If you are asking what does an EICR check, the short answer is this: it checks whether the fixed electrical installation in a property is safe for continued use. That means the wiring, consumer unit, earthing, bonding, sockets, switches, light fittings and other permanent electrical parts are inspected and tested to spot damage, wear, poor workmanship or anything that could lead to electric shock or fire.
For homeowners, landlords and business operators, that matters because many electrical faults stay hidden until there is a serious problem. An EICR is designed to catch issues before they become dangerous, disruptive or expensive.
What does an EICR check in practical terms?
An EICR stands for Electrical Installation Condition Report. It is not the same as testing a kettle, checking portable appliances or installing a new circuit. It is a formal inspection of the fixed electrics in the building.
In practical terms, an electrician is checking whether the installation meets an acceptable safety standard and whether any part of it has deteriorated over time. A property can still have power and appear to work normally while hiding faults behind walls, in the consumer unit or at connection points.
This is why an EICR focuses on condition, compliance and risk rather than just whether the lights turn on.
What an electrician will inspect during an EICR
The inspection starts with a visual assessment. This covers obvious signs of damage, ageing, overheating, poor previous alterations or components that are no longer suitable. The electrician will look at the consumer unit, protective devices, wiring accessories, visible cable routes and the general standard of the installation.
They will also check earthing and bonding arrangements. These are critical safety measures that help prevent electric shock. If these are missing, undersized or incorrectly connected, the risk level rises quickly.
Testing then goes further than what can be seen. Electrical circuits are checked to confirm they disconnect properly in a fault, that insulation is still performing as it should, and that polarity is correct. RCDs, if fitted, are tested to make sure they trip within the required time.
An EICR may also identify older installations that were acceptable when first installed but no longer meet current expectations for safety. That does not always mean a full rewire is needed, but it can mean remedial work is recommended.
The main parts an EICR check covers
Consumer unit and protective devices
The consumer unit is one of the first places an electrician will assess. They will check the condition of the enclosure, whether it is suitable for the installation, whether circuit labelling is clear and whether protective devices such as MCBs and RCDs are present and operating correctly.
Older fuse boards are not automatically unsafe, but many no longer offer the level of protection expected today. If there is no RCD protection where it should be, that will often be flagged.
Wiring and circuit condition
Cables are inspected where accessible, along with the results of electrical testing on each circuit. The aim is to identify deterioration, damaged insulation, overloaded circuits or signs that work has been carried out poorly in the past.
This part matters most in older homes, rented properties and commercial units that have seen repeated alterations over the years.
Earthing and bonding
Earthing and bonding are often misunderstood, but they are central to electrical safety. The electrician checks whether the main earthing arrangement is present and adequate, and whether bonding to services such as gas and water is correct.
If these protective measures are not in place, a fault could make exposed metalwork dangerous.
Sockets, switches and fittings
Sockets, switches and light fittings are checked for wear, damage and suitability. Cracked accessories, signs of overheating or loose connections can all be warning signs.
The electrician is not simply judging appearance. Even minor damage can suggest deeper issues behind the faceplate or on the circuit itself.
Bathrooms, kitchens and outdoor circuits
Areas with higher risk get close attention. Bathrooms, kitchens, garden supplies and outbuildings often involve moisture, metalwork and heavier electrical demand, so they need the right protection.
If circuits in these areas are not properly protected, or if fittings are unsuitable for the environment, they may be coded in the report.
What an EICR does not check
This is where confusion often starts. An EICR does not usually cover portable appliances such as kettles, toasters, desk lamps or extension leads. That is a different process, often called PAT testing.
It also does not act as a guarantee that no future fault will occur. Electrical systems can deteriorate over time, and misuse or later alterations can introduce new problems after the inspection.
An EICR is a snapshot of the installation’s condition on the day it is inspected and tested. It is thorough, but it is not a lifetime pass.
What the report codes mean
Once the inspection is complete, the report will include observations with classification codes. These codes show how serious any issue is.
A C1 means there is immediate danger and urgent action is required. A C2 means the issue is potentially dangerous and should be addressed as soon as possible. A C3 means improvement is recommended, even if the item is not considered dangerous at present. There may also be an FI code, which means further investigation is needed because something could not be fully assessed or a possible issue was found.
If a report includes C1 or C2 observations, or an FI, it will usually be marked unsatisfactory. That does not always mean the whole installation is poor. It means one or more findings require attention before the installation can be considered satisfactory.
When you should have an EICR carried out
It depends on the type of property and how it is used. For landlords, EICRs are a legal requirement in many rented properties, and inspections must be carried out at the correct intervals. For homeowners, an EICR is strongly advised if the property is older, if you have just bought it, if major alterations have been made, or if the electrics have not been checked in years.
For commercial premises, regular inspection is part of maintaining compliance and protecting staff, customers and operations. In offices, shops and hospitality spaces, small electrical defects can quickly become safety issues or cause downtime.
A good rule is simple: if you do not know when the fixed electrics were last inspected, it is probably time to arrange one.
What happens if faults are found?
In many cases, faults identified during an EICR can be put right without major disruption. Typical remedial work might include replacing damaged accessories, improving bonding, fitting the right protective devices or correcting issues in the consumer unit.
Sometimes the findings are more significant, especially in older properties with dated wiring or a history of piecemeal additions. Even then, the value of the report is clarity. You know what is wrong, how serious it is and what should happen next.
That is far better than guessing or waiting for a fault to force the issue.
Why an EICR is worth doing before problems appear
Most people do not book an electrical inspection because everything is going well. They book one because they are buying, letting, refurbishing, managing risk or dealing with a concern. But the best time to have an EICR is often before there is any obvious sign of trouble.
Electrical faults do not always announce themselves with sparks or power cuts. They can sit quietly in loose connections, overloaded circuits or ageing insulation. The cost of identifying those issues early is usually far lower than the cost of fire damage, emergency repairs or failed compliance checks later.
For property owners who want confidence, that is the real point of the report. It turns an unknown into a clear, professional assessment.
Choosing the right electrician for an EICR
Because an EICR is a formal safety document, it should be carried out by a qualified electrician with the right testing experience. This is not a box-ticking exercise. The quality of the inspection, the accuracy of the coding and the clarity of the advice all matter.
For landlords and businesses especially, a vague or rushed report can create more problems than it solves. You need a contractor who can test properly, explain findings in plain English and handle any remedial work without unnecessary delay.
If you are based in Bristol, Weston-super-Mare, Bridgwater, Bath or nearby areas, working with an established local contractor can also make follow-up work easier if the report identifies issues that need attention.
An EICR is not just about compliance. It is about knowing your electrics have been checked properly and that any risks have been identified before they turn into something more serious. If your property has not been inspected for some time, getting a clear answer now is usually the safest and simplest next step.
