I always go on at least 3 comparison sites every year, and always get different results. I think insurance companies just try it on to see what they can get away with.
Last year the insurer that I had been with for a couple of years suddenly upped the renewal quote by over £100. I went on my usual comparison sites and got a quote of less than I paid the previous year. I am now with a company who had previously quoted me much higher than the one I went with last time, if that makes sense.
I have never worked out why a company that gives you a ridiculously high quote one year can be the cheapest a few years later. Doesn't make any sense to me, and nor does the fact that one company gives a ridiculously high quote on one car, but is very reasonable on another. Then when you do a check you find another company rates the same cars the other way round.
