I've spoken with Qatar.

We've rebooked on to the next flight to SIN from DOH which means a 7 hour layover in HIA - it could have been worse!
For the future, it's worth considering departing from an airport within 500 miles of LHR (AMS and CDG spring to mind) to give you the possibility of changing to LHR in the event of a significant schedule change.
