You're mistaken.
Onshore wind in England was de-facto but not de-jure banned by the Tories in 2018, due to a footnote inserted in their National Planning Policy Framework. Labour removed this footnote in 2024, immediately after winning the election. [0]
Offshore wind was never affected, nor onshore wind in Scotland, Wales or Northern Ireland.

Thanks, I was quite mistaken indeed! I wonder how much onshore England then affected the big picture.
Well, Tories would argue that you can't get the really big turbines onshore that you can offshore, so it doesn't really matter. Tiddly little turbines don't generate that much, and why spend lots of money on the planning process and fighting NIMBYs when you can generate it offshore?
However, it does matter, when looked at in whole with the need for capacity in the National Grid. A pile of turbines across SE England would have really helped, because a lot of the offshore wind and Scottish wind power has to be dumped, and gas generators fired up instead, due to lack of grid capacity to distribute that power across the country.
We should, of course, have completed upgrades to the grid by now, but they're late.
