When people think about electrical faults, they often imagine flickering lights, tripping circuit breakers or sockets that stop working altogether. However, many electrical faults remain completely hidden and show no obvious signs during normal day-to-day use.
A recent Electrical Installation Condition Report (EICR) carried out in Banbury is a perfect example of why periodic electrical inspections are so important.
The Fault
During the inspection, testing of the ring final circuit revealed that there were no end-to-end continuity readings on the line and neutral conductors. This immediately indicated that faults were present somewhere on the circuit and that further investigation was required.
Although the sockets throughout the property appeared to operate normally, the test results confirmed that something wasn’t right.
This highlights an important point—just because your electrical installation appears to be working doesn’t necessarily mean it is operating safely or correctly.
Investigating the Problem
Rather than removing every socket throughout the property, I took a logical approach based on experience.
I began by checking the accessories that were most likely to have been altered during previous works. These included:
- A socket that had surface trunking installed.
- A socket located on a wall backing onto a property extension.
These are common locations where wiring may have been disturbed during renovations or alterations.
The investigation quickly identified the faults.
The line conductor fault was located at the socket with the surface trunking, while the neutral conductor fault was found at the socket backing onto the extension.
Without carrying out the EICR and subsequent fault-finding, these issues may never have been discovered.
Why Were the Sockets Still Working?
This is one of the questions I get asked most often.
Many homeowners assume that if a socket supplies power, then everything must be safe. Unfortunately, that isn’t always the case.
In this property, the sockets continued to function during normal use despite faults existing within the ring final circuit. This is exactly why visual inspections alone are not enough.
An EICR combines a thorough visual inspection with specialist electrical testing that can identify hidden defects that simply cannot be seen or detected during everyday use.
These tests verify that the installation is operating as intended and help identify issues before they develop into more serious problems.
How the Fault Was Repaired
Once both faults had been identified, the loose conductors were correctly reconnected and the affected accessories were reassembled.
The circuit was then fully retested, confirming satisfactory end-to-end continuity readings on the ring final circuit.
By retesting after the repair, it confirmed that the circuit had been restored correctly and was operating as designed.
Why Regular EICRs Matter
Electrical installations naturally deteriorate over time, and alterations carried out over many years can introduce faults that aren’t immediately obvious.
An EICR helps identify issues such as:
- Loose electrical connections.
- Damaged wiring.
- Missing or inadequate protective measures.
- Signs of overheating.
- Incorrect alterations.
- Hidden faults that everyday use won’t reveal.
Finding these issues early can prevent future problems, improve safety and provide peace of mind for homeowners, landlords and anyone responsible for maintaining a property.
Professional EICRs in Banbury
This job demonstrates exactly why electrical testing is so valuable. The homeowner had no indication that there were faults within the installation because everything appeared to be working normally.
Only through proper inspection and testing were the faults identified, repaired and confirmed as satisfactory through retesting.
If your property hasn’t had an Electrical Installation Condition Report for several years—or you’re purchasing a home, renting out a property or simply want reassurance that your installation is safe—an EICR provides an accurate assessment of the condition of your electrical system.
At L J Mullan Electrical, I carry out professional EICRs throughout Banbury and the surrounding villages, providing clear reports, honest advice and high-quality remedial work where required.
Sometimes, the biggest electrical faults are the ones you can’t see.
