Anyone concerned about their insurance premium rocketing when @brand gets his bike nicked can relax.
No policy I know of will pay out on an unlocked bike, particularly outside the home.
You really must read what I wrote before posting :-
"I live rural where people leave the bikes unlocked even in town. When I go the pub in the village there is bikes all over the place some times left unlocked for weeks. I leave the bike in the yard in the back of the pub. There is often people grooming horses there, the landlady has the kitchen door open most of the time and can see it through the door. She pass it regularly to fetch food from the freezer and veg from the store. I can see it from the bar. I don't bother locking it!!"
This is the one pub only that I don't lock it up and the NFU manager (who drinks in the same pub) has never picked me up on that. And I am fairly certain that if I took my bike out of the garage and someone nipped up my drive while I nipped into get my wallet the insurance NFU would pay out.... wherever I told him I had left it unlocked or not.
