Details

This research aims to understand how effective energy audits and reporting, including the Energy Savings Opportunity Scheme (ESOS), have been in identifying and delivering energy efficiency savings across organisations. These reports form part of the evidence base for the Post Implementation Review (PIR) of ESOS. The full PIR is attached along with the other documents on this page.

The study ran from 2017 to 2019 and included:

Phase 1

  • literature and evidence review
  • 25 qualitative interviews and 6 workshops with stakeholder groups
  • in-depth case studies with 3 stakeholder groups

Phase 2

  • telephone survey of 503 complier organisations
  • 10 qualitative organisational case studies with ESOS organisations and small and medium-sized enterprises
  • 33 in-depth interviews with stakeholders
  • linking of ESOS compliance data with secondary data
  • modelling of the energy and emissions savings attributable to ESOS

Further information on the activities in the Phase 2 report is included in the Phase 2 technical report. The data tables show results from the 2018 survey of ESOS-obligated organisations.

The research follows an earlier interim evaluation, conducted between 2015 and 2017.

The evaluation was undertaken by Ipsos MORI Ltd in partnership with the Carbon Trust and University College London.
