Mechanics rely on a variety of tools and equipment to keep vehicles running smoothly. From power tools and diagnostic machines to compressors, battery chargers, and workshop lighting, your workspace is full of electrical devices that are critical to your work. Faulty equipment can cause injuries, downtime, or damage to vehicles and tools.
PAT testing (Portable Appliance Testing) ensures that all your electrical equipment is safe, reliable, and ready to use, keeping both you and your workshop protected.
What Is PAT Testing?
PAT testing is the process of checking electrical appliances to make sure they are safe to use. It typically involves:
- Visual inspection – looking for damaged plugs, frayed cords, or signs of wear.
- Electrical testing – using specialist tools to detect hidden faults that could cause shocks, fires, or equipment failure.
Each item is labelled pass/fail, and a certificate is issued. PAT testing helps maintain a safe and compliant working environment.
Why PAT Testing Matters for Mechanics
Even minor faults can be hazardous in a workshop. PAT testing helps by:
- Protecting yourself and colleagues – reducing the risk of electric shocks or fires.
- Preventing downtime – avoiding interruptions caused by faulty tools or equipment.
- Maintaining professional standards – showing clients and staff that safety is a priority.
- Supporting insurance compliance – liability and workshop insurance often require PAT-tested equipment.
- Extending tool lifespan – early detection of faults prevents damage to expensive equipment.
What Equipment Should Mechanics Get PAT Tested?
Any electrical device used in your workshop should be included:
- Power tools such as drills, grinders, and impact wrenches
- Diagnostic machines and battery chargers
- Air compressors and workshop lighting
- Extension leads, power strips, and adapters
- Small appliances like heaters or fans used in the workshop
Even occasional-use or portable equipment should be tested to avoid hazards.
How Often Should PAT Testing Be Done?
Frequency depends on usage:
- Annually – for frequently used, portable equipment.
- Every 2 years – for stationary or low-use devices.
- After visible damage or repairs – always retest before use.
Many workshops schedule PAT testing annually or before peak work periods to ensure all equipment is safe and operational.
Is PAT Testing a Legal Requirement?
PAT testing itself is not explicitly required by law, but UK and European regulations mandate that all electrical equipment used at work must be safe. PAT testing is the recognised method to demonstrate compliance and is often requested by insurers, health and safety inspectors, or clients.
Final Thoughts
As a mechanic, your focus should be on vehicles, repairs, and diagnostics—not worrying about faulty equipment. PAT testing ensures that your tools and workshop equipment are safe, reliable, and professional, allowing you to work efficiently and confidently.
Because the only sparks in your workshop should come from engines—not electrical faults.
