This data science project was delivered to Hackney Council as part of the S2DS London programme
Hackney Council provides social housing to over 20,000 tenants. As with other social housing providers, some tenants fall into arrears, and this is likely to become more acute following the rollout of Universal Credit. Of all new arrears cases however, only 16% go on to become the long-term cases that account for the majority of money owed. Currently, Hackney Council has no way of identifying which arrears cases are likely to belong-term, so all cases are treated equally.

A team of four data scientists delivered an automated data science pipeline, covering the cleansing of raw data, the creation of new features within it, and the training and assessment of models in an easily amendable and scalable way.
Furthermore, the combination of factors that led to either high or low arrears risk scores were identified, allowing for the definition of risk groups, providing insights into how to improve the tenants’ situation. Finally, the model for predicting whether new cases of arrears will be long or short-term can help the council prioritise interventions, improving allocation of council resources.
The council now has a model to drive a data driven approach to understanding rent arrears and associated risks, helping them to better prioritise those that need more support in effectively managing their rental payments. It is hoped that this will facilitate a considerable reduction in the risk of long-term arrears cases, supporting both tenants and the council.
"The project has demonstrated that moving towards data-driven management approaches doesn’t have to involve huge levels of up front investment."
