Shed Alarm Buying Guide

Theft from garden buildings is on the rise. This may be because more people use sheds for storing valuable items or because we protect our homes better and so thieves opt for softer targets. Luckily, it is easy to protect your garden building such as sheds, garages, summer houses and even caravans with a shed alarm.

Many of us have buildings in the garden that we use for storage, office space and garden rooms. Using the space in our garden is a great way to extend the living space in our homes – as long as we remember to consider security.

If you have anything of significant value in your shed or garage, such as expensive tools, or bikes, then obviously an alarm is vital. However, even if you don’t have anything of value in your shed it is still well worth protecting it with an alarm as thieves could use tools, such as ladders and hammers to access your home.

Battery operated shed alarms provide a cost-effective way to protect garden buildings and prevent the theft of valuable items such as tools, bikes and garden furniture as well as deterring thieves and preventing damage to the buildings themselves.

Many can be used free standing or are easily mounted using the fixings provided.

Many battery-operated shed alarms come with a remote control to activate and deactivate them which can be convenient as you can deactivate the alarm before entering the building. These remote controls are either wireless or radio controlled. Of course, you will need to keep the remote control in a convenient but secure place. Other types have a pin system which is handy if you have a tendency to lose remote controls! With the pin system, you have a few seconds after entering the building to de activate the alarm.

Battery alarms emit a very loud siren which will deter opportunistic thieves. However, if you have very valuable items in an outbuilding, such as expensive tools or a home office, then you might want to consider a more comprehensive home security system.


I have a battery-operated alarm on my shed. What other measures can I take to secure my belongings?

A shed alarm is an excellent deterrent for intruders, however, you also want to make sure your shed is secured with a heavy-duty padlock and hasp that are difficult to remove with bolt cutters. Ensure that the hinges on your shed door are well made, too.

In addition, making sure the fences and gates around your garden are secure will help prevent thieves from getting access to your garden in the first place. Motion triggered security lighting provides another excellent deterrent to protect your property and wireless security lights are very easy to set up. In addition, you can buy a sign that says ‘this shed is alarmed’ to deter criminals from attempting a break in.

You should avoid storing very expensive items in a shed or outbuilding. These should be stored indoors or in a secure garage, preferably with a wired alarm. In addition, always ensure that items stored in sheds and outbuildings are covered by your home contents insurance policy for added peace of mind. You can also mark items with a special pen which will make it easier for the items to be returned to you if they are found by the police.

Can’t I use my home alarm to extend to my garage and shed?

A home security system can be extended to cover sheds and outbuildings, but this can be an expensive option. An outbuilding may need to be in a different zone from your home so that it can be secured even when you are at home during the day. Often a standalone alarm is a simpler more cost-effective option.

I don’t have anything of value in my shed, so an alarm might make a thief think I have something of value in there and may make them more likely to break in. Would I be better off not having an alarm?

First of all, many wireless alarms are fitted to the inside of the shed and there will not necessarily be any sign that the shed is alarmed. Secondly, while there may not be anything of value in your shed, you should still install an alarm if there is anything in the shed that could be used to assist a break in to your home, for example, ladders, hammers and other heavy tools.
