PAT Testing

PAT testing is the periodic testing of portable electrical appliances. It is required at workplaces including offices, factories and construction sites but is useful in domestic premises. Testing uses a special test device that detects invisible faults with insulation, wires and earthing.

PAT testing ensures your electrical appliances are safe and reduces the risk of electric shock and fire. PAT testing can also find electrical devices which are causing intermittent tripping of RCDs in consumer units. An electrical device with an intermittent fault can cause “nuisance” trips and can be difficult to find.

What are the employer’s obligations?

The business owner is responsible for the safety of employees using portable electrical equipment on-site and at home. Periodic inspection and testing come under legal requirements which you need to adhere to, which include:


Buildings, business continuity and employer liability insurance policies can be affected by electrical safety clauses. Insurance companies sometimes insist on annual PAT tests. Always check your policy.
