Only competent people with technical knowledge or experience should carry out electrical work. The National Inspection Council for Electrical Installations Contracting (NICEIC) enrols electrical contractors whose work is of an approved standard, and surveys work to ensure it complies with the Institution of Electrical Engineers Regulations. These regulations do not have statutory force but indicate good practice. Safety reps should ensure that if outside specialists are required, NICEIC-enrolled contractors are used.
