About the Energy Saving Opportunity Scheme Examination

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. Please contact the Training Team if you have any special needs.

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’. This will be available to access for 14 days from the last day of your course.

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 right answer – candidates should note that some questions offer options for ‘all of the above’ or ‘none of the above’ so the questions should be read carefully. Questions with more than one option ticked will be marked as wrong. The questions will cover the whole syllabus, some of which is only covered in the pre-reading. 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 login 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.

Notification of examination results

All candidates are notified of the result of the examination by email. Such notification will normally be sent within two weeks of the examination unless the result is the subject of a complaint.


Candidates are offered the opportunity of one re-sit at no charge if they fail the exam. The re-sits are arranged with a member of the Training Team. If the re-sit is not successful we recommend the candidate takes further training before trying again. If they would like to re-sit a further time, then there is a charge associated with this. There is no limit to the number of times a candidate can re-sit.
