Could well be Gaultheria procumbens.

Pernettya mucronata, judging by the leaves... now reclassified as Gaultheria mucronata...

I can never remember if Pernettyas are now Gaultherias or if it is the other way round! Plants are deaf so I don't suppose it matters too much what you call them.

Many thanks for this. Now we know what it is and that it is female, my friend is going to get the male partner for it so that it has the opportunity to fruit again next year.

Massive thanks,

Gareth

If your friend plans to repot it or put it in the ground best tell him that its an acid lover and will need ericaceous compost.

Your friend doesn't need a male plant Gareth the bees will fertilise the flowers and he'll get berries - unlike holly and some other trees!

Erm, a male is most likely needed if you want berries, although there are some self fertile varieties (G. mucronata 'Bell's Seedling' for instance), but if you don't know which variety you've got, then having a male plant will ensure berrying. You could wait and see next year, and if it produces berries on its own, then you'll know its self fertile...

Ours certainly is, not another Gaultheria in the garden.
