The U.K. has fewer radiologists per head of population than most comparable European countries, according to the Royal College of Radiologists' (RCR) 2025 Clinical Radiology Census. A gap that helps explain why the service is struggling to keep pace with rising imaging demand.
The U.K. has 10.3 clinical radiologists per 100,000 population, counting consultants, SAS doctors, and residents together. That sits below the OECD average of 12.8 and below the 27-nation EU average of 12.7. Of the UK's regions, only London (14.1) exceeds the OECD benchmark.
The shortfall is starker against individual European systems. The census places the U.K. behind Spain (12.1), Portugal (14.8), Denmark (15.8), Finland (16.3), and well behind Italy (23.3) and Sweden (27). Only Malta, at 6.7 per 100,000, ranks lower among the countries the RCR cites. France, at 13.1, also outstrips the U.K.
These figures align with the wider European picture. The EU-funded EU-REST study, led by Prof. Adrian Brady and published in Insights into Imaging, found an EU-wide ratio of 127 radiologists per million inhabitants, equivalent to 12.7 per 100,000, but with enormous variation between member states, from 51 per million in Bulgaria to 270 per million in Sweden. More than half of EU countries fall below their own average.
Expand specialty training places
The census frames the staffing gap as a direct driver of the U.K.'s diagnostic pressures. With demand for complex imaging growing roughly twice as fast as the workforce, departments are leaning on outsourcing, insourcing and locums, measures that cost a record £362 million in 2025.
The RCR's central recommendation is to expand specialty training places to close the consultant shortfall, which it puts at 32%, or 2,313 whole-time radiologists.
A note on methodology: per-capita comparisons can flatter or penalize systems depending on how each counts its workforce and how much of it works full time.
The RCR stresses that 41% of U.K. consultants now work less than full time, so headcount-based ratios may understate the true capacity gap rather than overstate it.
