Phone you current insurer up with the quotes above and watch you £314 renewal come down in price.
I did this.
Was with Direct Line, have been for years, plus used them for home insurance.
Phoned them to add my wife to the policy. Their quote was almost double what I could get with another insurer.
They refused to budge on the premium. I cancelled and went elsewhere.
I’ve also cancelled the home insurance as I’ve got a much better price elsewhere.
Seems Direct Line are not at all interested in retaining customers
Similar here – we had been with Ford Direct for years but their price was double pretty much anything online and they could only offer a tiny (ie a couple of ££s) reduction so we moved.
