What Does an EICR Say If a Property Needs Rewiring?
What Does an EICR Say If a Property Needs Rewiring?
An Electrical Installation Condition Report (EICR) does not simply state “this property needs rewiring”.
Instead, it identifies specific defects and classifies them using coded observations. Where widespread wiring issues are found, the overall recommendation may indicate that a full or partial rewire is required.
If you are concerned about your installation, you can find full details of our House Rewiring services in Altrincham.
How EICR Coding Works
During an inspection, observations are categorised as:
- C1 – Danger present (immediate risk)
- C2 – Potentially dangerous
- C3 – Improvement recommended
- FI – Further investigation required
A report containing C1 or C2 observations is considered unsatisfactory.
When Would an EICR Suggest Rewiring?
Rewiring may be recommended where the report identifies:
- Deteriorated or damaged cable insulation
- Obsolete wiring types (rubber, fabric, lead-sheathed)
- Lack of protective conductors (no earth)
- Extensive non-compliant alterations
- Repeated C2 observations across multiple circuits
In these cases, isolated repairs may not be sufficient.
Does an Unsatisfactory EICR Automatically Mean a Full Rewire?
No.
An unsatisfactory report simply means remedial work is required.
Sometimes this involves:
- Replacing specific circuits
- Upgrading the consumer unit
- Improving earthing and bonding
- Correcting historic installation faults
A full rewire is only recommended where defects are widespread or structural.
What Would the Report Actually Say?
The EICR itself will list individual observations. In more serious cases, it may include wording such as:
- “Installation shows signs of age-related deterioration”
- “Wiring system not suitable for continued service”
- “Extent of non-compliance suggests consideration of full replacement”
A qualified electrician will then explain whether partial or full rewiring is proportionate.
Can a Landlord Let a Property That Needs Rewiring?
If the EICR contains C1 or C2 observations relating to unsafe wiring, remedial work must be completed within the required timeframe.
If rewiring is the recommended corrective action, it must be carried out before the installation can be considered satisfactory.
Should I Get a Second Opinion?
If a report recommends rewiring, it is reasonable to ask:
- Which specific circuits are defective?
- Is deterioration localised or widespread?
- Would partial replacement resolve the issue?
Rewiring should be evidence-based, not assumed.
