Power Engineer: Interim certificates

Interim certificates

An interim certificate of qualification entitles an engineer to exercise the full scope of a given Power Engineer certificate, for a limited period of time.

The purpose of an interim certificate is to assist companies through a period of time where they are unable to retain the services of a required class of Power Engineer.

Categories of interim certificates

There are two categories of interim certificates for Power Engineers.

Category A: this interim certificate is issued if the boiler capacity of a plant has increased, or a Power Engineer needs more time to complete the required examinations for their certificate. Category A interim certificates can remain active for up to 12 months and can be renewed once if the Power Engineer has attempted to pass their certification exam.

Category B: this interim certificate is issued if there are special circumstances in the plant such as illness, extended vacations, or emergencies. It can remain active for up to 60 days and can be renewed once for 30 more days.


A chief engineer of a plant may apply for an interim certificate on behalf of a Power Engineer. If there is no chief engineer, then the owner of the plant may apply instead.

In addition, the Power Engineer must:

  • Hold a Power Engineer certificate that is one class lower than required for the relevant position
  • Be employed in the plant or an equivalent plant for a period of at least 12 months

If you want to apply for a Category A interim certificate because your Power Engineer needs more time to complete the required Class certificate, they must also have completed at least one exam towards their Fourth or Third Class certificate, or at least two exams towards their Second or First Class Power Engineer certificate.

How to apply

You can apply for an interim certificate by following these steps:

  1. Submit a completed application form via email.
  2. Pay a fee.

You can expect an average processing time of four weeks, from the time you submit your completed application form to when your certification is confirmed. During this time, Technical Safety BC will reach out to you about fee payment.

Receiving your certificate

Technical Safety BC issues interim certificates via mail or email, depending on preference. The certificate will be issued to the chief engineer or owner of the plant.
