They ask you on your renewal forms if you’ve been on a course according to the article, failure to own up would be the same as not coughing up to any other piece of information witheld, i.e. it would invalidate your insurance if they found out.
I can see their argument but I think it falls a bit flat when other elements of the info they use and have a significant effect on your premiums are so bluntly applied such as where you live. I also think if the industry could get it’s house in order to weed out fradulent claims and the claims handling industry they’d be in a better place arguing over how they calculate the premiums.
Still all a bit of a lottery if you get caught, especially with so many cameras offline. I can see the spy in the car boxs becoming more prevelant as they get cheaper. I’d have one if it knocked £100 off my premium a year, also give me the boot up the backside to drive more appropriately sometimes.
