What Does an EICR Check in Your Property?

An Electrical Installation Condition Report is not simply a quick look inside a fuseboard. If you are asking, “what does an EICR check?”, the answer is that it assesses the safety and condition of the fixed electrical installation in a property. It is designed to identify faults, deterioration and non-compliance that could create a risk of electric shock, fire or injury.

For homeowners, landlords and business owners across Norfolk and Suffolk, an EICR provides a clear picture of whether the wiring and associated fixed equipment are safe for continued use. It also gives you properly recorded evidence of the installation’s condition, rather than relying on assumptions about its age or appearance.

What Does an EICR Check?

An EICR checks the fixed electrical installation, meaning the parts of your electrical system that are permanently installed. This includes the consumer unit or fuseboard, wiring, sockets, switches, light fittings, circuits, earthing and bonding arrangements, and fixed equipment connected to the installation.

The inspection is carried out by a competent electrician using a combination of visual checks and electrical testing. Some tests are completed with the power isolated, while others require circuits to be energised. The aim is to confirm that protective measures will operate correctly if a fault occurs, and that the installation does not show signs of damage, unsafe alteration or excessive wear.

An EICR does not normally test every portable appliance plugged into a socket. Portable appliance testing, often called PAT testing, is a separate service. Likewise, an EICR cannot guarantee that an electrical fault will never develop after the inspection. It is a report on the installation’s condition at the time it is inspected.

The Main Areas Included in an EICR Inspection

The scope of an EICR depends on the size, age and layout of the property, as well as any agreed limitations on access. A thorough inspection will usually consider the condition of the consumer unit, circuit protection, electrical accessories and visible wiring throughout the property.

The electrician will check whether the earthing and main protective bonding are present and correctly connected. These are essential safety measures. In the event of a fault, they help give electricity a safe path to earth and support the operation of protective devices.

Testing also checks the effectiveness of circuit protection. Modern installations commonly use residual current devices, known as RCDs, or RCBOs. These devices are designed to disconnect the supply rapidly where there is a dangerous imbalance or fault. An EICR helps establish whether they are fitted where required, operate within the expected limits and protect the appropriate circuits.

Other checks can reveal issues such as:

• damaged, deteriorated or poorly installed cables and accessories;

• overloaded circuits or unsuitable protective devices;

• signs of overheating at connections, switches, sockets or the consumer unit;

• missing covers, exposed live parts or inadequate enclosures;

• unsuitable DIY alterations, poor previous workmanship or outdated protective arrangements.

Not every observation means the property is immediately dangerous. However, it is always better to understand the condition of the system before a small issue becomes a disruptive or expensive repair.

Visual inspection and electrical testing work together

A visual inspection can identify obvious concerns, such as cracked sockets, loose fittings, scorch marks or an old fuseboard with rewireable fuses. But many of the most significant electrical defects are not visible from the surface.

Electrical test instruments allow the electrician to measure continuity, insulation resistance, polarity, earth fault loop impedance and RCD performance. In plain English, these tests help establish that wiring is connected correctly, insulation is sound, protective devices can disconnect in a fault condition, and the earthing system is capable of doing its job.

This is why an EICR should not be treated as a box-ticking exercise. A well-presented property can still have hidden faults, particularly where it has been extended, altered or repeatedly renovated over many years.

What the EICR Results Mean

Once the inspection and testing are complete, you receive a written Electrical Installation Condition Report. It will record the installation details, circuits inspected, test results, observations and any limitations that affected the inspection.

The overall outcome will normally be either satisfactory or unsatisfactory. A satisfactory report means no observations were found that require urgent remedial work under the reporting codes. It does not mean the installation is brand new or that there are no recommendations at all.

Where faults are found, the report uses classification codes to show their level of urgency:

• C1 - Danger present. There is an immediate risk and urgent action is needed. Where safe and agreed, the electrician may make the issue safe before leaving.

• C2 - Potentially dangerous. The issue is not necessarily causing immediate danger, but it could become hazardous and should be remedied promptly.

• FI - Further investigation required. A potential problem has been identified but cannot be fully assessed during the inspection. Further work is needed without delay.

• C3 - Improvement recommended. The installation may not meet the latest standards, but the issue does not make the report unsatisfactory on its own.

A C1, C2 or FI observation will normally result in an unsatisfactory report. This is not a reason to panic. It is a clear, prioritised record of what needs attention, allowing repairs to be planned properly. A trustworthy electrician should explain the findings in straightforward terms and provide a transparent quotation for any recommended remedial work.

When Is an EICR Needed?

For landlords in England, electrical safety regulations require the fixed installation in privately rented homes to be inspected and tested at least every five years by a qualified person. A copy of the report must also be provided to tenants and retained as part of the landlord’s compliance records. If the report identifies remedial work, this must be completed within the required timescale, usually 28 days or sooner if the report specifies it.

For owner-occupied homes, an EICR is not generally a legal requirement at fixed intervals. It is still strongly advisable when buying an older property, before major renovation work, after flood or fire damage, if there are persistent electrical faults, or where the installation has not been assessed for many years. A typical recommendation for an owner-occupied home is every ten years, although the appropriate interval depends on the installation and how it is used.

Commercial properties need particular care. Offices, shops, workshops, holiday lets and communal areas can have heavier use, more equipment and greater responsibilities towards staff, customers and visitors. The recommended inspection interval may be shorter, depending on the type of premises, environmental conditions, usage and insurer requirements. A busy workshop, for example, should not be approached in the same way as a low-use office.

What Happens If Your EICR Is Unsatisfactory?

An unsatisfactory EICR tells you that action is required, but the next step depends on the specific observations. A missing RCD may point towards a consumer unit upgrade. Failed insulation resistance may require fault-finding and repair to a circuit. Inadequate main bonding may be resolved with a targeted upgrade, while widespread ageing or unsafe wiring could make a partial or full rewire the more sensible long-term choice.

The cheapest repair is not always the best value. Repeatedly repairing an outdated installation can become costly and disruptive, particularly if the consumer unit, earthing arrangements and several circuits all need attention. On the other hand, a report may identify only a few localised defects that can be rectified efficiently. The right solution should be based on the report findings, the property’s future plans and a clear explanation of costs.

After remedial work, you should receive appropriate certification or confirmation that the specified issues have been corrected. For landlords, this evidence is especially important, as it demonstrates that the report’s required remedial actions have been addressed.

Preparing for an EICR Visit

The inspection is easier and more complete when the electrician can access the consumer unit, sockets, switches, cupboards and areas where electrical equipment is installed. Let them know in advance about extensions, outbuildings, electric showers, EV chargers, solar equipment, recent alterations or known faults such as tripping circuits.

There may be short periods without power while tests are completed, so it is sensible to save computer work, plan around alarms and avoid scheduling the visit when uninterrupted electricity is essential. In a commercial setting, agreeing access and shutdown times beforehand can reduce disruption for staff and customers.

If certain areas cannot be accessed, this will be recorded as a limitation on the report. That does not automatically mean the EICR is invalid, but it can affect how complete the assessment is. Full access gives the clearest and most useful result.
