Response to Ofwat’s Final Determination

Ofwat’s publication sets out how much water companies can invest in their networks over the next five years – and how they should set customer bills to support that activity

Our teams are now reviewing Ofwat's decision carefully to make sure it meets the needs of our communities and environment.

Responding to the Final Determination for Southern Water, our CEO Lawrence Gosden said:  

“We note Ofwat’s publication of its Final Determination for 2025-2030. It’s important that we take time now to review all the detail carefully, as we seek to understand the level of support the regulator has shown for our ambitious investment plan.  

“We’re very conscious that a rise in bills isn’t easy for our customers, essential though it is to delivering the improved performance and infrastructure that’s required. So we’re significantly expanding the wide range of support available for those customers who are most in need. 

“Our plan was driven by the views of thousands of Southern Water customers. That’s why we need to be sure that what’s been set out in Ofwat’s Final Determination meets the expectations of our communities -- in protecting the environment and building a truly resilient network for future generations. 

“We’ll say more about Ofwat’s Final Determination in due course.”
