This has come into being through the Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1992, and the Electricity at Work Regulations 1989, and is covered by the Institute of Electrical Engineers code of practice for In-Service Inspection and Testing of electrical equipment.

The frequency of tests depends upon several factors including the type of equipment, amount of usage, external influences, etc etc.

A low to medium risk such as an office would not normally require regular inspections, but should maintenance be carried out on
that equipment by an unqualified person you have just introduced a new risk. Or should that appliance have been given to you without
it being tested, once again you have immediately increased risk.

Should you require further clarification please do not hesitate to contact us.
