Car insurance is one of the few recurring costs where doing nothing reliably costs you money. Insurers price renewals on the assumption that most customers will not shop around, and most customers do not.
Shop the whole market every year
This is the single biggest lever and the most neglected. Premiums for identical cover vary substantially between insurers, and the ranking changes year to year as companies adjust their appetite.
Get quotes from several insurers before every renewal. Include both large national companies and smaller regional ones, since the cheapest is unpredictable.
Loyalty is generally not rewarded. In several markets, charging existing customers more than new ones has become a regulatory issue precisely because it was so widespread.
Adjust the excess deliberately
Raising your deductible lowers your premium, sometimes considerably. The test is simple: could you comfortably pay the higher amount tomorrow if you had to?
If yes, the saving is usually worth it. If not, do not do it, because an unaffordable excess makes the policy less useful precisely when you need it.
Discounts people forget to claim
- Combining car and home or renter policies with one insurer.
- Insuring multiple vehicles together.
- Low annual mileage, particularly if your commuting changed.
- Defensive driving courses, which several insurers recognise.
- Occupational or membership discounts through employers, unions and associations.
- Paying annually rather than monthly, since instalments usually carry interest.
- Vehicle safety and anti-theft equipment.
- Good student discounts for younger drivers in education.
These are rarely applied automatically. Ask for each one by name.
Review the cover on older vehicles
Comprehensive and collision cover on a vehicle worth very little can cost more over a few years than the vehicle would pay out. Compare the annual cost against the realistic settlement value.
Be careful here: dropping this cover means paying for your own repairs entirely. It is a calculation, not an automatic saving.
Telematics and usage-based policies
Programmes that monitor driving can reduce premiums meaningfully for careful, low-mileage drivers. They can also increase them for drivers who brake hard or drive late at night.
Check whether the programme can raise your rate before enrolling, and understand what data is collected.
What does not help
Reducing liability limits to the legal minimum saves relatively little and exposes you to serious financial risk in a significant accident. This is usually the worst place to economise.
Cancelling mid-term to switch often incurs a fee that offsets the saving, so time changes to renewal where possible.
A simple annual routine
A month before renewal, get three quotes for identical cover, ask your current insurer to match the best, and confirm every applicable discount. Thirty minutes a year is usually the best-paid half hour in your household budget.
