Keeping electrical safety in check

Why PAT testing matters

17th September 2026

As a business owner it’s imperative to take electrical safety seriously because faulty appliances can present a potentially significant fire risk in commercial premises.

From computers, printers and monitors to kettles, microwaves, portable heaters and chargers, modern workplaces can contain a host of electrical appliances. And when equipment becomes damaged, is poorly maintained or develops an electrical fault, it can increase the risk of overheating, electric shock and even fire.

Warning signs can include frayed cables, cracked plugs, exposed wiring, scorch marks and appliances that become unusually hot during use. Overloaded extension leads and the continued use of damaged equipment can further increase the risk.

Regular Portable Appliance Testing (PAT), alongside routine visual inspections and effective maintenance procedures, can help identify potentially unsafe electrical equipment before it causes a serious incident.

PAT testing typically involves inspecting an appliance and, where appropriate, carrying out electrical tests to determine whether it’s safe to continue using the item. Equipment that fails can then be repaired or removed from service, reducing the likelihood of a fault causing injury or developing into a fire.

While UK law does not generally prescribe fixed PAT testing intervals for every appliance, employers have a responsibility to maintain electrical equipment where necessary to prevent danger. Our recommendation is to schedule annual PAT testing to mitigate risk.

It’s also prudent to encourage staff members to take simple actions to keep everyone safe, including:

  • reporting damaged equipment without delay
  • avoiding overloaded sockets and extension leads
  • ensuring all appliances are used according to the manufacturer’s instructions

Ultimately, the consequences of an electrical fire can extend far beyond damage to the building itself. Injuries, destroyed equipment, lost data and prolonged business interruption can all carry substantial costs too. A proactive programme of inspection, maintenance and appropriate PAT testing can therefore provide an important line of defence against preventable workplace fires.
