Complying with ESOS
What do I have to do to comply with ESOS?
In simple terms, an ESOS Assessment requires participants to do three things:
1. Measure your total energy consumption
You must measure your total energy consumption across your buildings, transport and industrial activities.
2. Conduct energy audits to identify cost-effective energy efficiency recommendations.
You must ensure that at least 90% of your total energy consumption is subject to an ESOS
compliant energy audit, a Display Energy Certificate, a Green Deal Assessment or a certified ISO 50001 Energy Management System during each phase of the scheme.
For the first phase of the scheme, you can use any energy auditing activity dating back to
December 2011 to support compliance (for example, the Carbon Trust Standard) provided that it meets the minimum standards required of ESOS Energy Audits.
Unless your total energy consumption is covered by a certified ISO 50001 Energy Management System, you must ensure that your ESOS Assessment is conducted or reviewed by a qualified Lead Assessor (the lead assessor may be an in-house expert or external consultant).
3. Report compliance to the Environment Agency (as the scheme administrator)
By 5 December 2015, you must notify the Environment Agency (as the scheme administrator) that you have complied with the scheme.
Prior to notifying the Environment Agency, you must ensure that your ESOS Assessment has been reviewed by a Board-level Director and approved by a Lead Assessor.
Participants are not required to implement energy efficiency recommendations identified by their ESOS Assessments. However, they will only achieve the financial benefits that arise from avoiding energy waste if they do implement cost-effective recommendations identified.
What if I am an SME or public body?
Although SMEs or public sector bodies are not required to participate in ESOS, they could still benefit from voluntarily meeting the ESOS requirements. ESOS provides a framework you may wish to use to help you identify energy efficiency opportunities, e.g. you may wish to use using a qualified ESOS Lead Assessor to undertake energy audits of your operations.
