Chancellor Rachel Reeves is preparing a planning reform package aimed at fast-tracking the UK's most strategically important clean energy and infrastructure schemes by sharply limiting the scope for judicial review.
Under the Treasury's proposal, parliament itself would be able to designate and approve qualifying projects as of 'critical national importance' — a status that, according to the Treasury, would 'reduce the exposure from judicial review on all but human rights grounds'.
Why now
The move is framed as part of a wider response to energy-security pressures linked to the Iran crisis, and to the government's commitment to a virtually zero-carbon power system by 2030.
Renewable developers have spent years flagging the same two bottlenecks: planning permission for offshore wind, onshore solar and battery storage, and grid connection queues. A Cornwall Insight analysis found a record 45GW of new battery, wind and solar capacity was approved across Great Britain last year — almost double 2024 — but build-out has lagged due to long construction timelines and connection delays.
What's being proposed for other infrastructure
For transport and water projects, the Treasury is signalling a fixed legal challenge window. Once that window closes, planning consent could be amended to deal with 'any legitimate issues' rather than reopened to fresh litigation — a meaningful change for promoters of large, capital-heavy schemes.
What it could mean for landlords and developers
If the package lands as briefed, the risk profile of large clean energy schemes — grid-scale solar, onshore wind, BESS, interconnectors — improves materially. Reduced JR exposure typically translates into a lower cost of capital and tighter delivery programmes.
For commercial property owners, the second-order effects matter just as much: faster grid reinforcement, a higher likelihood of nearby renewables coming online, and stronger downward pressure on long-run wholesale prices. That sharpens the business case for on-site PV, BESS and heat-pump retrofits today.
Watch points
The detail will matter. Which projects qualify as 'critical national importance', what role local communities retain in the process, and how the human-rights carve-out is interpreted will all shape how much of the planning risk actually shifts.
Until then, our advice to clients is unchanged: pre-screen sites for eligibility, wind and solar resource, and grid position now, so that you're ready to move quickly when the new regime — or any successor to it — takes effect.
