Apologies if this is stating the obvious, so the decision to not use Elstree D is because it's occupied by Strictly or something, rather than general cost cutting?
Has anyone hinted that it's only temporary and they'd like to go back there - how long a lease do Studioworks have?
Strictly used George Lucas Stage 2, George Lucas Stage 1 is still available.
BBC own their own site at Elstree which includes Studio D and the Eastenders production site. BBC Studioworks have announced an extension to their partnership agreement with Elstree Studios which will continue until March 2024, meaning Stages 8 and 9, and George Lucas Stage 2 will continue to be marketed and used by BBC Studioworks.
