To maintain registered approval status:
Hold an active AEE Certified Energy Manager (CEMI) or Certified Energy Auditor (CEAI) certification (international (I) version based on SI units)
Hold current Professional Indemnity Insurance (PII) relevant to energy auditing work or be covered by your employer
Be able to demonstrate PAS 51215:2014 competencies including transport energy auditing (CEMI/ CEAI training typically includes an introduction to ESOS and also transport auditing techniques, depending on where training has been carried out) and be familiar with PAS 51215:2025 BSI standard
Commit to a minimum of approximately 1 day of ESOS-related CPD per year
If an ESOS Lead Assessor approved professional is for any reason rendered unable to perform the duties required of them as a certified professional, they will notify the UKAEE immediately at esos@ukaee.org.
Renewal of CEMI or CEAI: If your CEMI or CEAI certification lapses or is terminated, you will be given a 6-month grace period to renew. If renewal is not completed within this period, you will lose your ESOS approval and be removed from the ESOS register. Reinstatement after this point requires a full new application including exam and fee.
Continuing Professional Development: If your CPD is not up to date or does not meet the requirements, you will be contacted to rectify this within 30 days. Subsequently, if your CPD remains incomplete you will be notified of your removal from the ESOS Lead Assessor register and your ESOS approval revoked.
Professional Indemnity Insurance: If your PII lapses or is terminated, you will be given 30 days to reinstate cover. If unresolved, you lose your ESOS approval and will be removed from the register.
Reinstatement: LAs removed for CPD, PII, or compliance failures may apply for reinstatement within 3 months by submitting relevant evidence (CEMI/CEAI certificate, PII certificate, CPD records as applicable) to esos@ukaee.org. Reinstatement is approved by the Chapter President. The £100 reinstatement fee applies.
All registered UKAEE ESOS Lead Assessors are required to confirm their agreement to this Code of Conduct annually via the UKAEE ESOS Lead Assessor Annual Compliance Confirmation form. Completion of the form constitutes formal acceptance of the Code of Conduct and carries the same weight as a signed declaration. Responses are timestamped and retained by UKAEE as evidence of compliance. Confirmation must be renewed annually as part of the registration renewal process.
All ESOS Lead Assessors must ensure any complaint against them is reported back to UKAEE. Any AEE member, company, or individual who witnesses a breach of the Code of Ethics in regards to an AEE-registered ESOS LA is encouraged to file a complaint with the AEE certification board. Complaints should be submitted to: international@aeecenter.org with esos@ukaee.org in copy (with subject including 'Complaint')
The complaint process includes the following steps:
The certification board will gather all available information for internal review
If a potential violation is identified, the board will interview both the complainant and the certified professional
The certified professional will have full opportunity to respond and provide evidence
The board will conduct an independent and impartial hearing
If a violation is found, the board may suspend or revoke certification by a two-thirds majority vote
