Supply chain

We spend £6 billion a year buying goods and services from more than 180,000 suppliers around the world. We aim to select partners that meet high standards on ethical business conduct, employment practices, human rights and the environment.

Our approach includes: identifying social, ethical or environmental supply chain risks; communicating our expectations to suppliers; and engaging more closely with suppliers whose products and services or location could present a higher risk to WPP or our clients.

We evaluate all potential new suppliers against a set of business requirements, including sustainability, before they can become a WPP supplier.

Suppliers and business partners are asked to sign a copy of the WPP Code of Business Conduct which includes requirements relating to labour practices (such as wages, anti-harassment and discrimination and health & safety), human rights (including no child, forced or bonded labour), social impacts (such as anti-bribery and corruption) as well as other sustainability criteria.

We work with Sedex, the not-for-profit supply chain organisation, to assess risks in key areas of our supply chain such as advertising production and data collection.

Our clients expect us to manage social and environmental risks in our supply chain. By working with suppliers and improving oversight of standards in key areas, we can meet client expectations, align our procurement with our values, create efficiencies and reduce costs to the business
