For main contractors and Tier 1 suppliers on public work

Supply Chain Partnership
Align your SME suppliers to support your work winning. No cost to you, little effort, no obligation.

Why your SME supply chain wins you work

Evidence that is often outside your scope
Tenders score public value on project issues beyond your own works. Your SME partners hold that evidence.

SME spend targets
Projects carry SME spend targets, and buyers must now reduce barriers for SMEs.

Best placed to deliver programme commitments
Your SMEs deliver much of the work, and many of the public value commitments you make.

What benefits can main contractors expect?
