Our future plans - PR24 Business Plan and Long-Term Delivery Strategy
Our future plans - business plan 2025 to 2030
Our business plan sets out how we will improve our service to customers between 2025 and 2030.
It will enable us to deliver our purpose - to harness the potential of water to enhance nature and improve lives - which recognises our unique role in society, one where through our day-to-day business we can deliver additional benefits beyond the provision of safe, clean and reliable drinking water.
We submitted our plan in October 2023 and Ofwat made its Draft Determination on the plan in July 2024. We've now provided our response to the Draft Determination and await Ofwat's Final Determination at the end of the year. Please see links below to our response.
