What Is an EICR? The Ultimate Guide for Landlords (2026 UK Update)

If you’ve been told you need an EICR, or you’ve just had one done and don’t fully understand the results, you’re not alone.

Most landlords only deal with this every few years — so when it comes up, it can feel unclear, technical, and sometimes frustrating.

This guide breaks everything down in plain English. What an EICR actually is, what gets tested, why properties fail, and what you realistically need to do next.

What Is an EICR?

An Electrical Installation Condition Report (EICR) is a formal inspection carried out by a qualified electrician to assess the safety of your property’s electrical system.

It looks at wiring, the consumer unit (fuse board), earthing, bonding, and all fixed electrical components throughout the property.

The goal is simple — to confirm whether the installation is safe to continue using.

At the end, the report will be marked as either:

• Satisfactory (safe)
• Unsatisfactory (requires work)

Is an EICR a Legal Requirement?

For landlords in England, yes.

Under current regulations:

• Rental properties must have a valid EICR every 5 years
• This applies to new and existing tenancies
• You must provide a copy to tenants and local authorities if requested

Why an EICR Matters (Not Just a Tick-Box)

A lot of landlords assume an EICR is just paperwork. It’s not.

A proper inspection will identify:

• Fire risks
• Electric shock risks
• Faults that could cause circuits to fail
• Outdated protection that no longer meets current standards

In many cases, issues aren’t obvious until proper testing is carried out — especially in older properties. You can see real examples in this guide on why older homes fail EICRs.

What Does an EICR Test Actually Involve?

1. Visual Inspection

The electrician checks for obvious issues such as damaged accessories, signs of overheating, poor installation work, and unsafe enclosures.

2. Electrical Testing

This is where most faults are found.

Tests typically include:

• Continuity testing (ensuring circuits are correctly connected)
• Insulation resistance (checking cable condition)
• Earth fault loop impedance (Zs readings)
• RCD/RCBO disconnection times

RCD performance is one of the biggest causes of failure — especially where tripping times are incorrect or the wrong type is installed. You can read more about RCD fault finding and tripping issues.

What Do EICR Codes Mean?

Each issue found is given a classification code. If you’re unsure, see our full guide on EICR codes explained.

• C1 – Danger present (immediate action required)
• C2 – Potentially dangerous (urgent remedial work required)
• C3 – Improvement recommended
• FI – Further investigation required

If your report includes C1 or C2 observations, it will be classed as unsatisfactory.

Why Did My Property Fail When It Passed Before?

This is one of the most common frustrations landlords have.

Reasons include:

• Standards have tightened (18th Edition updates)
• Testing is more thorough than previous inspections
• Faults have developed over time

It’s also common for landlords to misunderstand terminology — especially with reports labelled differently. If you’ve seen variations, this guide explains the difference between EICR terms.

EICR vs EIC vs PAT Testing

These are often confused:

• EICR: Condition report of an existing installation
• EIC: Certificate for new electrical work
• PAT testing: Checks portable appliances

How Often Should an EICR Be Done?

• Landlords: Every 5 years (legal requirement)
• Homeowners: Every 5–10 years
• Commercial properties: Every 3–5 years
• Change of tenancy: Often recommended

How Much Does an EICR Cost?

Costs vary depending on the property:

• Small property: £100 – £180
• Larger properties: £150 – £250+
• Commercial: depends on size and complexity

The EICR itself only reports on the condition — any remedial work is quoted separately.

Final Thoughts

An EICR isn’t just a formality — it’s a proper safety check.

If your property passes, you’ve got peace of mind. If it fails, it’s an opportunity to fix issues before they become serious problems.

If you’ve received a report and aren’t sure what it means, it’s always worth getting it reviewed before committing to remedial work.
