Calls Grow to Expand UK National Wealth Fund

Published: 21 September 2026. The English Chronicle Desk. The English Chronicle Online.

Unions, thinktanks, environmental organisations and charities are calling on the UK government to significantly strengthen the financial capacity of the National Wealth Fund, arguing that a larger public investment institution could help unlock private capital, support industry and reshape the country’s economic prospects.

The coalition wants ministers to transform the National Wealth Fund into what it describes as a world-leading national development bank capable of providing greater long-term investment for Britain. The proposal comes as the government prepares for a new political and economic phase, with Labour’s annual conference approaching and Chancellor John Healey preparing his first budget, scheduled for 28 October.

Supporters of the expansion argue that the fund could play a greater role in addressing some of Britain’s most persistent economic challenges, including regional inequality, industrial decline, high energy costs and shortages of investment in infrastructure.

The organisations behind the campaign include the Trades Union Congress, environmental groups and economic thinktanks. They say a larger and more independent National Wealth Fund could support investment in clean energy, modern infrastructure, housing improvements and new industries while helping attract additional private-sector finance.

The National Wealth Fund was launched in July 2024 by the then chancellor Rachel Reeves. Its original purpose was to use public money to attract significantly larger amounts of private investment into major infrastructure and industrial projects.

The model was based broadly on attracting about £3 of private investment for every £1 of taxpayer funding. Projects identified for support have included ports, gigafactories, hydrogen production, steel and other strategic industries.

The institution differs from sovereign wealth funds operated by countries such as Norway and Saudi Arabia. Sovereign wealth funds generally manage substantial pools of government-owned assets or revenues, often generated through natural resources, trade surpluses, reserves or privatisation. The National Wealth Fund instead operates primarily as an investment institution intended to reduce risk for private investors and encourage them to commit capital to projects in Britain.

The latest campaign seeks to expand that role.

The organisations involved say the fund currently has substantially less financial capacity than some comparable public investment institutions elsewhere in Europe. They point in particular to Germany’s KfW, a major public development bank that lent €62bn to households, businesses and municipalities during 2025.

By comparison, the National Wealth Fund has access to about £5.5bn a year for investment over the next five years. Campaigners argue that the difference demonstrates the scale of the financial capacity that could potentially be mobilised through a larger British public investment institution.

Their proposal would give the National Wealth Fund greater independence to raise finance and make long-term investments. Supporters say such an arrangement could allow the institution to operate with a longer time horizon than conventional government spending programmes.

The argument is also linked to the government’s fiscal rules. Campaigners say an expanded fund could operate within those rules because borrowing for productive investment is treated differently from borrowing to fund day-to-day spending.

They argue that greater investment capacity could therefore combine what they describe as fiscal discipline with a more ambitious approach to economic development.

One area identified by campaigners is the improvement of Britain’s housing stock. A large-scale programme to retrofit homes and other buildings could reduce energy consumption and potentially lower household energy bills while supporting employment in construction and related industries.

The coalition also wants the public sector to take greater ownership stakes in strategically important infrastructure. Instead of simply providing financial support to private projects, a stronger National Wealth Fund could potentially acquire part ownership in critical assets, allowing taxpayers to share in future returns.

Another proposal involves directing investment towards communities that have experienced decades of industrial decline. Campaigners argue that targeted investment could encourage the development of green industries in areas that were particularly affected by deindustrialisation.

Regional finance is another part of the proposal. Supporters say a network of regional banks could help direct capital towards smaller companies that are important to local economies but may struggle to secure sufficient funding through conventional financial institutions.

The campaign comes at a significant moment for the government. Prime Minister Andy Burnham has previously indicated that ministers would examine the flexibility available under the existing fiscal framework in order to support additional infrastructure investment.

The question of how much the government can borrow while maintaining confidence in the public finances is expected to be central to the economic debate ahead of the autumn budget.

An expanded National Wealth Fund would therefore represent not only an investment policy but also a wider question about the role of government in Britain’s economy.

Supporters argue that private markets alone may not provide enough capital for projects involving long construction periods, substantial upfront costs or uncertain returns. Public investment institutions can potentially reduce some of those risks and encourage private investors to participate.

Critics of greater state involvement could instead question the financial risks involved and the possibility that taxpayers could ultimately bear losses if investments fail. The effectiveness of such a model would depend heavily on how projects were selected, how risks were managed and how independent investment decisions remained from short-term political considerations.

The government has pointed to the National Wealth Fund’s performance since its creation as evidence that the institution is already delivering on its original purpose.

A Treasury spokesperson said the fund had delivered £3.9bn in investments during its first year. Projects cited included Sizewell C, a second gigafactory in Sunderland and flood-defence improvements in Wales.

The Treasury also said the fund had helped generate an additional £5.25bn in private finance and had secured or created around 11,500 jobs.

The government remains committed to the fund’s long-term mission of attracting private capital and supporting economic growth across the country, according to the Treasury.

Those figures form an important part of the debate over whether the institution needs a fundamental overhaul or whether its existing structure should simply be expanded gradually.

For campaigners, however, the scale of Britain’s economic challenges requires a much more substantial intervention. They believe the National Wealth Fund could become a central institution for financing the transition towards cleaner energy, modern infrastructure and new industrial capacity.

The timing of the proposal also reflects broader concerns about Britain’s economic model. Regional inequalities remain a major political issue, while businesses and households continue to face questions about energy costs, infrastructure and long-term investment.

A stronger public investment institution could, in theory, provide a mechanism for linking these issues together by directing capital towards projects with both economic and social objectives.

Whether ministers adopt the proposals will depend on the government’s assessment of fiscal constraints, investment risks and the potential economic returns. The forthcoming budget is expected to provide a clearer indication of how much additional emphasis the government intends to place on infrastructure and long-term investment.

The debate over the National Wealth Fund therefore extends beyond the size of a single institution. It raises broader questions about how Britain finances major projects, how much risk the state should share with private investors and how public money can be used to encourage economic development.

As the government prepares for its next major fiscal decisions, campaigners are seeking a larger role for the fund, while ministers are emphasising the investments and private finance already generated through its existing model. The outcome could shape the future direction of public investment in Britain and determine how much financial capacity the National Wealth Fund has to influence the country’s economic transformation.
