Is Your Shed and Everything Inside It Actually Insured?
Most of us don't give much thought to the value of what's sitting inside the garden shed.
The lawn mower gets pushed into one corner. Bikes lean against the wall. Power tools accumulate on shelves, the pressure washer gets tucked behind the gardening equipment, and cushions, barbecue accessories and outdoor furniture are stored away whenever the weather changes.
Individually, none of it necessarily feels remarkable. Add everything together, though, and the value stored at the bottom of your garden can quickly reach several thousand pounds.
That raises an important question: if your shed was broken into, damaged by a storm or affected by fire or flooding, would your home insurance actually cover the building and everything inside it?
The answer is often yes, but there is an important catch.
Different insurers, policies and levels of cover can treat sheds and their contents very differently. There may be separate limits for outbuildings, lower limits for theft, requirements around security and restrictions on particularly valuable belongings.
So rather than assuming everything in your shed is protected in exactly the same way as everything inside your house, it is worth spending a few minutes checking.
First, How Much Is Actually Sitting in Your Shed?
Before thinking about insurance, take a mental walk through your shed.
Perhaps there's a £600 lawn mower, two bicycles worth £1,500 between them, £700 of power tools, a £250 pressure washer, £500 of gardening equipment and another £1,000 of garden furniture and barbecue equipment.
That hypothetical shed already contains £4,550 worth of belongings.
Add an electric bike, premium power tools, gym equipment or equipment for a hobby and the figure can rise considerably further.
This isn't simply theoretical. Aviva reported that the average value of its shed and outbuilding theft claims during 2025 was £4,567. Its research also identified power tools, bicycles and e-bikes, lawnmowers and other garden equipment amongst commonly stolen items.
The problem is that sheds tend to accumulate belongings gradually. Few people spend £5,000 filling a shed in one afternoon. Items are bought over several years, which makes it surprisingly easy to underestimate their combined value.
That's why the first step is simply to work out what you actually own.
Is a Garden Shed Covered by Home Insurance?
A garden shed will often be treated as a domestic outbuilding under buildings insurance, provided it meets the conditions of the individual policy.
Buildings insurance generally concerns the structure itself. That could include the shed's walls, roof, windows and doors rather than the belongings stored inside.
For example, Aviva states that domestic outbuildings at the insured address are automatically included within its buildings cover, subject to policy limits and exclusions.
Halifax similarly describes its outbuildings cover as applying to detached structures including sheds, summer houses and garages.
That distinction between the building and its contents is important.
If a storm damages the structure of your shed, that may be a buildings insurance matter. If somebody breaks into the shed and steals your lawn mower, bicycles and tools, those belongings would generally fall under contents insurance instead.
LV= explains the distinction particularly clearly in its current shed insurance guidance. Buildings insurance can protect the structure against insured events, whereas contents insurance is what protects eligible belongings stored inside.
However, having both types of home insurance doesn't automatically mean that everything is covered without limits.
The Contents Limit Could Be Lower Than You Expect
Your overall contents insurance might provide substantial cover for possessions inside your home, but some policies place separate limits on belongings stored in garages, sheds and other outbuildings.
The difference between insurers can be significant.
Aviva currently states that its Signature contents insurance provides up to £7,500 for theft of contents from garages or outbuildings, with different provisions applying to other types of insured claims. AvivaPlus operates differently, so customers need to check the exact product they hold.
Admiral provides an even clearer example of how dramatically different levels of cover can be within the same insurer. Its guidance, updated in April 2026, says its standard Admiral level provides no theft cover from sheds and outbuildings, while Admiral Gold provides up to £1,500 and Platinum up to £5,000.
LV= also varies its protection according to the policy selected. Its current contents insurance information states that theft from sheds and garages is covered up to £1,000 on Essentials, while Home and Home Plus can provide cover up to the selected contents limit, subject to the policy terms.
Halifax confirms that its contents insurance can cover items stored in detached outbuildings, including tools, gardening equipment, lawnmowers and other belongings, but directs customers to their individual policy schedule to confirm the cover they have selected.
The figures above are examples of current insurer information at the time of writing, not a guarantee of what your individual policy provides. Insurance products and terms change, so always check your latest policy schedule and wording.
Don't Forget About Individual Item Limits
The total contents limit isn't the only figure worth checking.
Some policies also have a maximum amount they'll pay for an individual item, particularly when it is considered high value.
Imagine you have £5,000 of outbuilding cover and assume that's enough because everything in the shed adds up to £4,000. If one of those items is a particularly expensive bicycle or piece of equipment, there may still be a separate individual limit or requirement for it to be specifically declared.
Aviva advises customers to check their single-item limit when storing particularly expensive belongings in sheds and outbuildings. LV= similarly advises customers to notify them if an item exceeds the policy's maximum single-item value so it can potentially be separately included.
Bicycles are particularly worth checking because insurers may have their own bicycle conditions, optional cover or specified security requirements.
The lesson is simple: don't just compare the total value of your shed with the headline contents limit. Check whether any individual item needs additional cover too.
Does Shed Security Affect an Insurance Claim?
Potentially, yes.
Owning contents insurance doesn't mean you can leave an outbuilding unsecured and automatically expect a theft claim to be successful.
Aviva specifically states in its current shed security guidance that outbuildings must be kept locked for a theft claim to be valid under the cover it describes.
Admiral similarly warns that insurers may reject a claim if there is no evidence that the shed was locked and that somebody forced their way inside.
The precise security requirements will depend on your insurer and policy, but the practical point is universal: if you're storing thousands of pounds worth of equipment in a shed, its physical security deserves the same attention as its insurance.
A good lock is only part of that.
Hinges secured properly to the building, strong doors, concealed belongings, window protection, lighting and securing expensive equipment inside the shed can all make the building considerably less inviting to thieves.
A visible security camera, like this Tapo Indoor & Outdoor Camera, or video doorbell can also act as a useful deterrent, particularly if your shed is positioned near a driveway, side access or garden gate. Motion-activated lighting can help too, making it much harder for someone to approach the building unnoticed. If you install cameras around your property, make sure they are positioned appropriately and that you follow current UK guidance around domestic CCTV and privacy.
We've covered these measures in much more detail in our guide, Beyond the Lock: Smarter Shed Security for Norfolk Gardens. It explains how locks, hinges, lighting, windows, internal anchors and modern security technology can work together rather than relying on one padlock to protect everything inside.
Your Shed's Condition Matters Too
Security is often what people think about first when discussing insurance, but the physical condition of the building matters for another reason.
A shed might contain belongings that would be expensive to replace, yet those items are only as well protected from the weather as the building around them.
A damaged roof covering can allow water inside. Rotten cladding can weaken the structure. Poor drainage around the base can create long-term damp problems, while an ageing door may become increasingly difficult to secure properly.
Insurance also isn't designed to replace normal maintenance.
For example, Aviva lists wear and tear and wet or dry rot amongst exclusions from its buildings cover information.
That is why waiting until a shed deteriorates significantly before carrying out maintenance can be a false economy.
A quick inspection a couple of times each year can identify lifted roofing, damaged cladding, worn locks, loose hinges and early signs of damp before they become larger problems.
If you're not sure what to look for, our How to Repair a Shed: From Roof to Floor guide takes you through the building from roof to floor and explains how to identify some of the most common problems.
Keep Evidence of What's Inside
If the worst does happen, being able to demonstrate what you owned can make matters considerably easier.
Aviva recommends keeping receipts for higher-value belongings because they may help during a claim. Admiral similarly suggests using receipts, bank statements or product details when calculating the value of shed contents.
You don't necessarily need an elaborate filing system.
Take photographs of the shed interior periodically. Photograph valuable tools and machinery individually. Keep digital copies of receipts where possible and record model or serial numbers for expensive equipment.
For bicycles, power tools and machinery, this information can also prove useful if an item is stolen and needs to be reported to the police.
It takes minutes to create a basic record but could save considerable frustration later.
Be Careful If Your Shed Is Used for Business
Garden buildings have changed enormously over the past decade.
They're no longer exclusively used for gardening equipment. Plenty of people now use sheds as offices, studios, workshops or spaces connected to small businesses.
That creates another insurance consideration.
Admiral warns that most standard home insurance policies don't automatically cover outbuildings used for business purposes and advises policyholders to tell their insurer about relevant business use. Clerical home-working may be treated differently, but the important point is that you shouldn't simply assume your domestic policy remains suitable after changing how the building is used.
If you've turned your shed into a workshop containing professional equipment, operate a business from it or regularly have customers visiting the property, speak to your insurer and explain exactly how the building is being used.
That way you can establish what cover is appropriate before you ever need to make a claim.
Could a More Secure Shed Make Sense?
Sometimes the issue isn't the insurance policy. It's the building being used to protect the belongings.
If your existing shed contains a collection of increasingly valuable bikes, machinery or tools, it may be worth asking whether the building itself is still appropriate.
A stronger, well-maintained garden building with good doors and sensible security features provides a much better starting point than trying to protect thousands of pounds worth of equipment inside an ageing structure with weak timber and a lightweight lock.
Windowless or security-focused sheds can also make sense where storage is the main priority. If nobody can see what's inside, there's less temptation for an opportunistic thief in the first place.
That doesn't mean every shed needs to resemble a vault.
It simply means the building should reflect what you intend to keep inside it.
A Five-Minute Shed Insurance Check
Before closing your shed door tonight, it's worth doing one quick exercise:
- Work out approximately how much everything inside would cost to replace.
- Check whether your home insurance includes the shed itself as an outbuilding.
- Check the contents limit specifically for sheds and outbuildings, especially for theft.
- Look for individual item limits covering expensive bikes, machinery or tools.
- Read any security conditions applying to theft claims, then check your locks, doors, hinges and windows.
- Photograph valuable belongings and keep receipts or serial numbers where possible.
- Tell your insurer if the shed is being used for business or in a way that may differ from ordinary domestic storage.
You may discover that you're already perfectly well covered.
Or you might find that the £4,000 to £5,000 worth of belongings sitting at the bottom of your garden isn't protected quite as comprehensively as you thought.
Either way, it's much better to find out now than after something has happened.
Protect the Building and What's Inside It
A garden shed is often one of the most useful buildings we own, but because it sits outside the main house, it's surprisingly easy to overlook.
The reality is that many sheds contain thousands of pounds worth of belongings. Lawnmowers, bicycles, power tools, garden machinery, furniture and equipment accumulate over the years, often without us ever stopping to calculate their combined value.
Home insurance can provide valuable protection for both sheds and their contents, but policy limits, theft conditions, security requirements and individual-item restrictions can differ significantly between insurers and levels of cover.
So check your policy, understand what you're covered for and make sure your shed is doing its part too.
Keep it maintained, keep it secure and keep a record of what's inside.

Frequently Asked Questions
Is a garden shed covered by home insurance?
Often, yes. A shed may be treated as an outbuilding under buildings insurance, while the belongings inside may fall under contents insurance. The exact level of cover depends on your insurer and policy.
Are the contents of my shed covered by home insurance?
They can be, but some policies place separate limits on items stored in sheds, garages and other outbuildings. Always check your policy wording rather than assuming the same limits apply as inside your home.
Are bikes covered if they are stolen from a shed?
Possibly, but bicycles can be subject to separate limits, security conditions or additional cover requirements. Expensive bikes and e-bikes are particularly worth checking with your insurer.
Does my shed need to be locked for insurance?
Some insurers require sheds and other outbuildings to be locked for theft cover to apply. Check your own policy for specific security conditions.
Can CCTV help improve shed security?
Yes. A visible security camera or video doorbell can act as a deterrent, particularly around driveways, gates and side access. Motion-activated lighting can also make it harder for someone to approach unnoticed.
What should I keep as proof of items stored in my shed?
Photographs, receipts, bank statements, serial numbers and product details can all be useful if you ever need to make an insurance claim or report stolen belongings.
Does insurance cover a leaking or rotten shed?
Insurance is generally intended to cover specific insured events rather than routine wear, deterioration or poor maintenance. Problems such as rot or gradual weather damage may not be covered, so regular shed maintenance remains important.
Is a shed used for business covered by home insurance?
Not necessarily. If you use your shed as a workshop, office, studio or for another business purpose, tell your insurer so they can confirm whether your existing cover remains suitable.
How can I make my shed more secure?
Strong locks, secure hinges, concealed windows, internal anchors, lighting and cameras can all help.
How do I know if I have enough shed insurance?
Calculate roughly how much everything in your shed would cost to replace, then compare that figure with your policy's outbuilding contents limit and any single-item limits.
