Designing and running the BR-MeX pilot year

The overarching objective of BR-MeX is to incentivise wholesale water companies to provide an excellent wholesaler customer experience to business customers and Retailers. Ofwat and MOSL are working collaboratively on commissioning a design and research project to develop and pilot the two primary surveys that will measure performance in this area, namely these are: 1. B-MeX: A survey aiming to seek business customers' feedback on wholesaler performance through a survey based on a specific customer contact with the wholesaler. 2. R-MeX: A survey to seek Retailers' feedback on wholesaler performance. The primary objective of this project is to design, test and pilot all aspects of the B-MeX and R-MeX surveys in 2023-2024 to ensure the survey methodology is robust for a full-scale shadow run in spring 2024.
