Depends on size of plant and size of pot and how cold your winters get.
If too small there is risk of frost damage to the plant if planted out as well as frozen roots and compost if it stays outside in the pot. If it's a decent size and your winters aren't extreme then autumn is the best time for it to be planted outside as long as you prepare the soil well and give it a good drink to get it going.

Thanks Obelixx. The plant is in a 7.5 litre pot and about 80cm high. I'm hoping to get it fairly quickly up to about 1.6m high to replace a failing plant that forms part of a screen in the garden. It will obviously take time to fill out enough to fill the gap. We live near the South coast in Devon so our winters are mild.
I have the choice of planting it now, placing it in a sunny spot or putting in the conservatory until Spring. I do not know if best to get the roots established in the ground now or mollycoddle it with warmth in the conservatory in hoping to keep it growing throughout winter. Re-potting in a bigger is obviously an option if not planting now,
I'd put it out now, you've probably a couple of months before real frosts. Better to get some root establishment over winter, than tender top growth from being in a S facing conservatory.
The thing to remember is , if you hadn't bought it, it'd be left outside all winter at the nursery / garden centre. I think you'd do it more harm than good bringing it indoors
