EICRs explained: scope, findings and next steps

Book an appropriate inspection

Choose someone competent in inspection and testing for your type of installation. Registration can help demonstrate this, but a general installation registration alone is not enough. Agree the extent, access, limitations and expected power interruptions. Share previous reports and certificates.

• Ask whether outbuildings, shared areas and specialist equipment need separate arrangements.
• An EICR concerns existing installation condition; it is different from certification of newly completed work and from appliance testing.

Read the findings, not just the headline

C1 means danger is present and needs immediate action; C2 means potentially dangerous and needs urgent repair. C3 recommends improvement. Under Electrical Safety First's current 2026 guidance, FI advises further investigation of an unresolved possible safety issue; FI alone does not automatically determine an unsatisfactory outcome. Ask the inspector to explain what must happen and how soon.

• C1 or C2 makes the overall assessment unsatisfactory. C3 alone can be satisfactory.
• A satisfactory outcome does not remove the need to follow up FI or newly emerging faults. Never attempt the investigation yourself.

Keep an action record

For rented homes covered by England's regulations, inspections are required at least every five years, or sooner where required. Necessary remedial work or investigation must be completed within 28 days or a shorter period specified in the report; immediate hazards cannot wait. Keep the report with written confirmation of follow-up work and arrange required tenant and council copies. Owner-occupiers should agree their next inspection date with the inspector rather than assume the rental interval applies.
