Cheapest Sheds of 2026

Finding the cheapest shed comes down to four things: size, material, roof style and the base you stand it on. Whether you want a small metal shed for a mower, a classic wooden shed for tools and bikes, or a wide workshop shed with a window, the right one suits your plot and your budget without wasting money.

At Cheapest Sheds we compare hundreds of garden buildings from leading UK retailers — including Shire, Forest Garden, Mercia, Rowlinson, Yardmaster and Keter — so you can see every price side by side and buy the cheapest one fast.

Why Buy a Garden Shed?

A garden shed pays for itself the first winter. Tools stop rusting in the rain, the mower comes out of the hallway and bikes get a dry home with a lock on the door. Most families fill a 6x4 within a month, which is why the next size up is usually money well spent.

There is a plain financial gain too. A cluttered garage swallows a parking space worth far more than the shed cost. A cheap wooden shed with a decent felt roof frees that up for a few hundred pounds. It is the simplest way to add dry storage to a house.

Shed Sizes Explained

Sheds are quoted as width x depth in feet. Width runs across the front where the door sits, depth is how far back it goes. Here are the sizes that cover most UK gardens:

4x3 and 5x3 sheds — narrow storage for a mower, tools and a strimmer down the side of a house. From around £150.
6x4 sheds — the best-selling size in Britain. Room for a mower, wheelbarrow and hand tools. From around £220.
8x6 sheds — the safer choice for most families, with space for bikes and a small bench. From around £450.
10x8 sheds — suits a workshop, a potting bench or garden furniture stored over winter. From around £900.
12x8 and wider — workshop sheds with double doors and extra windows. From around £1,300.

What to Look for When Buying a Cheap Shed

Two sheds at the same size and price can behave very differently after a wet winter. These are the specifications worth comparing:

Cladding — overlap is cheapest and fine for storage. Shiplap sheds shed water better. Tongue and groove is thickest and stays tight for longest.
Timber treatment — pressure-treated timber carries a 10 or 15 year anti-rot guarantee. Dip-treated wood costs less but wants a coat of preservative every year.
Floor — check the floor is included and look at the bearer spacing. Solid sheet floors on close bearers take a mower without flexing.
Roof — apex roofs give headroom in the middle, pent roofs suit a fence line. Look for felt shingles or EPDM over plain mineral felt.
Security — a hasp and staple with a closed-shackle padlock beats the supplied catch. Windowless models give thieves nothing to look at.
Guarantee — ten years against rot is the benchmark on treated timber. Metal and plastic sheds usually carry 10 to 15 years.

Shed Styles: Apex, Pent and Corner

Three shapes cover nearly every UK garden. An apex shed has a ridge down the middle, which gives standing headroom and throws rain off both sides. It is the shape most people picture when they think of a shed.

A pent shed slopes one way only, so it tucks against a fence or a wall and stays under the 2.5m boundary limit easily. A corner shed takes a five-sided footprint and fills a dead corner that nothing else fits.

Free UK Delivery on Cheap Sheds

Most retailers we compare offer free UK mainland delivery on sheds as standard, which matters when a flat pack weighs 200kg. Typical lead times run from 3 to 21 days, with the courier ringing ahead to book a day. Check the product page for your postcode, as parts of Scotland, Northern Ireland and the islands carry a surcharge.

Sheds arrive as panels with fixings and instructions. Allow two to four hours for a 6x4 shed with two people; a 10x8 takes most of a day. Always level the base first, since a twisted floor stops the door shutting for good.

Sheds & Planning Permission

A garden shed normally counts as permitted development and does not require planning permission, so long as it stays within the usual limits for outbuildings: under 2.5m high within 2m of a boundary, no more than half the garden covered, single storey and not sited forward of the house. Listed buildings and homes in conservation areas or national parks follow tighter rules — ask your local planning authority before you order.
