Unions, thinktanks, environmental groups and charities have jointly urged the government to significantly increase the financial capacity of the National Wealth Fund, arguing that a strengthened institution could unlock lower energy bills, revitalise struggling industrial regions and create more high-quality employment across Britain.
The coalition, which includes the TUC, WWF and the New Economics Foundation, has issued a statement calling for ministers to transform the NWF into a "world-leading national development bank capable of delivering the investment Britain needs". The organisations insist such an overhaul would remain compatible with the government's existing fiscal framework.
The NWF was established by then-chancellor Rachel Reeves with the objective of channelling billions of pounds from the private sector into major infrastructure schemes. It operates on a co-investment model, typically seeking roughly £3 of private capital for every £1 of public money committed to projects spanning ports, gigafactories, hydrogen production and steel manufacturing.
Unlike sovereign wealth funds operated by countries such as Norway and Saudi Arabia—which draw on revenues from state-owned natural resources, trade surpluses, central bank reserves or asset sales—the NWF functions as a catalyst for private investment. It demonstrates government willingness to share the financial risk of large-scale infrastructure ventures, thereby encouraging private capital deployment in the UK.
The push to expand the fund's scope arrives as the Labour party prepares for its first conference since Andy Burnham became prime minister, and ahead of Chancellor John Healey's Budget announcement scheduled for 28 October.
What has the fund achieved so far?
The NWF has already demonstrated measurable impact in its early operations. A Treasury spokesperson confirmed that the fund delivered £3.9bn of investments in its first year across projects including Sizewell C nuclear power station and a second gigafactory in Sunderland, alongside flood defence improvements in Wales. These investments generated an additional £5.25bn in private finance and secured or created 11,500 jobs.
More recently, the National Wealth Fund announced that it has now committed £10bn across infrastructure, places, businesses and technologies. On 11 September 2026, the fund provided a £38.4m loan to Edinburgh's Granton Waterfront project, and expanded its regional partnerships programme to South Yorkshire, Liverpool City Region, the North East and Cardiff Capital Region on 7 September 2026.
The Treasury spokesperson stated: "The government remains committed to the NWF's long-term mission to crowd in private capital and drive economic growth into every postcode in the country."
How much more could the fund invest?
The coalition's statement highlights a significant disparity between the NWF's current capacity and that of comparable institutions abroad. The fund has £5.5bn available annually for the next five years, yet Germany's public investment bank KfW lent €62bn (£53.5bn) to households, businesses and municipalities in 2025 alone—nearly 10 times higher.
According to the National Wealth Fund's strategic plan, the institution is capitalised with £27.8bn, has deployed £8.4bn to date, and will commit the remaining £19.4bn by 2030/31. The fund's January 2026 strategy document projected it could drive more than £100bn into the UK economy by 2030/31.
The organisations calling for expansion argue that the Resolution Foundation has calculated that rule changes to the fund could allow an additional £9bn of annual investment by 2031 in real terms.
What specific benefits could expansion deliver?
The coalition has outlined several concrete ways a scaled-up NWF could benefit the British economy. These include accelerating the retrofitting of homes and buildings to improve energy efficiency; enabling the public to acquire part-ownership stakes in critical infrastructure projects; launching targeted investment programmes to attract new green industries to communities most severely affected by deindustrialisation; and establishing a network of regional banks to channel capital into small businesses that underpin local economies.
The group praised the NWF's "important role" in "steering private investment to support clean energy, modern infrastructure and regional growth", citing its £500m partnership with the Manchester Good Growth Fund as an example of effective regional deployment.
What changes would be needed?
To achieve this expanded remit, the coalition argues that the government must grant the NWF independence to raise its own finances and invest over extended timeframes—a model adopted by successful public banks worldwide. The organisations contend this approach would remain consistent with the government's fiscal rules, which require day-to-day spending to be matched by income and restrict borrowing to investment purposes.
The statement emphasises that such reforms would combine "fiscal credibility with economic ambition, delivering visible investment" across the country.
Prime Minister Burnham has previously indicated he would examine "any flexibility" within the government's existing fiscal rules to enable substantially increased borrowing for infrastructure investment. This signals potential openness to the coalition's proposals, though no formal commitment has been made.
What happens next?
The NWF's framework document specifies that the fund should be reviewed regularly and updated at least every three years, with the next scheduled review set for April 2029. The fund intends to commit its remaining £19.4bn by the end of 2030/31, according to its strategic plan.
The coalition's statement arrives at a critical juncture for economic policy, as Chancellor Healey prepares to outline the government's fiscal and investment strategy in his October Budget. The timing suggests that calls for NWF expansion may feature prominently in broader discussions about how to fund the infrastructure and regional development initiatives the government has prioritised.
