The BBC is such a third-rate broadcaster these days. No pride in anything it does at all, with even BBC News being dismantled beyond recognition. It doesn't surprise me that they can't be bothered replacing something as simple as their own logo on their national HQ.

Bit of an overreaction. 

This is by all accounts a necessary repair to vandalism done a few years back.

Seeing as the BBC logo is comprised of glass panels, I’m guessing it would be harder or more complex to create new panels with the new logo on. I don’t think it’s quite as “simple” as you make it out to be.

Completely agree. Changing this sign will require a planning application and custom made curved glass panels to be produced and installed. This will all come at significant cost which journalists will be waiting to make some noise about so you can see why it's likely to not be particularly high on the BBC's list of priorities. 

This repair today to damage behind will likely have been paid for by an insurer so while it seems a good time to update the sign it won't have been part of the claim.
