A single garden theft claim cost over £14,000 last year, according to Allianz. That figure alone is higher than what most standard home insurance policies would pay out for all your garden contents combined. For a typical UK policy, garden cover tops out between £1,000 and £10,000, and individual items are usually capped at roughly £2,000 each. If you own a decent barbecue, a lawnmower, some garden furniture, and a bike, you can hit those limits faster than you might expect.

Most people assume their home insurance automatically covers everything in the garden. It doesn’t. You need both buildings and contents cover to get full protection for outdoor spaces, and even then, the limits and exclusions catch plenty of people off guard. The gap between what people think is covered and what actually is covered can cost thousands. Here’s what you actually need to know.
The most important concept to grasp here is the single-item limit. This is the maximum your insurer will pay for any one stolen or damaged item, regardless of what it actually cost you. If that limit is £2,000 and your bike was £3,000, you’re £1,000 out of pocket.
What I tend to notice is that people rarely check this number until after something goes missing. It’s worth weighing the value of your most expensive garden items against that cap before you need to claim.
Cover limits, single-item caps, and what they mean for your outdoor belongings
Garden cover under a standard home insurance policy splits into two distinct categories, each with different limits. The table below shows how buildings and contents insurance divide the responsibility — and where the typical caps sit.

| Insurance Type | Garden Items Covered | Typical Limit |
|---|---|---|
| Buildings insurance | Sheds, greenhouses, summerhouses, gazebos, fences, walls, gates, drives, patios, decking, built-in pools and hot tubs, oil/septic tanks | Part of buildings sum insured — varies by policy |
| Contents insurance | Garden furniture, BBQs and pizza ovens, lawn mowers, strimmers, power tools, plant pots, ornaments, trampolines, goal posts, patio heaters, security lights, outdoor speakers | £1,000 – £10,000 total |
| Single-item cap | Any individual item claimed under contents cover | ~£2,000 per item |
Say your garden holds a lawnmower (£500), a gas BBQ (£1,200), a bike (£2,500), and a set of rattan furniture (£1,800). Total value: £6,000. If all of it is stolen, your contents policy’s garden sub-limit might be capped at £5,000 — and the bike alone exceeds the single-item cap, meaning you’d only get £2,000 for it, not the £2,500 you paid. You’d end up roughly £1,500 short on the overall claim.
The gaps that cost you money — common garden insurance mistakes
Assuming contents insurance automatically covers the garden
Many policies limit garden contents to a sub-section of your overall contents cover. That £1,000–£10,000 cap is often separate from what you’d claim for indoor belongings. If your home contents limit is £50,000 but the garden sub-limit is only £2,000, you can’t move money from one to the other. The fix is simple: read your policy schedule for the “garden” or “outdoor” sub-limit, not the total contents sum.
Not disclosing outbuildings at purchase
A shed or greenhouse is covered under buildings insurance, but only if the insurer knows it exists. If you install a new garden room or summerhouse and don’t tell your insurer, the structure and anything stored in it could be excluded from a claim. The process is straightforward: call your insurer or log into your online account and update your buildings details. Do it as soon as the structure is built.
Leaving items unsecured and expecting a payout
Insurers will reject claims if items were stolen from an unlocked shed or left visible from the road overnight. “Reasonable care” is standard policy language. If you leave your bike unlocked in the garden and it’s gone in the morning, you’re unlikely to be covered. A simple padlock on the shed and a smart lock on the gate goes a long way toward satisfying that condition.
Not documenting high-value items
If you can’t prove you owned a £2,000 BBQ or a £1,500 set of garden tools, the insurer has no obligation to pay out. Take photos of each item, keep receipts, and store them digitally. Do this once and update it when you buy something new. It takes 15 minutes and can save you an argument at claim time.
- Check your garden contents sub-limit — it’s separate from your main contents cover
- Confirm all outbuildings are declared on your buildings insurance
- Secure sheds, gates, and any moveable items with locks and alarms
- Photograph and list every garden item worth over £500
- Review single-item caps against your most valuable possessions
How to make sure your garden is properly covered — a practical walkthrough
Check what your current policy actually says about outdoor spaces
Don’t rely on what you think is covered. Pull up your policy documents and look for the words “garden”, “outdoor”, or “contents away from the home”. Note three numbers: the total garden contents sub-limit, the single-item limit, and the buildings sum insured for outbuildings. If any of these numbers is blank or vague, call your insurer for written confirmation. What I’d do here is also note the renewal date — if the limits look too low, you can shop around at renewal rather than mid-term.
Disclose every outbuilding — including the one you built last summer
If your garden has a shed, greenhouse, summerhouse, garden office, or even a permanent gazebo, it needs to be on your buildings insurance. The same goes for built-in features like a swimming pool, hot tub, or outdoor kitchen. If you built it after the policy started, you’ve got an update to make. Most insurers let you do this online in under five minutes. If you’re unsure whether something counts as an outbuilding, err on the side of telling them — it won’t raise your premium much, but not telling them can void a claim entirely.
Secure your garden and document your belongings
Insurers take garden security seriously. Visible deterrents improve your chances of a smooth claim. A video doorbell covering the garden gate, a smart alarm for the shed, and a motion-activated light are all practical steps that cost less than a single uninsured loss. Beyond security, keep a running inventory of garden items worth over £500. Photograph each one against a neutral background and store the images in a cloud folder or a small safe indoors. This documentation is what the insurer will ask for before they pay out.
- 1Find your garden sub-limitsLocate the garden contents cap and single-item limit in your policy schedule. Write them down.
- 2List every garden item worth over £500Include the make, model, estimated value, and purchase date. Add photos and receipts.
- 3Check your outbuildings are declaredLog into your insurer’s portal and confirm every shed, greenhouse, and garden room is listed under buildings cover.
- 4Upgrade garden securityInstall locks, a video doorbell, a smart alarm, and motion-sensitive lights. Keep photos of the upgraded security setup.
- 5Consider separate cover for high-value itemsIf any single item exceeds the £2,000 cap, ask your insurer about specifying it separately on the policy.
What’s changing — upcoming factors that affect garden cover
The home insurance market is seeing higher claim volumes for weather-related garden damage, and some insurers are tightening their exclusions around extreme weather. If storms are forecast, you’re expected to secure or bring in moveable items. Policies are also getting more specific about what counts as an “outbuilding” — a garden room with electricity and insulation may be treated differently from a basic shed. When you renew, check whether your insurer has updated its definition. The rules shift more often than most people realise.

The one thing most people overlook about garden cover
The single most overlooked detail in garden insurance isn’t the total cover limit — it’s the single-item cap. That £2,000 threshold hasn’t moved much in years, but the price of garden furniture, BBQs, and bikes has climbed steadily. A policy that looked adequate five years ago may now leave you thousands of pounds short. The fix isn’t complicated: check the cap, compare it against your actual belongings, and either specify high-value items or adjust your cover. Do it before you need to claim, not after.
