In the UK, PAT testing itself is not a strict legal requirement. However, several pieces of legislation, such as The Electricity at Work Regulations 1989, require employers to ensure that electrical equipment is maintained in good working order and safe condition. While PAT testing is not mandated by law, it is a standardized method to comply with these regulations and demonstrate that electrical appliances are safe to use, thus helping to meet legal obligations.

The Electricity at Work Regulations 1989 are UK regulations that impose duties on employers, employees, and self-employed individuals to conduct electrical work safely and minimize foreseeable risks. These regulations expand upon the Health and Safety at Work Act 1974 and are designed to prevent the risk of death or personal injury from electricity in work activities. The most common method of compliance with these regulations is through PAT testing, although this is not the only method. The regulations require that electrical systems be constructed and maintained in a way that prevents danger, ensuring electrical safety compliance across various work environments.

Non-compliance with The Electricity at Work Regulations 1989 can result in significant legal consequences. Penalties can include fines and in cases of serious breaches that lead to severe injuries or fatalities, imprisonment. Additionally, non-compliance can damage a company’s reputation and result in financial losses due to legal proceedings, compensation claims, and business disruptions. Since February 2016, stiffer penalties have been introduced, emphasizing fines for putting employees at risk rather than just for accidents. Imprisonment has become more likely for directors, managers, and employees, and fines can reach up to £10M for large companies with a high level of culpability.
