Our values

Our values define who we are, what we stand for, and how we behave.

They guide how we work with our clients and each other, inform the type of work we do, and hold us accountable to do our best. They govern our actions and determine our success.

The trust that our clients, communities and our people place in PwC, and our high standards of ethical behaviour, are fundamental to everything we do. 

Our Code of Conduct is based on the PwC Purpose (to build trust in society and solve important problems) and a core set of shared values. The Code sets out a common framework around how we are expected to behave, do business and to do the right thing. This includes Speaking Up if we come across a situation that is inconsistent with the Code or our values.
