The Energy Saving Opportunity Scheme (ESOS) is the UK Government’s approach to implementing the European Union’s (EU) Energy Efficiency Directive.

A brief introduction

The Energy Saving Opportunity Scheme (ESOS) is the UK Government’s approach to implementing the European Union’s (EU) Energy Efficiency Directive. The Directive require all of the 28 member states to introduce a programme for the regular auditing of large organisation and their corporate groups. The Directive forms the principle tool to support the EU’s overall target to save 20% of primary energy consumption by 2020. Link to DECC guidance (PDF). The first Phase of ESOS covers 6.12.11 to 5/12/15. Two further phases are currently known with compliance dates of 5/12/19 and 5/12/23.

Why ESOS is important to you and not just another hoop or tick box?

Typical ‘free audits’ whilst useful in their own right, are often aligned to the provider. These ‘incentivised’ audits are most likely to result in proposals for new equipment via supply, install, and potentially operate contracts. Where this approach falls down, is that ‘best value’ energy efficiency options are often missed or ignored as they hold little value to the ‘free audit’ provider.  ESOS requires a measure of financial expenditure and a Director to sign off the final submission. Engaging both the general Board and CFO, the visibility of ESOS and the impartiality of recommendations for saving energy, money and enhancing business resilience is a valuable opportunity to deliver change into your organisation.

Lead Assessor Requirements

ESOS requires a compliant energy audit to be conducted, which must be carried out or approved by a recognised Lead Assessor. The Lead Assessor must also review and sign off on the ESOS Assessment as a whole, as does a board-level Director (or equivalent Senior Manager).

Non-Compliance Penalties

If you should fail to notify the Environment Agency (EA) of compliance with ESOS, or your records are not sufficient to demonstrate compliance, the EA may issue an enforcement, compliance or penalty notice on your organisation. This may result in fines up to £50,000 or £500 per day until compliance is attained.

Measuring Total Energy Consumption

This must include energy from buildings, transport and industrial processes and cover 90% of total consumption. The data must cover a minimum 12 month period (the ‘reference period’). If data is already held as part of previous ESOS compliant activities, this may be used if valid and is from no earlier than 6th December 2010 and no more than 24 months before the ESOS audit start date. Existing DECs and Green Deal Assessments can both be used as part of the route to compliance.

What you have to do

A compliant assessment need to be submitted to the Environment Agency by the 5th December 2015. If your organisation is already covered by ISO50001, this is deemed to comply with ESOS requirements.
