>>3797 If in doubt, declare it. Most insurers don't rate them, and most of those that do don't count it as a "proper" claim, so it might only add a few quid to your premium. Worst case if you declare it is you pay a bit more. Worst case if you don't declare it is your policy voided for material non-disclosure, with all the consequences that entails (declaring that fact for life, potential vehicle seizure, etc.).
>>3799 Note that it's probably the dirt-cheapest that will tend to care more about it, but then again they tend to be the ones with the most awful claims handling so if you've got any sense you'll probably be avoiding them anyway.
