Why Car Insurance Has Increased (Market Factors)
The whole market has seen significant premium increases in 2025-2026:
| Factor | Impact |
|---|---|
| Repair costs | Parts more expensive, labour costs up 20%+ |
| Vehicle theft | Keyless car theft epidemic |
| Claims inflation | Everything costs more to repair |
| Ogden rate changes | Large injury compensation increased |
| Electric vehicles | More expensive to repair |
| Advanced driver aids | Sensors, cameras cost more to replace |
Average UK premiums have risen 30-40% since 2023.
Top Reasons YOUR Premium Increased
1. You Made a Claim
Even a non-fault claim can increase premiums:
- You accessed your policy (statistical risk increase)
- Non-fault claims still appear on your record
- No claims discount reduced or removed
Fault claim: Expect 30-100%+ increase Non-fault claim: Expect 10-30% increase
2. You Lost No Claims Discount (NCD)
| Years NCD | Typical Discount |
|---|---|
| 1 year | 30% |
| 2 years | 40% |
| 3 years | 50% |
| 4 years | 55% |
| 5+ years | 60-65% |
One at-fault claim can drop you several years — losing perhaps 30% off the discount.
Protected NCD limits this but costs extra.
3. Points on Your Licence
| Violation | Points | Impact on Premium |
|---|---|---|
| Speeding (SP30) | 3 | +5-15% |
| Using phone (CU80) | 6 | +15-30% |
| Drink driving (DR10) | 11+ | +50-100%+ (if covered at all) |
| Careless driving (CD) | 3-9 | +15-40% |
Points stay on your licence 4-11 years depending on offence. Some insurers are stricter than others.
4. You Moved to a Higher-Risk Postcode
Insurance is heavily linked to where you live:
- Urban areas: More expensive (theft, accidents)
- High-crime postcodes: Premiums double vs safe areas
- Northern Ireland: Historically expensive
Moving even a few miles can significantly change your premium.
5. Your Car Is Now a Different Insurance Group
Cars are rated 1-50 on insurance groups:
| Group | Examples | Relative Cost |
|---|---|---|
| 1-5 | Small, low-power cars | Cheapest |
| 10-15 | Family cars | Moderate |
| 20-30 | Performance, luxury | Expensive |
| 35-50 | Sports cars, high theft targets | Very expensive |
Modified your car? Performance mods push up groups.
6. You’re Being Charged a Loyalty Penalty
FCA rules now limit price walking, but:
- Renewal quotes still often higher than new customer rates
- Insurers bet on loyalty/laziness
- Shopping around saves 20-40%
Always compare quotes before accepting renewal.
7. Your Age Changed Insurance Band
| Age Bracket | Impact |
|---|---|
| 17-24 | Most expensive (inexperience) |
| 25-30 | Significant drop from under-25s |
| 30-60 | Generally cheapest |
| 65+ | May start increasing again |
| 75+ | Some insurers won’t cover |
If you’ve crossed a threshold (e.g., turned 25), you might expect savings — but other factors can offset this.
8. Your Mileage Estimate Changed
Higher mileage = more risk:
| Annual Mileage | Impact |
|---|---|
| Under 5,000 | Lowest premiums |
| 5,000-10,000 | Moderate |
| 10,000-15,000 | Standard |
| 15,000+ | Higher premiums |
If you estimated higher mileage this year, premiums rise.
9. The Car Is Now Older
Age affects value (and therefore payouts) but also repair complexity:
- Very old cars: Cheap to replace but hard to find parts
- “Sweet spot”: 3-8 years often cheapest
- Classic cars: Specialist policies may be cheaper
10. Your Job Title Changed
Some jobs are seen as higher risk:
- “Journalist” more expensive than “Editor”
- “Chef” more expensive than “Caterer”
- Students, delivery drivers, sports professionals often expensive
Check if a legitimate alternative job description helps.
How to Reduce Your Premium
Before Renewal
- Start shopping early: Compare 3-4 weeks before renewal
- Use multiple comparison sites: GoCompare, Confused.com, MoneySuperMarket, Compare the Market
- Try direct insurers too: Direct Line, Aviva, NFU Mutual (not on comparison sites)
- Call your current insurer: With a cheaper quote, ask them to match
Quick Wins
| Action | Potential Saving |
|---|---|
| Pay annually (not monthly) | 10-20% |
| Increase voluntary excess | 5-10% |
| Add experienced named driver | 5-15% |
| Reduce mileage estimate (if accurate) | 5-10% |
| Park on driveway or garage | 5-10% |
| Install dashcam (inform insurer) | 5-10% |
| Telematics (black box) policy | 10-40% (if you drive safely) |
Policy Adjustments
- Comprehensive vs Third Party: Counter-intuitively, comprehensive is often cheaper (better drivers choose it)
- Voluntary excess: Higher excess = lower premium (but more risk if you claim)
- Named drivers: An experienced parent as named driver can reduce young driver premiums
Long-Term Improvements
- Build years of no claims discount
- Keep licence clean
- Choose sensible car when buying next
- Consider where you live (extreme cases)
Young Driver Options
If you’re 17-24, insurance is extremely expensive. Options:
| Option | How It Helps |
|---|---|
| Black box/telematics | Prove you drive safely |
| Add parent as named driver | Reduces statistical risk |
| Low insurance group car | Groups 1-10 cheapest |
| Multi-car policy | Family policies sometimes cheaper |
| Pay annually | Avoid credit interest |
| Higher excess | Reduces premium |
Never front: Having a parent as main driver when you’re the real main driver is fraud. Insurers void policies and prosecution is possible.
How Claims Affect Future Premiums
At-Fault Claims
Expect premiums to rise for 3-5 years:
- Year 1: 30-100% increase
- Year 2-3: Gradually reduces
- Year 4-5: Returns to normal if no further claims
Non-Fault Claims
Still recorded:
- May increase premium 10-20%
- Insurers see you as statistically riskier
- Impact reduces if you stay claim-free
Windscreen Claims
Usually treated separately:
- Often doesn’t affect NCD
- May still appear on record
- Some policies include windscreen cover
Understanding the Renewal Letter
Your renewal documents must show:
- Last year’s premium
- This year’s premium
- Clear comparison
The FCA requires insurers to highlight the difference and encourage you to shop around.
Look for: “We encourage you to check if you could pay less by shopping around.”
When to Consider Switching Insurer
- Renewal quote is 10%+ higher than quotes elsewhere
- You’ve been a loyal customer more than 2-3 years
- Better cover available at similar price
- You’ve had poor claims experience
When to Maybe Stay
- You have an ongoing claim
- Mid-policy cancellation fees are high
- Specialist cover (modified car, classic, business use)
- Strong existing relationship with insurer
