I used GJW for a number of years but never had a claim which is the true test for any insurance company. Last year I decided to look around for competitive quotes instead of just auto renewing. I discovered I could get the same cover elsewhere for over £100 less! When i challenged GJW on this they claimed the market was volatile and offered to match the quote. I was not impressed at all, the insurance market is not that volatile and it left me with the impression i had been overcharged, probably for quite a few years. My insurance has just come up for renewal and again I went for a few quotes before I renewed.
My advice is to shop around annually, it is surprising how much money you can save, but do be sure you are getting like for like cover in the proposals.
