Bit strange - the current set isn't that old, and there are many regions who had a studio refit before Midlands Today got their current set, and so probably need it more!
Yes, BBC Look East (Norwich) comes to mind.
Are refits the decision of each region in how they spend their budget with larger fullscale technical refits subject to higher approval for the additional budget required?
Yes to an extent. Technical refits are funded by a different pot of money to set refreshes/changes and there's a strategy being developed for long term technical equipment overhauls in the regions. A lot of regional centres have kit that's getting a bit long in the tooth now and there are many different bits of kit across the centres being used (in areas like graphics and caption generation particularly). Around the turn of the millennium and coincidentally when The Mailbox and The Forum were being moved in to, there was a template for English regional centres, known as Project England. That template specified Quantel editing (and playout initially, though this was replaced with ServerPlay), Aston green or higher + BigTed control, GVG Zodiak vision mixer and so on. It set out the principle of having a "media hub" for ingest and lines recording/playout, newsroom based server viewing seats based on qCut, newsroom based basic edit seats using qEdit and 'craft' edit suites using qEdit Plus. Lots of these ideas were brand new in English regions, who had been tape based up to then, with traditional Multi Format dubbing areas, tape based TX suites, and 2- and 3-machine vt edit suites.
As time's gone on, some of the kit that was purchased back then remains in use but is getting pretty old. While quantel editing is still a fully supported system (and one they still sell I think) more recently refurbished centres couldn't get the exact kit as specified by the template, so procured newer vision mixers, different graphics solutions etc, so there is once again an increasingly disparate selection of technology across English regions.
Back to sets, when I've been involved in new set design and installation, that's all been paid for by the region in question. There are ways of saving money and still achieving a look that's connected to network style sets :- Jersey used a local shopfitting provider in their current set. Oxford used a local industrial flooring specialist to replace the wooden laminate with a decent vinyl floor. I've known bits of set turn up years later elsewhere having been stored in a scene dock somewhere and someone simply spotting it and asking if they can have it. You'd be staggered how much a bespoke desk design and build can cost, especially if it incorporates electrics, lighting etc.
