Western Australia (Building and Energy) Builders Licence Guide
If you want to legally carry out building work in Western Australia, you must hold the appropriate registration issued by Building and Energy WA, which operates under the Department of Mines, Industry Regulation and Safety (DMIRS). Builder licensing in WA is regulated under the Building Services Act and applies to individuals and businesses performing residential or commercial building work.
A WA Builders Licence confirms that a person or company meets strict standards of competency, experience, and financial suitability to operate within the Western Australian construction industry. Without the correct registration, it is illegal to contract or perform regulated building work.
What is a WA Builders Licence?
A WA Builders Licence is a legal authorisation that allows a person or business to contract, manage, supervise, and carry out building work in Western Australia.
Licences are issued by Building and Energy and are classified based on:
- Type of building work
- Scope of services offered
- Technical competency
- Level of experience
The licensing framework exists to protect consumers, regulate building standards, and ensure that construction work is completed safely, professionally, and in accordance with WA legislation.
Who Needs a Builders Licence in Western Australia?
Any person or business performing building work valued over $20,000 (including labour and materials) must hold an appropriate WA Builders Licence.
This includes:
- Residential builders
- Renovation and extension contractors
- Commercial builders
- Trade contractors operating independently
- Construction supervisors
- Company directors contracting work
If you quote, manage, or contract building work, you must be registered, even if subcontractors perform most of the physical work.

Unregistered builders often cannot legally enforce contracts or recover payments.

Mutual recognition does not guarantee approval.
Why Building and Energy Takes Licensing Seriously

- Regulate industry conduct
Building and Energy actively audits contractors and investigates complaints across the construction sector.
In Summary
