I have raised Manuka plants from seeds purchased in New Zealand. They growing on in pots filled with ericacious compost and are now the size of small shrubs. Will they over-winter outside or do I need to move them into a greenhouse?

Leptospermum scoparium (AKA Manuka) can be successfully grown outdoors in the milder areas of Britain. It's hardy to about minus 10°c, so, but as yours are still young plants, and are in pots, I would err on the side of caution and keep them more or less frost-free for the time being.
