Depends if their suppliers, fuel, catering, etc think they will get paid or move to rescind their contracts.
They have less to worry about now as the administrator guarantees payment from their own pocket for any debts incurred once they take over. Note that certain entities can't have contracts with a company in administration, I remember that Australia Post was one of them but stand to be corrected by anyone with more up to date information as I'm going back 20+ years.
