Cambridge Centre for Housing & Planning Research


Cambridge Centre for Housing and Planning Research developed a simple model to estimate the impact of charging different CIL and S106 rates on the economic viability of development. The model has potential to assist local authorities in modelling the impact of different CIL and S106 rates on the economic viability of development across their area.

CCHPR designed this project to further develop the model for local authority use. Working with a sample of local authorities to test and refine the model, the model was developed with a view to eventually making it publicly available for use by local authorities to assist in developing their new CIL and S106 charging frameworks. This would transfer our academic knowledge and expertise into a tool that can be used by local authorities in policy and practice.

The changing delivery of planning gain through Section 106 and the Community Infrastructure Levy

The aim of this research was to consider the issues shaping the delivery of planning obligations through S106 and to explore the potential impact of the new Community Infrastructure Levy (CIL), particularly on the delivery of affordable housing.
