The Government has told ITV News it is "concerned" about the "emerging practice" of what it calls "double charging" by estate agents.
This is where the buyer is asked to pay a fee - which can be many thousands of pounds. A Department for Business, Innovation and Skills spokesperson said:
The Consumer Minister is aware of the emerging practice of double charging by estate agents and is concerned about its potential impact on the market.
