The exam is 'Open Book' - texts allowed are:
  • Approved Documents L2A and L2B: CLG guide
  • The course handouts (for those who have attended the CIBSE training)

Only hard copy texts are allowed; documents loaded onto laptops are not allowed in the exam

There are 50 multiple choice questions (worth two marks each). The exam is marked out of 100 and the pass mark is 70%.

The time allowed is 90 minutes.

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. Some of the questions will require good engineering judgement. You will need a calculator.

If candidates have not prepared thoroughly by completing the pre-reading and understanding the training course, you may find it hard to finish the exam. Please let us know in advance if you have any relevant special needs or requirements.

About the LCEA examination 

Delegates will sit the same examination as on day two of the training, with an additional element of a simulation exam sat on the third day of the training. Where two DEC certificates are to be produced.  Both elements must be passed.

The third day of the training requires the use of a laptop which runs the Windows operating system and the Office suite, (the software does not run on Apple or Android based devices). Ensure that the ORcalc software has been downloaded onto the laptops prior to the course. This link as well as other information is detailed on the following document reading list.  Please ensure that the laptop enables 3rd party software to be downloaded in case of any issues.

If you are unable to bring a laptop with you for any reason, please contact in advance of your training course.  

Notification of examination results

All candidates are notified of the result of the examination by either letter or email. Such notification will normally be sent within 2 weeks of the examination unless the result is the subject of a complaint.


Delegates are offered the opportunity of one complimentary re-sit if they fail the exam. The re-sits are arranged with the training manager. If the re-sit is not successful we recommend the candidate takes some further training before trying again. If they would like to re-sit an additional time then there is a charge associated with this. There is no limit to the number of times a candidate can re-sit.


You can ask CIBSE to make an enquiry into your examination results if you think:

  • A mistake has been made working out the result
  • There are issues with the exam questions
  • Security has been breached

Appeals should be made in writing at least 2 weeks from the date the results are received and must be made in writing to CIBSE. The paper will be reassessed by a suitably qualified person and member of CIBSE who has not been involved in the original marking process. You will be informed in writing of the outcome of the appeal.
