31 cheap sheds from trusted UK retailers
Our cheap 6x4 sheds are the classic first garden shed: big enough for a lawnmower, garden tools and a bike, small enough for most back gardens. Prices start at around £215 for a Yardmaster metal shed, with pressure treated Forest Garden 4Life and Beckwood timber from about £330 and Palram Canopia plastic sheds with skylight roofs. Choose apex, reverse apex or pent roofs, single or double doors, with windows or windowless. Every one is sold by Shedstore. If you need a little more room, compare our cheap 7x5 sheds, or go smaller with cheap small sheds.
Six by four is the most popular garden storage size in the UK for good reason. The wooden ones here measure 1.83m x 1.18m at the base, about 2.15 square metres of floor, and stand 2.02m to 2.25m tall, so most adults can stand up inside. That's room for:
It won't swallow a ride-on mower, a workbench and two bikes at once. If that's the plan, a cheap 8x6 shed gives almost twice the floor for not much more.
Here's how the ranges on this page line up, using Shedstore's own specs. Base sizes are the footprint; the roof overhang adds a few centimetres. Prices change daily, so check the cards above for today's figure.

The cheapest 6x4 outright is the Yardmaster metal one, but it's shorter and has no floor. The best value wooden pick is the 4Life overlap at around £330, and the Beckwood shiplap costs roughly £90 to £130 more for thicker walls, framing and floor.
Most of our range is Forest Garden timber, and all of it is pressure treated: the preservative is forced deep into the wood at the factory, which is why Forest gives a 25 year anti-rot guarantee and you never need to re-treat it. Cheaper dip treated sheds are only coated on the surface and need a coat of preservative every year or two, so pressure treated timber usually costs less over its life. Wood is also easy to fit with hooks, shelves and a light. See all our cheap wooden sheds for other sizes.
The two Yardmaster garden buildings are hot-dipped galvanised steel with a 15 year anti-rust guarantee and no maintenance at all. Sliding double doors give an opening of around 800mm, wide enough for a mower or a bike. The catch: no floor is included, so you need a solid base, and at 1.74m (Castleton) or 1.84m (Platinum) tall you'll stoop at the edges. Allow four to six hours to build one. More choice on our cheap metal sheds page.
The Palram Canopia Skylight is a 4ft x 6ft polycarbonate garden building on an aluminium frame, with a built-in anti-slip floor and roof panels that let daylight in while hiding what's inside. It needs nothing but a wash now and then, and carries a 10 year guarantee. You can't screw shelves anywhere you like into plastic, so plan storage first. Compare our cheap plastic sheds.
Forest builds the same 6x4 garden shed shapes in two qualities, and that explains most of the price gap on this page.
For tools and a hose, overlap does the job. If it will guard a mower and bikes, or sits somewhere exposed, the shiplap is worth the extra. Our shiplap sheds page has the bigger Beckwood sizes.
The roof decides where the door goes, and on a 6x4 that matters.
See more shapes and sizes on our apex sheds and pent sheds pages.
The floor will take one, but check the door first. A single door here is 590mm wide. A compact electric mower, usually around 40cm across, goes through easily; most adult bikes have handlebars 60cm to 80cm wide, so you'd have to turn them to get them in. If you'll wheel things in and out every week, pick a double door model: the Forest double door sheds open to 1,090mm and the Yardmaster sliding doors to around 800mm. The Palram's single door is 660mm. More two-door options on our double door sheds page.
A window lets you see to find things without a light. Going windowless hides your mower and bikes from passers-by and gives you more wall for hooks and shelves. Most 6x4 designs here come both ways for about the same price.
For security, every Forest door has hidden hinges that can't be unscrewed from outside. The 4Life sheds lock with a hasp and staple, the Beckwood and Palram ones with a pad bolt, the Yardmaster ones with pad-lockable handles and anti-tamper bolts. None comes with a padlock as standard, so budget for a decent closed-shackle one, and fit a ground anchor inside if bikes live there.
Every one needs a firm, level base, and none come with it, so add it to the price. For the wooden sheds, a few paving slabs or a gravel-filled plastic grid base is the cheapest way; the Forest floors sit on pressure treated bearers that keep them off the ground. The metal and plastic sheds are best on concrete or slabs because they need screwing down against the wind. Make the base the size of the footprint, not the roof overhang, about 1.83m x 1.18m for the wooden ones.
A 6x4 wooden shed is a two-person job most people finish in a day once the base is ready. Shedstore offers free delivery to most UK mainland postcodes. The Forest Garden website has assembly guides for its sheds and Palram Canopia's UK site covers its plastic ones.
Almost never. In England a garden shed is permitted development if it's single storey, isn't in front of the house and doesn't cover more than half the garden. Within 2m of a boundary it can be no more than 2.5m tall (Planning Portal outbuildings rules). The tallest model here is 2.25m, so any of them can go right against your fence. Listed buildings, conservation areas and National Parks have tighter rules; the government's permitted development guidance has the detail.
Pressure treated wood needs no preservative, so maintenance is light: stain or paint it if you like the look, sweep leaves off the roof, keep soil and plants away from the walls and check the felt each spring. Leave a small gap at the back so the back wall dries out. Metal and polycarbonate models are low maintenance: a wash once a year and a check that the fixings are tight.
The Yardmaster Castleton metal shed, at around £215. The cheapest wooden 6x4 shed is the Forest 4Life overlap, with or without a window, at around £330.
The ones we list are. Every wooden model is pressure treated with 25 years of rot cover, the metal ones have 15 years against rust and the plastic ones 10 years. Budget garden buildings earn a bad name from thin, dip treated timber and chipboard floors.
Pressure treated wooden sheds are guaranteed against rot for 25 years, and with a good base and a sound roof they should outlast that. Galvanised steel models carry 15 years against rust.
Yes. Without a level base the doors stick, the floor bows and the timber rots. Paving slabs or a plastic grid are fine for wood; steel and polycarbonate ones should be fixed to concrete or slabs.
Yes, for most push and electric mowers, with room left for tools on the walls. Check the mower's width against the 590mm single door, or choose a double door design.
