UK water companies have been granted a modest increase in revenue following a decision by the Competition and Markets Authority (CMA). Bloomberg posted on X that the CMA largely upheld the restrictions imposed by the industry regulator. This decision comes after water companies appealed against the regulator's limits, seeking higher revenue allowances. The regulator's original decision aimed to balance consumer protection with the need for infrastructure investment. The CMA's ruling is seen as a compromise, allowing some increase in revenue while maintaining regulatory oversight. The outcome is expected to have implications for future regulatory decisions in the sector.
