Read your terms and condition as they seem to be offering very little considering the policy is only two months old.
Try a few places, need2insure seem pretty good, speak to Paul B as he likes his RS's and is a nice chap.
Maybe look at classic policies as they may be cheaper, you don't earn ncd, but then the policies can often be so cheap you wont care.
