EICR Failed? What Basingstoke Landlords and Homeowners Need to Know


Receiving an unsatisfactory EICR result can be alarming. You’ve arranged an inspection expecting a straightforward certificate, and instead you’re handed a report full of codes, observations, and a verdict that your electrical installation has failed. What does this actually mean? How serious are the problems? And what happens next?

Don’t panic. A failed EICR doesn’t mean your property is about to burn down or that you’re facing enormous repair bills. It means your electrical installation has issues that need addressing—some potentially urgent, others less so. Understanding what your report says and what actions are required helps you move forward calmly and efficiently.

This guide explains what a failed EICR means for Basingstoke landlords and homeowners, how to interpret the codes on your report, what remedial work typically involves, and the timescales you’re working within.

Understanding EICR Results

An EICR inspection results in one of two overall outcomes: satisfactory or unsatisfactory.

Satisfactory means your electrical installation is in acceptable condition with no defects requiring immediate attention. You’ll receive your certificate, valid for the period specified (typically five years for rental properties, up to ten years for owner-occupied homes).

Unsatisfactory means the inspection identified one or more defects serious enough to fail the installation. You won’t receive a satisfactory certificate until these issues are resolved and the installation is retested.

An unsatisfactory result doesn’t necessarily mean your entire electrical system is dangerous. It might be a single significant fault or several smaller issues that collectively warrant failure. The detail is in the observation codes.

EICR Codes Explained

Your EICR report lists observations using standardised codes that indicate the severity of each issue found. Understanding these codes helps you prioritise remedial work appropriately.

Code C1: Danger Present

The most serious classification. C1 indicates an immediate risk of injury or fire. Examples include exposed live conductors, severely damaged cables, or installations posing imminent danger.

C1 defects require immediate action. Your electrician may have already made the issue safe during inspection—disconnecting a dangerous circuit, for example. If not, you must arrange urgent repairs before the installation can be used safely.

C1 codes are relatively rare in occupied properties because obvious dangers are usually noticed and addressed. They’re more common in vacant properties, neglected rentals, or buildings with DIY electrical work.

Code C2: Potentially Dangerous

C2 indicates a serious defect that could become dangerous or cause injury under certain conditions. The risk isn’t immediate like C1, but it’s significant enough that the installation fails and remedial work is required urgently.

Examples of C2 defects include:

  • Missing or inadequate earthing
  • Lack of RCD protection where required
  • Overloaded circuits
  • Damaged cable insulation
  • Incorrect fuse ratings
  • Missing protective covers on consumer units

C2 codes are the most common reason for EICR failures across Basingstoke properties. Older homes in Old Basing, South Ham, and throughout the town often have installations that met standards when installed but no longer comply with current requirements.

Code C3: Improvement Recommended

C3 indicates a defect that doesn’t meet current standards but doesn’t pose an immediate or significant danger. These observations don’t cause your EICR to fail—they’re recommendations for improvement rather than requirements.

Examples include older wiring methods that remain safe but wouldn’t be used today, or installations that could be enhanced for better protection. You’re not obligated to address C3 observations, though doing so improves your installation’s overall safety.

Code FI: Further Investigation Required

FI indicates the inspector couldn’t fully assess something and further investigation is needed to determine whether a defect exists. This might be because access was restricted, testing wasn’t possible without causing damage, or observations suggested potential hidden problems.

FI codes require follow-up. Until investigation is complete, the full condition of your installation remains unknown. Depending on what the investigation reveals, additional codes may be added to your report.

What Causes EICR Failures?

Common reasons for unsatisfactory EICR results in Basingstoke properties include:

Outdated Consumer Units

Older fuse boxes without RCD protection fail current requirements. RCDs (residual current devices) provide crucial protection against electric shock, cutting power almost instantly if current leaks to earth. Installations without RCD protection typically receive C2 codes.

Properties across Chineham, Brighton Hill, and Kempshott built before the 1990s often retain original consumer units that need upgrading.

Missing or Inadequate Earthing

Proper earthing protects against electric shock by providing a safe path for fault currents. Older installations may have inadequate earthing arrangements, missing earth connections, or deteriorated earthing conductors. These serious defects warrant C2 codes.

Deteriorated Wiring

Cables deteriorate over time. Insulation becomes brittle, connections loosen, and protective sheaths crack. Properties with wiring over 30-40 years old—common across Basingstoke’s older neighbourhoods—may show deterioration warranting C2 observations.

Overloaded Circuits

Modern homes demand far more electricity than older installations were designed to supply. Circuits serving too many outlets, inadequate cable sizes for current loads, or overloaded fuse ratings create fire risks and receive C2 codes.

DIY Work and Poor Alterations

Previous owners or unqualified individuals may have added sockets, lighting, or other modifications that don’t meet standards. These alterations frequently cause EICR failures, particularly when discovered in properties across Popley, Winklebury, and throughout Basingstoke’s residential areas.

Bathroom and Kitchen Non-Compliance

Electrical installations in bathrooms and kitchens have specific requirements due to increased risk from water. Missing supplementary bonding, inadequate IP ratings on fittings, or incorrect zone compliance commonly cause C2 observations.

What Happens After a Failed EICR?

When your EICR returns unsatisfactory, you need to arrange remedial work to address the identified defects. Here’s the typical process:

Review the Report

Your electrician should explain the findings clearly, identifying which observations caused the failure and what work is needed to resolve them. Don’t hesitate to ask questions—understanding what’s wrong helps you make informed decisions.

Get a Remedial Quote

You’ll need quotations for the remedial work required. Your inspecting electrician can usually provide this, or you can seek quotes from other qualified electricians. Ensure quotes address all C1 and C2 observations specifically.

Complete Remedial Work

Once you’ve accepted a quote, remedial work proceeds. Timescales depend on the scope—simple consumer unit upgrades might take half a day, while more extensive work involving partial rewiring takes longer.

Retesting and Certification

After remedial work is complete, the installation must be retested. If all C1 and C2 defects have been resolved, you’ll receive a satisfactory EICR certificate. This may be a new full inspection or a targeted retest of affected circuits, depending on the work completed.

Timescales for Landlords

Basingstoke landlords face specific legal timescales following an unsatisfactory EICR.

Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020:

  • C1 defects: Must be addressed within 24 hours or as specified on the report
  • C2 defects: Must be addressed within 28 days or as specified on the report
  • Written confirmation: You must provide written confirmation of completed remedial work to tenants within 28 days of the inspection
  • Local authority: If requested, you must provide the report and evidence of remedial work to your local authority

Failing to meet these timescales can result in fines up to £30,000. Basingstoke and Deane Borough Council can also arrange remedial work themselves and recover costs from landlords who fail to comply.

Remedial Work Costs

Costs for addressing EICR failures vary based on the defects identified. Here’s what Basingstoke property owners can typically expect:

Consumer unit upgrade: £350-£750 Replaces outdated fuse box with modern unit including RCD/RCBO protection. Addresses one of the most common C2 observations.

Earthing improvements: £150-£400 Upgrades earthing arrangements to meet current standards. May involve new earth electrodes or improved bonding connections.

Circuit repairs: £80-£200 per circuit Addresses specific faults on individual circuits—replacing damaged cables, correcting connections, or installing appropriate protection.

Partial rewire: £1,500-£4,000 Required when multiple circuits have deteriorated wiring. Replaces cables in affected areas while leaving compliant circuits unchanged.

Full rewire: £3,500-£8,000+ Necessary when widespread deterioration or multiple serious defects make comprehensive replacement more practical than piecemeal repairs.

Most EICR failures in Basingstoke properties require consumer unit upgrades plus minor additional work, typically costing £500-£1,200 to resolve. More serious failures involving extensive remedial work are less common but do occur, particularly in older properties that haven’t been maintained.

Can I Challenge a Failed EICR?

If you believe your EICR result is incorrect, you can seek a second opinion from another qualified electrician. However, be cautious—if the original inspection was conducted properly, a second inspection should reach similar conclusions.

Genuine disputes are rare because EICR testing follows standardised procedures with objective pass/fail criteria. If your installation lacks RCD protection, for example, that’s a measurable fact rather than a matter of opinion.

What sometimes happens is that different electricians identify different observations. One might note a defect another missed, or interpret borderline situations differently. But the fundamental safety issues causing failure should be consistent across competent inspections.
