Answer: Insurance Group 31 is classified as a high-risk category in the UK’s 1-50 insurance grouping system. Vehicles in this group typically have powerful engines, expensive repair costs, or high theft rates, leading to above-average premiums. While not the highest (Group 50 is peak), Group 31 policies cost 45-70% more than mid-range groups like 20-25.

- Luxury SUVs: 2023 Land Rover Discovery Sport (£1,842 avg. premium)
- Performance Sedans: BMW M340i xDrive (0-60mph in 4.4 sec)
- Electric Vehicles: Tesla Model Y Long Range (battery replacement: £18,000)
- Imported Models: Right-hand drive US imports with limited UK repair networks
The prevalence of luxury SUVs in this category stems from their combination of high market value and complex all-wheel-drive systems requiring specialist maintenance. Performance sedans often land here due to their powerful engines increasing accident severity risks – a BMW M340i’s repair bill after a 40mph collision averages £11,200. Electric vehicles present unique challenges with battery vulnerabilities; a minor undercarriage impact on a Tesla Model Y can necessitate £14,000+ in structural repairs. Imported vehicles face double jeopardy: 62% longer parts delivery times compared to UK-market models and 35% higher labor costs for certified technicians.
Why Do Group 31 Premiums Vary by Region?
Postcode risk ratings create dramatic differences:
- London: £2,100 avg. (33% theft rate surcharge)
- Manchester: £1,950 (25% accident density markup)
- Edinburgh: £1,550 (15% “low risk” discount)
- Rural Wales: £1,400 (10% mileage reduction bonus)
Can Modifications Lower Group 31 Insurance Costs?
Strategic upgrades may reduce premiums by 12-18%:
- Security: Thatcham Cat 5 immobilizers (£350 install, 8% discount)
- Telematics: Black box policies (max 23% savings with safe driving)
- Suspension: Lowering kits reducing rollover risk (5% premium cut)
- Engine Remapping: Insurers may void policies – consult first
How Has Group 31 Changed Since 2020?
Industry shifts impacting Group 31:
- EV Surge: 41% increase in electric/hybrid Group 31 placements
- Part Shortages: 22% longer repair times increasing claim costs
- Tech Inflation: ADAS sensor replacement costs up 63% since 2021
- Crime Trends: Keyless entry thefts now 54% of Group 31 claims
The pandemic’s supply chain disruptions fundamentally altered Group 31 dynamics. Average wait times for luxury vehicle parts ballooned from 11 days in 2019 to 34 days in 2023, forcing insurers to cover extended rental car costs. Cybersecurity has become paramount – 68% of 2023’s Range Rover Sport thefts exploited keyless entry vulnerabilities. Electric vehicle dominance grows problematic: replacing a single damaged battery module in a Mercedes EQS costs £6,800, while full pack replacements can exceed £28,000. Insurers now use predictive modeling to adjust groups quarterly rather than annually, with high-risk models like the BMW X5 moving from Group 29 to 33 within 18 months.
“Group 31 represents a perfect storm of performance and expense. We’re seeing insurers deploy AI-driven risk modeling that analyzes 400+ data points per vehicle. My advice? Always cross-check your group placement using the ABI’s calculator – 18% of automaker-provided group ratings are outdated within 2 years due to changing claims data.”

Conclusion
Insurance Group 31 sits firmly in the high-risk tier, with premiums reflecting complex risk factors. While unavoidable for many drivers, strategic choices like enhanced security, regional registration, and modified coverage options can mitigate costs. As automotive technology evolves, Group 31 vehicles may see shifting risk profiles – regular policy reviews are essential.
