Previously I've received great service and great prices from Greenlight.
However unfortunately when I called recently I was told that they no longer have any underwriters willing to offer insurance for my postcode (SE9) so that's a large portion of people they now can't have as customers :( (population approx. 63k, dunno how many cars that is though lol)
Out of interest, how do my areas stats compared to any of yours who are still with Greenlight?
