Failure to go further, faster over the next five years on plans for infrastructure delivery could constrain economic growth and threaten climate targets, according to the government’s official infrastructure advisers.

Noting the UK has faced several years of disruption from Covid and the cost-of-living crisis, the National Infrastructure Commission’s annual review charts a mixed picture of progress towards key infrastructure goals:

• Five-year funding settlements for local transport have been devolved to more city regions
• Funding diverted from the cancelled northern leg of HS2 has been earmarked for local transport budgets, but without a detailed replacement plan for improving train services in the North and Midlands the decision risks future capacity challenges
• The share of electricity generated from renewable sources has grown to a record 47 per cent in 2023 and there have been welcome moves to accelerate the rollout of transmission infrastructure to get electricity where it is needed, but changes to the planning system for onshore wind developments are not sufficient for this source to meet its potential
• Last minute changes to policy have created uncertainty and reduced the incentives to install a heat pump, which risks slowing the transition from fossil fuel heating. Government is currently off track to meet its target of 600,000 heat pump installations by 2028
• Demand for water has plateaued rather than fallen, compounding risks to future supply, while network leaks are not being fixed at the rates required to meet the industry’s own targets, with weather conditions leading to a rise in leakage levels for most companies during 2022/23
• Updated National Policy Statements for energy, national networks and water resources should ensure faster decision making on major projects, but opportunities remain to go further by expanding community benefits for hosting infrastructure and reducing duplicative environmental assessments.

The Commission’s Infrastructure Progress Review 2024 calls for a concerted catch up programme accelerating policy implementation and delivery to ensure the country’s infrastructure is fit for the future.

In its recent National Infrastructure Assessment, the Commission calculated that public investment in infrastructure will need to reach around £30 bn a year over the coming decades (from around £20 bn a year in the past decade), alongside an uplift in private investment to around £50 bn a year.

Writing in the report’s foreword, Commission Chair Sir John Armitt bills the next five years as a “a critical period for making decisions on things that are of immediate concern to the public – the three Ps of prices, potholes and pollution”.

Addressing these areas, the report calls for:

• Coherent policy backed by long term public funding to boost the transition to low carbon home heating that should help to reduce household bills over the longer-term
• Continued progress on devolution, expanding its reach to give all local authorities with responsibility for local transport five-year funding settlements to enable more stable planning for road maintenance and other priorities
• Transformational change in the water sector, that will require some bill increases, to address interconnected sewage and drainage problems.

The report also includes new analysis on the railway network in the North and Midlands in light of the decision last autumn to cancel work on High Speed 2 north of Birmingham.

Offering an initial assessment of how current plans will impact connectivity and capacity, the Commission notes “government’s plans might address a number of issues, but greater specificity is needed regarding the scope, cost, benefits and schedule for the schemes individually and as a package”.

The Commission believes “existing infrastructure is a constraint on future passenger and freight growth. Capacity and connectivity cannot be materially improved north of Birmingham without further infrastructure investment.”

To enable passenger growth in the future, the report says, “a ‘do nothing’ scenario north of the proposed [Handsacre junction] is not sustainable”, while also nothing that major improvements to both inter-urban transport and local transport networks are affordable within indicative spending limits set for the Commission by government.

Sir John concludes:

“A window remains to ensure that practical delivery plans are in place, backed up by the necessary public and private funding, to help achieve economic and environmental goals that will improve life for British households. But the window is closing, at least if we don’t want to delay those benefits and compound the disruption of recent years.”
