The theremin has grown enormously in popularity in the UK over the past few years, and is home to some excellent thereminists.

 The first exposure of the theremin to the UK was when Leon Theremin gave a lecture-concert as he was en-route to America. This is an area which does require some further research, but he undoubtedly wooed cultured UK audiences with his 'ether-music'.

The first UK thereminist of note was Musaire, though he appears to have been more of an all round vaudeville entertainer than thereminist, though he did play his instrument all over the UK, and in the Royal Albert Hall. 

The theremin is currently championed by Bruce Wooley of the Radio Science Orchestra. The RSO is a collective of musicians, whose line-up changes from concert to concert, and features Bruce Woolley and Lydia Kavina on theremin. Bruce also regularly makes radio and TV appearances to promote the theremin on a local and national basis.

In TV and Film, sadly the UK lacks behind the US, though the 'Midsomer Murders' TV series features the theremin playing of British thereminist Celia Sheen in its theme and incidental music to great effect.
