Overview
The Affordable Housing Monitor (AHM) is an annual report examining the delivery of affordable housing in London and tracking the Mayor’s progress against his commitments.
This report has been produced with and for the London Assembly Housing Committee to support its annual scrutiny. It focuses on the Mayor’s delivery under the Affordable Homes Programmes (AHPs), up to March 2026.
Affordable homes in London are also funded in other ways, separate to AHP funding. The Monitor primarily focuses on homes delivered through AHP funding in London, because of the Mayor’s responsibilities under the AHP.
The Research Unit background paper on Affordable homes programmes in London provides further detail on the key elements of the Mayor’s AHPs and additional context on affordable housing in London.
