How to use a compost bin UK
Updated: October 2026
You have a bin in the garden, or a caddy by the sink, and the first week already smells wrong. How to use a compost bin UK depends on which of those you own. An outdoor heap needs a site, a mix and a harvest. A kitchen caddy needs a daily empty and a plan for flies. This page is the method. Rankings and prices stay on the [compost bin comparison](/hub/raised-beds-greenhouses-and-compost/compost-bin). The Products Compared editorial team wrote it on 20 October 2026 from Recycle Now, the Royal Horticultural Society and the review themes on these amazon.co.uk listings. It is not a timed lab trial.

Set the outdoor bin before you fill it
Stand a static bin in shade, on bare soil if you can, close enough that you will use it in winter. Recycle Now treats bare soil as the better base. Hampshire County Council accepts concrete if you spread a layer of soil first. Leave space for the lid and the bottom hatch. A 300 litre prism here is about 60 cm square and about 81 cm tall.
A tumbler is the exception. The 160 litre dual-chamber drum stands on a hard, level surface. If the patio slopes, the stand rocks. Use the two chambers as two batches, not as one barrel you stir every day. The Royal Horticultural Society describes the bin’s job as keeping rain off, holding warmth, draining and letting air in. A mass under about 1 cubic metre warms more slowly. Gloves and a mask are worth wearing when you turn the heap, because spores and dust are the reason.
Fill it so the mix can actually work
Recycle Now’s working mix is about half greens and half browns. Greens are soft and wet: vegetable peelings, grass in thin layers, coffee grounds. Browns are dry and stiff: torn cardboard, woody prunings, scrunched paper. A bin of nothing but grass cuttings slumps into a wet mat. A bin of nothing but cardboard stays dry and stalls.
Add material in layers you can still disturb with a fork on a static bin. Keep meat, fish, dairy and cooked food out of this heap. That exclusion is the home-composting rule from Recycle Now, and it is the difference between a garden bin and the council food-waste bin. The detail on rats is on compost bin rats. Loose tea and coffee grounds are normal greens. If the tea bag is plastic, empty the leaves and bin the bag. A few citrus peels are fine in a mixed heap. A bin that is only orange peel is a balance problem.
Tumbler care, static care and harvest
On a static bin, turn or aerate when the heap is slimy or smells of rotten eggs, and add browns if it is wet. If it is dry and pale, add greens or a little water. Gardeners’ World troubleshooting follows that same wet-or-dry split. You do not need a daily turn. Recycle Now’s typical wait for a static bin that you keep topping up is nine to twelve months. That is a public rule of thumb, not a stopwatch result for the DIVCHI or PRADICHI listing.
Harvest from the bottom door when the material at the base is dark, crumbly and smells like soil. The fresh waste stays on top. If the door only releases wet lumps, it is not ready. On the fabric bag, reviewers already find the bottom opening awkward, and the bag does not give worms a route into the soil. On the tumbler, rotate the chamber you are filling and leave the resting chamber alone. There is a thermometer in the marketing for this 160 litre drum. This comparison does not treat that as a measured compost temperature.
The kitchen caddy is a daily loop
Empty a worktop caddy before it weeps. A 3 litre Living Nostalgia fills in a day or two if you cook a lot. A 4 litre Joseph Joseph can hold several days of peelings if the filter is in place. Replace that odour filter about every three months. A 10 litre EKO on the cupboard door lasts longer between walks, once you have learned the bag tuck.
The Joseph Joseph notes mention Tesco compost bags. Condensation still collects under a liner, so rinse the bucket. Take the simplehuman lid off before you carry that caddy, because the hinge fails. Hand wash is the Joseph Joseph instruction. Fruit flies on the Living Nostalgia reviews come through the lid vents. Where the caddy then goes is the split on kitchen compost bin or garden compost bin.
Common questions
Where should the outdoor bin stand?
Put a static bin in shade, on soil or on concrete with a soil layer, where you can open the lid and the bottom hatch. Put a tumbler on level hard standing. A forgotten corner behind a wet shed is the usual reason a bin stalls, even when the plastic is fine.
What mix of greens and browns should I use?
Aim for about half and half, which is the Recycle Now proportion. Greens are peelings, grass in thin layers and coffee grounds. Browns are torn card, paper and woody stems. If the heap slumps and stinks, add browns. If it sits dry and cold, add greens.
How long until compost is ready in a dalek?
Recycle Now gives nine to twelve months as typical for a home heap you keep filling. It is not a guarantee for a particular 300 litre listing, and it is slower if the bin stays under about 1 cubic metre or sits in deep shade with no turning. Harvest only the dark, crumbly layer at the bottom.
How often do I turn a tumbler?
Turn the chamber you are filling often enough to keep air in it, especially after a wet load of peelings. Leave the resting chamber still. This file has no tested timetable in days for the 160 litre drum, so use the look and the smell, not a marketed week count.
How do I empty a kitchen caddy without smells?
Empty it while the scraps are still fresh, keep the lid shut, and rinse the bucket. Use the filter if the caddy has one, and replace a Joseph Joseph filter about every three months. If flies are already in the lid vents, tape those holes and empty daily until the cycle breaks.
Can I put tea bags in?
Loose tea and coffee grounds are fine as greens. A plastic tea bag will not rot, so tip out the leaves and throw the bag away. A metal staple is a smaller nuisance you can pick out later. This is a materials check, not a claim that every brand of bag is compostable.
