Register of Professional Energy Consultants (consultants questions)

What are the requirements to be registered as a professional energy consultant?

All consultants on RPEC are required to demonstrate their competence in relevant skills, technologies and sectors. This is achieved by a combination of assessment of client reports against the stated criteria and a telephone interview. Both elements of the assessment are carried out by other qualified consultants by means of a peer review process.

The usual level of qualification expected of a Registered Consultant is Chartered status or equivalent. If an applicant is not already Chartered, he/she is strongly recommended to acquire Chartered status in a relevant discipline such as Chartered Energy Manager or Chartered Engineer. As part of the application process, consultants can also apply simultaneously for Chartered status with the EI. For those without relevant accredited qualifications (where necessary) this will be via the Individual Route to qualification. This requires demonstration of how your experience as a consultant meets the Learning Outcomes for the relevant level of qualification required for Chartered status. Whether applying for Chartered status or not, this same process will be required if a consultant chooses only to demonstrate equivalence to Chartered status. More advice on this option is available from our membership department

How do I apply?

You will need to complete an application form, provide supporting evidence of your claimed competences through examples of client reports and undergo a formal assessment by a Validation Panel and telephone interview.

What happens after the application process?

Following the telephone interview, there will be one of three outcomes:

1.Invitation to join RPEC with no amendments

The evidence provided show you meet the criteria to join RPEC and you hold the grades of experience contained within the self-assessment section of your application.

2.Invitation to join RPEC with amendments

The evidence provided show you meet the criteria to join RPEC with amendments to the grades of experience contained within the self-assessment section of your application in one or more topics.


The evidence provided show you did not meet the criteria to join RPEC.

How does my company apply?

There is no provision in RPEC for accreditation of companies. Within a consultancy, employees wishing to join should either apply as individual Registered Consultants or join a mentoring scheme towards eventual registration.

Do I have to be an EI/ESTA member to join?

It is not a requirement to be an EI/ESTA member but we would strongly recommend that you are for two reasons:

  • You will benefit from the additional qualification that membership provides (including Chartered status in a variety of specialisms from the EI and networking with other independent consultants from ESTA)
  • You will receive a substantial discount on the annual registration fee.
Who will be assessing consultants to go on the Register? Can I become involved in this?

The Validation Panel will be populated with a number of consultants who have volunteered their time to make the assessment process as robust and fair as possible, as well as ensuring that consultants are recognised by their peers.

We very much welcome assistance from anyone wishing to take part in this process, for which training will be given. Please apply to

Why does the application form make a distinction between independent consultants and those affiliated to equipment manufacturers and suppliers?

We believe that consultants providing energy efficiency advice may be either independent or working within organisations that also supply solutions and that independent advice can be provided by either.

We would not wish those giving good energy efficiency advice to be excluded from RPEC by requiring all consultants to be independent. However we believe that it is fair that the user of the Register is aware of any such ties so that they can make a more informed decision about the independence of the advice received.

To achieve this, we recommend that consultants who are not independent declare this on their application, make this clear to their potential clients and ensure that they are conforming to all the requirements of the Code of Professional Conduct.
