Most people don’t think about their electrical installation until something goes wrong. A tripping fuse. A burning smell near a socket. By then, the problem had been sitting there for a while. An EICR, Electrical Installation Condition Report, is how you find out whether your property’s wiring and circuits are safe before something worse happens. In London, where a large share of the housing stock is over 50 years old, this matters more than most people realise. Here is what the process of EICR testing in London looks like, from start to finish.
What an EICR Actually Checks
A competent electrician will examine the entirety of your electrical system. This means the consumer unit (fuse box), the fixed wiring, sockets, lighting fittings, switches, bonding, and the earth system. What the EICR testing in London looks at:
- Are the electrical circuits correctly protected?
- Are RCDs (Residual Current Devices) present and functioning?
- Are there signs of deterioration or damage to the electrical wiring?
- Are the earth and bonding systems up to the current standards?
EICR in London is not a surface-level check. The electrician tests each circuit individually. For a standard two-bedroom flat in London, the process usually takes two to three hours. Larger properties or those with older wiring take longer.
How Long Does It Take
That depends on the property’s size and age.
A studio flat might be done in under two hours. A four-bedroom Victorian terrace, the kind common in Battersea or Fulham, could take four to five hours. Some properties catch electricians off guard. Hidden fuse boards, shared meters in older mansion blocks, inaccessible ceiling voids. These add time to the whole process.
Access to your consumer unit is a must before the appointment. A locked cupboard and furniture in front of the fuse box can slow things down more than people anticipate.
The Report Outcomes
After the testing is done, the electrician writes a report. Each observation is assigned a code:
- C1: Danger is present. Immediate action is necessary.
- C2: Potentially dangerous. Remedial work is necessary.
- C3: Improvement is recommended. Not urgent but recommended.
- FI: Further investigation required.
A C1 or C2 means the certificate is issued as “unsatisfactory.” Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, landlords must arrange remedial work within 28 days of receiving the report, or sooner if the report specifies it.
A C3 does not fail the inspection. The certificate is still issued. The recommendation sits on record.
What Homeowners Should Consider
There is no legal requirement for owner-occupiers to get an EICR in London. That said, mortgage lenders and home insurers increasingly ask for one, particularly for properties built before 1970. If you are buying or selling, an unsatisfactory report can affect negotiations in ways that are hard to reverse once they start.
Getting tested before listing a property is something more sellers are doing now. It removes uncertainty on both sides.
Before You Book
Check that the electrician is registered with a government-approved scheme, NICEIC, NAPIT, or ELECSA. Only registered electricians can issue a legally valid EICR in London.
Ask for a full written report, not just a certificate. The observations and codes tell you far more than a pass or fail stamp ever will.
