A C2 or C3 code on an inspection report is not paperwork. It marks a fault sitting inside the installation, waiting to cause damage. Too many landlords in London treat EICR remedial works as a box to tick, chasing a satisfactory result rather than safe wiring that holds up. The difference shows later, sometimes badly.
Codes Point at Faults, Not at Paperwork
What a Coded Observation Actually Records: Every coded observation names a measured or observed defect, recorded against the wiring regulations by the inspecting electrician. EICR remedial works exist to correct that defect at source. A code cleared without repair leaves the same danger in place, only now it sits behind a certificate that says otherwise. That is a worse position than failing.
Why Chasing a Cheaper Fix Backfires: Property owners compare quotes closely, and the EICR report cost sits alongside whatever repair follows. Squeezing the repair to protect the total rarely works out. Rewiring a damaged section properly costs less over five years than replacing the same circuit twice, plus the fine that follows a serious incident. Landlords learn this the hard way.
A Clean Certificate Cannot Switch off a Live Risk
Where Protection Fails Quietly: A residual current device that trips slowly, or fails to trip at all, gives no warning to anyone using the sockets above it. Swapping the front cover or tightening a terminal changes nothing. An electrician has to test the protective function and prove it, because occupants rely on it without ever thinking about it.
Repairs That Trace the Cause: Good EICR remedial works start with the question of why the fault appeared. A tripping circuit might point to moisture in an outbuilding feed rather than a faulty breaker. Fit a new breaker and the trip returns within weeks, along with another inspection and another set of observations. Perhaps that sounds obvious. It gets missed constantly.
Faults That Keep Returning after a Shallow Repair
Earthing and Bonding Get Overlooked First: Older London flats lose protective equipotential bonding to gas and water services more than any other item. A cable clipped near the meter looks convincing until someone checks the connection at both ends. Victorian conversions hide these gaps well, particularly where three flats share one riser. The report records a code. The cause sits in the cupboard.
- RCD protection missing on socket circuits, usually written up as a C2
- Damaged cable insulation behind kitchen units, buried by whoever fitted them
- Undersized earthing conductors left over from an older consumer unit
- Loose connections. Cheap to fix, genuinely dangerous to ignore
- Protective devices rated wrongly for the load the circuit now carries
Testing Proves the Work, Not the Invoice: Once repairs finish, the circuit needs retesting and a fresh record against the original observation. Some owners fixate on the EICR report cost and skip the verification stage, which leaves no evidence the fault ever cleared. Insurers ask for that evidence after a fire. Councils ask for it sooner. Neither accepts a verbal assurance.
Wiring You Can Stop Worrying About
Safe electrics come from repairs that answer the fault, followed by testing that proves the answer held. A satisfactory certificate then means something real to tenants, buyers and inspectors. Book a qualified electrician to review every coded observation on the latest report and carry out the repair properly. Waiting for the next inspection to catch it costs more.
