Apply for Your Wholesale Distribution Authorisation (WDA) with Confidence

Launching or expanding a pharmaceutical wholesale business in the UK? One of your first and most important steps is applying for a Wholesale Distribution Authorisation (WDA) through the Medicines and Healthcare products Regulatory Agency (MHRA). Without it, you legally cannot procure, store, supply, or export medicinal products.

At GDP Pharma Consulting, we offer complete support throughout the WDA application process—from business model design to inspection readiness—ensuring you achieve full GDP compliance, avoid delays, and maintain long-term regulatory success.

What is a WDA
(Wholesale Distribution Authorisation)?

A WDA(H) allows you to legally distribute human medicinal products within the UK and internationally. It is a legal requirement under the Human Medicines Regulations 2012, and a core part of MHRA oversight into medicine safety and supply chain integrity.

Whether you need a WDA(H) (for human medicines) or a WDA(V) (for veterinary), the process is technical and highly regulated—and even small errors in your application or site setup can lead to delays or rejections.
