Garden sheds are notoriously difficult to secure because they're usually unsuitable for mortice locks, leaving locks fitted to the face of the shed vulnerable to being ripped out.
Apart from valuable gardening equipment, the garden shed also provides a burglar with a supply of house-breaking implements. Even the best door and window locks, for example, may not withstand an attack from a garden spade.
Securing the shed door and windows
A sturdy padbolt or hasp and staple is the best way to secure a shed door.
Hasp and staples have concealed screws – this prevents a burglar from simply removing the lock to gain entry.
Windows can be protected with a grille. Any that open should be fitted with key-operated locks.
Protecting valuable items
Ground anchors can secure valuable items like lawnmowers or bikes inside a shed. Provided the shed has a suitable floor, with a beam or joist, the anchor is screwed in place and the items chained to it.
Shed alarm systems
You could also consider fitting a battery-powered alarm. These are triggered either when the door is opened or when motion is detected by an infrared sensor. They cost around £30.
Common sense security
Never leave keys, to the shed or home, under a doormat or flower pot. Instead, leave spare keys with family, friends or a trustworthy neighbour.
You may also wish to consider storing equipment, like spades, which could be used to attack your home in the garage rather than in the shed.
An outdoor security light which is triggered by movement acts as a deterrent, as does a gravel path which is noisy underfoot.
