About us

M&B Williams (Brecon) Ltd are the largest worm breeders and suppliers in the U.K.

As a result we are the only dedicated U.K. company with a consistently large supply of wormcast product.

Processed and screened to the exacting requirements for both the Horticultural and Amenity markets. M&B Williams Brecon can provide environmentally sound products and solutions.

By the feeding action of earthworms, our unique products are the result of the action of millions of earthworms passing recycled organic matter through their gut a number of times. During this process of fragmenting and grinding the organic matter becomes finely divided humus like material with high porosity, aeration, drainage and water holding capacity. This process greatly enhances microbial activity and accelerates the rate of decomposition. This leads to a humification effect where unstable organic matter or decomposing plant and animal matter is oxidized and stabilized. Research scientists have termed this process vermicomposting.

We provide ecological recycling waste management solutions »

So the real stars of our show exist backstage in their millions, always working, always performing - just what you would expect from earthworms.

M&B Williams Brecon (Brecon) are probably the most ecologically obvious organic products you can ever imagine.
