Both the “E” and “C” gates have the necessary facilities available.
I’ve done SK925/926 a few times, and it’s even chance it’ll arrive at an “E” gate. On the other hand, it’s always been on time or a bit early.
55 minutes would probably be a bit too tight for my taste, but there are plenty of departures with BA and SK to Heathrow during the day if you miss your connection.
No. There is no immigration from E to C gate (or vice versa) in the non-Schengen area. I have done this 7 times in the last two years (US to DUB/LHR and vice versa via CPH). It does not matter where you arrive at C or E, you are transiting.
You only go through immigration if you
enter Denmark.
