Our Best Garden Sheds & Storage Boxes Under £300

Here we have our best garden storage solutions that won’t stretch your budget. Most are small to medium in size, but you still get something that lasts.

BillyOh Switch Overlap Pent Shed

BillyOh Switch Overlap Pent Shed

At this price point, you can get the 4×4 version – windowless, with floor bearers included. It’s a compact model that still gives you plenty of usable space inside.

The tongue and groove floorboards are sturdy enough to support heavy equipment. Wall storage? Absolutely. Wall shelves can be attached to the sturdy 28x28mm framing. You can even choose which side the wide double doors go on, thanks to its modular design.

Every detail is built with quality and security in mind, matching what you’d find from pricier brands. Check it out to see how it’s put together.

BillyOh Mini Keeper Overlap Pent Store Shed

BillyOh Mini Keeper Overlap Pent Store Shed

Sheds can hold almost anything, but it’s always great to have one built for a specific purpose. The Mini Keeper handles bikes best if that’s what you need.

If you look at it, it’s lower than standard units in terms of height, but tall enough to store your bike upright in a 6×3 size. The pent roof helps with that, giving ample headroom, while also helping with drainage.

Depending on your bike’s size, it can still accommodate tools in the corners. The back of the double doors can hold hooks, suitable for helmets.

Extras are available, and even with one added, it stays below £300.

BillyOh Portland Apex Metal Shed Including Foundation Kit

BillyOh Portland Apex Metal Shed Including Foundation Kit

The Portland Apex is packed with features you won’t usually get in cheaper metal sheds.

To start, it’s constructed using tough galvanised steel with a modern grey finish. Pair that with a steel foundation kit for stability and support. This makes the shed durable in harsh weather and against corrosion year-round.

It’s windowless for privacy, yet the interior feels spacious at 7×6. Sliding double doors create a wide entrance and can be secured with a shed padlock.

One of the largest models on this list, and the price is hard to beat. What’s not to love?

BillyOh Flexi Pop Up Portable Fabric Shed

BillyOh Flexi Pop Up Portable Fabric Shed

If you’re not ready to commit to a permanent garden building, this is the perfect in-between. Made from steel and polyethene, which guarantees it holds up to outdoor conditions. It’s simple to set up, like a tent with a roll-up door, and do us whenever you need it. And you have a temporary storage space.

Tip: Store tools or equipment in containers or boxes to protect them from dust and moisture. If you’re storing a bike, park it inside, but use a rack or stand to keep it upright and organised.

Lifetime 500l Large Cushion Box Dark Grey

Lifetime 500l Large Cushion Box Dark Grey

An outdoor storage doesn’t have to be a shed to get the job done—a large box can be just as effective. Take the Lifetime, for instance. At 5ft wide with a 500L capacity, it’s perfect for garden furniture cushions or children’s outdoor toys.

Made from high-density polyethene and reinforced with powder-coated stainless steel hardware. Tough enough for outdoor use, it handles exposure to the elements. There’s also a controlled spring-hinge lid that keeps contents safe and dry.

This storage box is safe to be placed near a swimming pool, on a patio, or on open decking.

BillyOh Swindon Plastic Garden Storage Box Grey

BillyOh Swindon Plastic Garden Storage Box Grey

A plastic mode is also available, and that’s the Swindon. Made from durable PP wall panels and reinforced with hot-dipped galvanised steel tubes. It has a sleek design that doesn’t immediately look like a plastic storage box.

The lid includes an internal mesh pocket for smaller items. Inside, the main compartment gives more room for your belongings. UV-treated for anti-fade protection, this 5x2ft box requires minimal upkeep. A safety lock system to boot, for peace of mind (padlock sold separately).
