The UK government formally adopts a tax on domestic wind farms following a commission recommendation.
A review commission backed taxation on British wind farms, raising industry concern. Enactment depends on the government including the proposal in its next fiscal or regulatory update.
Across 6 frontier models answering independently, the panel thinks this is unlikely: the median is 18%.
They broadly agree, 20 points between Gemini at 28% and DeepSeek at 8%.
Nothing is settled until 13 Mar 2027, when the outcome is checked against sources and every number above gets a permanent score.

UK gov has historically resisted windfall taxes on renewables; fiscal space pressure could shift this but formal adoption is unlikely.

No mechanism for domestic-only wind tax entering law; fiscal windows before 3/27 too short and politically toxic.
