Yes, usually. A company in administration normally keeps trading. Keeping the business running is often the whole point: a trading business is worth far more to rescue or sell than a closed one. The administrator, a licensed insolvency practitioner, takes control and decides whether to continue trading in full, in part, or wind down.
So the doors stay open, the website still takes orders, and staff still turn up. But who's in charge has changed, and that affects how safe it is to deal with the company.
The first objective the law sets an administrator is to rescue the company as a going concern. Even where full rescue isn't possible, a business that's still trading, with live contracts, paying customers and a working team, sells for far more than its bare assets would fetch in a closure. So administrators very often trade the business on while they market it for sale or work up a rescue.
That's why you'll see well-known names continue serving customers for weeks or months “in administration”. The trading is deliberate, and it's protected by the moratorium that stops creditors disrupting the company while the administrator works.
The administrator does. The directors stay in office but can't manage the business without the administrator's consent, and the administrator runs it in the interests of creditors as a whole. Day-to-day, the same managers and staff may be operating things, but the big decisions (what to keep selling, which contracts to honour, whether to accept your order) sit with the administrator.
For more on what the process is and why it happens, see what “in administration” means.
Trading continues, but the safety of your position changes:
Not every administration trades on to a rescue. If no buyer emerges and the business is loss-making, the administrator may switch to a controlled wind-down: selling stock and assets, fulfilling what's practical, and closing the operation. The company then typically moves into liquidation or is dissolved. The clearest signal of which way things are going is the administrator's proposals, filed within eight weeks of appointment, covered in how long administration takes.
