In June 2025, we published a consultation paper on the proposed creation of a new electricity retail market procedure. The purpose of the new procedure (MPNI 40) is to establish a technical solution that can facilitate a ‘bulk transfer’ of customers from one supplier to another and thereby enable a supplier’s voluntary exit from a specific market sector(s).
This procedure has been proposed as an enduring market solution that could be utilised by any electricity supplier in the future.
Following consideration of the responses to our consultation, the decision paper provides a summary of the responses received and our decision to approve this Market Change Request (MCR 5005).
We received six responses to the consultation, which have been published alongside the decision paper.
