Annual submission requirements
- Submit a CPD record annually by when requested by the EI
- Complete a minimum of 5 CPD hours specifically related to ESOS each year

Recognised CPD activities for ESOS Lead Assessors
If you hold a Lead Assessor role under the Energy Savings Opportunity Scheme (ESOS), your CPD must directly relate to that function. Relevant ESOS CPD includes:
- Training on ESOS regulations, requirements, and compliance
- Learning about energy assessment methodologies and frameworks
- Developing competence in new areas of energy efficiency assessment
- Keeping up to date with changes to ESOS guidance and legislation
- Mentoring in techniques and contexts relevant to ESOS practice
- Participating in ESOS-focused conferences, webinars, or professional events
The Energy Institute provides an ESOS CPD Training Package specifically designed to help Lead Assessors meet their annual CPD requirements
Record your CPD
Maintaining an accurate, continuous CPD record is a mandatory requirement for all professional members of the Energy Institute.
To support you, the Energy Institute offers two ways to record your development. Whichever method you choose, your record should be kept current, reflect genuine reflection on your learning, and be ready to submit if requested as part of a CPD audit.
- mycareerpath® — the Energy Institute's free online platform, designed to help you plan, record, and reflect on your professional development all in one place. This is our recommended tool for keeping your CPD record up to date.
- CPD Record Template — if you prefer to work offline, you can download and use our CPD record template instead. Please ensure you update the date on the form to accurately capture your learning activities within the correct period.
Your CPD record should demonstrate:
- A variety of learning activities spanning different areas and formats
- Genuine reflection on what you learned and how it has benefited your practice
- Consistent, ongoing development rather than activity concentrated into short periods
- Breadth across professional practice, technical knowledge, and professional skills
- ESOS Lead Assessors: You must record your ESOS-related CPD using either the Energy Institute's dedicated ESOS CPD template, or a format that clearly identifies ESOS-specific CPD hours and learning objectives.
CPD monitoring and audit
The Energy Institute conducts an annual CPD monitoring exercise to ensure that professional members are meeting their development obligations. Each year, a proportion of members across all registration categories are selected to submit their CPD records for review by the CPD Panel.
Engineering registrants (CEng, IEng, and EngTech) and Professional Members (MEI) are subject to a minimum 5% annual sample, while at least 10% of Chartered Environmentalists (CEnv) or a minimum of 10 registrants, whichever is greater are selected each year. ESOS Lead Assessors are required to submit their CPD records annually without exception.
Being selected is a normal part of professional membership. The best way to be prepared is to keep your CPD record accurate, up to date, and reflective of your ongoing development throughout the year not just at the point of submission.
The CPD audit timeline
The Energy Institute's annual CPD audit runs across a structured cycle from August through to March the following year. The process begins in August, when the membership team downloads a fresh sample list from the EI database, confirms the audit cohort, and establishes the tracking framework for the exercise.
CPD record requests are issued to all sampled members in September, accompanied by submission guidance and supporting FAQs. Members are given until November to submit their records, with reminders issued throughout October and a final prompt ahead of the closing deadline. A CPD webinar is also held during this period to provide additional guidance and answer member queries.
Once submissions close, a randomly selected sample of records is allocated to assessors for individual review during December and January. Assessors complete their evaluations ahead of the Panel meeting, at which point their completed review forms are collated and a full panel pack including a statistics report, agenda, and assessor findings is prepared and circulated.
The CPD Panel meets in February to discuss the reviewed records, agree actions, and issue written feedback to members whose records were considered. Members who have failed to submit without an agreed deferral or extension are subject to lapsing of their membership or registration at this stage.
The cycle concludes in March, when the CPD Annual Report is presented to the Professional Development Committee (PDC) for sign-off, and all records and actions are formally archived.
Please note: Specific submission deadlines for the current audit cycle are confirmed each year. Contact the membership team or check your member communications for confirmed dates.
The monitoring process
If selected for monitoring, you will receive notification and must submit your CPD record. The CPD Panel reviews a proposition sample of CPD submissions and provides constructive feedback where appropriate.
The monitoring process:
- Ensures members maintain professional standards
- Provides constructive feedback on your CPD approach
- Supports your continued development
Consequences of non-compliance
Failure to submit within four weeks of the deadline will result in automatic removal from the ESOS Lead Assessor register.
