On this page you can download a summary version of our five-year plan, as well as a detailed public version of our plan.

An independent 'reporter' was appointed to verify that the information we provided to Ofwat was accurate. A public version of their report is also available. 

The information contained within our final business plan reflects our company position at the time we submitted it to Ofwat.

Our position on many of these issues has since moved on, partly as a result of Ofwat's final decision on our proposals, partly due to our progress so far in making the improvements that we agreed with Ofwat, and partly reflecting the changing environment we work in.
