Admiral for me.
They tried the usual trick with the renewal being more expensive than last year. Gave them a call and got the story about lots of claims on GTis. However, after 10 mins haggling the price came tumbling down...
£265 fully comp, inc class 1 business, £350 total excess. (I'm 31/8 years NCB/low risk postcode)
Just get on the phone and haggle with them!
