The primary legislation. Requires all electrical systems and equipment to be maintained to prevent danger. This is the main regulation that makes PAT testing effectively mandatory.
🔹 Health and Safety at Work Act 1974
General duty of care for employers to protect the health and safety of employees and the public.
🔹 IET Code of Practice for In-Service Inspection & Testing
The technical standard that defines how PAT testing should be carried out, including testing frequencies and pass/fail criteria.
🔹 Management of Health and Safety at Work Regulations 1999
Requires employers to conduct risk assessments, including assessments of electrical safety.
🔹 Provision and Use of Work Equipment Regulations 1998 (PUWER)
