Greater Cambridge’s new Local Plan has entered its final public consultation, giving residents, businesses and organisations until 25 September to comment before the document is submitted for independent examination.
The consultation opened on 3 August and concerns the Proposed Submission version of the first joint Local Plan for Cambridge and South Cambridgeshire. It will shape planning decisions across the area over the next two decades, including where new homes and workplaces are built and how transport, water, biodiversity and other infrastructure are expected to support that growth.
A final test before examination
This stage is more tightly defined than earlier rounds of consultation. According to Greater Cambridge Shared Planning, representations are now focused on whether the plan is legally compliant and “sound” under national planning policy. The tests include whether the plan is positively prepared, justified, effective and consistent with national policy.
That distinction matters because this is not a fresh call for alternative development sites. The councils say proposals for new sites will not be considered at this stage. Instead, comments made during the consultation will accompany the plan and its evidence base when it is submitted to the Secretary of State for examination by an independent Planning Inspector.
The updated plan identifies a requirement for more than 50,000 new homes between 2024 and 2045. Around 37,000 are already accounted for through existing permissions and allocations, according to Cambridge City Council. The document also addresses employment growth, sustainable transport, climate resilience, biodiversity and the infrastructure needed to support a growing population.
Housing growth meets infrastructure pressure
The scale of planned growth makes infrastructure one of the most consequential parts of the debate. Water supply is particularly sensitive in Cambridgeshire, where development ambitions have repeatedly collided with concerns about limited resources and environmental pressure.
A recent Guardian report highlighted water shortages across parts of eastern and south-eastern England, including Cambridgeshire, and examined the difficulty of reconciling national housing targets with constraints on supply. The Greater Cambridge plan itself treats water, sewage and transport as central infrastructure questions rather than secondary details.
For local communities, that means the consultation is about more than the headline number of homes. It also concerns whether growth can be supported by services, transport networks and environmental safeguards in a way that is workable over the long term.
The current version follows years of consultation and evidence gathering. More than 1,280 people and organisations submitted over 8,400 comments during the previous draft consultation, which ran from December 2025 into January 2026. Those responses were published alongside updated evidence before councillors approved the plan for this final stage.
What happens next
Once the consultation closes on 25 September, Cambridge City Council and South Cambridgeshire District Council will prepare the submission package for government. The independent examination will then consider whether the plan meets legal requirements and national tests of soundness.
If ultimately adopted, the Local Plan will become the statutory development plan for Cambridge and South Cambridgeshire and will guide decisions on future planning applications across the area.
For residents and organisations considering a response, the practical point is that this final consultation is narrower than earlier engagement. Comments need to address the proposed plan as submitted and the formal tests it must pass, rather than reopening the entire process from the beginning.
