I have a budlia plant [large bush ] growing through my patio slabs, it is 12 inches from the actual conservitory. Will the roots grow under and cause damage, or can I cut it right back or should I dig it all out.

Cutting it down wont stop it growing, buddlea can be cut down to the ground and regrow. You either need to treat the stump with SBK or lift some of the patio slabs and dig the root out.
