Why Your Car Insurance Renewal Is Higher Than Last Year

If your car insurance renewal quote arrived recently and the number made you wince, you're not alone. UK motor insurance premiums have risen significantly over the past three years, with the Association of British Insurers reporting average comprehensive premiums up by over 25% between 2022 and 2024. The causes are structural, not temporary.

What's Actually Driving the Increases?

Vehicle Repair Costs

The single largest factor. Modern vehicles are significantly more expensive to repair than their predecessors. Advanced driver assistance systems (ADAS) — cameras, radar sensors, lane-keep assist components — are positioned in vulnerable areas and require recalibration after even minor impacts. A bumper repair that would have cost £300 in 2019 may now cost £600–£900 when ADAS recalibration is included.

• Average repair cost per claim has risen approximately 30–35% since 2021
• ADAS recalibration is now required after the majority of front or rear impact repairs
• Specialist technician time for EV high-voltage systems costs more than conventional labour
• Parts supply chain disruption post-2020 has driven up the cost of original equipment parts

Electric Vehicle Repair Complexity

EV insurance is consistently more expensive than equivalent petrol or diesel vehicles. Battery pack damage — even in relatively minor impacts — can total a vehicle that appears externally undamaged. Battery replacement costs of £8,000–£20,000+ are not unusual.

Theft Claims

Vehicle theft — particularly via relay attacks on keyless entry systems — has increased significantly. Each theft claim is high-value, and the pattern of professional organised theft is difficult for insurers to counteract through standard underwriting.

What You Can Do at Renewal

Never Auto-Renew

• Start comparing at least three weeks before renewal — early quotes are sometimes lower
• Use aggregators but also check direct-only insurers not on comparison sites (Direct Line, Aviva)
• If you find a significantly better quote, call your current insurer — many will match or beat it

Review What You're Declaring

• Annual mileage: overestimating is common and expensive — declare your realistic expected mileage
• Where the car is kept overnight: if you've started parking in a garage, update this
• Named drivers: removing an infrequently used named driver with a poor claims history can help

Excess and Add-Ons: What's Worth Paying For

• Voluntary excess: increasing from £250 to £500 often reduces premiums — only raise it to a level you can cover
• Legal expenses cover: typically £20–£30/year and worth having
• Breakdown cover: usually cheaper purchased directly from AA/RAC than bundled through insurance
• Key cover and personal belongings: check if these are covered through your home insurance first
• No-claims discount protection: worth considering if you have 4+ years NCB
