We’re often carrying out audits and gap analysis surveys on behalf of our clients and one things which repeatedly creates questions is the requirement for periodic electrical inspections of the electrical supply system.

Most of us are familiar with the general requirement but few of us are clear on why and how often might be considered reasonable and so we’ve done our best to give this advice below.

Electrical inspections: Are these tests required by law?

Good question! The answer is yes and also no, they are not written into clear and specific legislation but they are related to a requirement made under the Electricity at Work Regulations (Reg 4). This requires that all electrical installations are maintained, so far as is reasonably practicable, to prevent danger.  So although no strict duty exists the inference is that you must take clear steps to ensure you comply with regulation 4, if you don’t carry out the regular tests required you can’t really show you are complying.  So the answer is that yes, you do need to carry out these inspections.

How often must I carry out these tests?

Another good question! The guidance issued in the 17th Edition of the IEE Wiring Regulations and IET Guidance Note 3 are technical guides intended for reference by electricians but we can extract some good guidance on recommended frequencies;

• General commercial, educational establishments, hospitals, churches: every 5 years
• Industrial premises. leisure complexes, agriculture and entertainment: every 3 years
• Swimming pools, medical areas of healthcare premises, filling stations, caravan sites: annually

Your next steps

You don’t have to follow the above by law but you do have to show that you are doing something to comply with Regulation 4, and in practice this means doing what is described above.  If you chose not to then you must be ready to defend your actions in court should an incident occur (your insurer may also be concerned if you fail to carry out these tests).

We’d also suggest an annual visual inspection to ensure that any obvious defects are identified – consult with your electrician for more advice and if you have specific questions then contact us to some more advice.
