Change to the audit period
From the 2024/25 audit year, the NDA will report on a 12 month audit period, rather than a 15 month audit period. Where the audit period was from January of year 1 to March of year 2, it will now be April of year 1 to March of year 2. As such NDA data from 2024/25 onwards is not directly comparable to any published NDA figures from previous audit years.

Summary
The worksheets include data for all ICBs and GP practices in England within the February 2025 extraction of NDA data (April to December 2024 data). These data undergo further validation processes at the end of each audit year when data from specialist services are added in, at which point the data are considered to comprise the full annual dataset to be used in the annual NDA publications.
Data for Local Health Boards (LHBs) in Wales and specialist diabetes services in England are not included in the quarterly publications. Their 2024-25 data (for the full audit period April 2024 to March 2025) will be extracted as part of the final NDA 2024-25 collection and reported in the NDA 2024-25 full audit period data release, scheduled for late 2025.
Disclosure control has been applied to mitigate the risk of patient identification. Zeros are reported, and all numbers are rounded to the nearest 5, unless the number is 1 to 7, in which case it is rounded to ‘5’. This allows for more granular data to be made available, and also for data for all GP practices to be made available. Percentages where the denominator is less than or equal to 20 are not reliable and have therefore not been calculated in this release.
We are aware that some pathology laboratories have been affected by HbA1c analyser issues in 2024/25. These may have resulted in higher HbA1c results than would otherwise have been expected.
Highlights
6,291 practices participated in this third data extract of the 2024-25 audit period
Which represents 98.7% of the eligible GP practices in England
