Section 3(2) of the Health and Safety at Work etc. Act 1974 (“the 1974 Act”) was amended by the Deregulation Act 2015 (c. 20) to limit the scope of the general duty under that section. Only those self-employed persons who conduct undertakings of a prescribed description will have an obligation to conduct their undertaking in such a way as to ensure that, so far as is reasonably practicable, they themselves and other persons who may be affected thereby are not exposed to risks to their health and safety.
