STFC budget 2026 settlement holds cash funding flat for the Science and Technology Facilities Council across the spending review period to 2029–30 — but rising inflation, energy, and international-subscription costs mean STFC must still find £162 million in savings, with facilities and external grants each absorbing roughly £38 million in cuts.
The Science and Technology Facilities Council (STFC) is one of UK Research and Innovation’s nine constituent councils, responsible for funding and operating national scientific facilities and research grants in particle physics, astronomy, nuclear physics, and related fields.

What is the STFC 2026 budget settlement?
The STFC 2026 settlement leaves cash funding for the council essentially unchanged across the current four-year spending review period, which runs to 2029–30. Hansard’s record of the House of Commons debate on 18 March 2026 confirms that “the STFC’s budget is actually flat over the spending review,” while noting overspends against that budget in preceding years.
A flat cash settlement means STFC receives the same nominal pound total each year of the review period. It does not mean the council’s spending power is protected against inflation, energy costs, or currency movements — all of which have moved sharply against STFC since the settlement was agreed in late 2025.
Why does a flat budget still mean real-terms cuts?
A flat cash budget produces a real-terms cut whenever the cost of doing the same work rises faster than the funding provided. STFC executive chair Prof Sir Ian Chapman told the House of Commons Science, Innovation and Technology Select Committee on 3 February 2026 that the council’s underlying cost base, not its cash allocation, is what has grown.
- Inflation has raised the cost of staff, materials, and facility operations across the review period.
- Energy costs for running large national facilities, including neutron and light sources, have risen substantially since the settlement was fixed.
- Unfavourable exchange rates have pushed up the sterling cost of STFC’s international subscriptions, including its treaty-bound financial commitment to CERN.
International subscription costs are fixed by treaty obligation, so STFC cannot renegotiate them downward. The council instead closes the gap by reducing what remains discretionary: domestic research grants and facility operating budgets.
How much is STFC cutting from grants and facilities?
STFC must deliver £162 million in cumulative cost reductions by 2029–30, according to Research Professional News reporting on 28 January 2026, later confirmed by Chapman in an open letter to the research community on 1 February 2026. The two largest elements of STFC’s research funding — external grants and national facilities — are each absorbing cuts of roughly £38 million.
| Cost pressure element | Amount | Source |
|---|---|---|
| Total cost reductions required by 2029–30 | £162 million | Research Professional News, 28 Jan 2026; UKRI CEO open letter, 1 Feb 2026 |
| Cut to national scientific facilities | ~£38 million | Research Professional News, 28 Jan 2026 |
| Cut to external research grants | ~£38 million | Research Professional News, 28 Jan 2026 |
| Absorbed via UKRI-wide efficiency savings | ~£100 million | Sir Ian Chapman, Science, Innovation and Technology Committee, 3 Feb 2026 |
Particle physics, astronomy, and nuclear physics — collectively STFC’s PPAN portfolio — were asked to model reductions of 20%, 40%, and 60% against grant budgets, so project leaders could identify which activities become non-viable at each threshold, per the Campaign for Science and Engineering’s (CaSE) analysis published 3 February 2026.
By mid-2026 the realised outcome had come into focus: the Institute of Physics reported that STFC cut around 15% from research grants, with an estimated 220 to 260 researcher jobs lost and several collaborative projects paused or cancelled. Diamond Light Source and the ISIS Neutron and Muon Source were separately asked to model facility cuts of up to 20%, and STFC’s leadership has said withdrawing from a Cern-hosted project would weaken the UK’s international standing in physics.
How does this fit UKRI’s wider 2026 funding restructuring?
STFC’s settlement sits inside a much larger change to how UKRI allocates its entire budget. In November and December 2025, the Department for Science, Innovation and Technology (DSIT) and UKRI announced a new three-“bucket” funding model, replacing the council-by-council allocation approach used since UKRI’s creation in 2017.
| Funding bucket | Approximate share of UKRI budget | Purpose |
|---|---|---|
| Curiosity-driven research | ~50% | Applicant-led, discovery research |
| Strategic government and societal priorities | ~25% | Missions aligned to government priorities |
| Supporting innovative companies | ~25% | Business-facing innovation funding |
UKRI’s total public research and development funding is set to grow toward £10 billion a year by 2030. Chapman told the select committee that the split between the three buckets mirrors the historic balance across curiosity-led, strategic, and business-facing research, though UKRI has acknowledged that direct year-on-year comparisons with the pre-2026 council model are not straightforward, because the accounting basis has changed.
This is the key distinction for readers tracking broader “ukri budget 2026” and “ukri budget allocation” coverage: the overall UKRI pot is growing, but STFC’s specific pressures — facility running costs and treaty-bound international subscriptions — sit outside the discretionary allocation that the three buckets redistribute, so bucket-level growth does not resolve them.
Frequently asked questions
Why is STFC facing cuts if its budget is flat?
STFC’s cash budget is not falling, but its costs are rising faster than the settlement funds. Inflation, higher electricity prices for national facilities, and unfavourable exchange rates on international subscriptions such as CERN membership mean the same cash buys less, producing a confirmed £162 million shortfall by 2029–30.
How much money will STFC cut from grants and facilities?
Research Professional News reported on 28 January 2026 that both major elements of STFC’s research funding — external grants and national facilities — face cuts of roughly £38 million each. UKRI has said it will separately absorb about £100 million of the total shortfall through efficiency savings elsewhere in its own budget.
Will UKRI’s overall research budget still increase?
Yes. UKRI’s total public R&D funding is set to rise toward £10 billion a year by 2030 under the restructured three-bucket funding model announced by DSIT and UKRI in late 2025. That overall growth does not offset STFC’s specific cost pressures, which stem from facility running costs and treaty-bound subscriptions rather than discretionary allocation.
What this means for research administrators and funders
For research administrators and institutional leaders, the STFC settlement is a governance signal, not only a physics-community story. It shows that a headline “flat” or even “record” budget figure can mask real-terms reductions once inflation, energy, and currency exposure are accounted for.
- Grant applicants in PPAN-adjacent fields should expect continued competition for a shrinking discretionary pool through at least 2029–30.
- Institutions with STFC-funded facility access should model scenarios against the same 20/40/60% reduction bands STFC used internally.
- Research offices assessing funder risk should treat treaty-bound international subscriptions as a structural, non-negotiable cost driver rather than a variable one when judging a funder’s discretionary headroom.
UKRI has committed to greater transparency on the bucket methodology following select committee pressure but has not yet published backward-mapped comparison data that would let institutions benchmark old and new allocations directly. Research administration teams building funder-risk registers should treat this gap — and the distinction between a nominal flat budget and a real-terms cut — as a standing due-diligence item, not a one-off news item.
STFC’s experience is likely to recur across other funders as inflation-linked and currency-exposed cost bases collide with multi-year flat settlements agreed before those pressures fully materialised. The more reliable signal is the cost-basis gap STFC has now made explicit: £162 million by 2029–30, split roughly evenly between facilities and grants, with UKRI itself absorbing the remainder through internal efficiency.
