You can also look for cover crops at the market, especially the natural foods store. Many beans that are sold dry by the pound, for example, are viable seed and will both make organic matter and fix nitrogen for you. Some other soil improvers are sold for special purposes, like daikon radish seed, which is sold for sprouting but could also be planted -- and it's available through Amazon.co.uk.

Thanks. I got some seeds of Amazon in the end. Hate to give them money but couldn't find another source.
