Transitional arrangements
Where work on site began before 6 April 2006 a building will only have to comply with the requirements of Part L 2002. Similarly, a building need only comply with Part L 2002 provided the local authority has granted full plans approval before 6 April 2006 and work begins on site before 1 April 2007. In most other cases the building must meet the requirements of Part L 2006 – see ODPM Circular 03/2006.
