The UK generates around 15% of its electricity from nuclear power at five operational plants. Government policy targets expansion to up to 24 GW by 2050 through new large reactors, small modular reactors and life extensions, as part of a low-carbon mix with renewables and gas backup to ensure energy security and reduce fossil fuel imports.
What's striking here isn't the margin but its consistency: nuclear expansion carried every single age band, from the youngest voters to pensioners, a rare instance in this chamber of a policy question that didn't fracture generationally at all. Where energy debates usually pit net-zero idealism against cost-conscious caution, here the generations converged on the same answer.
The one divide worth naming is gender: men backed expansion almost to a person, while women, though still solidly in favour, showed markedly more hesitation. That gap tracks a familiar pattern in nuclear polling more broadly, where risk perception and trust in long-term safety cases tend to split along exactly these lines, even as the headline verdict stays lopsided.
The result sits squarely inside the post-2022 energy-security consensus, the turn toward nuclear and renewables driven as much by the shock of gas prices and reliance on imports as by climate targets alone. Support this decisive suggests the "low-carbon plus energy security" framing, rather than a purely climate one, is what now commands assent across the political spectrum.
The floor's arguments mirrored that same tilt toward the long view against near-term caution. The top Yes voice held that "the benefits outweigh the risks a hundredfold" and that progress toward abundant energy "is always a boon", while the leading No voice conceded the case "seems sound" but warned it was "a very large cost for very little gain in the short term."
A chamber this united on nuclear is a reminder that scepticism about the technology, once its defining feature, has become the minority position even among its remaining doubters.
“Nuclear research is marching along at a remarkable pace; the benefits outweigh the risks a hundredfold. Progress towards near-limitless energy is always a boon.”

We should invest in nuclear to allow us to ditch carbon based fuels, this frees up the country to utilise non-carbon fuels while transitioning to completely renewable energy. Nuclear isn't the end goal, but part of a stable transition to having an adequate supply of renewables.
We need a reliable, cheap, independent base load. Wind and solar will never provide it and we should transition away from hydrocarbons. Nuclear is the only answer.
Hinkley c has already cost twice its original budget and is 5 years late. Nuclear waste is not safe and lasts forever. We live on an island surrouned by wind and sea, our investment should be in safe sustainable power. We already have been paying France to take surplus electricity as we generate more than we need at times. We should invest in the national grid to manage our power better, and improve sustainability.
No brainer!
The idea behind nuclear energy and all the information we have about it seems sound. But I think the benefits we would see won’t be a for a while, it’s a very large cost for very little gain in the short term. How much benefit will it provide longer term, who really knows….
With other countries already making inroads into nuclear fusion technology, there is no better time than now for us to join the push into innovating a possibly limitless energy source. It's there, progress is being made, let's seize the opportunity!
The safest and cleanest source of energy. What’s not to like about it.
Nuclear research is marching along at a remarkable pace; the benefits outweigh the risks a hundredfold. Progress towards near-limitless energy is always a boon.
Apart from the waste it produces with a half life of like a billion years.
I don't see how this is a left-right issue at all, it's just common sense and an obviously good idea by all measurable metrics.
