While writing this post, the movie has not yet been released. However, some locations are released by Birminghammail.

Including: Cornwall Street and Chamberlain Square.
Cornwall street will feature a “carchase with gunfire”.
Also Camberley in Surrey (UK) was used, here Poppy’s Bowling Lane can be found.

Studio work was done at Warner Bros, Leavesden.

Seems this movie is not set in London like the first Kingsman, although some filming took place here in December 2016 (after principal photography wraped).
