Wholesale dealing plays a critical role in the UK pharmaceutical supply chain. If you plan to distribute medicines to pharmacies, hospitals or other wholesalers, you must obtain a Wholesale Dealer Authorisation (WDA) from the Medicines and Healthcare products Regulatory Agency (MHRA).
This guide explains the licensing requirements, inspections, compliance obligations and ongoing responsibilities.
Wholesale dealing involves:
Procuring licensed medicines
Supplying them to pharmacies, hospitals, or other authorised businesses
Importing or exporting medicines for commercial supply
Operating as a short-line or full-line wholesaler
Unlike a retail pharmacy (regulated by the General Pharmaceutical Council), wholesale dealers are regulated directly by the MHRA.
A Wholesale Dealer Authorisation (WDA) allows a business to:
Buy medicines for resale
Distribute medicines within the UK
Export medicines outside the UK
You can apply for a WDA via GOV.UK:

Key Requirements for a WDA Licence
1️⃣ Appointment of a Responsible Person (RP)
Every wholesale dealer must appoint a Responsible Person (RP) who:
- Has appropriate knowledge of pharmaceutical distribution
- Ensures compliance with Good Distribution Practice (GDP)
- Maintains oversight of quality systems
2️⃣ Compliance with Good Distribution Practice (GDP)
Wholesale dealers must comply with the GDP guidelines covering:
- Temperature control and monitoring
- Secure storage and segregation
- Supplier and customer qualification

3️⃣ Suitable Premises
Premises must include:
- Secure storage areas
- Temperature mapping and monitoring systems
- Controlled drug security (if applicable)
- Documented cleaning and pest control procedures
- IT systems for batch traceability
The Licensing Process
The application process includes:
- Submission of online application via MHRA
- Payment of the application fee
- Submission of quality system documentation
- Pre-licence inspection by MHRA
- Approval and licence issuance
After approval, your WDA licence:
- Does not expire automatically
- Is subject to risk-based MHRA inspections
- Requires annual fee payments
- Can be suspended or revoked if non-compliance is identified

Ongoing Compliance Obligations
Wholesale dealers must:
- Maintain continuous GDP compliance
- Notify MHRA of changes (RP, premises, activities)
- Keep training records
- Maintain deviation and CAPA systems
- Conduct self-inspections
Failure to comply may result in enforcement action.
Common Mistakes New Wholesale Dealers Make
- Underestimating inspection preparation
- Inadequate SOP documentation
- Poor temperature validation
- Lack of RP oversight evidence
- Weak supplier qualification procedures
This is where many applications are delayed or rejected.
Is Wholesale Dealing Right for Your Business?
Becoming a wholesale dealer requires:
- Significant infrastructure investment
- Strong regulatory knowledge
- Ongoing inspection readiness
- Quality management systems
However, when properly established, it offers scalable B2B revenue opportunities within the UK pharmaceutical sector.
