Just renewed the insurance on my car and every year it amazes me the prices some companies come up with. The advice is not to stick to your old insurance, yet I've been with mine for years. As instructors we don't have lots of insurance companies to chose from but the difference in price is astounding. One was 50% up on what I paid last year, while another wanted almost £900 and I was told that was a good deal. My old insurance company came up with the price of just over £400 then eventually after consideration I payed £367. Think of the profit the company asking nearly £900 must be making.
