This document summarizes a presentation given at the Impact of Infrastructure 2012 conference in London. It discusses the shift towards a more demand-driven, market-based approach to infrastructure for the voluntary sector ("marketisation"). Key points addressed include the context of declining funding and changes in expectations from funders, what marketisation entails, emerging models like the Big Lottery Fund's focus on impact and legacy, and issues that this transition raises for customers, suppliers, and those shaping the emerging market system. Attendees were then asked to discuss in groups their experiences with and needs regarding these changes.
