An Electrical Installation Condition Report (EICR) is more than just a certificate. It acts as a vital health check for the fixed wiring within a property. The report assesses whether your electrical systems are safe, secure, and in line with the current wiring standards. Ignoring electrical faults can lead to serious consequences such as electric shocks, fires, or complete system failure.
Electrical installations naturally deteriorate over time due to use and ageing. The EICR helps to catch these issues early, before they become dangerous. For homeowners, it provides reassurance. For landlords and businesses, it is a legal requirement under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. The general recommendation is every ten years for homeowners and every five years for rental properties or commercial premises.
If you’re not certain about the right time to arrange one, check out this basic guide on when and why inspections are needed.
EICR Coding Explained: How Results Are Categorised
When the inspection is completed, the results are given as a set of codes. These codes determine whether the installation passes or fails and help prioritise the necessary actions.
- C1 – Immediate Danger
This code flags a risk of injury or death from direct contact with live parts. It requires urgent disconnection and immediate remedial action. - C2 – Potential Danger
These are serious faults that may not be immediately dangerous but are likely to become hazardous. A C2 result will still mark the report as unsatisfactory and must be resolved quickly. - C3 – Improvement Recommended
This is a non-fail advisory. It suggests that something could be improved, such as updating an older system to match current regulations. It does not require urgent action but is worth addressing. - FI – Further Investigation Required
If an inspector finds something unusual but cannot determine the full extent during the assessment, they will mark it with FI. This means additional tests or access will be needed and the report will be classed as unsatisfactory until it is resolved.

Common Issues That Lead to an Unsatisfactory EICR
Outdated Consumer Units and Lack of RCD Protection
Many unsatisfactory reports are due to installations that are simply out of date. Older consumer units, especially those without Residual Current Device (RCD) protection, fail to meet modern safety standards. RCDs are designed to quickly cut off power in the event of a fault, reducing the risk of electrocution or fire. If your consumer unit still uses traditional fuses or lacks RCDs on all circuits, it will almost certainly be flagged.
Not only do these outdated units increase the risk of failure, but they also make maintenance more difficult and less reliable. Upgrading to a modern consumer unit with RCD protection is often one of the first recommendations following an unsatisfactory EICR.
Damaged Sockets, Switches and Accessories
Physical damage to sockets and switches is one of the most visible signs that an installation is unsafe. Cracked or burnt covers, loose fittings or signs of overheating are all considered fail points. Even if the wiring behind these fittings is sound, the outer damage can expose live parts and put users at risk.
Regular use wears down electrical accessories over time, especially in high-traffic areas or older properties. Replacing them with new, properly fitted accessories is usually straightforward but essential for safety compliance.
Poor or Inadequate Earthing and Bonding
A common fault in older or altered installations is the absence or deterioration of proper earthing and bonding. Without this, electrical systems cannot safely discharge fault currents, which increases the risk of electric shock. It’s particularly important in kitchens and bathrooms where metal fixtures could become live if not properly bonded.
Your EICR will test these safety features and flag any circuits that don’t meet the expected resistance values. If the earth connections are missing or not fit for purpose, immediate improvement will be necessary.
Overloaded Circuits and Loose Connections
Another frequent issue is circuit overloading. This happens when too many appliances are drawing power from a single circuit, leading to overheating and potential fire hazards. Similarly, loose connections can cause arcing, a condition where electricity jumps across gaps in wiring, creating sparks and heat.
Both problems are more common in properties that have undergone unregulated DIY work or have outdated layouts that haven’t been modernised to suit current energy demands. These faults will trigger either a C2 or FI code, depending on severity and evidence of risk.
Faulty or DIY Wiring Practices
DIY electrical work might seem like a money-saver, but it often leads to major EICR failures. Poor-quality wiring, incorrect connections, or illegal alterations create unpredictable safety risks. Inspectors often find non-standard cable colours, exposed junctions or circuits that don’t isolate correctly.
Any such work will almost always result in a failed EICR and will require correction by a qualified electrician. If you’ve moved into a property where DIY work was carried out by a previous owner, it’s worth getting a report even if you’re not legally required to.
Absence of Labelling or Circuit Identification
Labelling might not sound like a serious issue, but it’s a basic requirement of electrical safety. Without clear identification of each circuit at the consumer unit, it’s difficult to isolate and test individual parts of the system safely. During emergencies, poor labelling can delay response and increase risk.
EICR inspectors will flag missing or unclear labels, especially if circuits are mixed or extended. Although this may only result in a C3 code, it still contributes to an overall assessment of the installation’s condition.
What Happens After an Unsatisfactory EICR?
Legal Obligations for Landlords and Property Managers
When an EICR comes back as unsatisfactory, landlords are legally required to act. Under the regulations in England, any issues classified as C1, C2 or FI must be addressed within 28 days or sooner if specified by the report. Once the work is completed, a written confirmation must be obtained from a qualified electrician. This documentation should then be provided to the tenant and, if requested, to the local housing authority.
Failing to comply with these responsibilities can lead to hefty fines and enforcement action. The law does not allow landlords to ignore or delay remedial work, and regular inspections are expected to maintain electrical safety throughout the tenancy.
Timescales for Repairs and Retesting
Once faults are identified, it’s important to act swiftly. Urgent defects such as C1 must be made safe immediately, which often means turning off the affected circuit until it can be repaired. For other faults, you typically have up to 28 days. After corrections, a retest is essential to verify the safety of the installation. This retest may only cover the corrected areas or include a full reinspection depending on the extent of the faults.
Any delays or attempts to carry out unauthorised repairs can affect insurance coverage and put occupants at risk. It’s always better to get a qualified professional involved early.

Providing Confirmation of Remedial Work
After the remedial work has been completed, it must be certified. Electricians will usually provide either a Minor Electrical Installation Works Certificate or a new EICR confirming that the installation now meets safety standards. This paperwork is critical. It serves as proof that you’ve complied with legal obligations and protects you in case of future disputes or inspections.
If you’re a landlord, keep this documentation in your property records and share copies with tenants as required. Failure to do so could result in penalties even if the work itself was completed.
Avoiding an Unsatisfactory EICR Result
Regular Maintenance and Visual Checks
One of the most effective ways to avoid an unsatisfactory EICR is through regular maintenance. Even without opening up the consumer unit, there are visible signs that indicate wear or potential problems. These include discoloured sockets, buzzing switches, flickering lights, and exposed wires. Addressing these signs early prevents them from becoming larger safety issues during a formal inspection.
Regularly booking a visual inspection by a qualified electrician, especially before renting or selling a property, is a practical step that can identify emerging issues before they escalate into a reportable fault.
Employing Certified Electricians for Repairs
DIY work or hiring unqualified tradespeople is one of the main reasons installations fail EICR checks. Certified electricians are trained to follow BS 7671 standards and will ensure your installation complies with all the required regulations. Whether it’s a full rewire or simply upgrading a light fitting, using a registered electrician guarantees the work is safe and verifiable.
You can also ask for installation certificates or electrical installation condition reports after work is completed. These documents prove compliance and will be valuable during any future property transaction or letting process.
Keeping Electrical Records Up to Date
Maintaining proper documentation is just as important as the installation itself. Keep a file with all previous EICRs, installation certificates, and receipts for repairs. This record helps electricians identify previous issues and track the age and safety of your system over time.
It’s especially helpful for landlords or property managers overseeing multiple properties. When it’s time for a new report, an up-to-date record can help prevent unnecessary costs and ensure a quicker inspection process.
If you need professional assistance, consider speaking with electrical safety specialists to assess your property’s needs.
IET Wiring Regulations (18th Edition)
The IET Wiring Regulations, also known as BS 7671, set the benchmark for electrical safety in the UK. They cover the design, installation, and maintenance of electrical systems, and every EICR is assessed against these standards. The 18th Edition introduced stricter rules on RCD protection, surge protection devices, and cable installation methods. If your system doesn’t align with these expectations, it’s likely to receive an unsatisfactory rating.
Professionals use these regulations as their primary reference. Familiarising yourself with even the basics can help you understand the reasoning behind the recommendations found in your report. You can find the official regulations at the IET website.
Government Guidance on Electrical Safety Standards
For rental properties in England, the government mandates that landlords ensure electrical safety through EICRs every five years. The official government guidance outlines landlord duties, inspection frequencies, and steps to take after a report fails.
This document also explains the legal importance of C1, C2 and FI codes, and what documentation must be provided to tenants and local authorities. Landlords who fail to comply can be fined up to £30,000.
HSE: Electrical Safety Responsibilities
The Health and Safety Executive (HSE) plays a key role in setting and enforcing electrical safety expectations in workplaces and public premises. Their electrical safety at work guidance details employer obligations, maintenance routines, and how to manage risk with fixed installations. If you operate a commercial or industrial site, compliance with HSE advice is essential alongside EICR inspections.
Frequently Asked Questions
How often should an EICR be done?
The frequency depends on the type of property. For rental properties, it’s every five years by law. Homeowners are advised to have one every ten years, or when selling or buying a house. Commercial premises typically require an EICR every five years or more frequently if specified by insurance providers or local authorities.
Can I fail an EICR and still sell my house?
Yes, technically you can sell your house even if it has an unsatisfactory EICR, but it may reduce buyer confidence or affect the valuation. Buyers often request proof that electrical installations are safe, and a failed report can delay the sale until remedial work is completed. It’s best to address any fail codes before listing the property to avoid complications.
Is a C3 code something to worry about?
A C3 code does not fail an EICR. It simply means that an improvement is recommended. These are usually related to older practices that no longer meet current regulations but are not considered dangerous. While they don’t require immediate action, addressing C3 issues can improve safety and reduce future maintenance costs.
Final Thoughts
An unsatisfactory EICR result can be frustrating, but it serves a critical role in keeping properties safe and legally compliant. Understanding the report codes, recognising common issues, and knowing your responsibilities allows you to act confidently and quickly. Whether you’re a homeowner aiming for peace of mind or a landlord bound by regulation, proactive maintenance and professional guidance are your best defences against electrical hazards.
