Depends on the airport.
Where I work for instance, the airport itself is certified for take off and landings down to 400 M visibility (we have no RVR equipment), but you can still taxi with less. But since we have no stopbars etc. , we're limited to one aircraft on the manoeuvring area at a time.
Departure with visibility above 400 M is pilots discretion, and some airlines have more strict requirements than others.... we have tried having aircraft lined up and counting lights to see if they could "see far enough", even had a vehicle driving out to mark their desired visibility range in the hope they could see that far.
Some would say nope, and the next in line be fine with the 400.
Though I'm pretty sure that is not Heathrow procedures
