Strengthening the Energy Savings Opportunity Scheme (ESOS)

Closed 28 Sep 2021

Opened 6 Jul 2021


This consultation is seeking views on proposed measures to strengthen the Energy Savings Opportunity Scheme (ESOS) to improve the uptake of energy efficiency measures, and increase the benefits for participating businesses.

This consultation follows on from the 2020 Post-Implementation Review of the scheme and welcomes views on the following options to improve the scheme:

  • Improving the quality of audits through increased standardisation of reporting requirements
  • The inclusion of a net zero element to audits
  • Requiring public disclosure of high-level recommendations by participants

We are also seeking views and evidence on two additional options that do not form part of the core proposals to improve the scheme:

  • Extending the scope of the scheme to include Medium-Sized Enterprises
  • Mandating action on audit recommendations
