Emma Ayech, Luke Hales, Gerald Casey, Adam Collings and Vicky Walker all get promotions in the rejig, effective immediately.
However, the changes also place question marks over director of programme acquisitions Catherine Mackin, and buyer and copros lead Alexandra Finlay. Commercial partnerships chief Sally Quick has left.
Significantly for the international market, Emma Sparks has been named head of acquisitions, meaning she is in charge of relationships with US studios, UK superindies and co-parent BBC Worldwide.
Meredith Coral is new head of coproduction, having been promoted from head of business development and programme distribution.
She will focus on international copros, and deals with distributors and programme makers, with a major focus on drama.
Current head of acquisitions and coproductions Finlay and Mackin are understood to remain with UKTV, though their futures are unclear.
Acquisitions are, in effect, being integrated within channels teams, with execs reporting into Adrian Wills.
Coproductions will fall under the oversight of UKTV chief commercial officer Simon Michaelides, who is leading a new programme funding unit.
The new channel chiefs will report into UKTV controller Emma Tennant, Wills and Steve North, who will now work alongside recently appointed UKTV Play general manager Richard Williams.
Wills and North take on new posts as genre GMs for drama and lifestyle, and comedy and entertainment respectively, reporting into Tennant. Effectively, they have strategic control of the thematic channels group.
Former Really, Home, Good Food and Eden GM Ayech is now in charge of Drama and Alibi, while Hales, who is currently overseeing Ayech’s previous networks as interim GM, become channel director of Dave.
Dave programming manager Casey becomes channel chief of Gold and Yesterday, and W’s head of programming Collings is upped to channel director, adding Really to his duties too.
Elsewhere, Drama programming manager Walker is named channels boss at Home, Good Food and Eden.
Commissioning chiefs Richard Watsham and Hilary Rosen and their team will be unaffected by the changes.
A UK spokesperson said the moves were reflective of growth within the BBC Worldwide- and Scripps Networks Interactive-owned multichannel business.
Headcount will not be affected by the changes, which have been made in order to push further into VOD, international coproduction and other new business models.
It is UKTV’s largest restructure since June 2014, when North and Wills were handed expanded remits, with Clare Laycock exiting for Discovery Networks UK and Ireland and Steve Hornsey also leaving.
