Electrical Condition Report (EICR)

Since 1 April 2021, private landlords in England have been legally required to have an EICR carried out on every rental property at least every five years, or on each change of tenancy. Non-compliance carries fines of up to ยฃ30,000. The report must be issued by a contractor approved by NICEIC or NAPIT โ€” an unaccredited electrician cannot issue a report that satisfies the legal requirement. GEM 24/7 holds both NICEIC and NAPIT approval, and issues EICRs on the same day as the inspection.

Understanding your EICR result codes

Code Meaning What it means for your property
C1 Danger present Immediate danger to the occupants. Remedial work must be completed before the property can be safely occupied. A satisfactory EICR cannot be issued until C1 items are rectified.
C2 Potentially dangerous Poses a risk but not an immediate danger. Urgent remedial work required, usually within 28 days. A satisfactory EICR cannot be issued until C2 items are rectified.
C3 Improvement recommended Not unsafe, but improvement is advised. A C3 code does not prevent a satisfactory EICR from being issued. Your engineer will explain the specific recommendation.
FI Further investigation required More investigation is needed before a full assessment can be completed. The engineer will advise on the scope and cost of any investigation work.

A satisfactory EICR means no C1 or C2 codes were found. A report with only C3 codes can still be issued as satisfactory. Your GEM 24/7 engineer will explain any codes found and advise on the cost and urgency of any remedial work before you commit to anything.

PAT Testing

Portable appliance testing checks that electrical appliances are safe for continued use. It's required annually for furnished rental properties and commercial premises. A PAT testing certificate is issued on the same day as the test, covering every appliance tested. GEM 24/7 carries out PAT testing across central London with no call-out fee.

What NICEIC and NAPIT approved actually means

NICEIC and NAPIT are the two government-recognised schemes for approving competent electrical contractors in the UK. To hold approval from either scheme, a contractor must demonstrate technical competence, maintain appropriate insurance, and submit to regular inspection.

GEM 24/7 holds both.

In practice, this matters because only contractors approved by NICEIC or NAPIT at the approved contractor level can issue a legally valid Electrical Condition Report (EICR). A report issued by an unapproved contractor has no legal standing. Landlords who accept an EICR from an unaccredited electrician remain non-compliant, regardless of what the document says.

Neither WeFix nor Pimlico holds both accreditations. GEM 24/7 does. That means our EICR certificates are valid under either scheme โ€“ a distinction that matters to letting agents managing portfolios across multiple local authority areas with different inspection preferences.

Need an EICR for your rental property? We issue same-day EICR certificates under both NICEIC and NAPIT. Valid for landlord compliance.
