The activities of other funders, including US-based research institutes affected by funding cuts from President Donald Trump’s administration, might have also affected UKRI application volume, with more researchers in the United States looking outside the country to secure funding.

Demand management

In 2022, the Technopolis Group — an international research and consulting organization — published a review of the UKRI’s response to the substantial bump in applications and the expedited review timelines in the COVID-19 pandemic. During this period, UKRI staff and reviewers faced widespread burnout, according to the report, and more than one-third of awardees had experienced delays while waiting for a decision.

A number of UKRI councils have adopted demand-management policies to reduce pressure on their peer-review systems as applications increase. In 2015, the Natural Environmental Research Council (NERC) implemented a demand-management policy limiting the number of applications from individual institutions on the basis of success rate: those with a low success rate were subjected to a cap on the number of applications they could submit. Although this is not the only way to reduce pressure on peer-review and grant systems, it tends to lead to more-robust applications, says Riley. She says other councils could follow suit.

A number of councils, including the NERC and the Engineering and Physical Sciences Research Council, no longer allow uninvited resubmissions, as of this year. The Biotechnology and Biological Sciences Research Council does not accept applications that have already been peer reviewed or are under peer review by another funding body or research council.

This new policy has attracted criticism that the resubmission policies could prevent researchers from improving grant proposals on the basis of feedback from the rejection. “This is a huge mistake. My experience on NERC panels is that resubmissions score higher and are more likely to be funded: the review process improves good proposals that should not be lost (along with the time spent on them),” argued Jen Gill, an ecologist at the University of East Anglia, UK, on Bluesky.

A UKRI spokesperson told Nature’s reporter that the body would “continue to review and revise [grant funding] mechanisms including demand management and innovative assessment processes”. “We recognize that the high demand for funding, of all types, affects success rates, and reflects high investment from the sector — from applicants to research offices to reviewers.”

A more radical response would be to do away with grants and focus on block funding, lump sums delivered to institutions rather than through competitive, researcher-targeted grants, says Mike Thelwall, a data scientist at the University of Sheffield, UK. Thelwall — whose published work includes papers on rethinking peer review and the use of large language models in research — says that the rise in applications indicates a “huge increase in the amount and cost of work for academics completing these applications”. “[Researchers] must be spending less time either teaching or doing research, and spending more time on writing these grants,” he says. Over the coming years, artificial-intelligence systems could help to increase the efficiency of the proposal-writing process, he adds, but they won’t stump up more funding.
