Affordable Housing and Viability SPG - London Update

August 2017

On the 16th August, the Mayor of London Sadiq Khan issued the Affordable Housing and Viability Supplementary Planning Guidance (SPG).

This framework document seeks to accelerate planning decisions where residential developments of 10 or more units meet or exceed the threshold of 35% (50% on publicly owned land), thereby enabling more rapid delivery of new and affordable housing.

Where schemes meet the Mayor's threshold, they will be able to follow the "fast track route", meaning applicants are not required to submit any viability information. Schemes which do not meet this threshold will be required to follow a "Viability Tested Route", whereby applicants will be required to submit detailed viability information which will be scrutinised and treated transparently.
