Nine new reservoirs are planned by 2050 apparently. But as general point reservoirs are...

a) only part of the solution (water reuse schemes can be much cheaper and more effective) b) really difficult to build! Finding an appropriate location (google the Tryweryn reservoir in Wales for an example of the consequences of building one in a problematic location), planning constraints, environmental impact and subsequent pushback from locals and environment groups etc etc.

I don't disagree the UK needs more of reservoirs but they ain't trivial things to build. A good overview in this news article here: https://www.bbc.co.uk/news/articles/c2k147dkgx8o
