EICR Testing for Landlords: How Often Do You Need It? (2026 Update)

Key Takeaways

• EICR required every 5 years for all private rental properties in England (since June 2020)
• Must provide copy to new tenants before they move in, and within 28 days to existing tenants
• Unsatisfactory reports (containing C1, C2, or F1 codes) must be remediated within 28 days
• Fines up to £30,000 per breach for non-compliance
• You do not need a full new EICR after remedial work — a Minor Works Certificate combined with the original report is sufficient
• Visual inspections between tenancies are strongly recommended as best practice

Electricity is silent, invisible, and potentially lethal. In 2020/21, electrical faults caused an estimated 14,800 domestic fires in England alone — roughly 40 per day. Unlike a gas leak, which you might smell, a faulty wiring connection behind a wall gives no warning before it ignites.

This is why the UK government introduced mandatory electrical safety checks for all private rental properties in England in 2020. The Electrical Installation Condition Report (EICR) is now as fundamental to letting a property as the Gas Safety Certificate (CP12). But the 5-year inspection cycle, the complex coding system, and the differences between an EICR and other electrical certifications cause significant confusion among landlords.

This guide is part of our complete Landlord Compliance hub.

What Is an EICR?

An Electrical Installation Condition Report is a detailed inspection and testing of the fixed electrical installation in your property. This means everything permanently wired in: the consumer unit (fuse box), all wiring behind walls, sockets, switches, light fittings, ceiling roses, and the main earth bonding.

Think of it as an MOT for your property's electrical system. Just as a car MOT doesn't check the engine oil, an EICR doesn't check portable appliances — kettles, toasters, TVs, and lamps are covered by PAT testing (a separate process). The EICR specifically targets the built-in wiring that a tenant cannot see or inspect themselves.

What makes the EICR important for landlords specifically: If a tenant is electrocuted or a fire is caused by faulty wiring that you, as landlord, were responsible for maintaining, you are personally liable. An up-to-date satisfactory EICR is your primary evidence that the electrical installation was safe at the time of inspection.

The Legal Framework: The 5-Year Rule

Under The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, all private landlords must:

1. Ensure the electrical installations in their rental properties are inspected and tested by a qualified person at intervals of no more than 5 years
2. Provide a copy of the EICR to new tenants before they occupy the property
3. Provide a copy to existing tenants within 28 days of the inspection
4. Supply a copy to the local housing authority within 7 days if requested

When might you need one sooner than 5 years?

• If the previous electrician recommended an earlier re-inspection date (common with older installations)
• If you've had significant electrical work done (a new consumer unit, rewire, or extension) — the new work will have its own Electrical Installation Certificate, but the rest of the installation still needs the EICR on its original schedule
• Between tenancies: while not legally required if the current EICR is valid, a visual condition check between tenants is best practice and may be required by your insurer

What Happens During an EICR Inspection?

The inspection involves both visual checks and physical electrical testing, and the electrician will need access to every room in the property plus the consumer unit and meter.

Visual Inspection

The electrician walks through every room checking:

• Socket and switch faceplates for damage, discolouration (indicating heat), or loose mounting
• Light fittings for secure installation and correct rating
• Consumer unit (fuse box) for correct labelling, appropriate-rating MCBs (circuit breakers), and signs of overheating
• Visible wiring for damage, incorrect routing, or non-compliant alterations
• Earth bonding connections to gas and water pipework

Dead Testing (Power Off)

With the electricity turned off at the consumer unit, the electrician tests:

• Continuity of protective conductors: Confirming that all earth wires provide a complete, unbroken path back to the consumer unit
• Insulation resistance: Measuring the resistance between live conductors and earth. Low insulation resistance indicates degraded or damaged cable insulation — a fire and shock risk
• Polarity: Confirming that live and neutral connections are correctly wired at every socket and switch. Reversed polarity is dangerous and not detectable by normal use

Live Testing (Power On)

With the electricity restored:

• Earth fault loop impedance (Ze and Zs): Measures how quickly a fault would cause the protective device (MCB or RCD) to trip. If the impedance is too high, the circuit breaker might not trip fast enough to prevent electrocution
• RCD testing: Each RCD (Residual Current Device) is tested at multiple current levels to confirm it trips within the required time (typically 300ms at rated current, 40ms at 5x rated current)
• Prospective fault current (PFC): Measures the maximum fault current that could flow in the event of a dead short — the consumer unit's protective devices must be rated to safely interrupt this current

Duration and Disruption

• A typical EICR takes 2–4 hours depending on property size and the number of circuits
• Power will be switched off for a significant portion of the dead testing phase — typically 30–90 minutes
• Tenants should be warned: no WiFi router, no fridge/freezer, no medical equipment that requires power during this period
• The electrician needs access to every room, every socket, every light switch, and the consumer unit — ensure nothing is blocked

Understanding EICR Observation Codes

This is where confusion is most common. The coding system determines whether your EICR is "Satisfactory" or "Unsatisfactory" — and each code carries different obligations.

Code C1: Danger Present

A C1 means someone could be injured right now. Examples include exposed live conductors, a socket with no earth connection, or a consumer unit with signs of active arcing. The electrician will disconnect the affected circuit or make it safe before leaving the property. This cannot wait — it must be fixed immediately.

Code C2: Potentially Dangerous

A C2 means a fault exists that could cause injury under certain conditions. The most common C2 findings include:

• Missing or inadequate earth bonding to gas and water pipework
• No RCD protection on circuits that require it (bathrooms, outdoor sockets)
• Cables routed through areas where they're exposed to damage
• Consumer unit not meeting current fire enclosure standards

You have 28 days from the date of the report to arrange remedial work. After the work is completed, the electrician issues a Minor Works Certificate or Electrical Installation Certificate confirming the fault has been resolved.

Code C3: Improvement Recommended

A C3 is not a fail. It means the installation doesn't meet the latest edition of BS 7671 (the Wiring Regulations), but it was compliant when originally installed and is not currently unsafe. Common examples include:

• No RCD protection on lighting circuits (not required under older editions of the standard)
• Metal consumer unit that could be upgraded to a fire-rated plastic enclosure

You are not legally required to act on C3 observations, but addressing them during void periods between tenancies is good practice — it reduces the chance of a C2 or C1 appearing at the next inspection.

FI: Further Investigation Required

An FI means the electrician could not complete their assessment of a particular aspect of the installation without opening up a ceiling, lifting floorboards, or doing additional investigative work. FI observations are treated the same as C2 for compliance purposes — you have 28 days to investigate and resolve.

The pass/fail threshold: Your EICR is "Satisfactory" only if it contains zero C1, C2, or FI observations. Any one of these makes the report "Unsatisfactory" and triggers the 28-day remediation obligation.

The 28-Day Remediation Process

If your EICR comes back Unsatisfactory, the law requires you to:

1. Arrange remedial work by a qualified electrician within 28 days of the report date (or sooner if specified for C1 items)
2. Obtain written confirmation that the work is complete — this will be either an Electrical Installation Certificate (EIC) for major work or a Minor Works Certificate for smaller fixes
3. Provide copies of the completion certificate to your tenant within 28 days of the work being done
4. Provide copies to the local housing authority within 28 days if requested

Important: You do not need to commission an entirely new EICR after remedial work. The original Unsatisfactory report plus the remedial completion certificate together constitute proof of compliance. A new full EICR is only needed when the current one reaches its 5-year expiry.

EICR Costs in 2026

Prices vary by property size (number of circuits), location, and the complexity of the installation:

These prices cover the inspection and report only. Remedial work to resolve C1 or C2 observations is charged separately.

Finding a qualified electrician: The regulations require a "qualified and competent person." In practice, this means an electrician registered with one of the government-approved Competent Person Schemes:

• NICEIC (National Inspection Council for Electrical Installation Contracting)
• NAPIT (National Association of Professional Inspectors and Testers)
• ELECSA
• Part P registered electricians

Using a registered electrician is not just best practice — it's effectively a requirement, because an EICR issued by an unregistered individual may not be accepted by local authorities as valid.

Penalties for Non-Compliance

The Regulations give local housing authorities the power to:

• Issue a remediation notice requiring you to carry out the inspection or remedial works
• Arrange the work themselves and recover the costs from you, plus administrative charges
• Issue a financial penalty of up to £30,000 per breach

The £30,000 figure is a maximum. In practice, penalties for first-time non-compliance with no tenant harm typically range from £2,000–£10,000. However, repeated non-compliance or cases involving tenant injury attract penalties at the higher end.

An EICR-related prosecution can also invalidate your landlord insurance and undermine a Section 21 eviction notice — the same consequences that apply to Gas Safety Certificate non-compliance.

How to Prepare for an EICR Inspection

1. Clear access to the consumer unit — remove any items stored in front of or around the fuse box
2. Ensure all sockets and switches are accessible — move furniture away from walls where needed
3. Replace any broken socket/switch covers — cracked faceplates are a visual inspection failure and cost £2–£5 to replace
4. Replace blown light bulbs — the electrician needs to verify that each circuit functions; a dead bulb makes this impossible
5. Notify tenants — give at least 24 hours' written notice, warn them about the 1–2 hour power outage, and suggest they charge phones and laptops beforehand
6. Have previous EICR ready — the electrician can compare observations between inspections and identify deterioration trends

Landlord Compliance Overview

Conclusion

The EICR is a five-year obligation, which makes it easy to forget — especially if you acquired a property mid-cycle and don't have a clear record of when the last inspection occurred. If in doubt, book one now and establish a clean baseline.

The inspection itself is straightforward but disruptive (expect 2–4 hours with power off). Plan it during a void period if possible. And if the report comes back Unsatisfactory, act within the 28-day window — the cost of remedial work is almost always less than the cost of a £30,000 penalty notice.
