Our Business Plan 2025–30
This is our largest and most ambitious plan yet, double the size of our current delivery plan at £7.8 billion.
More than 25,000 customers spent over 8,000 hours telling us what they think to help us develop it. They told us they wanted us to continue providing clean, wholesome, safe drinking water now and into the future; reduce leakage; prevent pollutions and flooding and reduce our use of storm overflows while increasing the support we provide to customers in the most vulnerable circumstances.
They were also clear on how we should do things – using new technology and nature-based solutions where we can, collaborating with community partners and showing leadership on key environmental issues.
Here’s a short summary of our plan
