EICR Limitations Explained
EICR limitations are the parts of an installation not inspected or tested, and why — recorded on the report so the result is transparent and honest.
Limitations on an EICR record the parts of an installation that were not fully inspected or tested, together with the reason. They are a normal and important part of an honest report — they tell the duty holder precisely what was assessed and what was not.
Why limitations exist
An installation cannot always be tested in full. Common, legitimate reasons include:
- Operational constraints — circuits serving critical equipment that cannot be switched off during the visit.
- Access — accessories or cabling concealed behind fixed structures or stored goods.
- Agreed sampling — on large installations, testing a representative sample rather than every circuit.
Two types of limitation
- Agreed limitations are those the client and inspector decide before work begins (for example "no isolation of the server room supply").
- Operational limitations are those the inspector encounters on site and records as found.
Both are noted on the report, with the extent and reasons stated.
Why they must be recorded
A report that hides its gaps is misleading. By recording limitations, the EICR:
- keeps the overall result meaningful — a "Satisfactory" outcome only covers what was actually assessed;
- lets the duty holder arrange a follow-up to close the gaps; and
- protects everyone by making the scope of the inspection explicit.
When comparing quotes, be wary of an unusually cheap EICR — it may rely on excessive limitations that leave much of the installation unassessed.
Frequently asked questions
Are limitations a sign of a poor EICR?
Not necessarily. Some limitations are unavoidable — for example circuits that cannot be isolated in a live commercial environment. What matters is that every limitation is clearly recorded and agreed, so you know exactly what was and was not assessed.

Code explanation
EICR C1 Code: Danger Present
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.

EICR C2 Code: Potentially Dangerous
A C2 on an EICR means potentially dangerous — no immediate danger, but a fault could make it dangerous. It requires urgent remedial action and fails the report.

Difference Between C2 and C3 on an EICR
C2 is potentially dangerous and fails an EICR, requiring urgent remedial work; C3 is a non-urgent improvement recommendation that keeps the report Satisfactory.
