Authority Monitoring Report
Monitoring is essential in order to establish what has been happening in Greater Cambridge; what is happening now, what may happen in the future and what needs to be done to achieve policies and targets.
Councils produce an Authority Monitoring Report every year, which reports on the previous monitoring year from 1 April to 31 March. It contains information about the performance of planning policies set out in the adopted Local Plan and Area Action Plans, and also provides a general portrait of social, economic and environmental conditions in the city.
The Authority Monitoring Report also assesses the Council’s progress in producing its Local Plan and Area Action Plans against the timetable set out in the Local Development Scheme. The annual publication of an Authority Monitoring Report (AMR) is a statutory requirement for all Local Authorities. The Greater Cambridge Shared Planning Service produces a joint report for Cambridge City and South Cambridgeshire District Councils.
We have now published the Authority Monitoring Report for 2024 to 2025. Older reports can be found in our Reports Archive.

Infrastructure Statements
We have produced a series of Infrastructure Funding Statements showing information relating to contributions secured, allocated, used and retained. These can viewed on our Developer contributions (Section 106) webpage.
Housing trajectory
A housing trajectory is used by Councils to calculate their housing land supply and also to demonstrate that anticipated housing delivery will meet or exceed their housing requirement.
We review the Greater Cambridge housing trajectory and housing land supply calculations annually and it is published in April.
The Greater Cambridge Housing Trajectory and Housing Land Supply Report (April 2026) concluded that we jointly had 5.6 years of housing land supply for the 2026-2031 period.
However, following the publication of the new National Planning Policy Framework and Housing Delivery Test results in August 2026, and in order to adopt a consistent approach to the monitoring of housing delivery in Greater Cambridge, we have published an Addendum that calculates the five year housing land supply for Cambridge and South Cambridgeshire individually.
The Addendum to the Greater Cambridge Housing Trajectory and Housing Land Supply Report (September 2026) concludes that:
- Cambridge has 2.72 years of housing land supply for 2026-2031, and
- South Cambridgeshire has 7.83 years of housing land supply for 2026-2031.
These figures will be applied when considering development proposals against the development plan and NPPF 2026 national decision-making policies.

Housing Delivery Test
The Housing Delivery Test (HDT) is an annual assessment of actual housing delivery over the previous 3 years, measured against the housing requirement for the district for that same time period. It was introduced in 2018, and is conducted by Government using information supplied to them by local authorities. National planning policy and guidance sets out the consequences of different results of the Housing Delivery Test.
The latest set of HDT results were published in August 2026. The result for Cambridge is 82%. The result for South Cambridgeshire is 148%.
There are therefore no consequences for South Cambridgeshire, however for Cambridge an Action Plan must be prepared as delivery is less than 95%, and a buffer of 20% also needs to be applied to the five year supply calculations for Cambridge as the HDT result is less than 85%.
