The COES system explained

The Electricity Safety Act 1998 and Electricity Safety (Installations) Regulations 2009 require a Certificate of Electrical Safety (COES) to be issued for all electrical installation work.

Failure to comply with these requirements is a criminal offence and licensed workers who do so may be subject to disciplinary action which could result in the suspension or cancellation of their licence.

A guide to using COES

ESV has produced A practical guide to using COES which explains time frames for the lodgement of the different types of certificates (prescribed and non-prescribed) and frequently asked questions.

Types of COES

There are three types of certificates:

  1. Prescribed
  2. Non-prescribed
  3. Periodic

  

Prescribed COES

Prescribed electrical installation work is required to have a prescribed COES issued for the work.

Copies of prescribed COES must be provided to the relevant parties within 14 calendar days from completion of the work.

Prescribed COES must be sent to the customer, the Licensed Electrical Inspector (LEI), the distribution business and ESV. The responsible person is to keep their copy for three years.

Failure to comply with these requirements is an offence.

See a list of installation work classed as prescribed, here.

Non-prescribed COES

Non-prescribed electrical installation work is required to have a non-prescribed COES issued.

Non-prescribed COES must be sent to the customer and ESV. The responsible person is to keep their copy for three years.

Failure to comply with these requirements is an offence.

See a list of installation work classed as non-prescribed, here.

Periodic COES

Periodic COES allow non-prescribed electrical installation work to be performed at a single electrical installation for a period of three months.

One copy of a periodic COES (the customer copy) is to be sent/retained by the business where the electrical installation work was completed. One copy is to be kept by the responsible person (the person who has their user ID allocated to the COES) and one copy sent to ESV.

Legislation, Regulations and Exemptions applicable to COES

Order G17 of 1999 (Consolidated version) See: Part2, clause 1 and Part 3.

Order G50 of 1999 See: Part 1.

Order G36 of 2000 See: Clause 3.
