Electrical Installation Certificate (EIC) Guide

Understand when an EIC is used, how it differs from an EICR and why inspection, testing and Building Regulations notification are separate issues.

What is an Electrical Installation Certificate?

An Electrical Installation Certificate records certain new electrical installation work or significant alterations after the work has been designed, installed, inspected and tested. It identifies the extent of the work, the people responsible for design, construction and verification, and the relevant test results.

EIC and EICR are not the same

An EIC relates to newly completed installation work. An Electrical Installation Condition Report assesses the condition of an existing installation at the time of inspection. One document does not replace the other.

Why the existing installation still matters

New work connects to something that already exists. Relevant earthing, bonding, circuit protection and conductor condition need to be suitable for the alteration. If testing reveals a defect that directly affects safe completion of the new work, it cannot simply be ignored because it was not visible at quotation stage.

Minor Works Certificate

Smaller additions and alterations that do not include a new circuit may use a Minor Electrical Installation Works Certificate where appropriate. The correct certificate depends on the actual work carried out.

Part P and Building Regulations

Electrical certification and Building Regulations notification are related but separate. An EIC records electrical installation work; a Building Regulations compliance certificate provides evidence that qualifying notifiable work was notified through the relevant route. Receiving one does not automatically prove the other process happened.

What customers should keep

Keep electrical certificates with property records. They can help future electricians understand alterations and may be requested during a sale, mortgage process or later renovation.
