Detail
We introduced the developer services measure of experience (D-MeX) during the 2019 price review (PR19). A common performance commitment which applies to the 17 largest water companies in England and Wales, D-MeX is designed to incentivise companies to improve the service they provide to developer services customers, including property developers, self-lay providers and new appointees (NAVs). This document presents our assessment and decisions following our 11 February 2021 consultation on changing the Water UK metrics in D-MeX.
