When it comes to electrical safety and compliance in the UK, two essential certificates come into play: the EIC (Electrical Installation Certificate) and the EICR (Electrical Installation Condition Report). While they may sound similar, they serve distinct purposes and are used in different scenarios.
At NICEIC Electricians, we believe property owners, landlords, and businesses should clearly understand when and why each certificate is needed. Here's a simple, expert explanation of both.
What Is an EIC (Electrical Installation Certificate)?
An EIC is a certificate issued after new electrical installation work is carried out. This includes full or partial rewires, installation of a new consumer unit (fuse box), or the addition of new circuits.
It confirms that the electrical work:
-
Was installed by a qualified professional
-
Complies with BS 7671 Wiring Regulations
-
Is safe for use from the day of completion
When is an EIC required?
-
Full rewiring of a property
-
Installing a new consumer unit
-
Adding new circuits to an existing system
-
Electrical installations in a new-build home
NICEIC Electricians issue EICs for all qualifying works. The document includes details of the installation, test results, materials used, and the identity of the contractor.
What Is an EICR (Electrical Installation Condition Report)?
An EICR, on the other hand, is a routine inspection of existing electrical installations. It assesses the safety, condition, and compliance of the electrical system over time—not just after installation.
Think of the EICR as an MOT for your electrics. It doesn't follow new work but checks the ageing installation for risks or degradation.
When is an EICR required?
-
Every 5 years in rental properties (legal requirement)
-
When buying or selling a home
-
As part of routine maintenance for businesses
-
After significant damage, flooding, or fire
The EICR will highlight any faults or potential dangers using codes:
Key Differences Between EIC and EICR
| Feature |
EIC |
EICR |
| Purpose |
Certifies new electrical work |
Assesses condition of existing installation |
| Legal Requirement |
Required for new installations |
Required for rented properties (every 5 yrs) |
| Issued When |

Qualified inspector/tester |
| Validity Period |
Valid until modified |
Typically 5 years for landlords |
| Includes Fault Codes? |
No |
Yes (C1, C2, C3) |
Can You Have Both?
Yes. A property may have a valid EIC for recent work and still require an EICR for overall safety. For example, upgrading your fuse box may be accompanied by an EIC, but an EICR would still be needed to assess older circuits elsewhere in the property.
Which Certificate Do I Need?
-
If you’ve just had electrical work completed: EIC
-
If you’re a landlord or selling a property: EICR
-
If you’re unsure about the condition of your wiring: EICR
-
If you’re modifying circuits: EIC + Minor Works Certificate
