Be proactive. Everyone else will be.
Review your contract terms as @AJB Temple says. This is important.
Contact the administrators as @Noel says. State what you are owed and assert your rights over your property if title is still yours.
The administrators are required to follow the hierarchy of claims over the assets of the business. They'll be scambling to get control of it, lock it down and understand the mess that they have on their hands. Staff have to be laid off with urgency, so there isn't a functioning business there any more just the administrators, some key staff kept on for now and a bunch of people possibly working out their notice but totally distracted by the need to find other jobs.
