Keeping Your Sheds and Outbuildings Secure
Garden sheds, garages and other outbuildings often contain valuable items, from bicycles and power tools to gardening equipment and outdoor furniture. Yet they can sometimes be overlooked when it comes to home security, making them an attractive target for opportunist thieves.
Whether attached to your home or situated at the end of the garden, taking steps to improve the security of your sheds and outbuildings can help protect your belongings and prevent criminals from gaining access to your property.
Why are Sheds and Outbuildings Targeted?
Sheds and outbuildings often contain high-value items that are easy to sell on, including:
- Power tools
- DIY tools and materials
- Lawnmowers and garden machinery
- Bicycles and e-bikes
- Motorcycles and scooters
- Camping and leisure equipment
In some cases, thieves may also steal tools to use in other crimes, such as breaking into homes or businesses.
Unlike the main house, sheds and outbuildings are often located out of sight, giving criminals more time to work without being disturbed.
The Scale of the Problem
Tool theft alone costs UK tradespeople and homeowners millions of pounds each year.
According to research, almost £19 million worth of tools were stolen in 2025, with a further cost in the millions of lost income from cancelled and delayed jobs.
Garden equipment is also frequently targeted. Aviva has previously reported that around three in 10 homeowners have experienced attempted or actual break-ins to their sheds or outbuildings.
While many incidents involve opportunist criminals, organised groups also target areas where multiple properties contain valuable equipment.
How Do Thieves Gain Access?
Many shed burglaries require very little effort. Common methods include:
- Forcing or cutting padlocks
- Prying open doors or windows
- Removing weak hinges
- Breaking lightweight panels
- Entering through unlocked doors
- Using tools found outside the property
Some offenders will first check whether expensive items are visible through windows or open doors before deciding whether to break in.
Others may enter gardens by climbing fences or through unlocked side gates before targeting sheds and garages.
Don’t Make It Easy for Criminals
Simple habits can significantly reduce the risk of theft.
- Avoid leaving expensive equipment in plain sight and always return tools and bicycles to secure storage after use
- Ladders, wheelie bins and garden furniture should also be stored securely, as they can be used to gain access to upper windows or help thieves climb over fences
- Avoid advertising valuable purchases by leaving branded packaging outside your property after birthdays, Christmas or home improvement projects
Strengthen Physical Security
A strong shed is only as secure as its weakest point. Consider improving security by:
- Fitting robust locks designed for external buildings
- Reinforcing doors and frames
- Using security screws or coach bolts on external hinges
- Installing laminated or reinforced glazing where appropriate
- Securing windows with suitable locks
Anchoring valuable items inside where possible
If you store bicycles, motorcycles or expensive tools, consider using additional internal security such as ground anchors or chains.
Improve Natural Surveillance
Criminals prefer to work where they cannot easily be seen.
Good lighting, trimmed hedges and appropriate positioning of sheds can improve visibility and increase the likelihood of suspicious activity being noticed.
Motion-activated lighting can also act as a useful deterrent, particularly during the darker months.
Where appropriate, CCTV can provide additional reassurance and valuable evidence should an incident occur.
Property Marking and Registration
Property marking is one of the simplest ways to make stolen items traceable.
Marking valuable equipment with a unique identifier and registering it on a recognised property database helps police identify recovered property and return it to its rightful owner.
Keep a record of:
- Make and model
- Serial numbers
- Photographs
- Purchase receipts
- Identifying marks
These details can also assist insurers in the event of a claim.
Be Mindful of Social Media
Posting photographs of new purchases, workshop projects or expensive equipment can unintentionally advertise what is stored at your property.
Consider whether images reveal:
- Valuable tools or machinery
- The layout of your garden
- Security arrangements
- Access points to sheds or garages
Limiting location information and adjusting privacy settings can reduce the amount of information available to criminals.
What to Do If Your Shed is Broken Into
If you discover that your shed or outbuilding has been burgled:
- Avoid touching anything unnecessarily, as forensic evidence may be present
- Report the incident to the police as soon as possible
- Photograph any damage
- Contact your insurer
- Update your security before replacing stolen items
If marked or registered property has been stolen, provide those details to the police.
