In a trading update, the utility - which supplies around 4.6m homes and business in the Midlands and Wales - said it had seen a "strong start" to the current five-year regulatory period, which runs until 31 March 2030.

The Coventry-based firm invested around £360m in its capital programme during the first quarter, up 19% year-on-year, while the average sewage spills performance was around five in the first six months of 2025, down 65% on the same period in 2024.
The blue chip is due to publish interim numbers in November. Earlier this week it warned customers that a hose pipe ban remained an option, after a dry spring and hot June meant there was less water than normal in its reservoirs and in rivers.
