Review of the bioresources market

Following PR19 and our first ‘Bioresources Market Monitoring Report’ we launched our review of the bioresources market on 19 October 2020. The review is a more comprehensive look at the market and considers issues such as:

  • the scope for bioresources competition under the current market model – amongst other things, this will help to inform our future monitoring of the market;
  • the current barriers to competition and the development of the market;
  • different forms of competition / market models; and
  • options and the steps needed to achieve these market models and the barriers needed to achieve them.

The review will inform how we regulate in future, including our approach at PR24. In this page, we provide updates on this work.
