You need to view your insurance in the right way.
Some people seem to think they're all a bunch of b******s who you're forced to give your money to, and any means of cheating, lying and chancing your arm to get a few quid off your premium is fair game. This will ultimately bite you hard.
I'm a customer buying a service, I speak to my broker Greenlight like an adult and discuss things with them. If we both understand what is expected of each other, there's no surprises.
I have never had my premium increased for anything I've added/changed, except power... and even that was only about £50.
Another thing to remember. Anything you write on a forum is evidence, so all your build threads/sigs/posts about X, Y & Z are all there for insurance companies and the Police to see. If they can find any way not to pay you, they'll look for it...
