EICR: Frequently Asked Questions
Answers to the most common EICR questions — what it is, how often it's needed, what the codes mean, and what to do with an unsatisfactory report.
This page brings together the questions we are asked most often about EICRs. For detailed explanations, follow the links to the full guidance — each answer here points to the page that owns the topic so you always get the complete picture.
Start with the basics
If you are new to EICRs, begin with our pillar guide, What Is an EICR?, which explains what the report covers, the legislation and standards behind it, and how to read the result.
Frequency and validity
How often you need an EICR depends on the premises and its use — see How Often Is an EICR Required? for the common intervals and the reasons an inspector may recommend a shorter one.
The inspection itself
To understand what actually happens on the day — the visual inspection, dead and live testing, and reporting — read What Happens During an EICR?.
Cost
For a fair understanding of pricing without misleading headline figures, see What Affects the Cost of an EICR?.
The questions below answer the quick points directly. For anything more detailed, the guides above go further.
Frequently asked questions
What does EICR stand for?
EICR stands for Electrical Installation Condition Report — a formal report on the safety and condition of a fixed electrical installation, assessed against BS 7671.
How long is an EICR valid for?
An EICR is valid until the next inspection date recommended on the report — commonly up to 5 years, and up to 10 years for owner-occupied homes, but it can be shorter where the condition or use of the installation warrants it.
What makes an EICR unsatisfactory?
Any observation coded C1 (danger present), C2 (potentially dangerous) or FI (further investigation required) results in an Unsatisfactory outcome. A report containing only C3 observations remains Satisfactory.
What do C1, C2, C3 and FI mean?
C1 means danger is present and immediate action is required. C2 means potentially dangerous and urgent remedial action is required. C3 is an improvement recommendation. FI means further investigation is required without delay.
Do I have to fix C3 items?
No. C3 observations are recommendations for improvement and do not make a report unsatisfactory. Addressing them is good practice but not mandatory.
Is an EICR the same as PAT testing?
No. An EICR covers the fixed installation — wiring, boards and accessories. PAT (in-service inspection and testing) covers portable appliances that plug into that installation. They are complementary but separate.

A C1 on an EICR means danger is present and a risk of injury exists. It requires immediate action and always makes a report Unsatisfactory.

Difference Between C1 and C2 on an EICR
C1 means danger is present now and requires immediate action; C2 means potentially dangerous — safe now but a fault could make it dangerous. Both fail an EICR.
