What an EICR tests
An EICR examines the consumer unit, all fixed wiring, sockets, switches, lighting circuits and the earthing/bonding arrangement. The electrician performs both visual checks and live tests — insulation resistance, polarity, continuity, earth-loop impedance and RCD operation. The full inspection of a typical 3-bed home takes 2–4 hours; older or larger installations take longer.
The four EICR codes — what each means
Every observation is graded against a standard scheme:
- C1 — Danger present, immediate remedial action required. Power must be isolated from the affected circuit.
- C2 — Potentially dangerous, urgent remedial action required.
- C3 — Improvement recommended (does NOT make the report unsatisfactory).
- FI — Further investigation required without delay.
Satisfactory vs Unsatisfactory
A report is 'Unsatisfactory' if it contains any C1, C2 or FI code. Landlords must remediate within 28 days (or sooner if specified by the electrician) and provide written evidence to the tenant and, if requested, the local authority. A C3-only report is Satisfactory — improvements are advisory, not mandatory.
How often is an EICR required?
Since June 2020, all rentals in England require an EICR every 5 years OR at every change of tenancy, whichever is sooner. The certificate must be served on the existing tenant within 28 days of inspection, on a new tenant before move-in, and on the local authority within 7 days of any request. HMOs follow the same 5-year cycle.
How much does an EICR cost in 2026?
EICRs in Greater Manchester start at £130 for a 1-bed flat and scale with the number of circuits. A typical 3-bed semi runs around £170. There is no travel surcharge within the GM postcode area. Bundling with EPC and Gas Safety via a Landlord Compliance Package saves £40–£70 versus separate bookings.
What to do if your property fails
Don't panic — most failures are routine: a missing RCD, an unenclosed junction box, a slightly low insulation reading. Ask the inspecting electrician for a remedial quote on the day. Common remedials cost £80–£600 depending on findings. After remediation, a Minor Works Certificate or new EICR confirms the property is now Satisfactory and resets the 5-year clock.
Why older Greater Manchester properties fail more often
Greater Manchester has a high proportion of pre-1980s housing — Victorian terraces in Manchester, mining-era terraces in Wigan, mill cottages around Oldham and Rochdale. Many still have rubber-sheathed cabling, fused metal consumer units or no RCD protection. These almost always trigger C2 codes and warrant a partial or full rewire.
