Heathrow upperclass bag drop

Hi everyone

What is the earliest we can drop our bags at the Upperclass suite at Heathrow for our 8.20pm flight to Boston as we want to maximise our time in the clubhouse.
Thanks

As early as you like on the day (well 6am or thereabouts). There is no time limit at LHR.
