Difference Between EIC and EICR: A Practical UK Guide

What is an Electrical Installation Certificate?

An Electrical Installation Certificate, usually shortened to EIC, is used for defined new electrical installation work where an EIC is the appropriate BS 7671 certification document.

Examples can include a new electrical installation, the introduction of a new circuit, a full rewire or other qualifying installation work. The exact certificate depends on the work actually carried out rather than simply on the size or cost of the job.

An EIC records the extent of the work covered by the certificate together with relevant information about design, construction, inspection and testing. It also includes schedules relating to inspections and test results.

This means the scope is important. An EIC for one newly installed circuit does not automatically certify unrelated existing circuits elsewhere in the property.

What is an Electrical Installation Condition Report?

An Electrical Installation Condition Report, or EICR, is used to assess and report on the condition of an existing electrical installation following periodic inspection and testing.

The inspector considers the fixed electrical installation within the agreed extent and limitations of the inspection. The report records inspection findings, test results, observations and an overall assessment of the installation's condition at the time of inspection.

An EICR therefore does not certify the original design and construction of historic electrical work. Its purpose is to assess the installation that exists now.

EIC vs EICR: what is the main difference?

The main difference is the purpose of the document. An EIC is primarily about defined electrical installation work that has been completed. An EICR is primarily about the current condition of an existing electrical installation.

What about a Minor Electrical Installation Works Certificate?

Not every piece of electrical work requires an EIC. A Minor Electrical Installation Works Certificate, often shortened to Minor Works or MEIWC, can be appropriate for certain additions or alterations to an existing circuit where the work does not introduce a new circuit.

This distinction is useful because people sometimes assume the choice is always EIC or EICR. In practice, there are three different questions:

• Is this defined new installation work requiring an EIC?
• Is this a qualifying addition or alteration to an existing circuit for which Minor Works certification is appropriate?
• Is the purpose to assess the condition of an existing installation, in which case an EICR may be appropriate?

The electrician should select the certification that matches the actual scope of the electrical work.

Can an EIC replace an EICR?

Not as a general like-for-like replacement. An EIC and an EICR have different purposes, so an EIC for a piece of new work should not automatically be treated as evidence of the condition of every existing circuit in a property.

There is, however, an important landlord exception in England. Current government guidance states that where rented premises are newly built or have been completely rewired, they should have an EIC. Where the landlord has complied with the applicable duties, that EIC can be supplied to the tenant and local council where required, without another inspection being needed for five years from the date of the EIC.

Is an EIC the same as a Part P or Building Regulations certificate?

No. BS 7671 electrical certification and Building Regulations documentation should be kept separate.

An EIC records the electrical installation work and its inspection and testing. In England, Approved Document P provides statutory guidance on electrical safety in dwellings and explains when notification of electrical work is required.

Depending on the work and the compliance route used, a property owner may therefore receive an EIC or other appropriate electrical certificate as well as separate Building Regulations notification or compliance documentation.

The two records may relate to the same project, but one should not automatically be described as the other.

What if the Electrical Installation Certificate is missing?

If electrical work appears to have required certification but the EIC cannot be found, start by checking the original installer's records, property files and any available Building Regulations documentation.

A standard EIC should not simply be treated as replacement paperwork for unknown historic work. The document records defined responsibilities and the inspection and testing associated with the work it certifies, so the appropriate route depends on what was installed, who carried out the work and what records remain available.

An EICR may be useful if the objective is to assess the present condition of an existing electrical installation, but it does not recreate the original EIC or transfer responsibility for historic work to the person carrying out the condition report.

Which electrical document do you need?

Start with the reason the document is needed rather than searching for a generic “electrical certificate”.

• New electrical installation or new circuit: an EIC may be required for the completed work.
• Certain additions or alterations to an existing circuit: a Minor Electrical Installation Works Certificate may be appropriate.
• Condition of existing fixed electrics: an EICR is normally the relevant report.
• Missing historic paperwork: the correct route depends on what work was carried out and what evidence still exists.
• Building Regulations evidence: check the relevant notification or compliance documentation separately from the BS 7671 electrical certificate.

In mixed situations, more than one document can legitimately exist for the same property. An older installation may have an EICR covering its present condition while later new circuits have their own EICs or Minor Works certificates.
