Many thanks for all your comments, very interesting. I have since contacted Admiral who came up with £700 and Headley who came in at £430.
Prices seem to be all over the place comparing my recent quotes with what others are paying with the same companies. My old Dad used to say never trust insurance companies lad there only there to feather their own nests!

As I said I was not after the cheapest quote but the most trustworthy and on the strength of your comments think I shall go with Headley. Thank you all very much.
