I would just add that over here in the US we normally say "The programmes will be broadcast starting or beginning 7 November." Of course we'd spell it 'programs' and write November the 7th or the 7th of November. Depending on context you would also commonly see 'commencing' used. But no one is going to flip their lid if you write it in the British English style.

If you are considering the start of a period as a single event, on one day, you should say "commence on". e.g. The season of performances will commence on 7 November. Here's an alternative: The programmes will be broadcast from 7 November. [We are not referring to a period here.] I am sure that I have seen native-speakers use e.g. "commence from 7 Nov". If so, it would be a small mistake.
