When you get your seed potatoes, set them in egg boxes with the eyes facing up. Put in a light frost free area, a north facing window sill perhaps. After 6 weeks they will have sprouted (chitted).
You can get some soft plastic containers called potato planters, v. cheap from pound shops and Wilkinsons. They can be emptied and folded away for the winter. They are about 450cm high and 400cm wide, with drainage holes in the bottom. Put about 15 cm of copmost in, rest the seed potatoes (about 3) on the compost and cover with 10 cm of compost. When the leaves start growing through, add a bit more compost to cover. Keep doing this until the leaves form a big canopy above the container.
Keep the label from the seed potatoes as that will tell you when to harvest that variety. I tend to wait until the foliage starts to die back. You can gently rootle around to check if the crop is of a good size at this point.
And remember to water throughout. Also don't put these containers outside if there is still a lot of frost. It all sounds complicated, but is in fact very easy.
