Your Comprehensive Guide to WDA(H)Understanding Wholesale Dealer's Licence (WDA(H))
A Wholesale Dealer's Licence (WDA(H)) is a mandatory requirement for businesses involved in the storage or distribution of medicinal products for human use in the UK. Issued by the Medicines and Healthcare products Regulatory Agency (MHRA), this licence ensures that wholesale distribution activities comply with Good Distribution Practice (GDP).
What is a WDA(H)?
The WDA(H) is a legal requirement for any entity storing medicinal products before supplying them to others, with limited exceptions. It exists to guarantee that medicines remain safe, effective, and of high quality throughout the distribution chain. This licence covers wholesale distribution activities including procurement, holding, storage, and distribution of medicinal products.
Key Point: Even healthcare professionals who stock medicines for their own patients but also supply to other healthcare providers may need a WDA(H).
Who Needs a WDA(H)?
You may need a WDA(H) if your business:
- Imports medicinal products from outside the UK
- Distributes medicines to pharmacies, hospitals, or other healthcare providers
- Manufactures medicines and also distributes them to third parties
- Stores medicines prior to distribution
- Sells medicines online to UK customers
The following entities are generally exempt:
- Pharmacies supplying medicines directly to patients for whom they have been prescribed
- Hospitals supplying medicines for their own patients
- Doctors or dentists supplying medicines for their own patients
- Veterinary practices supplying medicines for animals under their care
- Practices that only handle Schedule 1 controlled drugs
Licensing Requirements
To obtain a WDA(H), businesses must meet specific requirements regarding personnel, premises, systems, and documentation:
Personnel Requirements
- Appointment of a Responsible Person (RP) with appropriate qualifications and experience
- Sufficient staff with appropriate training and skills
- Documented organizational structure and responsibilities
Premises Requirements
- Suitable storage facilities appropriate for the types of medicines stored
- Equipment for temperature monitoring and control where required
- Adequate security measures
- Designated areas for receiving, storage, and dispatch of medicines
- Separate areas for returned or recalled products
System Requirements
- Quality Management System compliant with GDP
- Standard Operating Procedures covering all distribution activities
- Traceability system for all medicinal products
- Process for handling discrepancies, complaints, and recalls
- Self-inspection schedule
The Responsible Person (RP)
At least one Responsible Person must be named on the WDA(H). The RP has overarching responsibility for ensuring the licensed operation complies with GDP requirements. Key responsibilities include:
- Maintaining and improving the quality system
- Ensuring all staff receive appropriate training
- Approving suppliers and customers
- Monitoring environmental conditions in storage areas
- Conducting or overseeing self-inspections
- Implementing recall procedures when necessary
The RP must be continuously available during business hours either in person or through their deputies, and must have successfully completed an approved WDA(H) RP examination.
Application Process
The application process for a WDA(H) involves several steps:
1. Preparation
Ensure your business meets all requirements before applying, including appointing a qualified RP, preparing suitable premises, and developing appropriate quality systems and SOPs.
2. Application Submission
Complete the WDA(H) application form from the MHRA website, providing details about your business, premises, RP, and activities to be undertaken.
3. Fee Payment
Pay the required application fee. Fees vary based on the type of licence and number of sites being licensed.
4. MHRA Inspection
Once your application is received, an MHRA inspector will contact you to arrange an inspection of your premises and operations to verify GDP compliance.
5. Licence Issuance
If the inspection is satisfactory, the MHRA will issue your WDA(H). The licence will detail the specific activities and premises covered.
Licence Categories and Costs
| Licence Category | Description | Annual Fee |
|---|---|---|
| A | Standard wholesale distribution of medicinal products | 1,450 |
| B | Distribution of narcotic and psychotropic substances | 2,040 |
| C | Distribution of radiopharmaceuticals | 1,450 |

Maintaining Compliance
Once you have your WDA(H), you must maintain compliance with GDP through:
- Regular self-inspections (at least annually)
- Performance of SOP reviews and updates as needed
- Maintenance of temperature monitoring records
- Staff training records
- Receipt and dispatch records for traceability
- Documentation of any deviations or quality issues
Common Pitfalls
Many WDA(H) holders face compliance challenges with:
- Inadequate temperature monitoring systems
- Poor documentation practices
- Lack of regular self-inspections
- Failure to maintain appropriate storage conditions
- Insufficient staff training
- Non-compliance with Falsified Medicines Directive requirements
Revocation and Enforcement
The MHRA can suspend or revoke a WDA(H) if there is evidence of non-compliance with GDP or risk to the quality of medicines. Enforcement actions may include:
- Issuing warning letters with requirements for corrective actions
- Adding special conditions to the licence
- Temporarily suspending the licence
- Revoking the licence entirely
- Criminal prosecution for serious breaches
Looking Forward
The pharmaceutical distribution landscape is evolving, with increasing focus on patient safety, security of the supply chain, and regulatory compliance. The Falsified Medicines Directive introduces additional requirements for wholesale dealers, including:
- Verification of safety features (anti-tampering devices and unique identifiers)
- Enhanced systems for reporting suspected falsified medicines
- Higher standards for documentation and traceability
For anyone looking to enter or remain in the pharmaceutical wholesale distribution sector, understanding and maintaining WDA(H) requirements is essential for both regulatory compliance and business success.
