From the DfE - I note that the draft code does not have the date that it comes into effect from, and guess that will not be decided until its put before the house.
"The Codes and draft regulations will be laid before Parliament in December, in order to come into force in February 2012, and thereby affect the allocation of places for children starting school in September 2013."

" Parents will have at least 20 days to lodge an appeal against primary or secondary school decisions. The current 10-day limit means parents must appeal quickly but many then drop the appeal because they later get an offer at another of their preferred schools. In the last school year for which figures are available (2008/09), more than a quarter of all appeals lodged (24,550 out of 88,270) were not taken forward, wasting time and money.
Guidance against hearing appeals on school premises will be overturned. At the moment admission authorities sometimes have to make costly, taxpayer-funded bookings of hotels or conference rooms.
Admission authorities will no longer be required to advertise for lay appeal members every three years, but must ensure that panel members are independent and that they retain their independence for the duration of their service."
