Can anyone confirm if the QR LHR check-in desks still stay open continuously from the morning flights through to the last flight of the day?

There are a couple of flights close together at 08.05 and 08.35 in the morning, then an almost 6-hour gap through to the next flight at 14.15. I'm just wondering if I turn up at 9am will I be able to check my luggage or do they now close all check-in desks for a couple of hours after the first flights close?
