what's left at the local Studies

Central's playout moved to Leeds in 2002, I'm sure of it.
However Birmingham was the network back-up and for a while remained home to CITV until last year when it disappeared off to Manchester.
Its still going in Birmingham, though what role it plays now outside of Central News I can't be sure.

ironically some bbc birmingham programmes are edited at central court

Signpost BSL is still at Tyne Tees, isn't it? One of the few big public service facilites that remain from when TTTV were an independent company.

ISTR that some of the ITV Local website maintenance work has been moved up to Gateshead as well.

I believe so, Leeds became the "Northern Transmission" for ITV if I recall. I believe the ITV Duty Office is still at Gas Street though?

does have anything else bar a newsroom and duty enquire office

there used to be an Anglia tv office in Northampton, no idea what was in there though

I think they're moving it to a small new-town near Southampton called "Irony".

Anglia certainly had a number of regional bureaux with a journalist nominally based in each one. They had inject points back to Norwich, to allow material to be fed. Think initially this was track and rushes in the days Anglia used MII but they may have got laptop DV editors when they switched to a DV format (DVCPro or DVCam - can't remember) Think they had the facilities to do lives from the injects - but can't remember if they had a small studio with a basic backdrop and camera for this or used a crew.

They had a small studio and bureau in Cambridge City Centre for a while in the early 90s - but this closed - and I think the operation was relocated further out (in a larger space)

Really? I'm surprised they didn't follow HTV's lead and outsource their playout to Mumbai.

As others have mentioned - Meridian have a main newsroom and three studios for the three subregions all based in a tin-shed at Whiteley. Northam has shut, as has the old Meridian studio and newsroom at New Hythe.

Ironically the Meridian SouthEast Newsroom has moved back to occupy the space at Vintners Park in Maidstone that TVS News used to use as the newsroom for the South East edition of Coast To Coast (though with no major studio or production effort based there)

Not sure whether they've relocated in Newbury, and now that Central South is merged into this region, what has happened to Abingdon.

So does Carlisle have anything bar there newsroom?

AIUI the ITV plc playout operations are now confined to Leeds and London, though UTV, SMG and Channel have their own operations in addition to these (not being part of ITV plc)

The major studio centres are Leeds (YTV), Manchester (Granada) and London (LWT / The London Studios) - these are where most ITV networked shows are made.

Most other ITV plc centres only operate studio for their local programme production commitments - either they've relocated to smaller premises suitable for just news programme production (Meridian, Tyne Tees), mothballed facilities, or in the case of split-centre operations, sold off some of their facilities and consolidated in one operation (Anglia). In some cases they didn't have anything more than they needed anyway (WestCountry) - as when they were awarded their franchise it didn't require a commitment to studio production for the network.

HTV West and HTV Wales are more interesting, as are the non-ITV plc companies.
