I have 6 year old Quince Vranja. Despite it having abundant blossom, and the bees working it busily, I end up with only 2 or 3 fruits that fully form. I do not prune it. I live in Ynysybwl, near Pontypridd. What, if anything I am doing wrong

Quince trees like a lot of water, so it may be that it is getting too dry and dropping fruits.  You could try mulching the soil next winter to help with water retention.  If there is stuff growing at the base, clear it away.  Grass and other plants around the trunk can really knock a young tree back.

If the tree is growing very fast, it could be putting more energy into leaf and branch than fruit.  You could try pruning this winter to focus its energy into less branches and hopefully more fruit. 

Mine has off years when I get nothing, but the following year it is usually laden. After 6 years you should be getting more than a couple of fruits.  If the tree flowers, that is a good sign, so with any luck it should not be too tricky to get yours into production.
