Best Plastic Shed UK 2026: Plastic Garden Sheds Compared

Plastic Sheds: A Plain-English Buyer's Guide

Want somewhere dry for the mower, the bike and all those garden tools, without a yearly coat of wood preserver? A plastic shed could be the answer. The best one for you is the shed that fits your space, holds what you need to store and stands on firm, flat ground.

These sheds are made from resin, polycarbonate or PVC, often on a metal frame. They can’t rot, they never need painting and most come with a long maker’s guarantee. That makes a plastic garden shed one of the easiest kinds of all-weather garden and outdoor storage to live with.

Every product on this site is sold by Shedstore, a garden buildings retailer that says it has been trading online for over 24 years. You buy from Shedstore and they look after delivery. You’ll find Keter and Palram Canopia sheds here, plus Shire storage sheds and ProBASE foundation kits to go under them.

Why Choose a Plastic Garden Shed

A plastic garden shed suits anyone who wants tidy, dry outdoor garden storage that’s close to maintenance-free. A wet British winter is less of a worry, because the walls can’t soak up water. The colour runs right through them too, so there’s nothing to paint.

Low maintenance. A wash with warm soapy water now and then is all most of them need.
Weather resistant. Most are UV protected, so they won’t fade fast in the sun.
Long guarantees. The big makers back most of their sheds for 10 to 15 years.
Lockable doors. Nearly every shed here takes your own padlock.
Plenty of sizes. Choose anything from a slim tool shed to a big garden storage shed you can work in.

There are a few things to know before you buy, though.

It must stand on flat, firm ground and be fixed down, so it can’t shift in strong wind.
You can’t screw hooks in just anywhere, so the maker’s own shelf kits work best.
Some sheds show a little condensation on cold mornings, which good ventilation helps with.

Plastic, Wooden or Metal?

A plastic storage shed sits between wood and metal. Unlike a wooden shed it needs no yearly treatment. Unlike a thin metal shed it won’t rust. A wooden garden shed is easier to fix things to and to change later, while a heavy duty metal shed can be harder to break into. If low maintenance matters most, plastic is hard to beat. Our plastic vs wooden shed guide goes into more detail.

	Plastic	Wooden	Metal
Looking after it	Almost maintenance-free	Regular wood treatment	Touch up any scratches
Weather damage	Weather resistant	Can rot if left untreated	Can rust where scratched
Hanging things up	Maker’s kits fit best	Screw in almost anywhere	Maker’s kits or brackets
Look	Wood effect or plain grey	Natural wood	Painted metal

What Resin Sheds Are Made Of

Not all plastic is the same. Keter makes most of its resin sheds from Evotech, a resin with a wood effect finish. Several of its ranges add steel reinforcement for extra strength. The Darwin uses fade-resistant, all-weather Evotech with reinforced aluminium connectors.

Palram Canopia builds its sheds from polycarbonate on an aluminium frame. The Rubicon and Yukon have 10mm thick walls. Many Palram Canopia sheds have a skylight roof that lets daylight in but stays opaque from outside, so passers-by can’t easily see in. Shire’s Tuscany Evo is different again, with box-section walls made from recycled PVC.

So which suits you? If you like the look of wood without the work, a wood effect resin storage shed could be the one. Browse our resin sheds. If you want light inside for potting or a hobby, a polycarbonate skylight shed is worth a look.

Sizes and Where to Put It

Sizes are given in feet, width first, so a 10x8 is about 10ft wide and 8ft deep. The outside size is a little bigger than the floor inside, so check both on the product page. Measure your outdoor space, then leave room to open the door and to walk round it while you build.

Small garden storage sheds make a handy tool shed for a strimmer and garden equipment in a tight spot.
6x4 sheds are a handy size for a small mower and tool storage.
6x6 and 7x7 sheds are square, so they suit a corner of the garden.
8x6 plastic sheds give room for bikes, a mower and garden chairs.
8x8 sheds add depth for bigger equipment and a space to stand.
6x10 and 6x12 sheds are long and slim, so they fit down the side of a house.
10x8 sheds give big storage with space to work.
Large storage sheds start at around 90 sq ft for a lot of kit.

Where you put it matters as much as the size. Pick the flattest spot you have, with room round the sides to build and clean. Keep it clear of overhanging branches. And think about the walk. If you’ll be in and out every day, a garden storage shed near the back door or the patio is easier to live with.

Keter, Palram Canopia and Shire

Keter sheds are wood effect resin, mostly in grey or beige. The Factor apex sheds we list run from 6x6 up to 8x11. The Newton Plus comes as an apex shed or a reverse apex. You choose where its entrance and windows go as you build it. The Stronghold is an apex shed with six windows and lockable doors. Most sizes add a skylight too. Its strengthened roof is rated for a snow load of up to 150kg per square metre. And the green Keter Darwin is a potting shed with seven windows, five of which open.

Palram Canopia sheds come in grey or tan. Most of the ones we list are apex sheds. The Skylight and Voyager ranges start at the lowest prices. The Rubicon has thick, durable multi-wall polycarbonate and lockable doors, with a ramp on many sizes. The Yukon is the widest, at 11ft. Shire’s Tuscany Evo sheds are compact garden storage sheds in white and buff, made for tool storage and small kit.

You may also see Suncast, Lifetime, Duramax and Outsunny sheds at other shops, along with Keter’s Signature, Manor and Cortina ranges. We only list what Shedstore sells, so you won’t find those here.

What to Look For

Floor. Some sheds include a floor, some sell it separately and some stand straight on a slab. Looking for a plastic shed with floor included? Stick to our sheds with floors.
Roof. An apex roof gives more headroom in the middle. A pent roof is lower at the back and suits a fence line.
Doors. A double door makes it easier to get a mower or bikes in and out. A ramp helps with anything on wheels, which is why our plastic bike sheds often have one.
Windows. A window or a skylight helps if you’ll work inside. A plastic potting shed such as the Darwin adds extra windows.
Ventilation. Vents let damp air out and help keep condensation down.
Wind and snow. Many makers give wind and snow load ratings. You’ll find them on the product page where the maker gives them.
Locks. Look for lockable doors or a padlock fixing.
Guarantee. Check the maker’s guarantee on each product page.

Choosing a Foundation

Every resin or plastic garden shed needs a firm, flat base. A concrete pad, paving slabs or a flat patio all work well. A plastic foundation kit is quicker to lay, though. ProBASE grids are made from 100% recycled plastic and lock together over a weed membrane. You fill them with pea gravel (not included). The open grid lets rainwater drain away and air move under the floor. If you ever move the shed, you can lift the grids and use them again.

Got a slope, or old slabs that aren’t quite true? Adjustable shed bases such as ProBASE QuickJACK are made for that job, with kits for hard surfaces and for soft ground. Choose one that’s slightly larger than your shed. We list bases for 6x4, 8ft x 6ft and 10x8 sheds.

Outdoor Storage Boxes and Bin Stores

Not everyone needs a walk-in shed. A slim plastic garden storage shed like the Shire Tuscany Evo holds tools and long-handled kit in a small footprint. Plastic garden storage boxes from Keter keep cushions, toys and barbecue bits tidy under a lift-up lid, in brown or anthracite. And wheelie bin stores tidy your bins away behind a lid and double doors.

These outdoor storage boxes and units suit patios and small gardens where a full shed won’t fit. They make good outdoor garden storage next to a bigger shed too, for the things you reach for every day.

Kit Out Your Shed

Once it’s up, a few extras make any garden shed much easier to use. Shed shelving keeps pots and tins off the floor. Solar shed lighting gives you light on winter evenings with no cable to run. A padlock or a wireless alarm from our shed locks and alarms range adds peace of mind, since most sheds come padlock ready but without the padlock.

Putting It Together

Most resin sheds arrive flat-packed for you to build. Allow a day and a second pair of hands. Build on a calm, dry day, with the parts laid out on a sheet so nothing gets lost in the grass. Then fix it down as the maker shows, so it stays put when the wind picks up.

Apex or Pent Roof?

An apex roof has a ridge in the middle, so an apex shed gives you the most headroom where you stand. A pent roof slopes one way, so a pent shed sits lower at the back and fits neatly against a fence or wall. A reverse apex puts the entrance on the long side, which makes the back of a long shed easier to reach. Pick an apex shed for one you’ll walk into often and a pent roof for a tight spot.

Delivery and Returns from Shedstore

Shedstore offers free standard delivery on most items to mainland UK (Shedstore’s terms apply). Some remote postcodes pay extra. Many sheds are sent by the maker, so there’s often a lead time before delivery and the maker gets in touch to book a date. Delivery is to the kerbside or your driveway. You have 14 days from delivery to cancel, but the maker’s collection charge comes off your refund.

Do I Need Planning Permission?

In England most garden sheds don’t need planning permission, thanks to permitted development rules. That holds as long as the shed sits behind the house and covers no more than half the garden. Within 2m of a boundary it must be no higher than 2.5m. Rules differ for listed buildings, flats and protected areas. They also differ in Wales, Scotland and Northern Ireland. Check with your local council if you are not sure.

Questions Buyers Ask

Are plastic sheds any good?

Yes, for most gardens they are. There’s no rot to worry about, no painting to do and most makers back them for years. The sturdier ones have a metal frame or metal reinforcement, which helps make them durable and long lasting. Put yours on firm, flat ground and fix it down as the maker shows. Then it should keep your kit dry for years.

Do plastic sheds need a base?

Yes, every shed needs a firm, flat base it can be fixed to. The Palram Canopia Rubicon must be anchored to a solid level base. The Keter Factor should sit on concrete or paving. A plastic grid foundation kit is a quicker choice than laying a slab.

How long do plastic sheds last?

The maker’s guarantee is the best guide we have. Keter gives 15 years on its Factor and Newton Plus sheds and 10 years on the Stronghold. Palram Canopia gives 12 years on the Rubicon and 15 years on the Yukon. Flat ground and a wash now and then help it last its full lifetime.

Is a plastic garden shed better than wood or metal?

It depends on what matters most to you. Plastic needs the least maintenance. Wood is the easiest to fix shelves into and to change later. Metal can be a good choice if keeping thieves out comes first. Compare them in our guide to plastic and wooden sheds.

Do plastic sheds get condensation?

They can, like most garden buildings. On a cold morning, damp air inside can settle as droplets under the roof. Good ventilation is the answer. Pick a shed with a vent or two (the Factor comes with air vents) and stand it on an open grid that lets air move underneath. Try not to put wet tools or damp cushions away.

Do plastic storage sheds get hot inside?

On a sunny day they can get warm inside, as any shed can. A skylight roof lets in daylight, which is handy for working but adds a little warmth too. Prop the door open on hot days. Keep anything that hates heat, such as paint, in the coolest corner.

Can you lock a plastic shed?

Most have lockable doors, but you’ll need to buy the padlock. The doors on nearly every shed we list are padlock ready. The Keter Stronghold’s lockable doors go further, with a 3-point locking system. A strong padlock and a battery alarm from our shed security range add peace of mind.

Do plastic sheds come with a floor?

Many do, so finding a plastic shed with floor included is easy. Keter’s Factor, Newton Plus and Stronghold sheds all include a floor. Palram Canopia’s Skylight and Rubicon sheds include one too. Some Yukon sheds come with a galvanised perimeter frame instead, so check the floor line on each product page. Every one of our plastic sheds with floors comes with one.

Are resin sheds easy to put up?

Most are a one-day job for two people with basic tools. The 8ft x 6ft Keter Factor takes two people about 4.5 hours, with no cutting or sawing. Get the ground flat first, because a twisted frame makes the doors hard to line up. Then follow the maker’s steps for fixing it down.

Are plastic sheds waterproof?

Yes, they’re made to be weatherproof and to keep the rain out. The walls don’t soak up water like wood. Many roofs are shaped to run rainwater off too. The Palram Canopia Yukon even has built-in guttering. Flat ground matters here too, since a twisted frame can open small gaps at the joints.

Is delivery free?

For most things, yes. Standard delivery to mainland UK is free on most of Shedstore’s range, under Shedstore’s own terms, with a charge for a few remote areas. Many sheds come straight from the maker, so allow for a lead time. Pop your postcode into the delivery section on the Shedstore product page to see the details.
