"Eve Price" has grown to 2mx2m in my garden in West Yorkshire, on top of a moor. It flourishes, despite being in an exposed position. I use it as part of an informal mixed hedge and trim it in early spring.
I think, if you prune in early spring you can restrict its size but it may look gnarled if you trim too much (though it will recover: it's a tough old shrub). It will have to grow to produce those fragrant flowers and dark blue berries and I know, when I've been a bit keen, it hasn't flowered as happily.
Find somewhere where it can spread and do its thing!
