Part L 2021 was introduced in June 2022 and is intended to be an interim step towards the introduction of the Future Homes and Buildings Standard in 2025. The headline objective is reduction of regulated carbon dioxide emissions by 30 % in new dwellings and 27 % in new buildings. 

The training course covers the key requirements and guidance set out in the Approved Documents, which have been comprehensively reorganised, with an emphasis on the changes relative to Part L 2013. 

Since it is aimed at CIBSE Certification registrants it primarily covers non-domestic applications, with only passing reference to domestic applications.

Delegates will not be excluded if they haven’t undergone training with CIBSE, although are expected to have either taken training with another provider or have a sufficient knowledge in order to sit the exam.  

Please note the Part L 2021 Update Exam is included with this purchase and will be assigned to you upon completion of the course. Please do not try to purchase this separately.

Training is not mandatory and as such you can purchase the exam only.

Your course will be hosted on Microsoft Teams if ‘Remote’ or at our headquarters in Balham, London if ‘Face-to-face’. Joining instructions will be included in the booking confirmation sent upon successful booking of a live course. You will receive an email with the subject line ‘Welcome to MyCIBSE Learning’ from [email protected] once your place has been confirmed, where you can create a password to access your ‘MyCIBSE Learning’ portal. Please note this portal will host the exam only, which will be assigned to you on the day of the course.

  • The training course is for those already registered with CIBSE Certification as a Low Carbon Consultant (Design), to help prepare for the Part L 2021 update exam, which LCCs are required to pass to demonstrate maintained competence and to remain registered
  • It covers the following Approved Documents:
  • Volume 2: Buildings other than dwellings, 2021 edition – for use in England 
  • Building Regulations are a devolved responsibility in Wales, Scotland and Northern Ireland. This course covers only the Regulations applicable to England, however, for CIBSE Certification compliance purposes passing the Part L 2021 update exam is a requirement as the Registers cover all regions.

  • The course does not cover the use of approved compliance software.

    Please note that existing Low Carbon Consultants (Design) may prefer to attend instead the ‘Part L – one-day course, which is more comprehensive and also covers domestic applications.

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

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 will cover the Part L regulations including the 2021 updates. Some of the questions will require good engineering judgement. 

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.
