Where it stands
The inquiry is closed, opened 17 July 2025.
The committee has published 1 report, most recently 4th Report - The new National Policy Statement for nuclear energy generation on 24 October 2025.
The government's response
Published 19 November 2025. The deadline was 24 December 2025.
Summary written by Accountability Index from the government's response. It is not the government's own words.The government welcomes parts of the Committee's report on EN-7, declines several recommendations including changes to section 2.4 and the Semi-Urban Population Density Criterion mapping, and makes a small number of specific commitments.
- On regulatory duplication, it says it does "not share this assessment" of industry evidence, because the NSIP regime must judge project viability. On Recommendation 7 it believes the current section 2.4.5 "strikes the appropriate balance".
- On guidance, it is developing supplementary information for EN-7 and says it "will publish the supplementary information shortly" and update it as lessons are learned.
- On conditional commencement (Grampian conditions), it judges that explicit support in the NPS "is not required", but "can look at this again during future reviews of EN-7".
- On the Semi-Urban Population Density Criterion, it proposes to keep the requirement to consult the HSE rather than publish a map, and says EN-7 "will be reviewed at least every 5 years".
Recommendations and conclusions
- 1: Developer-led low-carbon generation approach lacks assurance without coordinated support and guidance.Conclusion
- 2: Explicitly state preferred nuclear technologies for deployment and envisaged site locations.Recommendation
- 3: Publish a comprehensive plan detailing preferred nuclear technologies, timelines, and GBE-N's facilitating role.Recommendation

Recommendations and conclusions 19 shown
2: Explicitly state preferred nuclear technologies for deployment and envisaged site locations.
Recommended (the committee's words)3: Publish a comprehensive plan detailing preferred nuclear technologies, timelines, and GBE-N's facilitating role.
Recommended (the committee's words)4: Announce GBE-N's specific plans for Oldbury and Wylfa nuclear sites without delay.
Recommended (the committee's words)5: Excessive detail in planning applications undermines regulators and hinders fleet-based nuclear deployment.
Concluded (the committee's words)6: EN-7 fails to provide a joined-up approach across regulatory regimes, delaying progress.
Concluded (the committee's words)7: Strengthen EN-7 to limit Examining Authority information requests to essential planning and environmental impacts.
Recommended (the committee's words)8: Explicitly support the use of conditional commencement mechanisms within EN-7 or its guidance.
Concluded (the committee's words)9: Make clear to DCO applicants the burden of evidence required against each criterion.
Concluded (the committee's words)10: Set out how a "one stop shop" for civil nuclear permitting could operate in practice.
Recommended (the committee's words)11: Government must consider proposals for a diverse fleet of reactors for future energy needs.
Concluded (the committee's words)12: Signal Government's openness to developing technology-specific criteria in the next nuclear NPS.
Concluded (the committee's words)13: EN-7 lacks detailed consideration of the unique socioeconomic impacts of nuclear developments.
Concluded (the committee's words)14: Expand EN-7 on socioeconomic impacts specific to nuclear infrastructure for host communities.
Concluded (the committee's words)15: Investigate creative mechanisms to ensure local economic value from nuclear developments is captured.
Recommended (the committee's words)16: Current SUPDC methodology for excluding nuclear reactors lacks transparency and practical decision-making.
Concluded (the committee's words)17: Publish a map of SUPDC test results for England and Wales, replacing H&SE consultation.
Recommended (the committee's words)18: Commission ONR to develop proposals for a replacement methodology to SUPDC.
Recommended (the committee's words)19: Restate waste heat consideration requirements in technology-specific terms within EN-7 or guidance.
