Chancellor Reeves Announces Plan to Shield Clean Energy Projects from Judicial Review, Giving Parliament Direct Power to Designate Critical National Infrastructure
Chancellor Rachel Reeves has announced a package of reforms that would protect nationally significant clean energy projects from judicial review (the legal process by which courts scrutinise whether public authorities have acted lawfully) on all but human rights grounds. Under the proposals, Parliament would be empowered to designate clean energy schemes as being of critical national importance (CNI), providing them with near-complete insulation from legal challenge. The policy note, published on 21 May, distinguishes between the new CNI route — reserved exclusively for clean energy projects given what the government describes as the national urgency of decarbonisation — and a separate fixed legal challenge window for other nationally significant infrastructure including water and transport schemes. Under the fixed-window route, planning consent could be updated to address legitimate issues raised during the challenge period, but the project would not be halted indefinitely. The government's stated aim is to end what it describes as "serial meritless legal challenges" that have imposed billions of pounds in project delays. The reforms complement existing measures including the National Planning Policy Framework, the Planning and Infrastructure Act, and the Fingleton Review (which produced 47 recommendations to accelerate nuclear industry modernisation). Herbert Smith Freehills Kramer partner Catherine Howard described the ability for smaller energy developers to apply directly to the Planning Inspectorate, bypassing local councils, as "greatly to be welcomed".
Why this matters
Restricting judicial review for CNI-designated clean energy projects is a structural shift in UK infrastructure law that directly affects how developers, lenders, and their legal advisers manage project risk. Judicial review risk has historically been a key concern for project finance lenders (banks and investors who lend against the future cashflows of a specific project) when assessing whether to commit capital; removing that risk for CNI projects could materially reduce financing costs and accelerate financial close on major wind, solar, and nuclear schemes. Herbert Smith Freehills Kramer is already publicly engaged on the reforms, suggesting Magic Circle and elite US energy practices are closely tracking the legislative path. The 'why now' is the Iran war-driven fossil fuel price surge, which has elevated the political urgency of domestic clean energy buildout.
On the Ground
A trainee on a clean energy project finance matter would be summarising planning permission and licence conditions against the new CNI designation criteria, coordinating regulatory filing submissions to the Planning Inspectorate, and reviewing grid connection agreements for conditions precedent linked to planning consents.
Interview prep
Soundbite
Removing judicial review risk from CNI energy projects collapses a key financing hurdle — lenders can commit capital earlier.
Question you might get
“If a clean energy project is designated as critical national infrastructure under these reforms, what residual legal challenges could a third-party opponent still bring, and how would you advise a project developer on managing that risk?”
Full answer
The UK government has proposed that Parliament be able to designate clean energy projects as critical national infrastructure, shielding them from judicial review on all but human rights grounds. For energy lawyers, this matters because judicial review risk has historically been a principal concern for project finance lenders assessing whether to fund major infrastructure — its removal should lower risk premiums and accelerate financial close on wind, solar, and nuclear schemes. The change connects to a broader government push, alongside the Planning and Infrastructure Act and the Fingleton Review, to eliminate delays that have cost developers billions. This suggests a sustained pipeline of large clean energy mandates for firms with strong project finance and planning law benches through the remainder of 2026.
