Health and safety regulations require that electrical appliances should have a current PAT test certificate ensuring they are safe to prevent harm to workers.

Legal Obligations

British law (the Electricity at Work Regulations 1989 ) requires that all electrical systems (including electrical appliances) are maintained (so far as is reasonably practicable) to prevent danger. A competent person must inspect the installation regularly in any public building or a place that people work; private houses do not need this test. Guidance from the Institution of Engineering and Technology (IET, published under the IEE brand) and the Health and Safety Executive (HSE) suggest initial intervals for combined inspection and testing that range from three months (for construction equipment) to one year for inspection and, in many cases, longer periods for testing (certain types of appliance in schools, hotels, offices and shops).
