What is PAT testing?
PAT testing is a combination of visual inspection and (where appropriate) electrical testing of portable appliances and their leads — such as chargers, extension leads, and plug‑in equipment — to confirm they’re safe to use.
Most faults are found during the visual check, including:
- Damaged plugs
- Crushed or twisted cables
- Loose connections
- Exposed wiring
Is PAT testing a legal requirement?
UK law doesn’t state that you must PAT test every appliance once a year.
What the law does require is that electrical equipment is maintained in a safe condition.
PAT testing is one of the most practical and recognised ways to demonstrate that you’re managing electrical risk properly — especially in commercial environments.
Where is PAT testing used?
PAT testing is relevant in almost any workplace that uses plug‑in equipment, including:
Restaurants, cafés, takeaways
Kitchens involve heavy use, heat, moisture, and lots of portable appliances.
Offices

Why businesses in the South East do PAT testing
- Reduces the risk of electric shock and electrical fires
- Helps prevent downtime caused by faulty equipment
- Supports insurer, landlord, and audit requirements
- Provides clear records for compliance
- Identifies common issues early (damaged leads, incorrect fuses, unsafe extensions, worn plugs)
How often should PAT testing be done?
There’s no one‑size‑fits‑all rule. The best approach is a risk‑based schedule:
- High‑risk environments and frequently moved equipment should be tested more often
- Low‑risk, rarely moved office items may require less frequent checks
A professional PAT testing provider can help determine the right interval for your workplace.
