Research and analysis: Examining potential bias in the sampling methodology for the Green Deal assessment survey

By HM Government

This study was commissioned by the Department of Energy and Climate Change as part of the evaluation of the Green Deal and Energy Company Obligation (ECO) programme, and was conducted by Professor Patrick Sturgis (University of Southampton) and Dr Ian Brunton-Smith (University of Surrey) under the guidance of ICF International.

The objective of this study was to assess independently the robustness of the Green Deal Assessment research sampling approach using the second wave of the Green Deal Assessment Surveys to understand whether there were biases in key survey variables. In addition to considering whether and how future surveys could be refined to reduce any bias as a result of the clustering of addresses or whether a different approach is needed for further household customer surveys that may be commissioned by DECC in the future.
