I have bought a packet of black pepper seeds today and would like to know how to grow them in the UK. The seeds are Italian and recommend sowing in March, April, May and June, and harvesting from June onwards. If they are perennials, does the planting time have a bearing on the fruiting time? Do I need to keep them in a greenhouse, and if so, at what temperature?
They are perennials. And planting in those months gives you the best chance for germination. It is unlikely you will be able to harvest any the first season though. They will need to be in a greenhouse as they cannot take any cold what-so-ever. This article will be helpful: https://www.gardeningknowhow.com/edible/herbs/peppercorn/how-to-grow-peppercorns.htm
I am ordering a peppercorn plant or vine. I would like to know what size pot I should use or what should I plant it in?
Peppercorn Vines require an adequate size pot for root development. I recommend a glazed or raw terra cotta pot 18-24" (or more) inches in diameter and 20" (or more) in height, with adequate drain holes. Keep in mind the vine will require a trellis for support.

I have a plant that looks similar to peppercorn plant. But I am not sure if they are peppers or not. They had sprouted in my garden on their own. How to check if they are black pepper corn plant or not.
I agree that this looks like the leaf structure and pattern of the Peppercorn plant.
Until it forms the pepper seeds you will not be sure.
What am I looking for as the seeds sprout? I'm trying to grow them but have no pics of them as sproutlings. Fairly new to gardening so any help would be appreciated.
Pink peppercorns come from the Schinus molle plant. This site includes an image of a seedling:

DOES THIS PLANT HAVE FLOWERS TO MAKE THE PEPPERCORNS? WHEN SHOULD IT BLOOM?? IT HAS SMALL 'SPIKES' AT EACH JOINT OF THE VINE, WHAT DO THEY DO?
These will flower in very long clusters. The spikes at each joint can be new shoot growth, or new bloom growth. If you can send a picture then it will help me to identify what is going on. This article will give you more information on growing these: https://www.gardeningknowhow.com/edible/herbs/peppercorn/how-to-grow-peppercorns.htm
will the peppercorns sold in stores as spice sprout?
Typically, these are dried and treated in such a way that would prevent them from sprouting. There is a small chance that some of them may, but this is highly unlikely.
