Indicator for housing quality

The Welsh Government are trying to improve the evidence base they use for supporting policies in housing, energy efficiency and fuel poverty. Currently, evidence on housing conditions has relied on data from the Living in Wales Property Survey 2008 which can no longer represent a current view of housing conditions in Wales. Better evidence is needed to target policies and resources more effectively to improve the housing conditions of households that stand to benefit the most. These strategies and policies aim to improve the living conditions by making homes warmer, better quality and, where appropriate, more accessible.

The strategies affected are:

  • The Welsh Housing Quality Standard
  • The Fuel Poverty Strategy
  • The Housing (Wales) Act 2014 Part 1 arrangements for landlord licensing
  • The Property Improvement Loan fund
  • The Framework for Action on Independent living
  • Prosperity for All: the national strategy (Housing is one of the five priority areas)

The need

Welsh Government have identified nine key areas such as Energy Efficiency to improve the quality and coverage of their evidence. The campus are looking for a methodology which can be used in multiple scenarios for filling gaps in data. We will start by using the EPC data to test multiple algorithms, then as additional data is made available by DaaS, we will combine multiple sources to predict missing values for the unknown dwelling stock in Wales.

Impact

Filling the gaps in missing evidence will enable Welsh Government to make better decisions about their housing policies.

Data science

Both machine learning and deep learning techniques will be employed to find a working methodology.

Stakeholders

  • Welsh Government
  • Office for National Statistics (ONS) Sustainable Development Goals team
  • ONS PPD team

Code and outputs

  • A report will be published on the Campus website once the project is complete

Delivery

  • August 2018 Use prediction of energy performance to identify an algorithm capable of filling the gaps
  • October 2018 Move to DAP
  • November 2018 Get access, and audit data sources on DAP to replace the significant variables used in predicting energy performance
  • November 2018 Predict the energy performance for the other 52% of housing stock in Wales
  • December 2018 Validate the algorithm by applying it to other variables of a different format
  • Future Try same techniques on another key area identified by Welsh Government
  • Future Agree next steps with SGD team
