PR24 working groups and workshops

We are keen to engage with stakeholders to help us improve our approach to delivering the right outcomes; our approach to assessing costs; and our approach to assessing allowed returns at PR24. We have established working groups to engage with companies and other stakeholders, where we can discuss how to address concerns as well as incorporate emerging issues and long-term ambitions into PR24.

Cost assessment working group

The role of this group is to engage with stakeholders to help us improve our approach to cost assessment at PR24 and beyond.

We made significant improvements to our cost assessment approach in PR19. We are therefore keen to build on this approach for PR24, taking account of the lessons learnt from PR19. However, we are also keen to hear views on new approaches, including any changes that might take more than one price review period to implement.

Meetings and workshops

Each meeting centres around particular themes / topics, which we announce ahead of the meeting to allow members to identify whether or not to attend, and who they should send.
