Four documents get called an "electrical certificate". They do different jobs, and buyers, landlords and insurers ask for different ones.

EICR: Electrical Installation Condition Report

A report on the condition of an existing installation. It's what landlords need every five years and what buyers ask for. It doesn't certify any new work. See EICR inspections.

EIC: Electrical Installation Certificate

Issued for new work: a new installation, a rewire, a new circuit or a consumer unit replacement. It records the design, construction, inspection and testing, and it is signed by the people responsible. A full EIC can stand in for a landlord's EICR until five years after its date.

Minor Electrical Installation Works Certificate

For small additions and alterations that don't add a new circuit, such as an extra socket on an existing circuit, a replacement light fitting or a moved switch. It shows the work was tested and is safe. Keep these. They're part of the property's electrical history.

Building regulations (Part P) compliance certificate

Some electrical work in homes is notifiable under Part P of the Building Regulations: in England, mainly a new circuit, a consumer unit replacement, and additions or alterations to circuits in rooms with a bath or shower. Notifiable work must either be done by an electrician registered with a competent person scheme, who self-certifies and notifies building control, or be notified to building control directly before work starts. The homeowner then receives a compliance certificate. Solicitors ask for these when you sell.
