The best metal garden sheds, compared.
Top pick: YODOLLA metal storage cabinet Best value: COZYBRITE 8 x 6 metal shed – Highest value part among the rest, 5, at about £239.99, with 3.6 from 25 reviews and room a reviewer uses for a disability scooter. Updated 22.10.2026.
A metal garden shed is a flat-pack steel building: coated or galvanised sheet on a steel frame, with a pent or apex roof and hinged or sliding doors. In the UK you use one for tools, a mower, bins, a bike or a scooter. Expect thin sheet, a two-person build, and a listing that sometimes disagrees with itself. You recognise a suitable shed by a centimetre size that matches the title, a door you can measure, and an honest description of the floor. A floor frame is not floor boards. Look for vents, because condensation on cold steel looks like a leak, and for a bolt-down rather than pegs on a concrete pad. Security is a hasp and where the screws sit. In England a metal outbuilding still sits under permitted development: eaves, roof height, and distance to a boundary. The checks for size, floor, door, vents and anchors are set out in the [metal garden shed buying guide](/hub/garden-supplies/garden-shed-metal/sub/garden-shed-metal-buying-guide).

Question 1 of 2
What are you storing?
The YODOLLA listing is a dark grey metal cabinet at about £139.99 that UK reviewers have used for tools, cycling kit and bikes, rather than a walk-in shed with one settled footprint. It has 4.2 from 11 amazon.co.uk reviews; six UK texts were read, and German-language reviews on the same page were not used. One builder found it sturdy enough to hold their bikes and preferred it to a previous soft cover, but another says it is not enough for high-value cycles. The title says 2.8 × 1.8 ft, the dimension line says 101 × 70 × 95 cm, a door-height line says 178 cm, and the weight is 27.2 kg on one line and 36 kg in a bullet. A reviewer found tent pegs, which did not hold on concrete, and had the cabinet fixed with masonry bolts instead. The lock is described as flimsy and easy to unscrew, and the hasp takes only a lightweight padlock. One pair took three days, the plastic film took longer to peel than the build, a reviewer expects to seal gaps, and one frame arrived misshaped so the holes would not line up.
Pros
Cons
Best for: You want a low cabinet for tools or a bike, and you will measure the live page and bolt it to concrete.
Less suitable: You need a walk-in shed, or a size you can take from the title.
Specifications
Common questions
How big is this YODOLLA cabinet?
The title says 2.8 x 1.8 ft. The dimension line says 101 x 70 x 95 cm. A door-height line says 178 cm. Those figures do not describe one size.
What holds it down?
A UK reviewer found tent pegs, which did not work on concrete, and had the cabinet fixed with masonry bolts instead.
Does the listing include a strong lock?
A UK reviewer called the lock flimsy and easy to unscrew, and said the hasp only accepts a lightweight padlock.
The COZYBRITE 6 x 4 is a black hinged-door steel shed listed at 170.5 × 110.5 × 178 cm and about £149.99, and UK reviewers use it as a tool, bin or bike store once it is bolted down. It has 4.0 from 38 amazon.co.uk reviews, and 16 UK texts were read: parts are labelled and the holes mostly line up. One person finished the two flat packs in about 4–5 hours; others report about 7 hours or almost 400 screws, and the supplied driver is the wrong head. The depth is short of 4 ft, so one reviewer could not fit an adult push bike full length, and tall users duck at the door. The bullets call it a stable floor frame, but a reviewer found struts rather than a solid floor. Anchor bolts and brackets are in the box and were useful on concrete, and one owner found it quiet in hard rain once it was fixed, though another says it still needs waterproofing and one reviewer estimated the roof edge at about 1 mm. The latch does not include a lock, the hinge and latch screws sit on the outside, the listed door size copies the whole shell, and one buyer could not finish because angled panels were missing, damaged or duplicated.
Pros
Cons
Best for: You want a small bolted-down store for tools or bins, and you will add boards and a padlock.
Less suitable: You need a full-length adult bike inside, or a solid floor in the box.
Specifications
Common questions
Does this COZYBRITE 6 x 4 include floor boards?
The listing says a stable floor frame. A UK reviewer found struts, not a solid floor, and was still working out how to keep items off the ground.
Is a padlock supplied?
No. The bullets say a lockable door with a latch, and that the lock is not included. Reviewers also found the hinge and latch screws on the outside.
Will an adult bike fit full length?
One UK reviewer said an adult push bike would not fit full length. The external depth is 110.5 cm, which is short of 4 ft.
The COZYBRITE 8 × 6 is a grey sliding-door steel shed at about £239.99, listed at 231 × 171 × 181.5 cm, and one UK reviewer houses a disability scooter in it. It has 3.6 from 25 amazon.co.uk reviews, and nine UK texts were read. Reviewers are pleased once it is up and call it roomy, and one called it value for money before the roof was even on. The build is far longer than the listing's two people and three hours line: seven hours with five people, or two days, and sharp edges cut skin. The bullets describe a floor frame, and a reviewer says you buy the timber yourself. The water-resistance line says waterproof, yet one reviewer had a wet floor where the sliding doors meet and fitted a long-shackle lock because of a gap between the handles. The listed door width is 258 cm, which is wider than the shed, and the door wheels can jam when both halves sit in the channel. It ships as three packages that may not arrive together, and buyers report missing parts or more than 30 extra parts.
Pros
Cons
Best for: You want the larger COZYBRITE shell for a scooter or bins, and you can spare two days and add timber.
Less suitable: You need a dry threshold at the sliding doors, or a build that matches the three-hour claim.
Specifications
Common questions
Does this 8 x 6 include a wooden floor?
The bullets describe a floor frame to keep items off wet ground. A UK reviewer says that is a frame only, and that you buy the timber yourself.
How long did assembly take?
The listing points at a detailed instruction. Reviewers report seven hours with five people, or two days, against a claimed two people and three hours. Sharp edges cut skin.
Do the sliding doors keep rain out?
The water-resistance line says waterproof. A UK reviewer still had a wet floor where the doors meet, and fitted a long-shackle lock because of a gap between the handles.
The Garden Universe GS8-8AN is the large shell in this set: an anthracite apex shed at about £319.99, 259 × 257 × 178 cm including the roof overhangs, 94 kg, with a sliding door listed at 94 × 154 cm. It has 3.0 from 3 amazon.co.uk reviews, and all three UK texts were read. One buyer still calls it a good metal shed, and little else is praised across those short reviews. That buyer expected flooring and says it never arrived, although the title advertises a free base frame. The other texts call the instructions a guessing game, say the parts do not line up, and one box had no user guide. A padlock is not supplied, only holes in the handles, plus a ramp and two vents above the door. The water-resistance line says waterproof, which is a listing claim, and none of the three reviews describes the roof in rain.
Pros
Cons
Best for: You need the largest footprint in this set, and you will supply your own floor.
Less suitable: You are paying about £319.99 because the title says the floor is included.
Specifications
Common questions
Did buyers receive a floor?
The title says a free base frame. One of the three UK reviewers says flooring was promised and never arrived.
How large is the door?
The listing says 94 cm wide and 154 cm high. Overall size, including roof overhangs, is 259 x 257 x 178 cm. Weight is 94 kg.
What is the amazon.co.uk score?
3.0 out of 5 from 3 reviews. The texts complain about the missing floor, the instructions and parts that do not line up.
The Garden Universe GSP6-4AN is an anthracite pent shed at about £169.99, listed at about 195 × 118 × 183 cm and 49 kg, and it ships in two cartons. It has 2.8 from 6 amazon.co.uk reviews, and three UK texts were read. Those builders call it stable once it is up and big enough for their needs, and one called it value for money, but the material felt weaker than the photos and it looks less good assembled than on the listing. The build took two people a whole day, or two days, the instructions were guesswork, and the edges are sharp enough that reviewers say you need gloves. The door is 60 cm wide and 158 cm high, with two sliding doors, a ramp across the threshold, and two vents above the door. A padlock is not supplied, only holes in the plastic handles. The title includes a free base frame; floor boards are not stated.
Pros
Cons
Best for: You have measured a 60 cm opening, and you can spend a day building with gloves.
Less suitable: You need a wide door for a mower, or floor boards in the box.
Specifications
Common questions
Does the Garden Universe 6 x 4 come with a floor?
The title says a free base frame. The bullets do not list floor boards. The frame and subframe are galvanised steel, which is a listing claim, not a measured coating.
How wide is the door?
The listing says 60 cm wide and 158 cm high, with two sliding doors and a ramp. A padlock is not supplied.
What do the UK reviews say about the build?
Three UK reviews describe one or two days, awkward instructions, sharp edges, and a shell that was stable once it was up. The score is 2.8 from 6 reviews.
The Switdo NTM-37116 is listed at about £144.96 as a grey metal shed, and the listing has no customer reviews, so there is no UK account of what arrived or how long a build took. The title says 12 × 10 ft and a floor-area line says 111.39 square feet, while the dimension line says 152.2 × 83.6 × 182 cm and the weight is 26.4 kg. Those figures do not describe one shed, and the centimetre size cannot hold the lawn mower, bicycles, toolboxes and patio furniture named in the bullets if that smaller line is the true size. The kit claims a floor frame, one lock, gloves, nails, screws, four vents, a sloping roof and translucent windows. Boards are not named. The water-resistance line says water resistant, with no rain test attached, and a one-month warranty line is the only warranty wording on the page.
Pros
Cons
Best for: You would only shortlist it after the live amazon.co.uk page shows reviews and one size that matches the title.
Less suitable: You are buying on the 12 × 10 ft title as if that size had arrived.
Specifications
Common questions
Is the foot title the same building as the centimetre line?
No. The title says 12 x 10 ft and a floor-area line says 111.39 square feet. The dimension line says 152.2 x 83.6 x 182 cm. The listing has no reviews to show which figure arrived. Do not treat the foot title as the size you will get.
What floor is listed?
The bullets say a floor frame that raises the shed off the ground, plus one lock, gloves, nails and screws. Boards are not named.
How is it rated on amazon.co.uk?
The listing has no customer-review line, so the rating and the review count are not available. A score built only from the size clash is not a star rating.
Six metal garden sheds and cabinets on amazon.co.uk were scored from 0 to 100. Stars are worth up to 40, the review sample up to 25, fit as a metal shed up to 25, and value in this set up to 10. There is no lab test of the steel, the coating or the roof. The top pick is the highest score. The best value is the highest value-part score that is not that top pick. Prices and stars are the amazon.co.uk figures from 19 October 2026.
Amazon stars
40%The star part is the amazon.co.uk rating divided by 5, then multiplied by 40, and rounded to the nearest integer. A listing with no star line scores 0 on this part.
Review sample
25%200 or more reviews score 20. From 50 to 199 score 12. From 10 to 49 score 6. From 1 to 9 score 2. No reviews score 0. The part is capped at 25.
Fit as a metal shed
25%Points reflect a centimetre size you can plan from, a door and floor that are honestly described, and anchors that match the base. A title that fights the other size lines, a missing floor, or no reviews pulls this part down. It is not a coating test.
Value in this set
10%Value points sit inside this set only. A shed reviewers finish, with a larger review count at a lower price, scores higher. A thin sample, a dearer shell, or a title that fights the centimetre line scores less.
Judge a metal garden shed on the centimetre size, the door, the floor, the vents and the anchors. A foot title that fights the dimension line is not a size you can plan from. Prices and stars below are amazon.co.uk figures from 19 October 2026. Nothing here is a lab test.
A metal garden shed is a flat-pack steel building. Coated or galvanised sheet sits on a steel frame, the roof is pent or apex, and the doors are hinged or sliding. In the UK you use one for tools, a mower, bins, a bike or a scooter. Expect thin sheet and a two-person build. Which? calls metal low-maintenance once it is built, usually floorless, and dependent on ventilation. That is a note about the material. It is not a test of any listing here, and this comparison did not lab-test a shed.
A nominal 6 × 4 is not a plan until the centimetre line agrees. A door field that repeats the external size is not an opening. A door width listed wider than the shed is the same fault.
A floor frame is struts or a base. Reviewers of more than one shell found no boards, and one larger listing was reviewed by someone who says a promised floor never arrived.
Tent pegs do not hold on a pad. A reviewer who was given pegs switched to masonry bolts. Anchor bolts in the box are the kit that matches concrete.
Condensation on cold steel looks like a leak. Which? says a metal shed needs a ventilator. Blocking the vents makes a damp base worse. Dew on the roof is not the same fault as rain at the door.
External size and door size, in centimetres, come first. A nominal 6 × 4 in feet is not a plan until the centimetre line agrees with it. One walk-in is 170.5 × 110.5 × 178 cm, so the depth is short of 4 ft, and a UK reviewer could not fit an adult push bike full length. Its door line copies the whole shed, which is not a credible opening. Another pent is 195 × 118 × 183 cm with a sliding door listed at 60 × 158 cm.
A floor frame is struts or a base, not boards. A reviewer of a 6 × 4 found struts. A reviewer of an 8 × 6 bought the timber. A reviewer of an 8 × 8 says a promised floor never arrived. Another pent advertises a base frame, not a deck. Budget for boards if the bullet does not name them. Do not build in wind. Wear gloves: reviewers report sharp edges, and a two-person day is more realistic than a short time claim. Tent pegs failed on concrete for one cabinet; that reviewer used masonry bolts.
Three typical situations, each with a recommendation from this comparison.
You need tools or bins under the boundary height cap, and you will add boards and a padlock. The COZYBRITE 6 x 4 is listed at 170.5 × 110.5 × 178 cm and about £149.99, with 4.0 from 38 reviews. The depth is short of 4 ft, and the floor is struts.
You have measured a bigger footprint and you can spare a long build and buy the timber. The COZYBRITE 8 x 6 is listed at 231 × 171 × 181.5 cm and about £239.99, with 3.6 from 25 reviews. One reviewer stores a disability scooter in it. The door threshold can stay wet.
You want a low cabinet for tools or a bike, and you will not trust the foot title. The YODOLLA is about £139.99, with 4.2 from 11 reviews. The title, the centimetre line, the door height and the two weights do not agree. Tent pegs failed on concrete.
The top pick is the COZYBRITE 6 x 4 metal shed. It scores 62, the highest in this set, from 4.0 and 38 amazon.co.uk reviews, at about £149.99. Reviewers use it for tools, bins or a bike once it is bolted down. The depth is short of 4 ft, the floor is struts, and the door line copies the shell. The best value is the COZYBRITE 8 x 6 metal shed. Its value part is 5, the highest among the rest, at about £239.99, with 3.6 from 25 reviews, and a reviewer stores a disability scooter in it. The sliding-door threshold can stay wet, and the listed door width is wider than the shed. Neither score is a steel test or a rain trial.
