Five water companies have challenged a regulatory decision by Ofwat, potentially leading to higher-than-agreed bill increases for millions of households. The firms argue the current cap prevents them from meeting regulatory requirements. According to reports, thousands of households will see their water bills rise by more than previously agreed after five companies complained to the competitions watchdog.
The companies – Anglian Water, Northumbrian Water, South East Water, Southern Water, and Wessex Water – argued that Ofwat's decision meant they would be unable to meet regulatory requirements. These five companies collectively serve approximately 14 million people. Ofwat had previously allowed 16 water companies to increase bills by an average of £157 over a five-year period, between 2025 to 2030.
It remains unclear what specific regulatory requirements the five companies claim they cannot meet with the previously agreed bill increases. The exact amount of additional bill increases for households as a result of the complaint is also unknown. The current status or outcome of the complaint made by the five water companies to the competitions watchdog has not been confirmed.
How the bill increases will affect different regions or customer groups served by the five companies is still uncertain.
