British Telecom at least says that:
https://business.bt.com/insights/digital-transformation/uk-pstn-switch-off/

  |We're moving all our customers from the old analogue public
  |switched telephone network (PSTN) to a fully digital network. We've
  |already started. We plan to have moved everyone over before
  |Openreach stop the PSTN (and ISDN) service in 2025.

Rather interesting - they still gave offers for ISDN on their website:
https://business.bt.com/products/voice/isdn/

They also seem to switch off the analog lines (PSTN).

In Germany, Deutsche Telekom already switched off ISDN. The old PSTN
network has been replaced with ISDN equipment in the 90s and analog
lines were only available from the switching system to the customer.
They are still, but the backbone is IP-based and new contracts aren't
possible.

I don't know how PSTN is currently handled in the UK.

***** Moderator's Note *****

I'm assuming that "the old PSTN network" means "the old analog central
offices and tandem switches (e.g., Step-by-step or crossbar)," because
I think of ISDN as a "link" protocol that is served via digital
switches and tandems which carry the "Bearer" channels to their
destination in digital form, without any A-to-D or D-to-A
conversions. I think, at least in the U.S., that each Bearer channel
is still assigned to a virtual-circuit switched connection during a
phone call.

If I'm wrong, *please* post a correction!
