EICR vs Electrical Installation Certificate

A new consumer unit may look neat, modern and reassuring, but the paperwork issued afterwards matters just as much as the installation itself. The question of EICR vs electrical installation certificate often causes confusion because both documents relate to electrical safety, yet they answer two very different questions: has existing wiring been found safe to continue using, or has new electrical work been installed and tested correctly?

Knowing which certificate to ask for helps homeowners, landlords and business owners keep proper records, meet their responsibilities and avoid paying for the wrong type of visit.

EICR vs electrical installation certificate: the key difference

An Electrical Installation Condition Report, usually shortened to EICR, is a report on the condition of an existing fixed electrical installation. It is an inspection and testing exercise. An electrician checks the wiring, consumer unit, earthing, protective devices, sockets, switches and other fixed parts of the installation for deterioration, damage, defects or signs that it no longer meets safety requirements.

An Electrical Installation Certificate, or EIC, is issued for new electrical installation work or an addition or alteration to an existing installation. It confirms that the work has been designed, installed, inspected and tested in line with BS 7671, the IET Wiring Regulations, at the time it was completed.

Put simply, an EICR looks at what is already there. An EIC records newly completed work.

That distinction matters. An EICR cannot replace the completion certificate for a full rewire, and an EIC for a new installation does not guarantee that all older circuits elsewhere in a property remain in good condition.

What an EICR tells you

An EICR is sometimes referred to as a landlord electrical safety certificate, although it is useful well beyond rented homes. It provides a professional assessment of whether the electrical installation is satisfactory for continued use.

During an inspection, the electrician will carry out visual checks and electrical tests. This may include checking the consumer unit, circuit protection, earthing and bonding, polarity, insulation resistance and the operation of RCD protection. Access is required to relevant areas, and there may be short periods where circuits need to be switched off for testing.

The report will normally be marked either Satisfactory or Unsatisfactory. If issues are found, they are coded according to their severity. A C1 observation indicates danger is present and urgent action is needed. C2 means potentially dangerous work requires attention, while FI means further investigation is needed without delay. C3 observations are improvements recommended rather than items that automatically make the report unsatisfactory.

For landlords in England, an EICR is a legal requirement for rented properties at least every five years, or sooner if the report recommends a shorter interval. Any remedial work identified as necessary must also be completed within the required timescale. Homeowners are not generally subject to the same legal duty, but an EICR is a sensible precaution when buying a property, moving into an older home, planning major alterations or simply lacking confidence in the state of the wiring.

Commercial premises also need regular inspection, with the appropriate interval depending on the type of building, its use, the environment and the level of risk. A busy workshop, for example, may need more frequent attention than a low-risk office.

What an Electrical Installation Certificate proves

An Electrical Installation Certificate is normally issued after substantial electrical work. Examples include a full or partial rewire, a replacement consumer unit, the installation of new circuits, an extension with significant new wiring, or major electrical work in a commercial premises.

The certificate identifies the work completed, the person responsible for design, construction and inspection and testing, plus the test results for the new or altered circuits. It should clearly state any limitations or departures from the regulations. This creates an essential record for the owner and for anyone carrying out future work.

Where relevant domestic work is carried out, such as certain work involving a replacement consumer unit or new circuits, Building Regulations notification may also apply. A properly registered electrician can arrange notification where required, and the property owner should retain the resulting documentation with the EIC.

An EIC should be issued when the work is completed, not weeks or months later as an afterthought. If an electrician has undertaken notifiable or significant work and cannot provide appropriate certification, it is reasonable to ask why before making final payment.

What about a Minor Electrical Installation Works Certificate?

Not every small job needs a full EIC. For additions or alterations that do not include a new circuit, a Minor Electrical Installation Works Certificate may be the correct document. This could apply to work such as adding a socket spur, moving a light fitting or installing an extra point on an existing suitable circuit.

The right certificate depends on the scope of the work and the condition of the existing circuit. A qualified electrician should explain what paperwork will be issued before work begins. Verbal reassurance is useful, but formal certification is what provides a lasting compliance record.

When you need an EICR, an EIC, or both

The two documents can be needed at different stages of the same project. If you are buying an older house in Norfolk or Suffolk, an EICR before exchange can reveal concerns with ageing wiring, inadequate earthing or an outdated consumer unit. If the inspection leads to a rewire, the completed rewire should then be supported by an EIC.

Similarly, a landlord might receive an unsatisfactory EICR showing that a consumer unit needs replacement. Once the replacement and any remedial work have been completed, the installer should issue certification for that new work. Depending on the repairs undertaken and the original report, a further inspection or written confirmation may be needed to demonstrate that the points making the EICR unsatisfactory have been addressed.

For a straightforward new EV charger installation, the electrician will assess the property’s supply, earthing arrangement and protective devices before installation. The completed work should be certified, but this does not necessarily mean the property needs a whole-installation EICR at the same time. It depends on the findings, the age and condition of the installation, and whether there are signs that wider testing is sensible.

Do not confuse fixed wiring with appliance testing

An EICR covers fixed electrical installations. This includes items such as fixed wiring, consumer units, sockets, switches, light fittings and hard-wired equipment. It does not certify portable appliances such as kettles, computers, extension leads or plug-in heaters.

Portable Appliance Testing, often called PAT testing, is a separate process. A property may need both an EICR for the installation and appropriate checks on portable equipment, particularly in a workplace or furnished rental. They serve different purposes and neither should be presented as a substitute for the other.

Choosing the right electrician and keeping records

Electrical certificates are only as dependable as the inspection and testing behind them. Choose a competent, properly registered electrician who is prepared to explain the work in plain English, provide a clear quotation and give you the completed paperwork. Be wary of anyone offering a certificate without a proper inspection, or quoting a fixed price without asking basic questions about the property and the work required.

Keep EICRs, EICs, minor works certificates and Building Regulations paperwork together. They can be valuable when selling a property, responding to a tenant query, planning an extension or asking another electrician to work safely on the installation. They also make it easier to track recommended inspection dates and identify which circuits have been altered over time.

At Eclipse Electrical Solutions LTD, inspection, testing and installation work is approached with the same care: clear advice before work starts, professional testing when it is complete and the correct certification for the job.

If you are unsure which document applies, start with the reason you are arranging electrical work. A concern about the condition of existing wiring calls for an EICR; a completed new installation calls for an EIC. Asking that one question early can prevent uncertainty later and give you a safer, better-documented property.
