Repair estimates and authorizations

| Industry bulletins

Ensure you know and understand what you need to do as a service and repair business when it comes to repair estimates and authorizations. The Automotive Business Regulation (ABR) sets out specific regulations regarding repair estimates and authorizations in Sections 31.6, 31.7 and 31.8.

An authorization must be in writing and must have the following:

  1. the name of the consumer or the person acting on their behalf that is giving authorization;
  2. the date the authorization is given;
  3. a description of the work that the consumer or the person acting on their behalf is authorizing to; and
  4. the estimated total cost of the work described above and confirmation from the consumer or the person acting on their behalf to authorize the work.


  • If the consumer requests an estimate before starting any service or repair work to their vehicle, the business must provide an estimate as per ABR, Section 31.6(1).
  • If a consumer requests an estimate, the business operator must provide a written estimate that includes:
  • a description of the proposed work; and
  • the estimated total cost of the proposed work, including the cost of labour, parts and equipment. (ABR Section 31.6(2))
  • If an estimate cannot be provided because the business must first perform diagnostic work, then the estimate must state the estimated maximum cost of the diagnostic work, as per ABR Section 31.6(3).

To help businesses understand their obligations, AMVIC has created a service and repair estimate and authorization checklist to help you navigate service and repair scenarios. Remember, all service and repair businesses should understand what they are responsible for when it comes to providing estimates to consumers.
