From the Migration Observatory,

"Net migration to England and Wales averaged 200,000 per year between the 2011 and 2021 Censuses, including British citizens"

That's a town the size of Blackburn and Burnley together being added every year, year on year, to an already overcrowded island. Is it any wonder there is a shortage of houses or that the NHS is under enormous pressure. I would suggest it is simply impossible to build enough houses or hospitals quickly enough to cope with the annual increase in the population.

The last major reservoir constructed was 31 years ago in 1991, the population has increased by around 20% (10 million) since then. They'll be talking about a water shortage soon.
