APEL Route to become a Low Carbon Energy Assessor (LCEA) Air Conditioning Inspector to produce Air Conditioning Reports

CIBSE Certification operates the APEL (Approval of Prior Experience & Learning) Route to certification.  This is a fast, low cost route that recognises your prior experience and learning as an alternative to taking a specific Energy Assessor qualification and can provide certification to the highest quality via an application process.

The Pre-APEL is a FREE assessment of your 2 years of full time equivalent experience in the last 5 years and counts towards your main APEL form.  You will need to demonstrate that you have a minimum of 2 years of equivalent full time substantial experience in the past 5 years in designing, installing (including commissioning), or maintaining air conditioning systems; Level 4 for complex systems or Level 3 for simple systems.  

Register and submit your AC Pre-APEL application here.

If you pass the initial screening of your Pre-APEL you will be able to progress to the full APEL application process.

The Air Conditioning APEL application consists of two stages to achieve certification.

STAGE 1 – Complete the full APEL form online, submitting the following:

1. Proof of Identity –Submit a copy of your passport or driving licence (if for any reason you cannot provide a copy of one of these documents please contact us for further information).

2. Statement & CV – The statement and CV that you have already provided for your Pre-APEL should be submitted again with your main application.  However, if you have been asked at the Pre-APEL stage to amend either of these at the main APEL stage, you should submit a new CV and you will be able to amend the statement. If you have chosen to bypass the Pre-APEL stage you will need to amend both your CV and statement at this stage and pay the assessment fee without your CV and statement being pre-screened.

3. Insurance –Submit an up to date copy of your employer’s Professional Indemnity Insurance (PII) certificate (minimum £500,000.00 for Level 4 and £50,000.00 for Level 3 Only applicants).  You also need to provide a copy of your employer’s Public Liability Insurance (PLI) certificate (minimum £1,000,000.00 for both levels 3 & 4).

4. Membership –Submit a copy of your current professional membership’s certificates if applicable.
