PAT Testing (Portable Appliance Testing) is one of the most effective ways to ensure your electrical equipment is safe, compliant, and reliable. But in the hustle of day-to-day business, it’s easy to let testing dates slip through the cracks.
At MES Pat Testing, we often work with businesses who had no idea they were overdue—until something went wrong. So, how can you tell if it’s time to book a test?
Here are 5 key signs your business is overdue for PAT Testing.
- Your PAT Test Labels Are Outdated or Missing
One of the simplest signs is also the most obvious. If you can’t find:
A pass/fail sticker on appliances
A date of last test
A clear “next test due” label
…it’s likely that your equipment hasn’t been checked in a while—or perhaps ever.
Every appliance tested by MES Pat Testing receives a visible, dated label so you always know where you stand.
- Equipment Is Showing Wear or Damage
Frayed cables, cracked plugs, scorch marks, or loose connections are all signs of physical damage—and a clear indication that testing is overdue.
These faults often go unnoticed until someone gets a shock or a fire starts. PAT Testing identifies these risks early, keeping your staff, customers, and property safe.
- You Can’t Remember the Last Time You Had PAT Testing
If you don’t have a record of your last PAT Test—or it was over a year ago—you’re likely out of date.
Most workplaces should carry out PAT Testing:
Annually for general office and shop equipment
Every 3–6 months for high-risk environments like construction
At each tenancy change for landlords
MES Pat Testing provides detailed reports and reminders, so you never fall behind again.
- You’ve Added New Staff or Equipment
Hiring new team members? Expanded your office? Bought new appliances or IT equipment?
These changes mean more devices in use—and more potential risks. Whenever you make operational changes, it’s a good time to review your PAT Testing status and retest or test new items.
- Your Insurance or H&S Audit Is Coming Up
Many insurers require proof of equipment maintenance—and that includes PAT Testing. The same goes for health and safety inspections and landlord responsibilities.
Being unable to provide up-to-date PAT Testing certificates could put your business at risk of invalid claims, failed audits, or legal issues.
