Yes. All of our plastic sheds come with a paper booklet of assembly instructions included in the box, to ensure the assembly process goes as smoothly as possible, and construction should be completed within a few hours with two people on the job.
No. Our plastic sheds are made from fire-retardant plastic, which may offer some protection, but aren't entirely fire-resistant, so the correct precautions should be taken to ensure that no naked flames are left in the presence of the building.
Yes, they're recyclable and good for the environment. Once you're done with your plastic shed, check with your local recycling plant for instructions on how to dispose of it.
For the most part, no, you shouldn't need planning permission, although there are certain rules you have to abide by. The main ones are that your shed shouldn't be in the front garden, shouldn't be over 2.5m tall, and should leave at least half the original outdoor space remaining without buildings. Some properties are subject to tighter restrictions. Check with your local council if you're not sure.
Yes, as concrete can act as a base for the shed. Units that feature a foundation kit can be anchored directly into concrete for extra support.
As with all of our products, we offer a ten-year guarantee against rot and decay. Plastic, though, is a highly durable material and does not decompose easily. Our plastic sheds should last at least this long if treated well.
Most of our plastic sheds feature built-in vents, which help to reduce internal humidity and prevent the buildup of moisture. While plastic sheds are not immune to damp, they will not rot. You can help reduce the internal moisture further by keeping wet items out and being careful about the storage of plants.
Yes. A plastic shed requires a base surface to sit on. The base must be solid, level, and should not allow water to pool around it. While the plastic won't soak up water, you don't want it tipping.
For a base, you can use decking, your patio, paving slabs, a concrete slab, or a prefab base kit.
Why choose a plastic garden shed?
If you want maintenance-free garden storage, plastic sheds are hard to beat. Resin and vinyl cladding won’t absorb moisture, so there’s no rot to treat and no flaking paint. Panels are UV-stabilised to help resist fading and brittleness, while steel or composite reinforcements add rigidity for everyday use.
Storage first: match the shed to your items
Plastic models excel as general garden storage — think lawnmowers, pressure washers, cushions, bikes, and bins. Measure your bulkiest item and compare to the door opening width/height. For bikes or wheelbarrows, look for double doors and low thresholds. Shelving kits or internal hooks can help organise tools and smaller gear.
Floor vs foundation kit: what’s the difference?
- With floor: The shed includes an integrated floor panel that helps keep contents off the ground. You still need a flat, solid, level base beneath it.
- With foundation kit: You’ll receive a metal framework to fix to either anchor into your base (e.g. filling it with concrete), which turns the shed into a more permanent fixture. Alternatively you could fill it with gravel or simply lay your own floor surface over the top.
Whichever you choose, just be sure to install somewhere water can't pool.
Building the right base and anchoring
Aim for a flat, level platform of concrete, paving slabs, or a well-constructed timber frame. Follow the manual for anchor points and the correct fixings (e.g., expansion bolts for concrete). Anchoring reduces movement in high winds and helps maintain tight panel joints.
Key plastic shed features to compare
- Cladding: Double-wall or ribbed resin/vinyl panels balance strength and weight.
- Reinforcement: Look for steel-supported frames or trusses on larger sizes.
- UV stability: UV-treated panels help resist discolouration.
- Roof design: Apex and pent roofs both shed rain; skylights or translucent roof sections add daylight.
- Ventilation: Integrated vents improve airflow and help manage condensation.
- Doors & hardware: Check hinge type, threshold height, and padlock-ready fittings.
- Small plastic sheds (4×3, 4×6): Tools, cushions, recycling, kids’ kit.
- Medium plastic sheds (6×4, 6×8): Bikes, mower, BBQs, seasonal storage.
- Large plastic sheds (8×6, 10×8+): Multiple bikes, bulky equipment, family storage overflow.
- Do you prefer an included floor for simplicity, or a foundation kit for a more permanent shed?
- Is your base flat, firm, and level?
- Do the door opening and internal headroom fit your items?
- Do you need double doors, skylights, or shelving?
Easy Assembly Plastic Sheds
Plastic sheds are designed for straightforward, bolt-together assembly with interlocking panels. Two adults can typically complete installation with basic tools. A level base is the single biggest factor for an easy build and a long-lasting result.
Low maintenance sheds
There’s no painting or staining. Keep doors and vents clear, and give the exterior an occasional wash with mild soapy water. Periodically check anchors and screws for tightness.
Security & ventilation best practice
Some of these plastic sheds include a Fit a weatherproof padlock to the supplied hasp or padbolt. Keep vents unobstructed, and allow wet gear to dry before storage. In high-humidity areas, consider a small desiccant or free-standing rack to improve airflow around items.
