Boilers and Pressure Vessels

Installation Permits


Licensed contractors and equipment owners who are planning to install, operate, or perform maintenance on regulated boilers and systems require a permit. Pressure vessels do not require an installation permit.

Examples include:

  • hot water or low pressure steam boilers with a heating surface area exceeding 3 m2;
  • high pressure steam boilers with a heating surface area exceeding 2 m2; or
  • hot potable water heaters exceeding 120 kW or 400,000 BTUs/h.

Pressure vessels don't require an installation permit, but some, including propane storage tanks, require an operating permit.

  1. Register your boiler or pressure vessel before applying for an installation permit. Not all equipment requires registration, but many do. Once your design registration is approved, you will receive a Canadian Design Registration Number (CRN) that is needed for the installation permit.
  2. Apply and pay for a permit through your account or by filling out one of our online forms for boilers or refrigeration. If you use one of these forms, you will have to submit payment separately through mail, or by calling us.
  3. Once your application is approved, Technical Safety BC will issue a permit number.
  4. Once the installation is completed, you can then submit the Boiler and Refrigeration Declaration form, which can also be found in your account.
  5. Technical Safety BC will process the request and determine if a further physical assessment is needed.

Often, the scope of work changes over the course of a project, affecting the value of the permit. If this is the case, a permit amendment must be submitted. A permit for the final value and scope of work must be in place before requesting for a final inspection. Undervalued work may be subject to enforcement action.
