The document is a joint response from nine London boroughs objecting to proposed changes in the London Plan Revised Early Minor Alterations regarding affordable housing rents. Specifically, the boroughs object to language that would restrict them from setting rent targets and eligibility criteria for affordable rented housing. The boroughs argue this is inconsistent with national planning policy and would prevent them from meeting local housing needs as required. They believe boroughs should have flexibility to determine appropriate rent levels and eligibility based on local evidence and market conditions.
