Electrical Installation Certificate (EIC)

An Electrical Installation Certificate (EIC) is issued when new electrical work is completed, such as a new circuit, consumer unit replacement, or rewire. It confirms the installation has been designed, constructed, inspected, and tested to BS 7671 (IET Wiring Regulations). The EIC must be issued by a qualified electrician and, for notifiable work, submitted to Building Control via a Competent Person Scheme.

BS 7671 IET Wiring Regulations, Building Regulations Part PValid: Permanent (issued once for the installation)

What it covers

  • Details of the electrical installation and circuits
  • Design, construction, and inspection verification
  • Schedule of test results (Zs, insulation resistance, RCD trip times)
  • Circuit schedule with protective devices
  • Declaration of compliance with BS 7671

Who needs a EIC?

Homeowners having electrical work done
Landlords
Building Control

Frequently asked questions about EIC

When is an EIC required?
An EIC is required for all new electrical installations and additions — consumer unit replacements, new circuits, rewires, and any notifiable work under Part P of the Building Regulations.
What is the difference between an EIC and a Minor Works certificate?
An EIC covers new installations and circuits. A Minor Works certificate covers small alterations to existing circuits (e.g. adding a socket to an existing ring). If you're adding a new circuit, you need an EIC.
Does CertBox validate Zs readings?
Yes. CertBox checks that measured Zs values don't exceed the maximum permitted values for each circuit's protective device. If a reading is out of range, you'll see a warning before you can submit.
Do I need to notify Building Control?
For notifiable work (new circuits, consumer unit changes, work in bathrooms/kitchens, outdoor circuits), yes. If you're registered with a Competent Person Scheme (NICEIC, NAPIT, etc.), your scheme self-certifies to Building Control.
