This statistical release is intended to present a record of all previously developed land and buildings in England that may be available for development, whether vacant, derelict, or still in productive use. The rate of return from local authorities for 2011 was low at around 50%. This raw, site-level data reported to the Homes and Communities Agency (HCA) by local authorities has been collated into the above site list with no validation. Due to the limited response, analyses and reports were not compiled. In the interests of openness and transparency HCA is releasing currently held NLUD-PDL data.
Being on the dataset does not necessarily mean that a site is available for development. The data provided should be treated with caution. No indication of potential constraints to development is factored into the figures; for example flood risk and contamination could rule out certain types of development such as housing or employment floor space. Further viability considerations such as location and local market conditions are also important in interpreting the data.
