Buildings insurance may cover the structure of a shed, garage or outbuilding. Contents insurance is the part that may cover belongings stored inside them, such as tools, bikes or garden equipment. Even if your home insurance covers theft from a shed, garage or garden, it may not pay the full cost of replacing everything. When we last analysed home insurance policies, cover for garden features such as plants, trees and ornaments ranged from £1,000 to more than £100,000. This means that a claim may be rejected or reduced if items were stolen from an unlocked shed, garage or outbuilding.
