The best compost bins, compared.
Top pick: Joseph Joseph Stack 4, stone Best value: DIVCHI 300L garden compost bin – About £30.29 for 300 litres, with 4.3 from 89 reviews, the largest outdoor sample here. Updated October 2026.
Compost bin on amazon.co.uk covers outdoor heaps and kitchen caddies, and this comparison keeps both. Outdoor rows are a 160 litre dual-chamber tumbler, two 300 litre clip-together bins, an 800 litre modular double box, and a 127 litre fabric bag. A caddy stores peelings until you empty it. Site a garden bin where you can reach it, keep cooked food out of a standard heap, and do not treat a council food-waste collection as the same destination. Capacity, lids and the kitchen-or-garden split are in the [compost bin buying guide](/hub/raised-beds-greenhouses-and-compost/compost-bin/sub/compost-bin-buying-guide). One is an outdoor heap that makes a soil improver. A 300 litre garden bin does not sit on a worktop, and a 4 litre caddy does not replace a compost heap.

Question 1 of 2
Where will it sit?
The Joseph Joseph Stack in stone is a 4 litre ventilated caddy, model 30015, at about £28.07, about 16.1 × 23.5 × 19.7 cm and 800 g. amazon.co.uk shows 4.6 from 12,897 reviews, shared with the graphite colour, so this is one evidence line counted twice if you add the ASINs. Reviewers report little smell when the filter is in, a liner hole that holds compost bags, and enough room for several days of peelings. The listing points to replacing the odour filter about every three months. Complaints include the price, condensation under the liner, and a top rim that can come off if you use the caddy like a scoop tray. It is hand wash only. It is a strong kitchen holder, and the top pick in this comparison sits on the graphite twin because that pick is given once.
Pros
Cons
Best for: You want the stone colour of the Stack 4 and you will replace the filter and hand-wash it.
Less suitable: You need a cheaper caddy, or a body you can put in a dishwasher.
Specifications
Common questions
Why is the stone colour not the top pick?
The stone and graphite pages share 4.6 from 12,897 reviews. The top pick is given once, on the graphite listing. This page is the colour pair.
How do you empty it?
Through the flip lid. The listing points to replacing the odour filter about every three months. It is hand wash only.
What do reviews repeat?
Little smell when the filter is in, a liner hole for compost bags, condensation under the liner, and a rim that can come off if you mishandle it.
The Joseph Joseph Stack in graphite, model 30016, is a 4 litre ventilated worktop caddy at about £29.99, about 19.7 × 23.5 × 16.1 cm and 780 g, in polypropylene and stainless steel. amazon.co.uk shows 4.6 from 12,897 reviews, the same pool as the stone colour, and it is rank 1 in Indoor Compost Bins in this capture. It is the top pick here because that kitchen evidence is the deepest in the set, not because a lab timed the compost. Reviewers repeat the filter, the ventilated lid, and a fit with Tesco compost bags. The listing says hand wash only, and the shared notes still mention a rim that can come off and condensation under a liner. A filter is a running cost, about every three months on the brand guidance in the notes. It stores peelings. It does not replace a garden bin or the council food-waste bin.
Pros
Cons
Best for: You want a 4 litre worktop caddy with a replaceable filter and the largest kitchen review file here.
Less suitable: You need an outdoor composter, a dishwasher-safe bin, or a lower shelf price.
Specifications
Common questions
What job is this caddy for?
A kitchen worktop. It is a 4 litre ventilated caddy. It stores peelings and does not replace a garden bin.
How do you empty it?
Through the flip lid. It is ready to use. The listing says hand wash only, and the odour filter is a running cost of about every three months.
Are the 12,897 reviews unique to graphite?
No. The stone listing shows the same 4.6 from 12,897. Count that pool once. The top pick sits on this graphite page.
The cream Living Nostalgia is the same 3 litre KitchenCraft worktop caddy at about £12.89, about 16.5 × 12 × 21.5 cm and 400 g. amazon.co.uk shows 4.5 from 9,459 reviews, the same line as the French grey listing, so the cream page is a colour and price variant rather than a new test. Reviewers who discuss the caddy repeat the grey strengths: counter size and a solid feel. The cream listing also carries bullet text about a cake tin, which is not a compost specification, so ignore that block. Fly and vent complaints travel with the shared pool. At about £12.89 it is the cheaper of the two colours in this capture. Buy it for the caddy, not for the mismatched bullets.
Pros
Cons
Best for: You want the cream colour at the lower price and you will ignore the cake-tin bullets.
Less suitable: You need a listing whose bullets match a compost caddy, or an independent review sample.
Specifications
Common questions
Is this a different caddy from the grey?
It is the cream colour of the same 3 litre Living Nostalgia, at about £12.89. The 4.5 from 9,459 reviews is the shared pool, not a second test.
What should I ignore on the listing?
A bullet block about a cake tin. That is not a compost specification. Buy the caddy, not those bullets.
How do you empty it?
Lift the removable lid. It is ready to use. Fruit-fly notes on the lid vents travel with the shared review pool.
The KitchenCraft Living Nostalgia in French grey is a 3 litre carbon-steel worktop caddy at about £23.99, about 16.5 × 12 × 24 cm and 630 g. amazon.co.uk shows 4.5 from 9,459 reviews, and that count is the same pool as the cream Living Nostalgia, so you should not add the two listings together. Reviewers praise the worktop size, a strong carry handle, a charcoal filter in the lid, and a seal that holds smell when the vents are managed. Fruit flies through the lid holes are the repeated complaint, and some people tape the vents. Active cooks empty it daily, and the rubber seal needs scrubbing. It holds peelings. It does not compost them.
Pros
Cons
Best for: You want the grey Living Nostalgia on the worktop and you will deal with vent holes if flies appear.
Less suitable: You are paying for a separate 9,459-review test, or you need a bin that will not attract flies through open vents.
Specifications
Common questions
What job is this caddy for?
A 3 litre worktop holder in carbon steel. It holds peelings. It does not compost them.
How do you empty it?
Lift the removable lid. It is ready to use. Active cooks in the notes empty it daily and scrub the rubber seal.
What do reviews repeat about flies?
Fruit flies use the lid vent holes unless you tape them. The seal holds smell when you manage those vents. The 9,459 reviews are shared with the cream colour.
The EKO Puro Plus is a 10 litre black in-cabinet caddy, model EK6028-10L-BL, at about £24.99, about 27.4 × 21.2 × 31.7 cm and 840 g. amazon.co.uk shows 4.5 from 542 reviews. Reviewers use it as a daily workhorse, like the stay-open lid for scraping plates, and say the bag retention works once you learn the tuck. It hangs on a cupboard door or adhesive mount, so it saves worktop space compared with a 3 or 4 litre caddy. The same notes say the bag tuck takes practice, the bin feels smaller if you remove the inner part, and the lid could be heavier. The box names plastic, without a polymer grade. It holds more scraps between trips, and it still empties to a heap or a council bin rather than composting on its own.
Pros
Cons
Best for: You have no spare worktop and want a 10 litre caddy on a cupboard door.
Less suitable: You want a filter caddy in plain sight, or a bin you can use without learning a bag tuck.
Specifications
Common questions
Where does it sit?
On a cupboard door or an adhesive mount. It is the 10 litre option when the worktop is already full.
How do you empty it?
Lift it off the hook. Reviewers say the bag tuck works after practice, and the bin feels smaller if you remove the inner part.
How big is it?
10 litres, about 27.4 × 21.2 × 31.7 cm and 840 g, at about £24.99, with 4.5 from 542 reviews.
The KitchenCraft KCCOMPBIN is a cream metal pedal caddy of 3 litres, about 9 × 12 × 16 cm and 800 g, at about £18.70. amazon.co.uk shows 4.4 from 338 reviews, a real sample that is not shared with the Living Nostalgia colour pair. Reviewers like the pedal lid, the vintage look, the carbon filter, and an inner bucket that lifts out. The same notes say it tips when you pedal it on the floor, that it is smaller than an old plastic bucket, and that the pedal is awkward under a counter. It is a kitchen holder, not a garden composter. A 3 litre bucket fills quickly if you cook every day, and the filter does not make cooked food safe for a standard heap.
Pros
Cons
Best for: You want a cream pedal caddy on a worktop, with a filter, and you will not stand it on the floor.
Less suitable: You need floor stability, or an outdoor bin that makes compost.
Specifications
Common questions
What job is this caddy for?
A 3 litre metal pedal caddy for the kitchen. It is not a garden composter, and the filter does not make cooked food safe for a standard heap.
Where should it stand?
On a worktop. Reviews say it tips when you pedal it on the floor, and the pedal is awkward under a counter.
Is the review count shared?
No. 4.4 from 338 reviews is its own line. Do not mix it with the Living Nostalgia pool of 9,459.
The SQUEEZE master listing is a 160 litre dual-chamber tumbling composter in polypropylene, at about £58.63, with a stated weight of 10.6 kg and a drum footprint of 57 × 57 × 23 cm. amazon.co.uk shows 4.4 from 194 reviews. Reviewers who finished the bolted build often call the panels sturdy, the doors a useful size for loading, and the drum easier to turn than an old dustbin tumbler. One buyer says the seller replaced missing screws quickly, which is the delivery complaint that repeats. Assembly is fiddly, and the stand needs a level hard surface or the drum will not sit square. The two chambers let you fill one side while the other rests, though these notes have no measured composting time. At this price you are paying for turning, not for the cheapest 300 litres.
Pros
Cons
Best for: You want a compact outdoor tumbler on a hard standing and will spend time bolting the panels.
Less suitable: You need the cheapest litres, or you have only uneven soil and no level base.
Specifications
Common questions
What job is this listing for?
An outdoor garden. It is a 160 litre dual-chamber tumbler in polypropylene, not a kitchen caddy.
How do you empty it?
Through the drum doors. The panels are bolted, and the stand needs a level hard surface or the drum will not sit square.
Does it state a composting time?
No measured composting time is in the notes. You are paying for turning. About £58.63 is well above the 300 litre clip bins.
The PRADICHI page is a black and green clip-together garden bin at about £29.29, with dimensions of 81 × 60 × 60 cm and 4.4 from 27 amazon.co.uk reviews. Bullets describe a 300 litre bin with a snap lid and a bottom door, but the capacity field prints 1000 kilograms, so you should follow the litre claim in the bullets and ignore the kilogram line. Reviewers who assembled it without tools call the lid secure enough for pests and the body sturdy enough for the job. A few still call the plastic flimsy, and one piece can be fitted backwards if you do not check the clips. The sample is small next to the DIVCHI 300 litre bin at a similar price. It is a low-cost static heap, not a tumbler, and the listing does not name a rat test.
Pros
Cons
Best for: You want a cheap static 300 litre bin and you will treat the kilogram capacity line as a listing error.
Less suitable: You need a large review file, or a tumbler you can spin instead of forking.
Specifications
Common questions
Which capacity figure should I use?
The 300 litre bullets. The capacity field that says 1000 kilograms clashes with those bullets. Ignore the kilogram line.
How do you harvest it?
Through the top hatch and the bottom door. Assembly is tool-free clips. A panel can be clipped the wrong way round.
How large is the review sample?
4.4 from 27 reviews. That is a thin sample next to the DIVCHI 300 litre bin at a similar price.
The Krzaw listing is a dark green 127 litre PE compost bag, 45 × 45 × 80 cm, at about £10.99, with a stated weight of 200 g. amazon.co.uk shows 4.4 from only three reviews, which is too small a sample to treat as a settled score. Those notes call the bag well made, praise a strong zip, and find the viewing flap useful. They also say the handles are fabric rather than the steel the marketing claims, that harvest through the bottom is hard, and that the bag sits on the ground so worms cannot reach the soil. A zip lid is not the same as a rigid snap lid. At this price it is a trial sack, and you should not treat a six-week marketing claim as a UK winter result.
Pros
Cons
Best for: You want a cheap first sack on a small plot and you will not treat three reviews as a test.
Less suitable: You need a large UK review file, a rigid lid, or compost that stays in contact with the soil.
Specifications
Common questions
What job is this bag for?
A 127 litre outdoor PE sack at about £10.99. It is not a rigid bin, and a zip lid is not a snap pest lid.
How do you harvest it?
Through a bottom velcro window. The three reviews say that harvest is hard, and the bag blocks worm contact with the soil.
Can I trust the 4.4 score?
That score is three reviews. Treat the bag as a trial sack. Do not treat a six-week marketing claim as a UK winter result.
The simplehuman CW1645 is a 4 litre brushed stainless caddy at about £49.95, about 24.5 × 12 × 22 cm and 1.36 kg. amazon.co.uk shows 4.3 from 2,135 reviews. Reviewers praise the build, an inner bucket that is easy to clean, a footprint that fits a windowsill, and a soft-seal lid that controls odour. The price is the obvious limit: it costs more than the Joseph Joseph Stack and far more than a Living Nostalgia. The hinge is a repeated weak point if you carry the caddy without taking the lid off first. Some buyers also find 4 litres smaller than other caddies they have used. It is a premium holder for scraps, not a garden composter, and the seal does not make meat or cooked food suitable for a standard heap.
Pros
Cons
Best for: You want a stainless caddy with a soft-seal lid and you will lift the lid off before you carry it.
Less suitable: You are choosing on price, or you need more than 4 litres on the counter.
Specifications
Common questions
What job is this caddy for?
A 4 litre stainless worktop holder with a soft-seal lid and a removable inner bucket. It does not compost the scraps.
Why is the hinge a risk?
Reviews say the hinge can break if you carry the caddy without taking the lid off first. Lift the lid off, then carry it.
How does the price compare?
About £49.95 is the dearest kitchen caddy in this set, above the Joseph Joseph Stack and well above a Living Nostalgia. The 4.3 from 2,135 reviews is its own file.
The DIVCHI listing is a 300 litre black and green plastic garden bin, 81 × 60 × 60 cm, at about £30.29, with 4.3 from 89 amazon.co.uk reviews. That is the largest outdoor review file in this set, and it is the best value row when you want litres per pound rather than a kitchen caddy. Reviewers describe an easy, light build and several say they are replacing wooden bins. You still have to clip the panels carefully or they stress, and one review finds the lid clips frustrating. Another says the lid may need a weight in sun. The specification weight of 200 g is not credible for an 81 cm bin, so ignore that figure. It is a static fill-from-the-top heap with a bottom door, not a sealed system for cooked food.
Pros
Cons
Best for: You want about 300 litres of static garden compost at around £30 and a review file you can actually read.
Less suitable: You need dual chambers, a spin drum, or a bin that states a believable shipping weight.
Specifications
Common questions
What job is this bin for?
An outdoor garden heap. It is a 300 litre static clip bin with a snap lid, not a kitchen caddy and not a tumbler.
How do you empty it?
Through the top hatch and the bottom door. The panels use tool-free clips. Force them and they can stress.
Is the 200 g weight real?
No. That specification line is not credible for an 81 cm bin. Ignore it. The useful figures are 300 litres and about £30.29.
The B2C listing is an 800 litre black modular double box at about £65.98, about 135 × 72 × 83 cm, with 3.2 from 25 amazon.co.uk reviews. That is the lowest star line in this comparison. Buyers who finished the build say the size suits an allotment and that the light panels feel firmer once clipped. Others report clips that are too tight for the panel thickness, hours spent modifying them, and instructions that swap parts C and D. Some buyers could not assemble the box at all. Material is listed as plastic and PVC, and the capacity sentence on the page is marketing copy rather than a tested litre figure. Volume only helps if the clips go together. Under the Consumer Rights Act 2015, goods that will not assemble are a quality problem, not a pest problem.
Pros
Cons
Best for: You need two large bays, you have checked allotment rules, and you will inspect the clips before you rely on the box.
Less suitable: You want a bin that reviewers agree goes together the first time.
Specifications
Common questions
What job is this box for?
An 800 litre outdoor modular double box, if the clips go together. Check allotment rules before you rely on the volume.
What do reviews say about assembly?
Some finished builds like the allotment size. Others could not seat the clips, and instructions are reported to swap parts C and D.
Is 3.2 a large sample?
It is 25 reviews, the lowest star line in this set. Volume only helps if the box stands. Goods that will not assemble are a quality problem under the Consumer Rights Act 2015.
Twelve amazon.co.uk listings, captured on 20 October 2026, are on this page. There is no laboratory composting trial. Amazon evidence is 40 points, fit for the stated job is 35, and value is 25. A kitchen caddy is not scored against an outdoor bin on litres. Shared review pools on the Joseph Joseph colours and the Living Nostalgia colours are counted once. On the cards the top pick is the Joseph Joseph Stack in graphite and the best value is the DIVCHI 300 litre bin.
Amazon evidence
40%Star line plus whether the review sample is unique to that ASIN. The shared Joseph Joseph 4.6-from-12,897 block and the shared Living Nostalgia 4.5-from-9,459 block are each one sample.
Fit for the stated job
35%A worktop caddy is scored as a holder. An outdoor bin is scored as a heap: form, lid, access and whether the listing matches that job. Litres only count inside the same job.
Value
25%GBP shelf price against the job. Outdoor value is litres per pound with a review sample you can read. Indoor value is a usable caddy, not the most litres.
Match the job first. A kitchen caddy and a garden heap are not the same product, even when both are called a compost bin.
A compost bin on amazon.co.uk is sold as two different tools, and this page keeps both. One is an outdoor heap that makes a soil improver. The other is a kitchen caddy that only holds peelings until you empty it into a heap or a council food-waste bin. Match the job before you compare litres. A 300 litre garden bin does not sit on a worktop, and a 4 litre caddy does not replace a compost heap. The outdoor listings are five shapes.
A 300 litre or 800 litre outdoor bin does not belong on a worktop. If you only need to hold peelings, use a 3, 4 or 10 litre caddy and empty it to a heap or the council food-waste bin.
The two Joseph Joseph colours share 4.6 from 12,897. The two Living Nostalgia colours share 4.5 from 9,459. Each pair is one sample. A 4.4 on three Krzaw reviews is not a larger sample than 4.3 from 89.
Recycle Now and Hampshire keep cooked food, meat and fish out of a standard heap. A snap lid does not change that. England’s food-waste collection from 31 March 2026 is a council stream, not a garden composter.
Decide the job before the litres. Outdoor forms here are a 160 litre dual-chamber tumbler, two 300 litre static clip bins about 81 × 60 × 60 cm, an 800 litre modular double about 135 × 72 × 83 cm, and a 127 litre PE bag. Indoor forms are a 3 litre pedal caddy, two 3 litre Living Nostalgia worktop caddies, two 4 litre Joseph Joseph filter caddies, a 4 litre simplehuman soft-seal caddy, and a 10 litre EKO hang caddy. A caddy does not make compost.
Gardeners’ World looks for a lid and a bottom harvest on static plastics. The 300 litre pair has a snap lid, a top hatch and a bottom door. The tumbler uses drum doors on a bolted stand. The fabric bag uses a zip and a bottom velcro window, with only three reviews. Indoors, filters and seals are the odour tools: Living Nostalgia reviews report fruit flies through lid holes, and the Joseph Joseph listing points to a filter change about every three months. Count each shared colour pool once.
Three typical situations, each with a recommendation from this comparison.
You need a kitchen holder before the council food-waste bin, not a garden heap. The Joseph Joseph Stack in graphite is about £29.99, 4 litres, with a replaceable filter. The 4.6 from 12,897 reviews is shared with the stone colour.
You want about 300 litres of static garden compost and a review sample you can read. The DIVCHI clip bin is about £30.29, with 4.3 from 89 reviews, a snap lid and a bottom door. Ignore the 200 g weight line.
You want two chambers you can turn, and you have a level hard standing. The SQUEEZE master is 160 litres at about £58.63, with 4.4 from 194 reviews. Check site rules before food waste, and do not treat the 800 litre box as assembled until the clips seat.
Twelve listings are on this page, and none was composted in a lab. The Joseph Joseph Stack in graphite, about £29.99, is the top pick: a 4 litre filter caddy with 4.6 from 12,897 amazon.co.uk reviews, shared with the stone colour and counted once. The DIVCHI 300 litre bin, about £30.29, is the best value: 4.3 from 89 reviews, the largest outdoor sample here, on a static clip body. A caddy holds peelings. A 300 litre bin is a heap, not a sealed system for cooked food. Skip the 800 litre modular box if you need a build that reviewers agree goes together the first time.
DIVCHI 300L garden compost bin
About £30.29 for 300 litres, with 4.3 from 89 reviews, the largest outdoor sample here.
