PAT Testing Guide: What It Is, Frequency and Legal Requirements

PAT testing – short for portable appliance testing – is the inspection and testing of electrical equipment to make sure it is safe to use. While the name is well known, many landlords and business owners are unsure what it covers or how often it is needed. This guide explains PAT testing in plain English and sets out your legal duties.

For the official guidance, see HSE portable appliance testing FAQs.

What is PAT testing?

Portable appliance testing involves a trained electrician inspecting electrical appliances for damage and carrying out electrical tests to confirm the equipment is safe. Each appliance is given a pass or fail result and recorded on a PAT testing certificate.

Is PAT testing a legal requirement?

There is no single law that says PAT testing must be done, but the Electricity at Work Regulations 1989 require you to maintain electrical equipment in a safe condition. PAT testing is the recognised way to prove you have done this, and it forms part of your wider duty under the Health and Safety at Work Act.

  • Formal visual inspection of cables, plugs and casings
  • Earth continuity test
  • Insulation resistance test
  • Polarity check
  • Clear pass or fail label on every item

A qualified and competent person carries out the work using calibrated testing equipment. The results are recorded so you can demonstrate your equipment has been maintained safely.

How often should PAT testing be done?

The frequency depends on the environment and the type of equipment. Offices and shops commonly use a 12-month cycle, while some low-risk items can be extended to two or four years. Your electrician will recommend a sensible schedule for your business after the first test.

Who needs PAT testing?

What does a PAT test cost?

Landlords providing furnished accommodation, employers with portable equipment, and anyone running a public or commercial space should arrange regular testing. If an appliance causes an incident and you cannot show it was tested and maintained, you could face serious penalties.

What happens during a PAT test?

Testing is priced per item, with a minimum charge for a call-out. The exact cost depends on how many appliances you have and how long the visit takes. You can view our PAT testing service for a straightforward price and clear report.

PAT testing for landlords

The electrician inspects each appliance visually, then plugs it into a testing device that checks the electrical safety of the wiring inside. Every item is labelled with the result and you receive a certificate summarising the findings.
