In a busy garage or workshop, electrical tools and equipment are used every day. From power drills and chargers to inspection lamps and pressure washers, your kit works hard—and with heavy use comes wear and tear. To keep your team safe and your business compliant, PAT testing (Portable Appliance Testing) is essential.
In this blog, we’ll cover why PAT testing matters for mechanics, what needs testing in a workshop, and how often it should be done.
What Is PAT Testing?
PAT testing is the process of checking portable electrical appliances to ensure they’re safe. It involves:
- Visual inspection – looking for damage to plugs, cables, or casings.
- Electrical testing – using specialist equipment to check wiring and safety performance.
Each item is labelled with a pass or fail, and businesses usually get a certificate to keep for records and insurance purposes.
Why Mechanics Need PAT Testing
In a garage, tools and equipment are constantly plugged in, moved around, and exposed to oil, grease, and dust. Over time, that can make them unsafe. PAT testing helps by:
- Protecting staff and customers – reducing the risk of shocks, fires, or electrical accidents.
- Meeting legal duties – the Electricity at Work Regulations require safe equipment.
- Keeping insurers happy – many insurance policies expect PAT testing as proof of compliance.
- Preventing downtime – early detection of faults helps avoid tool failure during critical jobs.
What Workshop Equipment Needs PAT Testing?
If it plugs in, it should be checked. Common items in a mechanic’s workshop include:
- Power drills and electric wrenches
- Extension leads and cable reels
- Battery chargers and jump starters
- Inspection lamps and work lights
- Pressure washers and vacuums
- Computers, printers, and office gear
Don’t forget the office side of the business—kettles, microwaves, and heaters in the staff room should be included too.
How Often Should Mechanics Test Their Equipment?
The frequency depends on use, but for workshops, annual PAT testing is the industry standard. High-risk items, like handheld power tools, may need testing more often if heavily used.
A good rule of thumb:
- Yearly – portable power tools and workshop gear.
- Every 2 years – office equipment and low-use items.
- After repairs/damage – always retest before use.
Is PAT Testing a Legal Requirement for Garages?
There isn’t a law that says “you must do PAT testing,” but UK regulations (like the Electricity at Work Regulations 1989) require all electrical equipment in the workplace to be safe. PAT testing is the recognised way to prove you’re meeting that duty of care.
Final Thoughts
For mechanics, PAT testing isn’t just a box-ticking exercise—it’s about keeping your team safe, protecting your business, and avoiding costly downtime.
By booking regular PAT testing, you’ll have peace of mind that your tools and workshop are compliant, reliable, and ready for the job.
