September 2026
Frustration has been mounting over the UK’s continued failure to deliver major infrastructure projects efficiently, on time, and within budget.
Last month that came to a head with the publication of the damning Stewart Review of the much-delayed and significantly over-budget HS2 project, designed to generate huge economic benefits by linking the North of England to London and the South via high-speed rail.
The long-delayed and vastly over-budget HS2 scheme has now sparked a broader government rethink on how large-scale infrastructure, transport, and clean energy projects are planned and delivered across the UK.
New 10-year infrastructure strategy drives UK investment
In response to systemic inefficiencies, the Government unveiled both a reset plan for HS2 and a new 10-Year Infrastructure Strategy aimed at bringing stability, investment, and long-term renewal to the UK’s infrastructure pipeline.
Decision-making on major capital projects will now be guided by the National Infrastructure and Service Transformation Authority (NISTA) – formed in April via the merger of two former advisory bodies.
Clean energy investment and Net Zero: A strategic priority
A significant portion of the 100-page strategy is devoted to positioning the UK as a “clean energy superpower.” The Government reiterates its commitment to:
- Accelerating renewable energy generation (including solar, onshore and offshore wind)
- Scaling battery storage and energy flexibility
- Investing in nuclear power as part of a diversified low-carbon mix
- Decarbonising key sectors: industry, heat, transport, buildings and public services
Although many of these goals are not new, the plan’s emphasis on strategic clarity and coordination marks a shift in tone.
Unlocking renewable energy growth through spatial planning reform
One of the most significant changes is the proposal to remove planning barriers by introducing a new “spatial approach” to infrastructure development. This would integrate planning across sectors and regions – aligning energy, housing, and transport priorities to ensure both national and local needs are met.
This approach will be led by the National Energy System Operator (NESO) and supported by a new spatial digital tool from NISTA. The tool is designed to map infrastructure requirements and inform planning decisions with a data-driven, joined-up method.
However, questions remain around how this could affect public consultation rights and local objections, which have traditionally slowed down large-scale development.
What this means for investors and the energy sector
From a legal and investment perspective, this shift signals a more coordinated policy environment for those engaged in renewables, infrastructure funding, and energy transition projects.
For developers, utilities, and clean energy investors, the changes could reduce red tape, improve grid connectivity, and provide greater certainty over infrastructure siting. For lawyers and advisers, it creates a growing demand for strategic support on regulatory navigation, planning risk, and project finance.
Can strategy deliver confidence?
Major infrastructure projects are inherently complex, politically sensitive, and vulnerable to delays, overspend, and mismanagement. The Government’s 10-Year Infrastructure Strategy is an ambitious attempt to restore leadership, investor confidence, and operational discipline.
If effectively delivered, it could redefine how the UK builds its future – across energy, transport, and beyond.
