Not to toot my own horn, but honestly there isn’t anything - as far as we’re aware. We keep an eye on what other modern-style options exist, but there doesn’t seem to be anything which covers annual car insurance needs.
The reason is very simple: in the world of price comparison websites, it just isn’t possible for a startup to offer competitive annual insurance pricing. They can offer it, but they would get near-zero sales as it would cost too much.
In the price comparison marketplace (which is essentially all of the annual sales volume), the only way to get any volume at all is for the broker to take a negative commission (i.e. they pay for the customer) and for the underwriter to lose money. Then they jack up the prices for renewal and try to balance against the losses.
