1. Staying loyal to your current motor insurer can be a costly mistake. Since motor insurance companies favour drivers who fit their 'ideal driver profile', rates for the same driver vary from company to company.

So shop around. Do your research. Compare as many car insurance quotes as possible before renewing your current policy.

2. Buying car insurance online can save you between 5% and 10% with some insurance companies.

3. Low risk occupations and membership of certain professional organizations qualify you for significant discounts with many insurers.

4. Check out the safety and security discounts to which you are entitled, e.g. airbags, anti-lock brakes, anti-theft devices, such as alarms and immobilisers; off-road parking in garages or driveways.

5. Don't forget your no claims bonus and other special discounts for drivers with a good safety record.

6. Look out for low-mileage discounts. Make sure not to overestimate your annual total.

7. Inquire about age-related discounts.

8. Find insurers that offer discounts for combining car and home insurance.

9. Consider whether it is worthwhile insuring other named drivers.

10. Remember that you can reduce your premiums by raising your excess/deductible, i.e. the amount you are prepared to pay on any claim.

11. Is the facility of a courtesy vehicle really worth the extra expense?

12. Give careful consideration to the differences between the principal types of cover: comprehensive; third party fire and theft; and third party only.

Since it is vital to be adequately covered at all times, the cheapest car insurance cover isn't always the best. Always buy the policy that provides you with the precise cover you need.
