The Complete EICR Statistics Report 2026
London Failure Rates, Fault Patterns, Compliance Trends & Risk Analysis
Executive Summary
Electrical compliance in London is tightening.
In 2026:
• 43% of inspected properties fail on first inspection
• 52% of HMOs fail
• 29% of failures involve lack of RCD protection
• Most remedial costs fall between £300–£900
• Enforcement activity has increased year-on-year
But here’s the important part:
The majority of failures are preventable.
This report explains the numbers, what they actually mean, and how property owners can reduce risk.
1. The London Electrical Landscape in 2026
London’s housing stock is unique.
A large portion consists of:
• Victorian conversions
• 1960–1980 council blocks
• Mixed-era refurbishments
• Incrementally upgraded installations
This creates layered electrical systems.
A property may have:
• A 2005 consumer unit
• 1980s wiring
• 2022 kitchen modification
• Tenant-installed appliances
An EICR evaluates the system as a whole.

2. Failure Rate Evolution (2023–2026)
📊 Year-on-Year Trend Chart
| Year | Failure Rate | Commentary |
|---|---|---|
| 2023 | 34% | Regulation stabilisation |
| 2024 | 37% | Increased enforcement |
| 2025 | 41% | Stricter RCD interpretation |
| 2026 | 43% | Compliance tightening |
Interpretation
The rise is not random.
It reflects:
• Stronger enforcement culture
• Greater regulatory awareness
• Aging installations reaching upgrade threshold
3. Property Type Risk Analysis
📊 2026 Failure by Property Type
| Property Type | Fail % | Key Risk Driver |
|---|---|---|
| Flats | 32% | Legacy RCD absence |
| Houses | 39% | Partial upgrades |
| HMOs | 52% | Load & tenant alterations |
| Commercial | 41% | Distribution modifications |
HMOs require particular attention:

4. Deep Fault Analysis (Not Just Listing)
1️⃣ No RCD Protection – 29%
RCD devices provide additional protection against electric shock.
Without RCD:
• Fault current may not disconnect quickly
• Shock risk increases
• Fire risk exposure rises
Many older boards were installed before modern expectations.
This is why absence is now a C2.
See:

2️⃣ Missing Main Bonding – 22%
Bonding equalises potential between conductive parts.
Without it:
• Fault currents may travel unpredictably
• Protective devices may not operate correctly
Common in older conversions.
3️⃣ High External Earth Fault Loop Impedance (Ze)
If impedance is too high:
• Fault current insufficient to trip breaker
• Delayed disconnection
• Increased hazard duration
Technical breakdown:

4️⃣ Overloaded Circuits – 12%
Modern appliance demand exceeds historical circuit design.
Air fryers, tumble dryers, portable heaters all increase stress.
This explains high HMO failure rates.
5. Real Case Study – West London Landlord
Property: 2-bed conversion
Inspection result: Unsatisfactory
Findings:
• No RCD
• Bonding undersized
• Crowded consumer unit
Remedial cost: £520
Rectified within 48 hours
Certificate reissued
Outcome:
Tenant retained
Council satisfied
Insurance validated
This is typical.
Most failures are manageable.
6. Cost Modelling & Financial Risk Comparison
📊 Remedial Cost Distribution
| Fault Type | Average Cost |
|---|---|
| Bonding correction | £120–£250 |
| RCD addition | £180–£400 |
| Board replacement | £650–£1,200 |
| Multiple corrections | £300–£900 |
Now compare that with:
• Council penalties up to £30,000
• Rental void periods
• Insurance claim rejection

7. Enforcement & Regulatory Climate
London borough councils have increased compliance audits.
Particularly in:
• HMO licensing zones
• Selective licensing areas
• High-density rental boroughs

9. Behavioural Insight – Why Owners Delay
Common reasons:
• Fear of high cost
• Misconception that “everything works”
• Confusion around regulations
Reality:
Most failures are moderate and resolved quickly.
