This article says the palace is undergoing a half a billion pound renovation. From what I have seen, Charles and Camilla have continued to live at Clarence House on the mall and will likely be there for another 5 years.

Had a look at a couple of webcams but its dark now in London so difficult to see whats actually going on.

I'm a brit but I live in Greece so I'm out of touch with the goings on in the UK. However, while searching for an answer, I came across the following web page. It seems to be a jumble of random sentences designed to attract clicks. I've seen some interesting "Search Engine Optimisation" but this takes some beating!

Buck Palace is a publicly owned palace so the taxpayer has to pay for this. Sandringham and Balmoral are the only ones wholly owned by the crown, even Windsor Castle isn't theirs.

What happened to event that was supposed to happen after the Queen passed??? That's when I stopped believing everything.
