What is an Electrical Installation Certificate (EIC)?
By Azzeddine Kebbi, NAPIT-registered electrician and director of Kebbi Electrical Services · Updated 10 November 2026
An Electrical Installation Certificate (EIC) is the certificate your electrician gives you after new electrical work, such as a new circuit, a new consumer unit or a rewire. It confirms the work was designed, installed, inspected and tested to the UK Wiring Regulations, BS 7671.
When you should get one
- A full or partial rewire.
- A new consumer unit (fuse board).
- Any new circuit, for example for a shower, cooker, EV charger or extension.
Smaller jobs on an existing circuit get a Minor Works Certificate instead.
What it includes
Declarations
Signed sections for design, construction and inspection and testing.
Schedule of inspections
A checklist of what was inspected.
Schedule of test results
Readings for every circuit, proving it is safe.
Supply details
The earthing arrangement and main protective devices.
EIC, EICR or Minor Works?
EIC
New installations and new circuits.
Minor Works Certificate
Small additions or changes to an existing circuit.
EICR
A report on the condition of an existing installation, not a certificate for new work.
Common questions
Who issues an Electrical Installation Certificate?
The electrician who did the work. A registered electrician (for example NAPIT) also notifies building control for notifiable work, and you receive a Building Regulations Compliance Certificate.
Is an EIC the same as a Part P certificate?
No. The EIC is the electrician’s technical certificate. The Part P (Building Regulations Compliance) certificate comes from their scheme. See what is a Part P certificate.
How long is an EIC valid for?
It does not expire. It records the work at the time it was done. The installation should then be checked periodically with an EICR.
What if I did not get an EIC?
Ask the electrician who did the work. If you cannot get one, an electrician can inspect and test the installation and report on its condition with an EICR.
