There is only one type of cicada in the United Kingdom, and it is called the New Forest cicada (Cicadetta montana). It is named for the New Forest National Park, where these cicadas can be found in the pasture woodlands. It is both rare and endangered, according to this FAQ, however, according to another website, it might be extinct. It sounds like a small gas motor (in my opinion).
Cicadas belonging to the Genus Cicadetta are known as “small grass cicadas”. The New Forest cicada belongs to the same subfamily (Subfamily Cicadettinae) as the Magicicada periodical cicadas that live in the U.S.A.
