Once you find a better quote, it can pay to contact your current insurer and see if they can beat it.
It often appears to me they pluck figures at random, and some companies that are cheaper for one car are not for your next.
My last renewal quote was beaten by the same company I was already with on a comparison site by around £45, where they were the cheapest.
Needless to say a phone call got me the better price 

I often do this, particularly for broadband/phone but I haven't a lot of time for existing insurers who try to take advantage of you because
you have renewed a couple of times. Did try to ring Aviva in this instance but couldn't be bothered to wait in a 2 hour queue listening to garbage about doing things online. Sent them an email instead which failed to elicit a reply!
