Why choose a plastic shed
A plastic shed does everything a timber one does, then asks for nothing back. There is no wood to treat, no felt to replace and nothing to rust. The panels are moulded from double-wall HDPE or steel-reinforced plastic. They wipe clean and hold their colour for years. This range covers 91 sheds from Lifetime, Palram and Suncast. For smaller loads see garden storage and storage boxes. Prefer steel? Compare our metal sheds. Brand pages cover Lifetime and 6x4 sheds.
Most plastic sheds come with a built-in floor. That saves you laying a timber base and keeps the contents off the ground. Skylight roofs let daylight in without windows to clean. Wide double doors take a mower straight in.
The mistake we see most is a plastic shed pitched straight onto grass. These sheds need a firm, level base to lock together square. We put ours on paving slabs or a concrete pad every time. Get the base flat and the doors line up perfectly for the next ten years.

Matt's pick
For a first shed, the Palram 4x3 Skylight at £285 is hard to beat. It goes up in an afternoon and needs no base timber. For a family shed we fit the Lifetime 10x8 at £2,190. The double-wall panels feel solid and the floor takes a ride-on mower.
What size shed do I need?
Think about the biggest item first. A 4x3 holds bikes, tools and a mower. A 6x4 adds room for a workbench. An 8x6 and up suits garden furniture over winter. Measure your plot and leave room to walk around the shed.
Getting the base right
A plastic shed needs a firm, level base. Paving slabs, concrete or a plastic grid base all work well. The base should match the shed footprint exactly. A level base is what keeps the doors square and the roof watertight.
What will it cost?
Plastic sheds here start at £285 for a compact store. Larger family sheds run into four figures. Every shed includes free mainland delivery. There are no hidden charges at checkout.
Plastic shed questions
Are plastic sheds any good?
Yes, a good plastic shed lasts for years with no upkeep. The double-wall types are strong and weathertight. They suit anyone who wants storage without the yearly treating a timber shed needs.
Do plastic sheds need a base?
Yes, they need a firm, level base. Paving, concrete or a plastic grid base all work. The base must match the shed footprint for the panels to lock square.
Do plastic sheds come with a floor?
Most models include a built-in floor. It keeps contents off the damp ground. Always check the product page, as a few larger sheds leave the floor open for a slab.
Are plastic sheds secure?
Yes, the doors take a padlock as standard. Steel-reinforced panels resist forcing. For tools and bikes, add a ground anchor inside.
Do plastic sheds get too hot?
They warm up in strong sun like any shed. Skylight and vent panels help air move through. Keep aerosols and paint out of direct heat to be safe.
How long do plastic sheds last?
A quality plastic shed lasts well over ten years. UV-stable HDPE resists fading and cracking. There is no timber to rot, so the structure stays sound.
