The Electricity at Work Regulations 1989 mean that if your building or premises is used for commercial, industrial, service or any other public or non-dwelling use then you have a legal requirement to keep the electrical system safe at all times. This applies to all business, regardless of size and includes sole traders.
Whilst the law does not state specifically that you must have an EICR, in practice EICR is the only way to ensure the system is safe and you are fulfilling your legal responsibilities. If an accident does occur because of your electrical system, being able to produce an up to date EICR and / or maintenance records can act as proof that you fulfilled your legal responsibilities and that you are not criminally liable for the accident.
