R-MeX finds Bristol, Portsmouth and Wessex serve retailers best

Retailers rated Bristol Water as the best performing wholesaler in the first ever R-MeX survey. Bristol secured an overall service score of 8.5 out of 10 and scored very highly across all seven individual service areas. It was closely followed by Portsmouth Water and Wessex Water, both of which chalked up an overall service score of 8 out of 10.

At the bottom of the table were Thames Water (6.1), South Staffs and Severn Trent (6.3 each).

The R-MeX consists of 10 questions covering topics such as engagement, communication and data quality. Retailers are asked to provide a score between 0-10 with the option to provide additional feedback via an open text field.

14 retailers, representing 87% of the supply points and 85.7% of the water consumption in the market took part. For future surveys, MOSL is keen to hear from the 13 retailers that chose not to take part, and to work with those who only rated some of the wholesalers they work with. It is also keen to work with wholesalers to understand how, and where, they are planning to use the feedback to make improvements.
