Business Customer Measure of Experience (B-MeX) working group

The B-MeX working group has been set up on behalf of the Market Performance Committee (MPC) to develop a Pilot B-MeX Survey. The group will be responsible for investigating and creating a pilot solution to capture the business customer experience with a wholesaler, following the publication of the Europe Economics report. Learnings and feedback from the Pilot will then be used to develop a B-MeX solution for the Market.
