Exchange closures will be done a exchange by exchange basis. Good Service providers would do that, bad ones not so much
Exchange closures are not happening concurrently with PSTN switch-off though.
There is a plan to close 100 exchanges by 2030, with an initial trial of five exchanges, but that's now dropped down to just three:

Apart from PSTN switch-off there's a whole load of other stuff that needs to happen before an exchange is closed, including getting all the LLU providers out, and all the leased lines which go through it.
