Delivering for our customers

Our parent company, Pennon, has confirmed plans to deliver what matters most to customers and communities for the period 2025-2030, with record levels of investment across the South West, Bristol, Bournemouth and Sutton and East Surrey. The £3.2bn investment will see further improvements across the main customer priorities – securing safe, clean drinking water, reducing the use of storm overflows across the regions’ bathing waters and protecting the environment, with investments in renewables.

Bills for customers are forecast to increase for water services by £4 per month, and for sewerage services by £5 per month, one of the lowest increases across the Sector. At the same time, the Group is announcing a £200m support package to make sure those customers who need assistance, get the right help, to pay their water bill, as it extends its pledge to end water poverty to 2030.

Susan Davy, Pennon CEO said “Today’s news from Ofwat means that we have been given the green light to invest a record £3.2bn level over the next 5 years. This is on top of the £1.2bn we’ve already invested in our assets recently. We’re serious about making a difference now and in the future - our customers rightly deserve to see real change which we are already delivering. At the same time, we’re here to support customers to use less water, save more money as we do more than ever to support anyone struggling to pay their bill."
