What an EICR is

Electrical Installation Condition Report, in plain English.

An EICR is a health check on the fixed wiring of a building: the board, the circuits, the sockets, the lighting and the earthing. It does not cover appliances you plug in. It tells you whether the installation is safe to keep using, and if it is not, exactly what needs fixing.

⭐ It ends in one of two results: satisfactory or unsatisfactory. Anything coded C1, C2 or FI makes it unsatisfactory. C3 items on their own do not.

What the codes mean

So you know what has to be paid for, and what can wait.

C1: danger present

Someone could be hurt now. We make it safe before we leave, usually by isolating the circuit, and tell you straight away.

C2: potentially dangerous

Not dangerous this minute, but could become so. Has to be put right for the report to be satisfactory.

C3: improvement recommended

Does not meet today's standard, but is not unsafe. Not a fail. Something to plan for.

FI: further investigation

Something we could not fully check on the day. It needs looking at before the report can be satisfactory.

How the job works

From booking to the report in your hand.

Book a time

We arrange access with you, or with your tenant or site manager.

Inspect and test

Each circuit is inspected and tested. The power goes off in stages, so we tell you when to expect it.

Report

The written EICR, with every code explained in plain English, not just listed.

Put right, if needed

Any remedial work is quoted separately so you can decide. Once it is done, you get the paperwork to show it.

How the certificates work

Three different documents, and which one you get when.

EICR

The condition report on an existing installation. What a landlord, a letting agent or an insurer asks for.

Electrical Installation Certificate

Issued for new work: a rewire, a new circuit, a new consumer unit, a new build.

Minor Works Certificate

Issued for small changes to an existing circuit, such as an added socket or light.

How often you need one

Guidance, not a substitute for the regulations themselves.

Rented homes in Northern Ireland

At least every five years, by law. See our landlord page for the dates.

Shops, offices and other business premises

Usually every five years, and more often for some uses. See commercial testing.

Your own home

Recommended every ten years, and when you buy a house.

Common questions

Will the power be off all day?

No. It goes off circuit by circuit while each is tested, so you are never without power for long.

What if the report is unsatisfactory?

We show you exactly which items cause it, quote the remedial work, and give you the paperwork once it is done.

Is a C3 a fail?

No. A C3 is a recommendation. The report can still be satisfactory.
