My feeling is that this is just an introductory offer and when they have enough liquidity they will start charging fees for trading.

London-based digital currency exchange Coinfloor has announced it will adopt a 'no-fee' bitcoin trading policy beginning later this week.
With the move, Coinfloor, one of the larger players in bitcoin's still nascent GBP market, embraces a pricing strategy that is comparable to the industry's largest, though primarily China-based exchanges, which have long withheld fees on bitcoin-denominated trades.
Speaking to CoinDesk, exchange representatives indicated that the move is designed to boost liquidity at the exchange, the largest GBP bitcoin trading platform by volume, according to data from Bitcoinity.
...Coinfloor said it will continue to charge for bitcoin withdrawals, as well as GBP deposits and withdrawals.

It is perfectly possible to cover their expenses with fees on "bitcoin withdrawals, as well as GBP deposits and withdrawals". 0 fees is a perfect environment for liquidity providing trading bots. However a maker-taker fee structure that is free for makers can accomplish the same thing while preventing wash trades.
