Plastic Sheds for Sale

What is on sale right now

Every shed in the grid above has a current Shedstore price below its recommended retail price (RRP). We only list a reduction of 3% to 35%: a tiny cut is not worth calling a deal, and a huge one usually means an inflated "was" price. Prices are pulled from the Shedstore feed every day, so a shed that goes back to full price drops off this page and a new one appears when it is reduced.

When we last checked (November 2026), the reductions fell into three clear groups:

• Palram Canopia: the biggest savings. The Skylight 6x3 and 4x6 were about 25% under RRP, the Rubicon range between 9% and 32% (the 6x8 had the deepest cut), and the Yukon workshops 12% to 16%.
• Shire Tuscany Evo: about 20% off. The two small recycled PVC storage sheds, the Evo 100 and Evo 120.
• Keter: about 5% to 6% off. Every resin shed from the brand on the page. Keter rarely discounts deeply, so a Keter shed sale tends to mean a modest saving across the whole range rather than one big cut.

These are not ex-display or damaged sheds: each one is a current model, delivered new and flat packed, with the full manufacturer warranty. The grid always shows today's price, and the percentage saved is worked out from the RRP in the same feed. Delivery charges and lead times vary by model, so check the Shedstore listing before you order.

Plastic garden sheds for sale compared

Here is every range on this page, with the sizes and specs from the Shedstore listings. Prices are given as bands because they move daily; the grid has the exact figure.

Two things the table shows. First, the biggest percentage cut is not always the best value: a 6% saving on a resin shed with a 15 year warranty can beat 20% off a small PVC unit with a 1 year warranty. Second, check the floor. The Yukon is sold with and without a wood polymer composite (WPC) floor, and the cheaper version sits on a galvanised steel perimeter base, so you need a solid slab under it.

How to tell a real deal from a fake one

A "was" price only means something if the shed was really sold at that price. The guidance on price reduction claims from the Competition and Markets Authority says a "was" price should be a genuine one, and that is the standard we hold the grid to. Before you buy any discounted model, here or elsewhere, run through this:

1. Compare like with like. Plastic shed sizes are rounded. A "6x8" can be 1.85m x 2.28m from one brand and a few centimetres different from another, so compare the metric sizes and the floor area, not the name.
2. Check what is in the box. Floor, shelves, anchor kit and guttering vary by model. A cheaper shed without a floor can cost more once you add one.
3. Read the warranty. Resin and polycarbonate sheds come with anything from 1 to 15 years. The warranty is the brand's own view of how long the panels will last.
4. Look at the price per square metre. Big sheds cost more but often less per square metre: a Rubicon 8x12 works out much cheaper per square metre than a 6x3.
5. Watch for size-for-size swaps. Newton Plus and some Palram models come in mirrored pairs (doors on the gable or on the long side) at the same price. Pick the one that suits the plot, not the one that happens to be reduced.

The best sheds on sale by size

Small sheds under 6x6

For bins, tools and a few cushions, the Palram Canopia Skylight 6x3 and 4x6 are the cheapest sheds here and carry a 10 year warranty. Both have UV-protected panels on an aluminium frame, a skylight apex roof and a Hilti anchoring kit. The 6x3 has double doors; the 4x6 a single door. Shire's Tuscany Evo 100 and 120 are boxier plastic storage sheds in recycled PVC, with a tile-effect roof, lockable doors and a resin tile floor, made to fit against a wall. They are a tidy home for garden tools, bins and outdoor storage of cushions. More options are on our small plastic sheds page.

Mid-size sheds: 6x6 to 8x8

This is the size most UK gardens need: a plastic garden storage shed with room for a mower, tools and two bikes. The Palram Canopia Rubicon 6x8 has had the largest percentage reduction on the page. It has 10mm multi-wall panels, which keep the inside cooler and cut condensation, plus a ramp, wide double doors and an anti-slip floor. The 6x6, 8x6 and 8x8 resin sheds from Keter cost more but come with steel reinforcement, a wood-effect finish, two shelves and a 15 year warranty. Compare the sizes on our 8x6 plastic sheds page.

Large sheds and workshops: 10x8 and up

For a ride-on mower, a workbench or garden furniture over winter, look at the Stronghold, the long Newton Plus sheds and the Palram Canopia Yukon, all in grey. The Stronghold has a steel-reinforced roof, 1.525m double doors and 3-point locking. The Yukon is the biggest building here, up to 11' x 21'3 (3.32m x 6.43m), with commercial-grade 10mm polycarbonate walls, a skylight roof and integral guttering. Our large plastic sheds and heavy duty plastic sheds pages list every model at these sizes.

Keter shed sale: what to expect

Keter is the best-known brand of plastic garden sheds in the UK, and its sheds are among the most searched-for garden storage in the country. On Shedstore the reductions are small but they apply to the whole range: the Factor, Newton Plus, Stronghold and Darwin were all about 5% to 6% below RRP when we checked. On a £1,500 shed that is still around £90.

Keter clearance stock is a different thing: old colours or ranges being sold off. It can be good value, but check that spare parts and the full guarantee still apply. Every model in this Keter shed sale is a current range with its normal warranty, 15 years on the Factor and Newton Plus and 10 on the Stronghold and Darwin. For the whole line-up, including full-price models, see our Keter sheds page, or go straight to the Keter Newton Plus range.

When do plastic sheds go on sale?

Garden buildings, from metal stores to wooden sheds, sell most in spring and early summer, so that is when prices tend to be firmest. Plastic shed deals turn up more often in the quieter months:

• Late autumn and Black Friday. Plastic shed Black Friday offers usually run through late November, with Black Friday itself on 27 November in 2026. It is a sensible time to buy and build before winter weather sets in, with the garden quiet and the ground still workable.
• January. New-year sales clear stock before the spring rush.
• End of season. Late summer is when retailers make room for next year's ranges and clear older models.

You don't need to wait for an event, though. Because this page is built from the live Shedstore feed, it shows whatever is reduced today, in any month.

What to look for in a plastic storage shed

A sale price is only worth having on the right building. These are the features that separate one plastic garden shed from another:

• Roof style. An apex roof (two slopes meeting at a ridge) gives the most headroom in the middle and sheds rain both ways. A pent roof slopes one way, sits lower and fits under a window or against a fence; the Shire Tuscany Evo 100 has a tile-effect pent roof. Most sheds here are apex.
• Floor. A plastic shed with floor included keeps tools and cushions off damp ground. Our sheds with floors page lists only those.
• Doors. Double doors take a mower or bikes; a single door suits a small garden storage shed for tools. Look for lockable doors or a hasp that takes your own padlock.
• Light. A window or a skylight in the roof means you can find things without a torch. The Palram Canopia models have clear roof panels; the Keter ones have windows and a skylight strip.
• Colour. Grey is by far the most common finish, from the dark grey Rubicon and Yukon to the lighter grey Newton Plus and Stronghold. The Keter Factor is beige and the Darwin green.
• Weather. Check the wind and snow ratings for an exposed garden. Shedstore lists 75kg per square metre of snow for the Factor 8x6 and 150kg for the Stronghold 10x8.

Resin, polycarbonate or PVC?

All three are sold as plastic sheds, and all three avoid the yearly painting a timber building needs. They suit slightly different jobs:

• Resin: thick polypropylene panels, often with a wood-grain finish and steel reinforcement. Looks like painted timber, opaque, solid feel. See resin sheds.
• Polycarbonate: tough, UV-protected panels on an aluminium frame, often with skylights, so the inside is bright. Twin and multi-wall versions insulate better than single skin. See Palram Canopia sheds.
• Recycled PVC: box-section panels, good for compact outdoor storage against a wall.

None of them will rot, and none needs treating, so maintenance is a wash with soapy water once a year.

Plastic vs metal and wooden sheds

A metal shed is usually the cheapest for its size, but thin steel dents, drips with condensation and rusts once the coating is scratched. A wooden shed looks traditional and is easy to fix shelves to, but needs treating every year or two and the doors can swell in wet weather. A plastic garden shed costs more than metal and about the same as good wood, and in return needs almost no maintenance: no paint, no rust, no rot. That is why a resin shed with a 10 or 15 year warranty is often the better buy over its life, even before a sale. Our plastic vs wooden shed guide sets out the pros and cons in full.

Before you buy: base, security and planning

A cheap garden shed on a bad base is not a bargain. Plastic garden sheds need a firm, level base, or the panels twist and the doors stop closing. Concrete or paving slabs are best for big sheds; a plastic grid base filled with gravel works for most sizes. See shed bases, and budget for one in the total.

Every model here takes a padlock, which is not included, and the Stronghold adds 3-point locking. Tools are what thieves want from a garden storage shed, so keep power tools out of view of the window. Anchor the shed to its base: the Skylight comes with a Hilti anchoring kit and several Rubicon models with an anchor kit. Our shed security page has alarms and locks for lockable doors, and our shed lighting page has solar lights for winter evenings in the garden.

In England most garden sheds are permitted development, so no planning permission is needed. Within 2m of a boundary the building must be no more than 2.5m high, and it must not cover more than half the garden. The Keter Stronghold is 2.51m to the ridge, so set it a little further from the fence. The Planning Portal guide to outbuildings has the full rules. Your rights if a sale item arrives damaged or faulty are set out by Citizens Advice; Shedstore's own delivery and returns terms are on each product listing.

Plastic sheds for sale: FAQs

What is the cheapest plastic shed for sale here?

The Palram Canopia Skylight 6x3 and 4x6, usually around £330 to £340. For more budget models, including ones not reduced, see cheap plastic sheds.

Is there a Keter shed sale on?

When we last checked, every Keter shed on Shedstore was 5% to 6% below RRP. Keter discounts are usually modest, so a Palram Canopia model is where the bigger percentage savings tend to be.

Do the plastic garden sheds for sale come with a floor?

Most do. The Darwin potting shed listing does not include a floor, and the Palram Canopia Yukon is sold both with a WPC floor and without one. Our plastic sheds with floors page lists only the ones that include it.

How long do plastic sheds last?

A good one lasts many years. The warranty is the best guide: 15 years on the Keter Factor, Newton Plus and Palram Canopia Yukon, 12 on the Rubicon, 10 on the Skylight and Stronghold.
