It's entirely possible in the UK, it's just simply not very popular anymore as the region has already seen a major push back against overbearing Christian practices and pushed most of them out to the Americas and elsewhere.
Today there are on the order of a 100 or so committed Satanists in the UK according to:
Journal of Contemporary Religion: Satanism in Britain today (1995) - Graham Harvey
This paper discusses the views and activities of self‐identified Satanists in Britain, especially the Temple of Set, the Church of Satan, the Order of the Nine Angles and Dark Lily. It also comments on ad hoc, adolescent and multi‐generational Satanism.
Satanism is a series of techniques for allowing individuals to affirm, develop and express themselves, and to do what they wish to do in the context of a spirituality.
It does not require belief in the Satan of the Christian pantheon although thriving on the sinister image and the hostility it can evoke in Christians and the media.
Satanism is an adversarial form of self‐religion.
...
There are Satanists in Britain.
There are six groups who between them have less than 100 members.
There are more people who read Satanist magazines or have bought books by Satanists, e.g. Anton LaVey's
Satanic Bible (1969).
Again they are few in number compared to the scare-estimate.
A larger number of people—some adolescents—name themselves Satanists, but belong to no formal or organised Satanist group.
