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
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
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 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
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 Boxer 5’x2′ Metal Storage Box
Another compact metal storage box option is the Boxer. It’s made from hot‑dipped galvanised steel panels with a zinc and epoxy coating for rust and corrosion protection.
The lid uses a hydraulic mechanism so it stays open while you load tools in and falls closed to keep the contents safe from the weather. There’s a latch on the front where you can add a padlock for peace of mind (padlock not included).
Low to the ground, it fits neatly against a wall or in a corner. Assembly is straightforward with included fixings and instructions.
Other models are available; a few go over £300, but the quality makes them worthwhile (even if they’re in the ‘cheap’ range):
