This document provides background information on a dissertation that examines the impact of local authorities on the use of long-term temporary accommodation in London. It finds that the number of households spending over two years in temporary housing is five times higher in London than elsewhere in England. The study evaluates three London boroughs' approaches to managing homelessness duties and allocating social housing, hypothesizing that policy implementation contributes to long stays in temporary accommodation. It aims to understand differences between boroughs and reflect on implications for national policy. Key questions guiding the research evaluate performance measurement, policy interpretation variation, and barriers to ending temporary accommodation stays.
