No, Theresa May tried to revive the nuclear programme with Sizewell Hinkley Point C, and was excoriated for it by publications like The Economist (oddly enough, because nuclear power is not price competitive with renewables). Of course, they were assuming the omnipotent and omnibenevolent Market would always provide, including when the sun isn’t shining, and the wind isn’t blowing and the terminals of the power interconnect with France have burned down.
The Tories were certainly sharp-elbowed enough when it came to securing Covid vaccine supplies via beggar-thy-EU-neighbor policies, I don’t know why they didn’t exercise the same supply-chain skepticism towards energy.
That said France went all-in on nuclear in the 70s, but failed to invest in maintaining skills like welding and their socialists (François Hollande) pandered to the greens like in Germany by shutting down replacement nuclear projects and breeder reactor R&D, which is why electricity supply in France this winter is going to be touch and go. But France did invest in insulation, the government paid for 60% of the cost of replacing my parents’ inefficient 40 year old gas furnace with a heat pump last year, and now they are completely weaned off natural gas.
