This was what HMT call an 'RDEL' event (bit.ly/2SCYdjH). In other words, a review of government's resource spend. It isn't intended to move major capital programmes (that's for next year). It's also only a one-year review.
A cynic might say that achieving these shifts before an election is also unlikely.
The extra £30m for BEIS, which is receiving lots of negative attention, is 'admin' (ie staff) and programme expenditure. That's a potentially huge increase in staffing on #netzero. That's good.
That said, climate change doesn't hang around for 'CDEL' events...
