Obviously cost of premium is a major factor but how can I find out for example, if they have UK call centres and help lines etc? If i do have an accident, the last thing I want is to be talking to someone in India who doesn't speak my language very well and doesn't understand my answer if it's not on the answer sheet in front of him/her 
The top insurers on the comparison site are Hastings Direct, Insure, Egg, Axa and Co-op.
Does anyone know anything good or other wise about any of those guys please?
