Why is there such a large difference in premiums across different areas?

According to This is Money, the huge disparity between car insurance costs across the country is mostly due to the varying risk profiles that insurers judge for pricing.

For example, the majority of accidents happen in towns and large cities. This translates to a higher risk profile, and drivers of cars in these areas are consequently likely to pay higher premiums.

Similarly, the rate of crime, including car theft, is higher in urban areas than in rural areas, meaning that drivers in rural areas are likely to pay lower premiums.

How can you cut your car insurance costs?

Even if you live in an area where car insurance costs are not exactly the cheapest, there are ways to cut costs.

Ultimately, the best way to make sure that you are not paying more than you need to on your car insurance is to shop around and compare different quotes. An easy way to do this is using car insurance comparison sites like MoneySuperMarket and

When comparing quotes, keep in mind that the cheapest option isn’t always the best. You shouldn’t take out a policy based on price alone. Make sure that you’ve done your homework on any policy that has piqued your interest to confirm that it covers everything you want and that the provider will actually pay out when you need them to.

Meanwhile, here are other ways to potentially cut your car insurance costs:

  • Limit your annual mileage
  • Pay for your insurance annually (to avoid interest charges)
  • Increase your voluntary excess
  • Add a second low-risk driver to your policy
  • Go for black box insurance, especially if you are a young driver
