Avoid any of the Admiral group of insurers as their cover is pathetic

Admiral, Elephant, Diamond etc
They are quite happy to hike your premium for your add ons but when the get pinched they will only refit the standard equipment

And I won't even start on the problems my sister had with them after a non fault accident
HIC, Greenlight, Adrian Flux, Liverpoool & Victoria are all worth a call. Don't be so worried about cheap cover be more concerned about good cover. I learnt the very hard way about saving a few quid on the insurance. It cost me almost £2500
