“We build effective supplier Partnerships across a wide range of industry products and services to support us in delivering the growth and quality of our critical digital infrastructure for the UK.

Roger Keenan
Chief Finance Officer

Cornerstone relies on an end-to-end Supply Chain of over 450 Partners, with the common objective to achieve our business strategy to provide world-class output while fostering and developing strong partnerships with strategic suppliers. As a company, we engage with partners who can work within established industry service levels, providing quality deliverables and assisting us in meeting and exceeding the expectations of our customers. Our partners share and deliver Cornerstone's core values, understand the importance we place on conducting business openly, honestly, have integrity and "ALWAYS" put safety first.

Our Life Saving Rules - known as Salus - named after the Roman Goddess of Health and Welfare of both the individual and the state who later became the protector of Personal Health and Wellbeing - have been developed to keep everyone working on our sites safe.
