Key Areas

The Energy Savings Opportunity Scheme (ESOS) is an energy assessment scheme that is mandatory for large organisations in the UK with more than 250 employees, turnover in excess of €50m and an annual balance sheet total of €43m. The Environment Agency is the UK scheme administrator.

On 26 June 2014, following a consultation process in 2013, the Department for Energy and Climate Change (DECC) published the ESOS Regulations 2014, which give effect to the scheme.

This course is designed for existing CIBSE Low carbon Consultants (LCC) who wish to progress to become an ESOS Lead Assessor or those who wish to gain a better understanding of ESOS.

The course is intensive and requires a high level of knowledge. To be assessed for the ESOS Lead Assessor you need to be on the LCC Register.  To assist you in this self-assessment CIBSE provides the following information:

  • ESOS Lead Assessors need to demonstrate the competencies defined in PAS 51215.  The majority of this has already been assessed when joining the CIBSE LCC Register.  The ESOS specific assessment focuses on knowledge and understanding of the ESOS Regulations and guidance.

  • In preparation for this course and assessment you should be familiar with the ESOS Regulations 2014 and the DECC Guide to ESOS

  • There is an examination at the end of the day and those wishing to progress to become a Lead ESOS Assessor will need to complete and pass the exam. It is a multiple choice exam of 30 questions and is time limited to 45 minutes.

  • Please note that to be placed on the ESOS register you also need to complete an application form and submit a current CV so that your relevant experience can be assessed.
