PAT Testing FAQs

  • What is PAT testing?

    PAT testing (Portable Appliance Testing) is the inspection and testing of electrical appliances to ensure they are safe to use. It includes both visual inspections and electrical testing of portable equipment such as kettles, computers, extension leads, monitors, and power tools.

  • Is PAT testing a legal requirement?

    PAT testing itself is not specifically required by law, but UK businesses have a legal duty under the Electricity at Work Regulations 1989 to ensure electrical equipment is maintained in a safe condition. PAT testing is one of the most effective ways to demonstrate compliance.

  • How often should PAT testing be carried out?

    The frequency of PAT testing depends on the type of equipment and the working environment. Offices may require less frequent testing than construction sites or industrial environments. We can advise on suitable testing intervals for your business.

  • What appliances need PAT testing?

    Any portable electrical appliance connected via a plug may require PAT testing. This includes computers, monitors, kettles, extension leads, printers, microwaves, chargers, power tools, and cleaning equipment.

  • Will PAT testing disrupt our business operations?

    We aim to minimise disruption wherever possible. Our engineers can work around your operational requirements, including early morning, evening, or weekend appointments where needed.

  • Do you provide PAT testing certificates?

    Yes. Following completion of testing, we provide digital reports and certification detailing all tested appliances, pass/fail results, and any remedial recommendations.

  • Which areas do you cover?

    CWC provides PAT testing services across London and surrounding counties including Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey, and Sussex.
