No access either on the day of arrival (unless you arrive before 14:00 hrs and can use the Concorde Breakfast Room) or the next day. Same day connections would be fine for CCR access.
More details in the lounge access guidelines in the Dashboard.
Edit: welcome to Flyertalk ljheyman, welcome on board to the BA forum in particular, I hope despite missing out on the CCR that you have a good flight to Paris, and that you continue to participate here.
