Greater London is divided into 5 sub regions for the purposes of the London Plan. The boundaries of these areas were amended in 2008 and 2011 and their role in the implementation of the London Plan has varied with each iteration.
From 2004 to 2008, the sub regions were initially the same as the Learning and Skills Council areas set up in 1999. These 2004–2008 sub regions each had a Sub-Regional Development Framework. The sub regions were revised in February 2008 as part of the Further Alterations to the London Plan. The 2008–2011 sub regions, each had its own Sub Regional Implementation Framework. In 2011, the sub regions were revised again. The 2011 sub regions are to be used for statutory monitoring, engagement and resource allocation.
