An EICR test report is a legal and safety requirement for rental properties across the UK. It ensures that electrical installations are safe for continued use and helps landlords meet their legal obligations. However, many rental properties fail their EICR inspection—often due to issues that are common, preventable, and relatively straightforward to fix.

In this article, we’ll break down the most common EICR failures in rental properties, explain why they happen, and show you how to fix them to achieve a satisfactory EICR test report.

What Is an EICR Test Report?

An Electrical Installation Condition Report (EICR) assesses the safety of a property’s electrical systems, including wiring, sockets, fuse boards, and fixed electrical equipment. The report highlights defects using classification codes such as:

• C1 – Danger present (immediate action required)

• C2 – Potentially dangerous

• C3 – Improvement recommended

• FI – Further investigation required

A property fails an EICR test report if it contains any C1, C2, or FI observations.

1. Lack of RCD Protection

Why It Fails

Many older rental properties do not have Residual Current Devices (RCDs) installed, especially on socket circuits. RCDs are essential for protecting tenants from electric shock.

How to Fix It

• Upgrade the consumer unit to include RCD or RCBO protection

• Add RCD protection to specific circuits where possible

This upgrade often turns a failed EICR test report into a compliant one.

2. Outdated or Faulty Consumer Units

Why It Fails

Old fuse boards with rewireable fuses or signs of overheating are common causes of C2 failures.

How to Fix It

• Replace outdated fuse boards with modern consumer units

• Ensure proper labeling and circuit identification

A new consumer unit significantly improves safety and compliance.

3. Damaged or Deteriorated Wiring

Why It Fails

Over time, electrical cables can degrade due to heat, age, rodents, or poor previous workmanship.

How to Fix It

• Replace damaged cables

• Rewire affected circuits or, in severe cases, the entire property

Although rewiring can be costly, it ensures long-term safety and a pass on your EICR test report.

4. Incorrect Bonding and Earthing

Why It Fails

Missing or inadequate main protective bonding (to gas and water pipes) is a very common EICR failure.

How to Fix It

• Install correct earthing and bonding conductors

• Ensure bonding meets current wiring regulations (BS 7671)

This is usually a quick and affordable fix.

5. Overloaded or Unsafe Socket Outlets

Why It Fails

Overloaded sockets, cracked faceplates, or poorly installed extensions can result in C2 or C1 codes.

How to Fix It

• Replace damaged sockets

• Install additional socket outlets to reduce overloading

• Remove unsafe DIY electrical work

This improves tenant safety and reduces fire risk.

6. Poor DIY Electrical Work

Why It Fails

Non-compliant DIY alterations—such as incorrect wiring or unprotected connections—are frequently flagged in an EICR test report.

How to Fix It

• Have a qualified electrician inspect and correct all DIY work

• Ensure all electrical modifications meet current regulations

Professional repairs are essential for compliance.

7. Inadequate Lighting Circuit Safety

Why It Fails

Issues such as exposed wiring, no earth connection, or damaged fittings can lead to failure.

How to Fix It

• Replace unsafe light fittings

• Upgrade circuits where earthing is missing

• Repair damaged cables and switches

How to Avoid Failing an EICR Test Report

Landlords can reduce the risk of failure by:

• Scheduling regular electrical inspections

• Upgrading old electrical systems before testing

• Using qualified, registered electricians

• Addressing minor issues before they become serious hazards

Final Thoughts

Failing an EICR test report doesn’t have to be stressful or expensive. Most failures in rental properties are due to common, well-known issues that can be fixed quickly when identified early. By understanding these common faults and taking proactive steps, landlords can ensure electrical safety, protect tenants, and stay compliant with legal requirements.

If you’re preparing for an EICR inspection or need help addressing a failed report, consulting a qualified electrician is the safest and smartest next step.
