Electrical Installation Condition Report - Explained
Despit sometimes being referred to as a certificate, this is actually a report on the condition of the installation at the time of inspection and test. It is required to be renewed on a regular basis:
Every Year
High-risk areas like swimming pools, saunas, and petrol stations.
Every 3 Years
Industrial units, factories, theatres, and caravan parks.
Every 5 Years
Standard commercial properties (offices, shops), HMOs (Houses in Multiple Occupation), and private or social rental homes.
N.B. Rental properties additionally require re-testing when a new tenant moves in.
Every 10 Years
Owner-occupied residential homes, excluding mobile homes.
What’s Involved?
The inspection generally takes around an hour and a half for a small property, whilst complex electrical installations can take much longer. During the inspection, the incoming supply and each circuit undergo rigorous testing—including continuity, insulation resistance, and earth fault loop impedance checks. This verifies the structural integrity of the wiring, and confirms that all earthing and bonding are secure and fully effective. It also compares the installation to the latests standards.
The power will have to be switched off on some or all of the circuits for most of the testing, so make sure you don’t start a washing cycle just before we arrive!
On completion, any issues identified will be discussed with you and the results are taken away to complete the report, which is emailed to you.
Any areas of concern are highlighted, and categorised as C1, C2 or C3. See table explaining the different codes
If you have a Satisfactory result, you can then keep one with with your consumer unit for easy reference, and share a copy with insurance companies, tenants, estate agents, etc as required. What’s more we will automatically remind you when renewal is due!
Should you receive an Unsatisfactory Result The electrician will prepare a quote for remedial work to be carried out. Your are at liberty to share the report with other electricians in order to obtain competitive quotes.
Key to Codes and what they mean to you:
Code C1 (Danger Present):
There is an immediate risk of injury or electric shock. The electrician must make this safe right away before leaving the property.
Examples: Exposed live wires, a cracked socket showing bare copper, or a burnt/melting consumer unit.
Code C2 (Potentially Dangerous)
The setup is not causing immediate danger right now, but it could become hazardous if another fault occurs or if conditions change. Urgent remedial work is required.
Examples: Missing RCD (safety switch) protection on outdoor sockets, or a complete lack of earthing to metal light fittings.
Code C3 (Improvement Recommended):
The installation is fully safe to use, but it does not match the latest modern regulations. It acts as an advisory note.
Examples: Outdated wire colours (old red/black vs modern brown/blue) or an older style of fuse box that still works safely.
Code FI (Further Investigation Advised):
The electrician has spotted something unusual or inconsistent during testing but needs extra time, specialized access, or deeper investigation to confirm if a true danger exists.
Examples: Unidentified circuits that won’t turn off, unexplained tracer voltages, or suspect product recalls on equipment.
Under BS 7671 Amendment 4 (2026), codes are explicitly split into two categories to give property owners better clarity:
Unsatisfactory Result:
If your report contains any C1 or C2 codes, the overall report is marked as Unsatisfactory, and you must arrange repairs to remain legally compliant.
Satisfactory Result:
C3 and FI codes are recorded separately as advisory observations. Under Amendment 4 rules, having an FI or C3 code on your report will not automatically make the overall EICR result unsatisfactory.
