We advise that you are confident that you can fulfill all of the requirements for certification by visiting our CIBSE Energy Centre and following the various links on that page regarding LCC and 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.
