I authorise wholesale supplies of veterinary medicines to a charity/business premises; are they veterinary practice premises?

Yes; the charity/business premises are likely to be considered veterinary practice premises for the purposes of supplies of those veterinary medicines to the charity/business, for animals owned by the charity. (You or the charity may register the premises with the RCVS).

NB. The Veterinary Medicines Regulations provide that a veterinary surgeon may supply veterinary medicines (for example, POM-Vs after the clinical assessment of an animal under his or her care) ‘irrespective of who owns [those medicines].’ (Schedule 3 paragraph (6) (b))

If you authorise supplies of medicines to the charity/business, you are responsible for the medicines, for example, correct storage and annual audit; responsibility may be shared with the charity/business.
