Makes getting new insurance difficult as you can't say "no" to the "have you every been declined or had insurance cancelled".
Even if you do say you've never been declined insurance, most insurance companies these days submit your details to the CUE (Claims and Underwriting Exchange) database which any insurer who signs up to this can check. All the details about the what's, when's and whys will be on there so you are totally screwed either way.
Insurance companies and other agencies share information a lot more than people realise. And they are also very proactive in looking for information like this too.
Since starting work at the new place (third largest motor insurer in the country who also insure most other risks) it's bee a massive eye opener!
What's been cool though, is even though I work in IT, I've been sent on various insurance training courses about everything from underwriting to fraud
