How to Reduce Your Car Insurance

The average UK car insurance premium hit £924 in 2025 (ABI), and while the FCA’s ban on loyalty pricing has helped, there is still a huge spread between the cheapest and most expensive quotes for the same driver. The good news: most of the factors that determine your premium are within your control. This guide covers 15+ actionable tips, each backed by data from the ABI, FCA and MoneySavingExpert, to help you bring your car insurance costs down.

1. Compare quotes from multiple insurers

This is the single most effective way to reduce your car insurance. The FCA reports that drivers who compare and switch save an average of £120–£250 per year. Use at least two comparison services, then check direct-only insurers like Direct Line, Aviva and NFU Mutual, who do not appear on comparison sites.

2. Time your renewal correctly

When you compare matters as much as whether you compare. Research from MoneySavingExpert, based on analysis of millions of quotes, consistently shows that the cheapest prices are found around 21 days before your renewal date. Comparing too early (more than 30 days) or too late (within 7 days) tends to result in higher prices.

Set a calendar reminder three weeks before your renewal to start comparing. Do not wait for your renewal letter — by then, you are already losing the pricing sweet spot.

3. Adjust your voluntary excess

Your total excess is made up of two parts: the compulsory excess (set by the insurer) and the voluntary excess (chosen by you). Increasing your voluntary excess from £100 to £500 can reduce your premium by 10–15%. However, only increase it to an amount you can genuinely afford to pay if you need to claim.

4. Protect and build your no-claims bonus

Your no-claims bonus (NCB) is one of the most valuable discounts available. After five years of claim-free driving, you can earn up to 65% off your base premium according to the ABI. Protecting your NCB costs a small amount extra (typically £20–£60 per year) but means you keep the discount even if you make a claim.

Note that protecting your NCB does not protect your overall premium — your premium can still rise after a claim. But it does preserve the NCD percentage, which is a significant portion of your discount.

5. Choose a lower insurance group car

Every car in the UK is assigned to one of 50 insurance groups by Thatcham Research and the ABI. Groups 1–10 are the cheapest to insure. If you are buying a new car, checking the insurance group before you purchase could save you hundreds of pounds per year.

Factors that determine a car’s group include engine size, power output, value, repair costs, crash safety ratings and security features. Small-engined hatchbacks like the Toyota Aygo, Fiat 500 and Vauxhall Corsa consistently sit in the lowest groups.

6. Reduce your annual mileage

Insurers price partly on how many miles you drive each year. Fewer miles means less exposure to risk, so a lower premium. If you have switched to working from home or can reduce your commuting, update your estimated annual mileage. Dropping from 12,000 to 6,000 miles can save 5–10% on your premium.

7. Improve your vehicle security

Fitting a Thatcham-approved alarm, immobiliser or tracking device can reduce your premium by 5–10%. Insurers view these devices as reducing theft risk. If your car does not already have a factory-fitted immobiliser (most modern cars do), adding one aftermarket can make a meaningful difference.

8. Park off-road

Where you park your car overnight affects your premium. A locked garage is cheapest, followed by a private driveway, then a private car park. Parking on the street is the most expensive option because it increases the risk of theft, vandalism and accidental damage.

If you have access to a driveway or garage, make sure you declare this accurately when getting quotes. The saving can be 5–10% compared to on-street parking.

9. Consider telematics (black box) insurance

Telematics policies use a device or smartphone app to monitor your driving. If you drive safely — moderate speeds, smooth braking, avoiding late-night driving — your premium can be reduced by up to 30%. This is particularly effective for young drivers and anyone who drives carefully but has a limited no-claims bonus.

10. Add an experienced named driver

Adding an experienced driver (a parent, partner or spouse) with a clean driving record as a named driver on your policy can reduce premiums by 5–15%. The named driver must be someone who genuinely uses the car occasionally. Listing someone who never drives the car provides no benefit and could be considered misrepresentation.

11. Pay annually, not monthly

Monthly car insurance payments are essentially a credit agreement with the insurer. They charge interest, typically at 15–30% APR, which can add £100–£200 to your annual cost. If you can afford the lump sum, paying annually is always cheaper.

If you cannot pay annually, consider whether a 0% credit card could bridge the gap. Pay the annual premium on the credit card, then clear the balance before interest kicks in.

12. Check your cover level

Counterintuitively, comprehensive insurance is often cheaper than Third Party Only. This is because insurers view TPO buyers as higher risk (often younger, less experienced drivers). Always compare quotes for all three cover levels:

• Third Party Only — Legal minimum. Covers damage to other people and their property.
• Third Party Fire and Theft — Adds cover for your car if stolen or fire-damaged.
• Comprehensive — Full cover, including damage to your own vehicle.

13. Optimise your job title

Your occupation affects your premium because insurers view some jobs as lower risk than others. While you must always be truthful, many jobs have multiple legitimate descriptions. For example, “chef” and “kitchen manager” describe similar roles but may attract different premiums. MoneySavingExpert reports that job title variations can create premium differences of up to £100. Experiment with accurate alternatives when getting quotes.

14. Avoid modifications

Any modification to your vehicle — including alloy wheels, body kits, tinted windows, engine remaps, spoilers and even upgraded sound systems — must be declared to your insurer and can increase your premium. Some modifications (particularly performance-related ones) can double or triple your premium. If you are buying a second-hand car, check for undeclared modifications.

15. Consider multi-car insurance

If your household has two or more vehicles, a multi-car policy can save 10–20% on each vehicle. Providers like Admiral, Aviva and Direct Line all offer multi-car discounts. Each car keeps its own no-claims bonus, so a claim on one does not affect the others.

16. Remove unnecessary extras

Insurers often add optional extras during the quote process — breakdown cover, legal protection, personal accident cover, key cover, and more. Each one adds to the cost. Review whether you genuinely need them, or whether you already have equivalent cover elsewhere (for example, breakdown cover through your bank account or credit card).

17. Don’t assume loyalty pays

The FCA’s 2022 loyalty penalty ban means insurers can no longer charge you more at renewal than they would charge a new customer for the same product. However, this does not mean your renewal price is the cheapest available. Different insurers use different pricing models, so the cheapest provider for you last year may not be the cheapest this year. Always compare, even if you are happy with your current insurer.
