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 £44m and an annual balance sheet total of £38m. The Environment Agency (EA) is the UK scheme administrator.

The EA has recommended that companies implement a programme of regular energy audits as this will help them keep on top of ESOS compliance. With the ESOS Phase 2 deadline approaching are you ready to advise?

There are 30 multiple choice questions (worth two marks each). The exam is marked out of 60 and the pass mark is 70%. The time allowed is 45 minutes. Based on government guidelines, an additional 25% extra time is given for special needs. Time allowed is 57 minutes.

Once your attendance on the course has been confirmed you will have access to the exam via your CIBSE Online Learning Portal under the tab ‘My Learning’.

If there is any reason that you should not be able to complete the exam online, please contact a member of the training team at [email protected] to make alternative arrangements.

Multiple choice questions only have one correct answer – candidates should note that some questions offer options for ‘all of the above/below’ or ‘none of the above/below’ so the questions should be read carefully. Questions with more than one option ticked will be marked as incorrect.

The questions will cover the whole syllabus, some of which is only covered in the pre-reading. Some of the questions will require good engineering judgement. Some of the questions will require a calculation. You will need a calculator.

The exam is hosted via the CIBSE Learning Management System. Each exam is timed and will automatically log the candidate out once the time has ended. The CIBSE Learning Management System has a single sign on system forcing the candidate to log in with a username and password. Once the exam has been started the candidate is unable to pause or restart the exam and must be finished in the allocated time.

Although the exam is 'open book' it is not designed to allow candidates to look up all the answers - material allowed should be regarded as reference. If candidates have not prepared thoroughly by completing the pre-reading and understanding the training course, they may find it hard to finish the exam. CIBSE Training must be notified in advance of any relevant special needs or requirements.

Best practice advice for candidates sitting an exam:

  • Find a quiet, well ventilated, well-lit room so you can comfortably sit your exam  
  • Schedule a suitable time where you will have the least distractions (meetings, children, deliveries, etc.)
  • Check all your technology is working (computer plugged in, near WiFi hub, registration complete, etc.)
  • Put a do not disturb sign on your door, turn off email notifications, mute your phone, etc.
  • Check if there is pre-reading for the exam , if the exam is open book, and how much time you have.
  • Don’t get anyone else to help you with the exam as you are the one who will need the knowledge to practice.
