Landlord EICR Failure Examples to Watch For

A damaged socket in a rented kitchen, an old consumer unit with no RCD protection, or wiring that has deteriorated behind a wall can all lead to an unsatisfactory report. These landlord EICR failure examples are not minor paperwork issues. They can point to electric shock, fire or overheating risks that need professional attention before a property can be considered safe for tenants.

For landlords in Blackpool and across the Fylde Coast, an Electrical Installation Condition Report is a practical check on the fixed wiring in a property. It does not test every appliance a tenant owns, but it does assess the installation that supplies them: the consumer unit, circuits, sockets, switches, lighting points, earthing and bonding.

What makes an EICR a fail?

An electrician records observations using classification codes. A report is normally recorded as unsatisfactory where it contains a C1, C2 or FI observation.

A C1 means danger is present. The risk requires immediate action, and the electrician may make the issue safe during the inspection with the landlord's agreement. A C2 means potentially dangerous. It may not be causing an immediate incident, but remedial work is required urgently. FI means further investigation is needed without delay because the inspector cannot confirm that part of the installation is safe.

A C3 observation is a recommendation for improvement. For example, a consumer unit might not meet the latest standard but still be safe and serviceable. A C3 on its own does not make an EICR unsatisfactory. This distinction matters because not every older installation needs a full rewire, but genuine safety defects must not be left in place.

In England, private landlords must generally have the electrical installation inspected and tested at least every five years, or sooner if the report recommends it. Where remedial work is identified, the regulations require it to be completed within 28 days, or sooner where the report specifies. A written confirmation of completion must then be provided to the relevant people. Requirements can vary by property type and tenancy arrangement, so advice should reflect the individual property.

Common landlord EICR failure examples

Missing or inadequate RCD protection

Residual Current Devices, known as RCDs, quickly disconnect the supply when they detect current flowing where it should not. They offer vital additional protection against electric shock and can reduce the risk from damaged leads, faulty equipment and certain faults to earth.

Older fuse boards may have no RCD protection at all, or only protect some circuits. A common issue is a socket circuit without appropriate RCD protection, particularly where sockets could reasonably be used to supply equipment outdoors. The correct code depends on the age, design and condition of the installation, which is why the inspector must assess the circuit rather than apply a blanket rule.

The remedy may be an RCD consumer unit upgrade, an RCBO upgrade, or targeted alterations. A replacement consumer unit is not automatically required in every case, but it is often the clearest long-term solution where protection is limited and the board is in poor condition.

Damaged sockets, switches and accessories

Cracked socket fronts, loose switches, exposed live parts and scorched accessories are among the clearest electrical safety concerns in rental homes. Damage can allow a tenant to touch live components or can indicate overheating within the accessory or wiring behind it.

A loose socket should never be dismissed as wear and tear. Movement can strain conductors, loosen terminations and create resistance. Resistance produces heat, and heat can damage insulation or start a fire. Where an accessory is visibly damaged or unsafe to use, it may be coded C1 or C2 depending on the circumstances.

Loose connections and signs of overheating

During an EICR, electricians inspect accessible connections and carry out testing to identify faults that cannot be seen. Brown marks around a socket, a burnt smell, melted insulation, heat-damaged terminals or a buzzing consumer unit all warrant immediate attention.

Loose connections are particularly concerning because they can worsen gradually. A circuit may continue working while the connection heats each time a kettle, heater or washing machine is used. In a busy rental property, that repeated loading can turn a hidden defect into a serious fire risk.

Poor earthing and bonding

Earthing and bonding are central to electrical safety. They provide a path for fault current and help protective devices disconnect the supply quickly if a fault develops. If the main earthing conductor is undersized, disconnected or inadequate, a metal appliance casing or pipework could become dangerous under fault conditions.

Inspectors also check main protective bonding to services such as gas and water where applicable. Missing or inadequate bonding is a frequent issue in older properties, especially after alterations to plumbing, meters or consumer units. The severity depends on the installation and test results, but it can lead to an unsatisfactory report.

Obsolete or deteriorated wiring

Age alone does not condemn wiring. Some older cable remains safe when its insulation, connections and protective measures are sound. However, deterioration is a different matter.

VIR cable, for example, can become brittle over time. Its insulation may crack when disturbed, leaving conductors inadequately protected. Old rubber-insulated cables can present similar problems. If an electrician finds brittle, perished or exposed insulation, the affected circuits may require replacement and, in some properties, a partial or full rewire may be the safest option.

The scope of work depends on the extent of the defect. Replacing a short damaged section is sometimes possible, but patch repairs are not appropriate where deterioration is widespread or concealed within walls and ceilings.

Incorrect protective devices or circuit faults

Fuses, MCBs and RCBOs must be correctly selected for the cable and circuit they protect. An oversized protective device may fail to disconnect quickly enough during an overload or fault, allowing cables to overheat. Other issues include circuits that do not meet required disconnection times, poor insulation resistance readings, borrowed neutrals and polarity faults.

These defects are rarely visible to a landlord or tenant. A socket can appear to work normally while testing shows that it is incorrectly wired or unable to disconnect safely in a fault condition. This is precisely why visual checks are not a substitute for a proper EICR.

Unsafe alterations and DIY work

Rental properties often contain electrical alterations carried out over many years: an added shower circuit, garage supply, loft conversion, garden lighting or extra sockets. Problems arise when work has been completed without suitable design, testing or certification.

Warning signs include cables unsupported in a loft, joints hidden under floors without suitable enclosures, bathroom fittings in unsuitable locations, and circuits added to an already overloaded consumer unit. Not all previous work is defective, but undocumented alterations deserve close inspection. The electrician may need further investigation if safe verification is not possible at the initial visit.

What landlords should do after an unsatisfactory EICR

Do not treat the report as a quotation checklist alone. Read the observation schedule and ask the electrician to explain the classification, the risk and whether any circuit has been isolated. If a C1 has been identified, make sure the immediate danger has been addressed before tenants use the affected area or circuit.

For C2 and FI observations, arrange remedial work promptly with a competent electrician. Once the work and any required investigation are complete, obtain written confirmation that the issues have been remedied or that the installation now meets the required standard. Keep the original EICR, the remedial documentation and invoices with your property records.

It is also sensible to tell tenants what work is planned and how long access may be needed. Clear communication reduces disruption and helps avoid tenants attempting their own temporary repairs, such as taping over a broken socket or repeatedly resetting a tripping breaker.

Prevention is usually less disruptive than repair

Between inspections, landlords should take reports of tripping circuits, hot sockets, burning smells, flickering lights or damaged accessories seriously. These are not tenant maintenance jobs. Arrange a qualified electrician to investigate, particularly where there is a loss of power, signs of overheating or a suspected fault.

An EICR should give you a clear view of the fixed installation, not leave you guessing about what is safe. If your report identifies concerns, prompt, properly certified remedial work protects your tenants, your property and your responsibilities as a landlord.
