Following publication of the Enterprise Act 2002 (Merger Fees) (Amendment) Order 2009, the Department for Business, Innovation and Skills announced on 7 September 2009 that merger fees are set to double.

The new fees payable by notifying parties to the OFT apply from 1 October 2009 to all mergers where the parties cease to be distinct entities after this date. For mergers where the UK turnover of the business being acquired is £20 million or less, the fee will increase from £15,000 to £30,000; between £20 million but not more than £70 million, from £30,000 to £60,000; in excess of £70 million, the fee will increase from £45,000 to £90,000.
