PR24 Business Plan Update March 2024

Since submission of our PR24 business plan to Ofwat in October 2023, we have made changes to parts of our plan. These have been in response to requests from Ofwat or other regulators and to clarify some points in our original plan. The result of these changes to date is that Ofwat are now considering a PR24 business plan for Dŵr Cymru that includes total expenditure of £5,627 million (up from £5,101 million in our October 2023 plan), and average annual customer bills of £602 by 2030 (up from £581 in our October 2023 plan). Ofwat's draft determinations will be based on this expenditure and these bills. The reason for the change to our total expenditure for PR24 and associated average annual customer bills is the inclusion of additional environmental expenditure reflecting the latest National Environment Plan (NEP) and updated guidance.
