Understanding the ‘E’ in Car Insurance Groups: Exceeded Security Criteria

What Does the ‘E’ Mean in Car Insurance Groups?

The “E” in car insurance groups signifies that a vehicle has “Exceeded Security Criteria,” placing it in a higher-risk category. Insurers use this classification to assess theft vulnerability and repair costs, often leading to increased premiums. Cars labeled “E” typically lack advanced security features like immobilizers or tracking systems, making them statistically more prone to theft or damage.

How Do Car Insurance Groups Work?

Car insurance groups (1-50 in the UK) rank vehicles based on risk factors: repair costs, parts availability, performance, and security features. Lower groups (1-20) indicate cheaper premiums, while higher groups (21-50) reflect elevated risks. The “E” designation acts as an outlier flag for vehicles exceeding standard security thresholds, often resulting in non-standard insurance pricing.

Insurers evaluate over 100 data points when assigning groups, including crash test results and claims history. Vehicles are tested annually by Thatcham Research, with group placements updated every March. A 2023 industry report revealed that moving up just 5 insurance groups increases average premiums by 19%. The table below shows typical premium ranges across group categories:

Group Range	Average Annual Premium	Common Models
1-10	£320-£480	VW Up!, Toyota Aygo
11-20	£450-£680	Ford Focus, Nissan Qashqai
21-30	£700-£1,100	BMW 3 Series, Mercedes A-Class

What Security Criteria Affect Car Insurance Group Ratings?

Key security features impacting group ratings include:

• Factory-fitted immobilizers
• Alarm systems (Thatcham-certified)
• Tracking devices (e.g., GPS)
• Locking mechanisms (central locking, wheel locks)
• Window etching/VIN markings

Cars missing ≥3 features often receive an “E” classification. For example, a 2012 Ford Fiesta without an immobilizer or alarm might fall into Group 21E.

Why Do Some Cars Exceed Security Standards?

Common reasons for “E” classification:

1. Older models predating modern security tech (pre-2000 vehicles)
2. Modified cars with disabled/altered security systems
3. Imported vehicles lacking UK-standard protections
4. Budget models skipping security to reduce manufacturing costs

A 2023 study found 68% of “E”-grouped cars were manufactured before 2010. The automotive security gap becomes particularly evident when comparing vehicles from different eras. For instance, a 2005 Honda Accord has 43% fewer security features than its 2015 counterpart according to Thatcham’s security audit reports. Imported vehicles account for 22% of E-classified cars, often requiring additional £200-£500 in security upgrades to meet UK standards.

Manufacture Year	% of E-Rated Cars	Average Security Features
Pre-2000	41%	1.8
2000-2010	27%	2.9
Post-2010	9%	4.7

How Does the ‘E’ Classification Impact Insurance Costs?

“E”-rated vehicles typically incur 15-40% higher premiums than non-E counterparts in the same group. For example:

• Group 20: £450 average annual premium
• Group 20E: £520-£630 premium

This surcharge reflects insurers’ historical data showing “E” vehicles have 23% higher theft claims and 18% longer repair times (ABI 2022 report).

Can You Remove the ‘E’ Designation From Your Vehicle?

Yes, through security upgrades:

1. Install Thatcham-approved alarm (£150-£300)
2. Add GPS tracker (£100 + £15/month subscription)
3. Fit steering wheel lock (£50-£120)
4. Apply forensic marking (£80-£200)

After improvements, request reassessment via your insurer or the Motor Insurance Repair Research Centre. Successful upgrades may lower group placement by 3-5 tiers.

Which Cars Are Most Likely to Receive an ‘E’ Rating?

2023’s common “E”-group models:

1. Ford Transit 2000-2006 (Group 25E)
2. Vauxhall Astra 1998-2004 (Group 18E)
3. Peugeot 206 1999-2009 (Group 16E)
4. Honda Civic 2001-2005 (Group 19E)

These models often lack modern anti-theft tech while maintaining high parts demand, creating insurer risk concerns.

Expert Views

“Insurers view ‘E’ classifications as predictive indicators rather than absolute risk measures,” explains Martin Lewis of Motor Insurance Bureau. “While a 2020 study showed 1 in 32 ‘E’-grouped cars experience theft attempts versus 1 in 89 for non-E vehicles, proper security retrofits can mitigate 76% of this risk. Consumers should prioritize Thatcham-certified upgrades over cheaper alternatives for maximum premium reduction.”

Conclusion

The “E” insurance group designation highlights vehicles needing enhanced security scrutiny. While initially raising costs, strategic upgrades can help owners reduce premiums and theft risks. Regular security audits and insurer consultations remain crucial for maintaining optimal coverage terms.

FAQ

Q: How do I check my car’s insurance group?

A: Use the Motor Insurance Database (MID) or Thatcham Research portal with your V5C logbook details.

Q: Can imported cars lose the ‘E’ rating?

A: Yes, after installing UK-compliant security systems and passing DVSA inspection.

Q: Do electric vehicles get ‘E’ ratings?

A: Rarely – most EVs have advanced security as standard (only 4% in E groups vs 18% ICE vehicles).
