How Many Valuables In Your Shed or Garage and their Cost?

Have you ever thought about just how many valuables you have stored in your garage or shed. Many people keep their car in their garage. That alone justifies spending a few pounds to fit some type of alarm. However, car aside, have you ever thought what else is in your shed or garage.

Now I know that some people will also have their washing machines, or perhaps a fridge/freezer in there. Those two items alone are close to £700-1,000. Yet again it is worth spending £20 on even a basic shed alarm just to give you some peace of mind.

Tools & Gardening Equipment

For many home owners though it is their tools that really quickly add up. The simple gardening items like a lawnmower, strimmer, hedge clippers and various bits and pieces can quickly add up to around £500+

I did a quick check on my own gardening tools and found a couple of spades, a fork, edging tool, shears, strimmer, hedge clippers (2 sets), lawnmower, pots and a range of other small accessories. It doesn't take much to quickly add up to a lot of money. These are certainly worth protecting from thieves and burglars.

We would of course also advise strongly to make sure that you have good locks on your garage shed door. We have written a full article on thebest locks for shed doors .


Most guys will have a range of tools in their shed or garage. Think first of any power tools that you may have. Most will have a drill, cordless screwdriver, an electric saw etc. Those alone can very quickly add up. When you add to that tool boxes and all the hand tools that you may have accumulated over the years, I think they are worth protecting with some type of alarm

Home Insurance & External Buildings

Most household content insurance policies in the UK do not actually cover good stored in a shed or garage. You can of course have these added to your insurance policy for an additional charge.

Be very careful though if you are considering doing this. The detail as always is in the small print. Many insurance companies will want to know what type of security those premises, like a shed or garage may actually have.

They would recommend special types of locks and some may even insist on some type of approved alarm system. It is worth making the phone call to find out how to cover off anything you may have stored in your shed or garage.

Video on Shed Protection from the Police

I think you will agree that there is some useful advice offered in this video. Shed break ins are on the increase so it is worth taking as many precautions as you can. Fitting good padlocks and good alarms makes a great deal of sense.

Best Shed Alarm with Siren

Some owners prefer the idea of a shed alarm with an external siren. In essence they want something that detects motion, and then triggers a loud siren. The noise from that will almost always send thieves running for the hills.

It may also annoy the neighbours if it triggers when cats or dogs go by, so that is always worthwhile bearing in mind. The best way to avoid that is not to use a motion sensor and use a door contact instead.

The one that seems to get the best buyer reviews is the KERUI Standalone Home Office Shop Garage Security Alarm System Kit. A long name I know, but it gets good buyer reviews and is priced at under £30.

KERUI Standalone Home Office Shop Garage Security Alarm System Kit

  • This kit has a siren horn which according to buyers is loud, and most importantly loud enough to scare the XXXX out of thieves. The horn is weatherproof and has a noise level of up to 110 db (that is LOUD)
  • The door alarm uses remote controls to set security code for arming/disarming. The kit has a programmed main unit and sensors.
  • The kit includes a horn and two door/window sensors, two remote controls, and a PIR motion detector.
  • There is also an SOS button on the remote control, which will set off the siren alarm and this is good if only kids or older people are at home, and don't want to confront the burglar.
  • This can also send notifications to your phone once it has been paired

Best Shed Alarm Padlock

Another option that some buyers prefer is a good quality padlock that is also a siren. This one is great for garden sheds, but also useful for locking items like bicycles, scooters and even mobility scooters.

It is essentially a padlock, and you can choose to activate the alarm or not, depending on your circumstances. The reason most people will buy this type is of course to take advantage of the alarm.
