It says "For all things science fiction, fantasy and horror" under Hodderscape.
I hadn't heard of this imprint before, but their FB page seems to go into early 2014 at least.
Anne Perry is a Hodder editor. On 9-March-2015, she announced that they'll have an open submission period [http://hodderscape.co.uk/open-submissions/] from 3-August-15 through 16-August-15.
Best of luck submitting, folks.
Tangent: The main publisher has been around a long time, but this post is only the second Hodder & Stoughton to make AW (that I can locate). Hodder was the original publisher of The Saint books in the 1900s.
I can't speak about Hodderscape, but as a publishing geek, Hodder & Stoughton has been publishing for a long time. Their sf/f titles were published under the Hodder Headline umbrella when I proofread Locus.
