Green Deal and ECO evaluation

This collection brings together all research relating to Green Deal and Energy Company Obligation (ECO) evaluation.

In order to evaluate the Green Deal and ECO, DECC has commissioned a number of research reports exploring a number of aspects of the Green Deal and ECO. These include reports on the Green Deal and ECO customer journey, Green Deal assessments and the Green Deal and ECO supply chain.

Green Deal assessment research

This is a series of survey reports conducted with households who have had a Green Deal Assessment in order to find out more about the experience, and what households have done and plan to do since having the assessment. DECC first conducted three “assessment surveys” in 2013. The combined survey report, published in January 2014, is available at:

Green Deal customer journey surveys

Further waves of research, referred to as “customer journey surveys”, have been conducted since then through a longer survey which again explore the assessment experience, and what households have done and plan to do since having the assessment. The latest wave, published in March 2015, is available at:

Working Paper: Feasibility study on Green Deal & ECO customer behaviour

A working paper summarising scoping work undertaken to (i) identify knowledge gaps in relation to consumer behaviour following the installation of Green Deal measures and how such behaviour impacts on the assumed benefits (in terms of reduced energy use, fuel bills or carbon saved) of installing energy-saving measures (ii) identify feasible research options that would seek to address the identified knowledge gaps and (iii) identify options for linking to other research efforts within and outside government to reduce costs and ensure value for money.
