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, 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.

Took ages to set up By Anonymous 2 22nd March 2015

I have had these compost bins before and all I had to do was slot them together. This time I was faced with drilling hundreds of screws and, never having used a drill before I couldn't do it. I had to employ someone to put the bins together for me which wasn't what I had in mind. Why are the metal parts not already screwed on to the wood. Its complete madness when it would take minutes in a factory setting. I will never buy compost bins from you again.

Almost perfect! By N Shelton-Smith 4 9th February 2015

I purchased the single starter bin, and although I agree with the comments regarding assembly, I did not find it too hard! However, I do have one problem. The web site shows all three bins nicely erected and positioned in the middle of the lawn!!! My bin is situated at the bottom of the garden in a secluded corner. It was only after getting it into position that I realised that the next bin was going to be a problem. I assume that when I order the next bin it will come with the additional metal angles to add to the two external corner posts. As my (nearly full) bin is against a fence, I can forsee problems in drilling and fixing the brackets. I think it would be useful if there was an option to purchase the brackets separately when ordering the starter bin. However, the first one looks good and I am sure will do the business!!

A Pleased Hubby! By Anonymous 5 28th November 2014

I purchased a double compost bin, was very pleased with it so added to it along with the lids. The triple bins are now installed and starting to do their job. Hubby was pleased with the instructions etc.

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!"
