A risk assessment is a systematic process of identifying hazards in the workplace, evaluating the likelihood and severity of harm, and deciding on control measures to reduce the risk to an acceptable level. For electricians, this means looking at every aspect of a job — from the electrical hazards of working on live or potentially live equipment to the physical hazards of the work environment — and documenting how you will manage each risk.
The risk assessment is not a tick-box exercise. It is a legal requirement under the Management of Health and Safety at Work Regulations 1999 (Regulation 3) and the Health and Safety at Work etc. Act 1974 (Section 2). Every employer must carry out a suitable and sufficient assessment of the risks to the health and safety of employees and anyone else who may be affected by the work. Self-employed electricians have the same duty.
For electrical work specifically, the Electricity at Work Regulations 1989 impose additional duties. Regulation 3 requires that all systems are constructed and maintained to prevent danger. Regulation 4 requires that all work activities on or near electrical systems are carried out in a manner that prevents danger. The risk assessment is the mechanism by which you demonstrate compliance with these duties.
A good risk assessment protects you, your employees, your clients, and anyone else on site. It also protects your business — if an incident occurs and the HSE investigates, the first thing they will ask for is your risk assessment. If you do not have one, or if it is inadequate, you face enforcement action, improvement notices, prohibition notices, or prosecution.
