In October 2025, Government and the Mayor of London announced a
package of measures to support housebuilding in London.
On 28 November 2025 the Mayor of London published draft London
Plan Guidance (LPG) for consultation. The draft LPG proposes
time-limited changes to housing design guidance and cycle parking
requirements, together with a new time-limited planning route for
the delivery of affordable housing. Government is separately
consulting on a time-limited approach to Community Infrastructure
Levy (CIL) relief and introducing additional planning powers for
the Mayor.
The window for responding to either consultation closes at
11.59pm on Thursday 22 January 2026.This note summarises the
Mayor's proposed measures as to the threshold approach for
affordable housing. We do not cover the proposed tweaks to cycle
parking and housing design standards.
