We have published our final determination on the 2024 values of customer reliability methodology. It follows our revised draft determination published on 5 June 2024 and our consideration of stakeholder submissions and feedback. The final determination articulates our reasoning for the decision and responds to key points raised by stakeholders. 

Following this determination, we must update the values of customer reliability using the updated methodology by 18 December 2024. The updated values will be accompanied by a report on the implementation of the methodology.
