National Diabetes Audit, Non-Diabetic Hyperglycaemia, 2019- 2020, Diabetes Prevention Programme, Data Release
From Jan 2019 to March 2020, 2.1 million people in England were recorded as having non-diabetic hyperglycaemia, an increase from 1.8 million in 2018-19. The difference is most likely due to an increase in the recording of the diagnosis during 2019-20.
