Our bills compared to the industry 2025/26

We are doing everything we can to keep our bills affordable for everyone. Whilst there will be some changes to bills this year, this will support important investment of £3.2bn across our regions and will help us to deliver on our customers’ top priorities – continuing to secure safe, clean drinking water, reducing the use of storm overflows and protecting the environment. We offer many support programmes for our customers and this year, we have launched a £200m support package for customers and we are on track to eradicate Water Poverty by 2025 - a commitment we have doubled down on to 2030.

Compared to South West Water’s 2024/25 charges, average customer bills for 2025/26 will increase by a total of 28% (or 41 pence per day). These figures account for updated inflation, current water usage and the current number of customers we serve in our region.
