EICR Versus Electrical Installation Certificate

A completed refurbishment, a new consumer unit or a request from a letting agent can all prompt the same question: do you need an EICR or an electrical installation certificate? Understanding EICR versus electrical installation certificate is essential because they record different stages of electrical safety. One confirms new work has been installed and tested correctly. The Other assesses the condition of an existing installation over time.

For landlords and property managers, using the wrong document can create avoidable compliance gaps. A certificate for recently completed work is valuable, but it does not automatically prove the whole property has passed its required periodic inspection.

EICR versus electrical installation certificate: the key difference

An Electrical Installation Condition Report, usually called an EICR, is a report on the condition and safety of the electrical installation already in place. A qualified electrician inspects and tests circuits, protective devices, earthing and other relevant parts of the system to identify deterioration, damage, defects or signs of unsafe previous work.

An Electrical Installation Certificate, or EIC, is issued when electrical installation work has been completed. It confirms that a new installation, or a significant addition or alteration, has been designed, installed, inspected and tested in line with the relevant requirements at the time of the work.

Put simply, an EIC looks at work just completed. An EICR looks at whether an existing installation remains safe for continued use.

Both documents matter, but they cannot be used interchangeably. A landlord may hold an EIC for a new consumer unit, for example, while still requiring an EICR for the property under the relevant private rented sector rules.

What an EICR checks

An EICR is a structured inspection rather than a visual walk-through. The electrician will normally test a representative or appropriate range of circuits and assess the installation against the current edition of the wiring regulations, while recognising that older installations do not need to meet every modern standard simply because standards have changed.

The focus is safety. The report may identify damaged accessories, inadequate earthing or bonding, overloaded circuits, unsuitable consumer unit arrangements, signs of overheating, incorrect protective devices or defects caused by wear and alteration over time. Testing can require brief interruptions to the electrical supply, so it is sensible to plan access with tenants, staff or occupants in advance.

Observations are coded to help the responsible person understand priority. C1 means danger is present and urgent action is required. C2 means potentially dangerous and requires remedial work. FI means further investigation is needed without delay. C3 is an improvement recommendation and does not, on its own, make a report unsatisfactory.

Where C1, C2 or FI observations are recorded, the report will generally be unsatisfactory until the required remedial work or investigation has been completed. Keep the EICR, any remedial certificates and written confirmation of completion together. They form a clear compliance record if a tenant, managing agent, insurer or local authority asks for evidence.

When an electrical installation certificate is issued

An electrical installation certificate is generally issued after new electrical installation work or a significant alteration. Typical examples include a full or partial rewire, a new consumer unit, a new circuit for an electric shower, an outbuilding supply, or substantial electrical work completed as part of a conversion or refurbishment.

The certificate records details such as the installation address, the work undertaken, the person responsible for design, construction and inspection, test results, and any departures from the regulations. It should be completed by a competent electrician who has carried out, or properly supervised, the relevant work and testing.

For smaller alterations, such as adding or modifying an existing circuit, a Minor Electrical Installation Works Certificate may be appropriate instead of a full EIC. This is still a useful document and should be retained with the property’s electrical records. The exact certificate depends on the scope of the work, not simply the value of the job.

Some work is also subject to Building Regulations notification requirements. Your electrician should explain whether this applies and provide the relevant paperwork. Do not assume an invoice, a verbal assurance or a photograph of a new consumer unit is an acceptable substitute for certification.

Which document do landlords need?

In England, private landlords must ensure the electrical installation in a rented property is inspected and tested at intervals of no more than five years by a qualified and competent person. The EICR is the document used to demonstrate this inspection.

The landlord must provide a copy of the report to existing tenants within 28 days of the inspection and to new tenants before they occupy the property. If requested, a local authority must receive a copy within seven days. The report should also be provided to the next electrician carrying out the inspection within 28 days.

If the EICR identifies remedial work, the landlord must arrange it within 28 days, or sooner if the report specifies a shorter period. Written confirmation that the work has been completed or that further investigation has established the installation is safe must then be supplied to tenants and the local authority where required.

An electrical installation certificate does not remove these obligations. Even where major work has been completed and certified, the landlord should check the EICR date and any recommended next inspection date for the wider installation. The safest approach is to treat the EIC as evidence of the completed job and the EICR as the ongoing condition report for the property as a whole.

What about commercial and managed properties?

Commercial premises do not usually operate under the same fixed five-year private rental requirement. However, duty holders still have responsibilities to maintain electrical systems safely, including under the Electricity at Work Regulations. An EICR is commonly used to support this duty, with inspection frequency based on the type of premises, how the installation is used, its age, environmental conditions and previous report findings.

A busy office, workshop, communal area or retail unit may need a different inspection plan from a low-use residential property. Wet, dusty, externally exposed or high-traffic environments can justify more frequent attention. Property managers should avoid relying on a standard interval without considering the actual risks on site.

For portfolios, a central record of EICRs, EICs, minor works certificates, remedial actions and expiry dates makes handovers and inspections far easier. It also prevents a common problem: electrical paperwork being held by a previous agent, contractor or owner while the current responsible person believes the property is covered.

Common mistakes that cause compliance problems

The first mistake is treating a recent certificate as proof that every circuit in the property has been inspected. If an electrician has installed a new circuit, their EIC may relate only to that work. Older circuits, accessories and protective measures may still need assessment through an EICR.

The second is delaying remedial work after an unsatisfactory report. A C2 or FI observation should be dealt with promptly, not left until a planned refurbishment or the next void period. Where a property is occupied, clear communication and carefully arranged access can reduce disruption while keeping the tenant safe.

The third is failing to retain documents. Certification should stay with the property file, even when ownership, management or tenancy changes. Scanned copies are practical, but make sure they are complete and legible, including schedules, test results and signatures.

Finally, do not confuse electrical certification with an electrical safety check of portable appliances. Portable Appliance Testing is a separate process and does not replace an EICR. Likewise, an EICR does not cover every item plugged into the installation.

Planning electrical work without unnecessary disruption

The most efficient time to review electrical compliance is before a tenancy starts, during a void, or when refurbishment work is already scheduled. This allows access to be coordinated with decorating, cleaning, fire safety works and repairs, rather than creating several separate visits.

That said, safety work should not wait for the perfect diary slot. If an inspection identifies an immediate concern, secure the installation and arrange the required remedial work first. For landlords and managing agents across East Sussex, Action Property Group can help coordinate electrical testing, remedial works and wider property preparation so the handover process stays clear and manageable.

Keep the distinction straightforward: request an EIC or minor works certificate when electrical work is completed, and arrange an EICR when the condition of the installation needs to be assessed. With the right paperwork filed and any findings acted on promptly, a property is better prepared for occupation, inspection and the next handover.
