London EICR Advice
Why Does My Property Keep Receiving an
Unsatisfactory EICR Report?
Your property is probably receiving an unsatisfactory EICR because
one or more electrical defects have not been fully resolved.
The most common causes include damaged wiring, poor earthing, missing
RCD protection, unsafe alterations or faults inside the consumer unit.
A report containing C1, C2 or FI observations will normally be marked
unsatisfactory. The next step is to deal with the exact issues listed,
keep evidence of the completed work and arrange any follow-up testing
recommended by the inspector.

⚠️
Why It Failed
C1, C2 or FI observations normally make an EICR
unsatisfactory.
🔌
Common Faults
Old wiring, poor earthing and weak circuit protection
are frequent causes.
🛠️
What Fixes It
Targeted repairs may be enough. A complete rewire is
not always needed.

evidence of the repairs.

Why Does an EICR Keep Coming Back Unsatisfactory?
Repeated failure usually means the original problem was only partly
repaired. A socket may have been replaced while damaged wiring,
a loose connection or poor earthing remained elsewhere on the circuit.
New alterations can also create fresh defects. This often happens
when electrical work is added without proper testing or certification.
A thorough
Professional EICR Inspection
checks the installation as a whole rather than looking only at the
most visible fault.
Damaged or deteriorated wiring
Poor earthing or bonding
Missing or unsuitable RCD protection
Unsafe previous alterations
📑
What Do C1, C2, C3 and FI Actually Mean?
These codes show how serious each observation is. C1, C2 and FI
normally make the overall report unsatisfactory. C3 is a recommendation
for improvement and does not usually cause failure on its own.
C1
Danger Present
There is an immediate risk. The condition must be made safe
straight away.
C2
Potentially Dangerous
The fault requires urgent remedial work, even if no accident
has happened yet.
C3
Improvement Recommended
The installation can still be satisfactory, but an upgrade
would improve safety.
FI
Further Investigation
More testing is needed before the inspector can confirm the
cause or seriousness of the issue.
🏠
Are Old Wiring and Consumer Units Always the Problem?
Not always. An older installation can still be safe if it remains in
good condition and has suitable protection. Problems begin when cables
deteriorate, earthing is inadequate or the consumer unit no longer
protects the circuits properly.
Some properties need targeted repairs. Others may benefit from
Consumer Unit Upgrades
or, where the wiring has seriously deteriorated,
Electrical Rewiring
.
The inspection findings should guide that decision.
Loose consumer unit connections
Damaged cable insulation
Incorrect protective devices
Inadequate protective bonding
🚨
Does a Failed EICR Mean the Property Is Immediately Dangerous?
No. A C1 means danger is already present and immediate action is
required. A C2 means the fault is potentially dangerous and should
be repaired urgently. FI means the inspector needs more information
before reaching a final conclusion.
Do not ignore any of these codes. If a circuit has been isolated,
leave it switched off until suitable
Electrical Fault Finding and Repairs
have been completed.
🔑
What Should a Landlord Do After an Unsatisfactory Report?
Start by reviewing every C1, C2 and FI observation with a qualified
electrical professional. Arrange the required work within the period
stated in the report and keep written proof that it was completed.
For regulated rented properties in England, remedial work or further
investigation is generally required within 28 days, or sooner if the
report gives a shorter deadline. Clear records help protect both the
landlord and the tenant.

Complete any further investigation
Keep certificates and written evidence
What Repairs Are Usually Needed Before the EICR Is Satisfactory?
The answer depends on the report. Common work includes repairing
damaged wiring, improving earthing, correcting RCD protection,
replacing unsafe accessories and fixing consumer unit defects.
A full rewire is only needed when the condition of the installation
genuinely justifies it.
