In the town where I live there are a lot of summer homes that are unoccupied in winter. In London, there are obviously a lot of homes that the rich use when they are visiting. This is an extravagance that is affecting the UK as a whole and a second home tax might help a little. I don't think that the above measures go anywhere near far enough though.
