being addressed.
PAT Testing for Landlords and HMOs
For landlords, electrical appliance safety is particularly important where tenants are provided with electrical equipment.
In HMOs and other rental properties, appliances can be used by multiple occupants and may experience considerably more wear and tear than equipment in a private home.
Regular visual inspections and appropriate testing can therefore form an important part of a landlord’s overall approach to electrical safety.
PAT testing should, however, be considered alongside the safety of the fixed electrical installation itself. An EICR and PAT testing serve different purposes and should not be treated as the same thing.
PAT Testing for Businesses
Businesses may have dozens or even hundreds of electrical appliances in use across their premises.
Computers, monitors, kitchen appliances, chargers, extension leads and power tools can all potentially become damaged through everyday use.
A structured inspection and testing programme can help businesses identify problems, maintain records and demonstrate that electrical equipment is being appropriately managed.
It can also help prevent a damaged appliance from remaining in service simply because nobody noticed the problem.
Don’t Forget the Simple Visual Check
One of the easiest ways to improve electrical safety is also one of the simplest.
Look at the equipment.
Before using an appliance, check for obvious signs of damage. Look at the plug, cable and appliance itself.
If something looks damaged, smells of burning, is unusually hot or has started behaving differently, stop using it and have it checked by someone competent.
PAT testing isn’t a substitute for common sense—and common sense isn’t a substitute for appropriate inspection and testing.
They work together.

PAT testing in the real world

Portable appliance testing involves more than simply attaching a tester and waiting for a result. Equipment needs to be assessed appropriately, including visual inspection, before deciding what testing is required.
By checking appliances systematically and recording the results, businesses and property owners can build a clearer picture of the condition of the equipment they’re responsible for.
And sometimes, it’s the visual inspection that identifies the problem before any electrical test is even carried out.

💡 Pentacle Pro Tip
Don’t rely on the date on a PAT sticker alone.
A piece of equipment can become damaged the day after it was tested.
Encourage staff, tenants and anyone using electrical equipment to report damaged plugs, cables or appliances immediately rather than continuing to use them until the next scheduled inspection.
