Bold statement: UK physics faces a funding crunch that could shake the country’s position as a global science leader. And this is the part most people miss: the consequences go beyond budgets—they affect talent, infrastructure, and future innovation.
English physics chiefs have published an open letter to science minister Patrick Vallance, voicing “deep concern” about late-2025 funding changes from UK Research and Innovation (UKRI), the umbrella body for the UK’s research councils. The signatories—58 leaders representing 45 universities including Birmingham, Bristol, Cambridge, Durham, Imperial College, Liverpool, Manchester, and Oxford—argue that the cuts create reputational risk and demand strategic clarity and stability so UK physics can thrive.
The letter emphasizes that these funding shifts risk undermining science’s core role in boosting prosperity, health, and quality of life, as well as driving sustainable growth through innovation, productivity, and scientific leadership. The signatories warn that the UK’s international standing in physics is a strategic asset, highlighting particle physics, astronomy, and nuclear physics as especially important.
The timing matters. UKRI announced in December a reworking of how government funding for science and infrastructure is allocated. The Science and Technology Facilities Council (STFC), part of UKRI, said inflation, higher energy costs, and unfavorable foreign exchange movements have raised annual costs by more than £50 million. As a result, STFC expects to reduce its core budget spending by at least 30% from 2024/2025 levels and to cut the number of projects funded by its infrastructure program. Two UK national facilities—the Relativistic Ultrafast Electron Diffraction and Imaging facility and the C-MASS mass spectrometry center—will not be prioritized. Two international particle-physics projects will also lose support: a UK-led upgrade to the LHCb experiment at CERN and an accompanying contribution to the Electron-Ion Collider at Brookhaven.
Oxford’s Philip Burrows, director of the John Adams Institute for Accelerator Science and a signatory, told Physics World that the situation is like “buying a Formula-1 car but not being able to afford the driver.” He notes STFC has been hit hard by flat funding, especially since much of its budget covers international facility subscriptions and operating national facilities. However, most of the remaining budget supports scientists conducting research at those facilities, raising concern that the cuts will hit the scientific program disproportionately.
The letter argues that constraining these areas could weaken the UK’s talent pipeline for the innovation economy. It also stresses that fundamental physics yields substantial public engagement and cultural impact, reinforcing public support for science and the UK’s reputation as a global scientific leader. There is particular worry about the UK’s ability to lead the scientific exploitation of major international projects; a sudden funding pause for key programs could erode the UK’s competitive edge into the 2040s.
The authors call on the government to work with UKRI and STFC to stabilize curiosity-driven physics grants at a minimum level of flat funding in real terms, and to protect postdocs, students, and technicians from the cuts. They also urge a long-term infrastructure strategy and the creation of fair mechanisms to shield the research base from external shocks affecting STFC-funded areas.
Context adds a note of leadership change: Michele Dougherty has stepped down as IOP president and executive chair of STFC, with Paul Howarth stepping in as IOP president. These developments frame a moment of transition as funding debates unfold across UK science policy.
