For heritage varieties, good for the home grower try
http://www.thomasetty.co.uk/ (used these, good)


Try also https://seedsofitaly.com/, which generally have much larger
packets (useful for me), and http://www.realseeds.co.uk/ for more
heritage varieties (my experience with Thomas Etty has not been very
good). I also use King seeds, Unwins and more, but I do tend to
want specific, non-mainstream varieties of a couple of dozen types
of vegetable and herb.

https://edwintucker.co.uk/seeds/garden-seeds/ (heard good reports on
these)

They are no longer trading, unfortunately. The only supplier of seeds
in bulk I have found is https://www.wholesale.molesseeds.co.uk/, but
their germination is patchy - however, with enough seeds, that's not
a major problem.
