What Is an EICR Certificate?

An EICR certificate, short for Electrical Installation Condition Report, is an official electrical safety inspection carried out by a qualified electrician. The purpose of an EICR is to assess the condition, safety, and compliance of a property's electrical installation.

During the inspection, electricians test circuits, fuse boards, wiring systems, sockets, lighting, earthing, bonding, and fixed electrical components to identify faults, deterioration, overloading risks, or anything that could present a danger.

An EICR is essential for landlords, businesses, commercial premises, and homeowners who want to ensure their electrical systems remain safe, compliant, and functioning properly.

At AZ Electrical, we carry out professional EICR inspections across London for residential, commercial, and landlord properties, helping clients remain compliant while identifying issues before they become serious safety hazards.

What Does an EICR Check Include?

An Electrical Installation Condition Report involves a detailed inspection and testing process designed to assess the overall condition of the electrical installation.

This includes:

• Consumer unit (fuse box) inspection

• Circuit testing and verification

• Socket and switch testing

• Lighting circuit checks

• Earthing and bonding verification

• Inspection of electrical accessories

• Identification of overloaded circuits

• Detection of fire and electric shock risks

• Testing of RCD protection devices

• Checking compliance with current UK wiring regulations

The inspection helps identify both immediate dangers and potential future issues that may worsen over time.

Why Is an EICR Important?

Electrical systems naturally deteriorate with age, usage, heat, moisture, poor workmanship, and DIY alterations. Faulty electrical systems are among the leading causes of electrical fires in UK properties.

An EICR helps detect problems early before they lead to:

• Electric shocks

• Electrical fires

• Power failures

• Overloaded circuits

• Damaged appliances

• Insurance complications

• Legal compliance issues for landlords

Regular inspections provide peace of mind while ensuring the property remains safe for occupants, staff, tenants, or visitors.

Is an EICR a Legal Requirement?

For Landlords

Yes. In England, landlords are legally required to have the electrical installation inspected and tested at least every five years by a qualified electrician.

The regulations apply to:

• Private rented properties

• HMOs (Houses in Multiple Occupation)

• Apartments and flats

• Single-let residential properties

Landlords must provide tenants with a copy of the EICR and complete any remedial works identified within the required timescales.

AZ Electrical also provides landlord electrical compliance services throughout London.

For Commercial Properties

Commercial premises also require regular electrical inspections under health and safety legislation and workplace regulations.

This applies to:

• Restaurants

• Retail units

• Offices

• Warehouses

• Schools

• Industrial buildings

• Hospitality venues

Businesses have a duty of care to ensure electrical systems remain safe for employees and the public.

How Often Should an EICR Be Carried Out?

The recommended inspection frequency depends on the property type and usage.

Typical EICR Inspection Intervals

• Domestic owner-occupied homes – every 10 years

• Rental properties – every 5 years

• Commercial premises – every 5 years or change of occupancy

• Industrial environments – every 3 years

• Restaurants and high-use premises – often more frequently

Older properties, heavily used electrical systems, or buildings with previous electrical issues may require more regular inspections.

What Do EICR Codes Mean?

After testing is complete, observations are categorised using official classification codes.

Common EICR Observation Codes

• C1: Danger present – immediate risk requiring urgent action

• C2: Potentially dangerous – remedial work required

• C3: Improvement recommended

• FI: Further investigation required

If the report contains C1 or C2 observations, the installation will usually be classified as unsatisfactory until repairs are completed.

Common Reasons Properties Fail an EICR

Many London properties, particularly older homes and converted flats, contain outdated or unsafe electrical installations.

Typical EICR Failures Include:

• Old fuse boxes without RCD protection

• Damaged wiring insulation

• Overloaded circuits

• Poor earthing or bonding

• Unsafe DIY electrical work

• Broken sockets or switches

• Incorrect cable installations

• Fire risks near electrical equipment

Experienced London electricians quickly identify these issues and provide clear guidance on any required remedial work.

What Happens If You Fail an EICR?

Failing an EICR does not necessarily mean the property is dangerous overall, but it does indicate that certain issues require attention.

Once the inspection is complete, the electrician will issue:

• The full EICR report

• A breakdown of faults found

• Observation codes

• Recommendations for remedial works

• A quote for corrective work if required

After repairs are completed, a satisfactory certificate can then be issued.

How Long Does an EICR Take?

The duration depends on the size and complexity of the property.

Typical EICR Timeframes

• 1-bedroom flat – 2 to 4 hours

• 3-bedroom house – 4 to 6 hours

• Commercial premises – varies significantly

• Restaurants and offices – often full-day inspections

Testing involves isolating circuits temporarily, so short power interruptions may occur during the inspection process.

Can You Sell a House Without an EICR?

Yes, an EICR is not currently mandatory for selling a property in England. However, many buyers request one before purchase as part of due diligence.

An up-to-date EICR can:

• Increase buyer confidence

• Reduce delays during conveyancing

• Highlight electrical upgrades already completed

• Help prevent renegotiation issues

Why Professional EICR Testing Matters

An EICR should only be carried out by a qualified and experienced electrician with the correct testing equipment and knowledge of current wiring regulations.

Poor-quality inspections can miss serious faults or produce inaccurate reports, creating legal and safety risks.

AZ Electrical provides professional electrical inspection and testing services throughout London with a strong focus on safety, compliance, transparency, and long-term reliability.

Frequently Asked Questions

How much does an EICR cost in London?

The cost depends on the property's size, the number of circuits, and the building type. Flats are generally cheaper than large houses or commercial premises.

Do I need an EICR every five years?

Rental properties are legally required to be tested every 5 years. Commercial premises may also require regular inspections depending on usage.

Can I do an EICR myself?

No. EICR inspections must be completed by a qualified electrician with appropriate testing equipment and certification knowledge.

Will the power need to be turned off during an EICR?

Yes. Certain circuits need to be isolated temporarily during testing to complete the inspection safely.

What happens after an EICR?

You receive the full Electrical Installation Condition Report, which outlines the condition of the installation, observations, and any recommended remedial work.
