The NHS Business Services Authority (NHSBSA) received your request on 15 February 2026.

We have handled your request under the Freedom of Information Act 2000 (FOIA).

Our response

I can confirm that the NHSBSA holds the information you have requested and a copy of the information is attached.

Please read the below notes to ensure correct understanding of the data.

NHSBSA

NHS Prescription Services process prescriptions for Pharmacy Contractors, Appliance Contractors, Dispensing Doctors and Personal Administration with information then used to make payments to pharmacists and appliance contractors in England for prescriptions dispensed in primary care settings (other arrangements are in place for making payments to Dispensing Doctors and Personal Administration). This involves processing over 1 billion prescription items and payments totalling over £9 billion each year. The information gathered from this process is then used to provide information on costs and trends in prescribing in England and Wales to over 25,000 registered NHS and Department of Health and Social Care users.

Data Source: ePACT2

Data in ePACT2 is sourced from the NHSBSA Data Warehouse and is derived from products prescribed on prescriptions and dispensed in the Community. The data captured from prescription processing is used to calculate reimbursement and remuneration. It includes items prescribed in England, Wales, Scotland, Northern Ireland, Guernsey / Alderney, Jersey, and Isle of Man which have been dispensed in the community in England. English prescribing that has been dispensed in Wales, Scotland, Guernsey / Alderney, Jersey, and Isle of Man is also included.

The Data excludes:

• Items not dispensed, disallowed and those returned to the contractor for further clarification.

• Prescriptions prescribed and dispensed in Prisons, Hospitals and Private prescriptions.

• Items prescribed but not presented for dispensing or not submitted to NHS Prescription Services by the dispenser.

Time Period

November and December 2025 (aggregated monthly). Last two reporting periods.

Data

The dataset is limited to those items prescribed and dispensed in England and shows the prescribing ICB.

BNF Code

The BNF Code is a 15-digit code in which the first seven digits are allocated according to the categories in the BNF, and the last 8 digits represent the medicinal product, form, strength and the link to the generic equivalent product. NHS Prescription Services has created pseudo BNF chapters, which are not published, for items not included in BNF chapters 1 to 15. Most of these items are dressings and appliances which NHS Prescription Services has classified into four pseudo BNF chapters (20 to 23).

Gender

Patient gender has been reported using the latest patient gender information held by the NHSBSA Information Services data warehouse at the time that the data was extracted. This uses information from either the most recent Electronic Prescription Service (EPS) message or from the last time that NHSBSA received data about the patient's gender from NHS Personal Demographics Service.    

Gender is either: Male, Female, Not Known (where no information is held) or Indeterminate (where information is held which does not confirm either Male or Female).

Patient Identification

Where patient identifiable figures have been reported they are based on the information captured during the prescription processing activities.  Please note, patient details cannot be captured from every prescription form and based on the criteria used for this analysis, patient information (age and gender) was only available for 98.55% of prescription items.
