Google suggests they do.

However, the Chinese apparently are pretty keen on owning pianos these days. Hmm.)
I think a lot of the acoustic piano decline is "progress", a combination of first everything moving to pre-recorded stuff, and then the introduction of the electronic piano, to be honest. Acoustic pianos used to be a status symbol of the middle class, and before pre-recorded entertainment, there was an entire industry churning out relatively easy salon pieces for amateur piano players to entertain people with (
this piece, not terribly known these days, is an example of an actually massive 1850s "one hit wonder" along these lines). There was less need for salon style entertainment after radio and TV. However, there was no substitute for a piano if you want to learn to play. Nowadays, from what I see, people take lessons using electronic pianos.
Nonetheless, compared to the US, Britain does have a longer, IMHO stronger classical tradition (a few British Baroque composers and a few early to mid 20th century British composers are "classical staples", and there's plenty of lesser known but quality compositions to throw in every now and then). If I had to guess, between all the cathedrals over there and other prominent concert locations (like Royal Albert Hall, which has a big pipe organ) there's more opportunity to make and service pipes. Even from a rock perspective, when I think of bands that have used real pipe organs in tunes, one of the first tunes that comes to mind is British progressive rock
(Yes - "Awaken") It's not that the United States doesn't have pipe organs, we're just different about it. (Fittingly, one of the most notable pipe organs in the US --
the largest active pipe organ in the world in fact -- is in a Macy's in Philadelphia.)
