Common questions

What does an unsatisfactory EICR look like?

An unsatisfactory EICR has at least one observation coded C1 (danger present), C2 (potentially dangerous) or FI (further investigation required). Our sample shows two C2 codes: an unfused 100 A isolator and a 16 mm² sub-main that is not protected for the 100 A supply.

Can a satisfactory EICR still list faults?

Yes. A satisfactory report can contain C3 'improvement recommended' observations, such as Type AC RCDs or no surge protection. C3s do not make a report unsatisfactory, but they are worth planning in.

How long is an EICR valid for?

The inspector recommends the next inspection date. For private rentals the legal maximum is 5 years; for owner-occupied homes 10 years is typical.

Why do the reports say 25% sampling?

That figure records the extent stated on these particular reports, not a universal permitted minimum. A previous EICR can inform the inspector's sampling plan but does not automatically permit 25% testing. If a sample reveals defects or deterioration, the inspector should extend the relevant checks to establish their extent. BS 7671 does not prescribe fixed percentage increases; see Section D for the recorded scope and limitations.
