You are legally required in the UK to operate a business or organisation in line with the regulations, requirements and guidance of Health and Safety. Where electrical safety is concerned we have to consider the:

Health and Safety at Work Act 1974

The Electricity at Work Regulations 1989

The Provision and Use of Work Equipment Regulations 1998

The Management of Health and Safety at Work Regulations 1999

Not complying with these regulations is very serious and can result in fines, even imprisonment. One of the easiest and most recognised methods to help you comply with these regulations is PAT testing. 

The law requires employers and the self employed to ensure that all electrical equipment that they provide for their business is safe and correctly maintained. As PAT (portable appliance testing) confirms safety it should be an important part of your health and safety regime.
