Authorisation Looks Like.
The headline facts every importer, procurement lead and applicant should know about the MHRA WDA(H) framework.
a company touch medicines.
A Wholesale Dealer Authorisation (WDA) is the company licence granted by the UK Medicines and Healthcare products Regulatory Agency (MHRA) that legally permits a business to procure, store, supply or export medicines. Asking what is a WDA licence is essentially asking who is allowed to handle licensed pharmaceuticals in the UK supply chain, and the answer is: only WDA holders.
The phrase WDA meaning pharma uses is therefore very specific. It is not a permit to sell medicines to the public, that is a community or hospital pharmacy registration with the General Pharmaceutical Council (GPhC). It is not a Marketing Authorisation, which sits with the manufacturer or sponsor that owns the product right. A WDA is the wholesale handling licence that sits between manufacturer and dispensing pharmacy, hospital, exporter or other authorised recipient. International readers searching wda license uk (US spelling) will find exactly the same licence, MHRA does not maintain a separate framework under that spelling.
The licence comes in two main forms. WDA(H) authorises wholesale dealing in human medicines. WDA(V) authorises wholesale dealing in veterinary medicines and is regulated by the Veterinary Medicines Directorate (VMD). Most UK pharmaceutical wholesalers and exporters, including Euro Biom, hold WDA(H). Companies that handle both human and veterinary medicines require both licences.
When people ask what is WDA in pharmaceutical industry terms, the short answer is: the licensed gatekeeper of the wholesale supply chain. Without a WDA, no company in the UK can lawfully buy, store, dispatch or export licensed medicines. Holding one means MHRA has inspected the site, approved the quality system, accepted the named Responsible Person, and judged the operation fit to handle medicines under GDP.
Supply Chain Holds One.
If your business buys, sells, stores or moves licensed medicines in the UK, you almost certainly need a Wholesale Dealer Authorisation. The categories below are the most common.
Authorises You to Do.
A WDA is not a blanket permit. Every WDA lists specific authorised activities and product categories. MHRA grants only the scopes that the site and Quality Management System support.
Important: WDA holders do not own Marketing Authorisations. A WDA permits the wholesale handling of medicines that already hold a valid MA owned by a manufacturer or sponsor. WDA holders cannot vary product specifications, change labelling beyond authorised translation requirements, or relabel for primary indications. Where a product is not registered in the destination market, the importing country's named-patient or import-permit pathways apply.
to Granted Licence.
The route from intention to operational WDA. Realistic timeline is three to nine months end to end, depending on site readiness and inspection scheduling.
WDA licence requirements at a glance: GDP-compliant warehouse with monitored storage, named qualified Responsible Person, documented Quality Management System, supplier and customer bona fide procedures, batch traceability, recall procedure, self-inspection programme, and the published MHRA application fee. Specific requirements vary by scope and product category. MHRA publishes the current fee structure on GOV.UK.
The four controls every
WDA holder must demonstrate.
A WDA is granted on the back of demonstrable GDP compliance. Each of these four pillars is examined at pre-licence inspection and at every subsequent MHRA visit.
Qualified Responsible Person (RP)
Every WDA holder must name a Responsible Person with the qualifications and industry experience required under the Human Medicines Regulations 2012. The RP is personally accountable for GDP compliance, supplier and customer verification, product release for sale, and any decision regarding suspect or recalled product.
Calibrated Storage and Temperature Mapping
The authorised storage area must be temperature-mapped, continuously monitored, and equipped with calibrated probes. Cold chain areas require validated 2-8 degC monitored storage. Mapping is repeated periodically and on any significant equipment or layout change.
Quality Management System with SOPs
A documented Quality Management System governs every operational activity, from goods receipt and storage through dispatch, returns, complaints, recalls, self-inspection and deviation management. Every SOP must be controlled, version-managed and accessible to staff at the workstation.
Bona Fide Verification
WDA holders must verify the authorisation status of every supplier and every customer before transacting. Suppliers must hold an MIA or WDA. Customers must be authorised recipients: WDA holders, registered pharmacies, hospitals, dispensing doctors or, for export, recognised overseas buyers. This is the single biggest enforcement focus.
Wholesale Dealer Online.
Every WDA holder in Great Britain is listed on the MHRA public register, published on GOV.UK. Before transacting with a UK wholesaler or exporter, any procurement team can and should run a WDA licence check.
The register is searchable by company name, licence number or site address. It lists the licence reference (for example, WDA(H) 59239), granted date, current status, authorised scope and the named site. A genuine UK wholesaler will display their WDA number openly on their website footer, quotations and invoices.

UK Licence Framework Fits Together.
A WDA does not sit in isolation. It is one of several MHRA licences that together regulate every stage of the UK medicines supply chain. Understanding where WDA stops and other licences start prevents costly compliance mistakes.
WDA vs MIA
A Manufacturer's / Importer's Authorisation (MIA) permits the actual manufacture of medicines, or their importation from outside the UK as a finished or bulk product, against a Marketing Authorisation. A WDA, by contrast, only authorises the onward wholesale handling of medicines that have already been manufactured and released. An MIA holder can manufacture; a WDA holder cannot. Many companies hold both licences for different legal entities or sites under one corporate group.
WDA vs MS Manufacturing Licence
A Manufacturer's Licence (MS) authorises the manufacture of medicines prepared for individual patient prescription requirements. A WDA only authorises the supply of medicines, not their manufacture. UK suppliers commonly hold a WDA(H) for procurement and supply, alongside an MS if they also manufacture. Euro Biom holds a WDA(H) only: we trade exclusively in UK-licensed medicines and do not manufacture.
WDA vs GPhC Pharmacy
A registered pharmacy with the General Pharmaceutical Council (GPhC) supplies medicines to the public against prescriptions or as a retail pharmacy. A WDA-licensed wholesaler supplies medicines only to authorised recipients (other WDA holders, registered pharmacies, hospitals, dispensing doctors, exporters), and never directly to patients. The two frameworks are distinct and have separate professional accountabilities, the GPhC route via the pharmacy Superintendent, the WDA route via the Responsible Person.
WDA vs Broker Registration
Brokers, companies that arrange wholesale transactions of medicines without ever physically holding them, are regulated under a separate brokering registration in the Human Medicines Regulations 2012, not a WDA. The distinction is physical possession. If your business ever stores or dispatches medicines, even from a contract warehouse, you need a WDA. If your business only arranges transactions between authorised parties, a brokering registration is the correct route.
Common Misconceptions About a WDA Licence
Reality: WDA holders cannot vary product specifications or alter primary labelling. Only the Marketing Authorisation Holder can change a label; WDA holders may translate or apply secondary stickers under specific MHRA-approved procedures.
Reality: A WDA is a live licence. It can be varied, suspended or revoked. MHRA re-inspections happen on a risk-based cycle, typically every two to three years, and any non-compliance can put the licence at risk.
Reality: A WDA is site-specific. Each authorised site is named on the licence with its own scope. Operations at an unauthorised site, even within the same company, are non-compliant.
Reality: A WDA never authorises direct supply to patients. Public-facing supply requires a separate GPhC pharmacy registration. WDA holders supply only authorised recipients, never the patient directly.
