I was planning to upgrade my shed security. The shed is actually part of an old cottage so is pretty solid with thick stone walls, stone slate roof and heavy wooden door. I was just going to upgrade the door really with heavy steel strap hinges bolted through the frame and door and a heavy grade lock like this one. also bolted in place.
The policy specifies a 5 lever lock which the door already has. It is a mortice lock so I think a decent crowbar could splinter it out of the door.
Anyway I emailed the insurance company with the above link asking if it would be ok and got this reply. “This lock does not appear to be 5 Lever, therefore when stored inside the outbuilding the bike should be secured through its frame to an immovable object using a Sold Secure Gold standard lock.”
No need to bother then..Sigh!
