Chancellor Rachel Reeves unveiled a £40 billion infrastructure and green energy spending package on Wednesday in her Spring Spending Review, the most ambitious public investment programme since the post-war reconstruction era. The package, spread over five years to 2031, allocates funds across rail modernisation, clean energy grid upgrades, gigafactory investment in the Midlands and North, and a new National Wealth Fund designed to crowd in private capital for large-scale infrastructure projects.
The centrepiece of the announcement was a commitment of £12 billion to accelerate the rollout of offshore wind capacity, bringing forward the government’s target of 50 gigawatts of offshore wind by 2030. The funding will support grid connection infrastructure, port upgrades in Hull, Teesside and the Humber, and supply chain investment intended to ensure that a larger proportion of components for UK wind farms are manufactured domestically.
Rail investment received £9 billion, with the largest single allocation going to the electrification of the TransPennine route between Manchester and Leeds — a project that has been repeatedly delayed and re-scoped over the past decade. The Chancellor described the investment as “essential to rebalancing the UK economy and delivering on our promise to the North.” Additional funding was earmarked for urban transit systems in Birmingham, Bristol and Glasgow.
The National Wealth Fund, which will be capitalised with £8 billion of public money, is designed to operate as a co-investor alongside pension funds, insurance companies and sovereign wealth funds in projects that the private sector judges too risky to finance alone. The model is loosely based on the German KfW development bank and Canada’s infrastructure investment model, both of which have been credited with mobilising substantial private capital for public benefit projects.
Business groups broadly welcomed the package, with the CBI describing it as “a serious down payment on the productive capacity the UK economy urgently needs.” However, the Institute for Fiscal Studies cautioned that the spending plans assumed optimistic growth projections and that any shortfall in tax revenues could force difficult choices in future fiscal events. The Office for Budget Responsibility will publish its assessment of the spending review alongside updated economic forecasts next week.
Opposition politicians focused their criticism on the government’s debt financing plans, with Shadow Chancellor Mel Stride arguing that borrowing to fund infrastructure investment risked undermining the credibility of the UK’s fiscal framework and pushing up gilt yields at a time when debt servicing costs were already elevated.
