Can someone tell me what is this please, and when/how to prune?

I wouldn't prune it at all except to remove the spent flower heads next spring and then wait and see if the feeding and watering have encouraged it to bush out more form dormant buds lower down the stems. If it doesn't you could then prune back one or two stems to just above a bud to see if that works and repeat with the other stems the following year. That way you won't lose a season of those gorgeous flowers.
I have been coveting that particular form of hydrangea for a while but have found none near here since we arrived nearly 4 years ago. It's gorgeous.
