Buy 3 Medium Bin Starter System (Includes Lids) GCO-040 & Save £25!

The Harrod Slot & Slide Compost Bins have been carefully designed to create an efficient and dependable garden compost bin, manufactured from thick 15mm planks which slide into strong aluminium post fixings for easy access to turn the compost pile or collect finished compost. 

The compost bins are available in 2 sizes; 564 Litre (78cm High x 93cm square) and 1219 Litre (78cm High x 1.33m square) and are supplied as single compost starter bins (excluding lids), or add additional bins to create a continuous composting system.  The 3 bay 564 Litre starter system (as seen in the main image) is supplied with lids. 

Our unique design offers a generous capacity to help create intensive core heat, as big compost heaps are self insulating. Manufactured from high pressure treated Scandinavian softwood the composters have good airflow and the optional lids keep the heat in for faster composting and will deters pests and help keep moisture levels constant.

The bins require some initial construction and we recommend using an electric screwdriver to fix the end plates to the planks which then allow the planks to easily slide up and down the aluminium post fixing plates, for easy access to the bin to turn and aerate the heap – essential for promoting oxygen and increasing microbial activity.

Compost Bin medium system By Andrew Gray 2 9th June 2015

My experience is similar to that of others. The product is not really up to the job unless you put some work in of your own. Not only the hundreds (yes, hundreds) of screws (all could be factory done without adding to packaging bulk) but I advise: 1. screwing battens to the uprights at the base of the three sides that you are not using to access in order to secure the geometry of the bins especially as the uprights do not go into the ground (my bin system blew over when empty!) 2. adding grab handles to the lids to help access and bind the quickly warping slats together better and prevent them so quickly disengaging from the short nails (the only fixings done by the manufacturer) to the under-battens. So from a design and construction point of view, these bins are pretty sloppy - not usual Harrod quality. But after a few months the first bin has made reasonable compost.

Good but could be better By Anonymous 4 1st June 2015

I agree with a lot that has been said by other reviewers but additionally the black screws of which there are plenty are covered in filings and as a result if you are not careful you can end up with them stuck in your thumb and fingers from holding while afixing. I had over 30 splinters before I realised then had to wash them to avoid many more. Also as others have said that the boards have starred to warp. I've only had it three weeks.

OK BUT NEEDS IMPROVEMENT By Peter Kinnaird 3 24th April 2015

Enough is already said here by other reviewers concerning the assembly issue. It is not difficult - simply too much hassle with all those screws to insert. The finished product is good albeit a bit flimsy - and my boards have started to warp an twist after just a week. However I could find nothing else similar to this product on the market with anything like the same capacity as the larger option.Lids seem expensive and not needed?

What can go in to a conventional bin and how does it all work?

Success depends on heat, biology and a good balance of ingredients, added in approximately 10cm. layers.  ‘Green’ waste (grass, border and hedge trimmings, snipped or shredded woody prunings) heats up steamily, starts to break down rapidly and can be stirred into layers below to speed everything up.  ‘Brown’ waste (e.g. shredded paper, packaging and straw) should be added at regular intervals to counteract the wetness of the greenery and will rot down too.  Manure from herbivores (chickens, pet rabbits) adds zest to the whole mixture, as does the odd spadeful
of soil.

Autumn leaves are best composted on their own in hessian bags or cages, since they rot down more slowly and in a different way.

What shouldn’t go in?

Moss (which refuses to rot and can therefore be unwittingly spread around)
Seeding weeds or garden thugs (i.e. Verbascums, Fennel) Roots of perennial weeds such as ground elder and bindweed – unless they are thoroughly dried off in the sun first. Cat and dog (i.e. carnivore) manure. Meat or cheese kitchen scraps or vegetable waste that has been contaminated by them.

Common problems

Too dry?  Water the heap and/or add more greenery and cover it tightly to keep the heat in.

Smelly?  Add more ‘brown’ ingredients, but no grass clippings or kitchen waste for a while.  Stir the contents to open it up.  Leave the lid off.

Rats? This is a tricky one - they may try to move in if there is a regular source of food nearby (i.e. a bird table or poultry house).

Slugs and snails?  No problem.  They are doing their bit for the composting process, and at least it keeps them away from your lettuces and hostas.


Our Horticulturist says; "Home composting is a must for any serious gardener. Well rotted compost adds essential organic matter to soil along with humus and greatly improves structure and the soil's ability to hold onto water and nutrients.

What's more, home composting is free, can be easy and greatly helps the environment as less compostable material makes it to landfill sites where it produces harmful methane gas - and you cut down on trips to the garden centre to buy compost too. It's a win/win situation!

It's also surprising how much compostable material your garden and kitchen produces; of course there's the usual, stems, deadheaded flowers, leaves and spent plants from the veg patch or border but don't forget kitchen peelings, cardboard and newspaper from inside the house. Filling a bin or building a heap is never a problem!"

Composters and Wormeries on Test - Dave Finkle

If you are up for a bit of light construction then get your hands on these handy composters, they require and hour or two to assemble. These solid compost bins look traditional and practical and concept is very well though out - the planks slide in and out with ease, permitting easy control and access when managing your black gold. I think the most impressive point is the flexibility the range offers - you can simply add on another bay as and when you need. If this isn't enough, the timber is pressure treated and provided with a three year structural warranty. A sound purchase in my view!
