360 insurance costs and providers

[TVR_CS]

Just had my renewal quote through, jumping around £80 to £457. Looking to jump providers so wondering who people are using and how much you are paying? I seem to recall prices in the £200 to £300 being mentioned previously? I have managed to build up 6 years no claim bonus, car is garaged in a decent area up’ north?
Cheers
