Electrical Installation Certificate (EIC)

What is an Electrical Installation Certificate (EIC)?

BS 7671 – British Standard – also known as the IEE (Institute of Electrical Engineering) wiring regulations is the standard that all electrical installations must adhere to.

An electrical installation certificate is issued for all new electrical installations, and may also be a requirement for an alteration or addition to a current electrical installation. An EIC confirms that the electrical installation work has been carried out and tested in accordance with British Standard BS 7671 (IEE Wiring Regulations). It is a legal requirement for an electrical contractor to issue an electrical installation certificate (EIC) upon completion and testing of electrical works.

Where an alteration or addition is carried out but does not include a new circuit, either an Minor Electrical Installation Works Certificate (MEIWC) or an Electrical Installation Certificate (EIC) may be used.

An Electrical Installation Certificate is required for:

  • New installations
  • When a new electrical circuit(s) is installed to an existing installation
  • The changing of a domestic consumer unit (distribution board / fuse board)
  • When a circuit is altered, requiring a change of the protective device.

A valid Electrical Installation Certificate must be accompanied by a:

  • Schedule of Inspections
  • Schedule of Test Results.

The original version of the Electrical Installation Certificate must be given to the building owner or person ordering the electrical work. A copy should be kept by the electrical contractor who completed the electrical inspection and testing.
