2025-2030 electricity default price-quality path
On 20 November 2024, we published our final decisions for the default price quality path for electricity distribution businesses (DPP4), beginning 1 April 2025.
Current step in the process
The process to set the 2025 to 2030 electricity distribution default price-quality path (DPP4) is now complete. The new revenue limits and quality standards are effective from 1 April 2025 until 31 March 2030. You can find all relevant documents from the process in the documents tab at the bottom of this page. These include our final decisions on the DPP4, which were published 20 November 2024.
Open Letter: Ensuring our approach to price-quality paths is delivering for consumers
We have published an open letter seeking stakeholder views on our approach to setting default price-quality paths (DPPs) for electricity distribution businesses (EDBs).
This letter reflects on the recent reset of DPP4, which applies from 1 April 2025, and invites feedback to help shape our future work programme ahead of DPP5, which will apply from 1 April 2030. We have now received 14 submissions. You can find these in the Documents section below.

Workshops
We ran a series of workshops with electricity distribution businesses and other stakeholders as part of the DPP4 process.
