Portable Appliance Testing, more commonly known as PAT testing, is one of those jobs that can feel tedious and time-consuming — but it plays a vital role in keeping people safe, protecting property and ensuring legal compliance across workplaces and rental properties throughout the UK.
At Offset Facilities Management, we carry out professional PAT testing and provide full digital certification and reports, complete with photographic evidence, giving our clients clear, documented proof of compliance and peace of mind.
What is PAT Testing in Simple Terms?
PAT testing is the process of checking electrical appliances to make sure they are safe to use. It helps identify faults that could cause:
Electric shocks
Fires
Damage to equipment
Injury to occupants or staff
In everyday terms, it is about making sure plugs, leads and appliances are not dangerous before someone gets hurt.
While not every single item legally requires testing by law at set intervals, employers, landlords and business owners have a legal duty of care under the Health and Safety at Work Act and Electricity at Work Regulations to keep equipment safe. PAT testing is the most practical and recognised way of proving this duty is being met.
Yes, It’s Tedious – But Here’s Why It’s Necessary
PAT testing can involve dozens, sometimes hundreds of items in large buildings. It can feel repetitive, but the importance cannot be overstated.
Regular PAT testing helps to:
Prevent electrical fires
Reduce risk of injury or death
Identify wear and tear before it becomes hazardous
Ensure insurance validity
Demonstrate compliance during audits or inspections
Quite simply, it turns hidden risk into visible control.
How PAT Testing Works – Broken Down Simply
Each electrical item is tested based on its class. Here’s what that means.
Class 1 Appliances (Earthed Equipment)
These appliances have metal parts and rely on an earth connection for safety.
Examples:
Kettles
Fridges
Microwaves
PCs
Washing machines
Testing steps:
Visual inspection of plug, cable and appliance for damage
Earth continuity test (checks the earth connection is working)
Insulation resistance test (ensures electricity isn’t leaking)
Class 2 Appliances (Double Insulated)
These do not rely on an earth wire and have extra insulation built in.
Examples:
Phone chargers
Desk lamps
Handheld power tools
Hair dryers
Testing steps:
Visual inspection of casing, cable and plug
Insulation resistance test
Functional test where required
Class 3 Appliances (Low Voltage)
These operate at very low voltages and are typically powered by adapters.
Examples:
Some LED lights
IT equipment powered by transformers
Testing steps:
Visual inspection
Functional safety check
No live electrical testing usually required
The PAT Testing Process Step-by-Step
Visual inspection – checking for obvious damage or wear
Plug inspection – ensuring wiring is correct and secure
Electrical testing using calibrated PAT equipment
Pass or fail result recorded
Asset tagging with test date and next due date
Digital report generated for client records
Any items that fail are clearly marked and isolated to prevent use until repaired or replaced.
Why PAT Testing is Important for Landlords & Businesses
For landlords, managing agents and commercial property owners, PAT testing demonstrates that reasonable steps have been taken to protect tenants, employees and visitors.
It also:
Supports compliance with fire safety requirements
Reduces potential liability claims
Strengthens insurance compliance
Improves overall property safety standards
In shared environments such as offices, HMOs, schools and commercial units, this becomes even more critical.
