Pet prescription fees in the United Kingdom will be capped under new rules introduced by the Competition and Markets Authority (CMA), following findings that some veterinary practices were overcharging customers.
Under the reforms, pet owners will pay no more than £21 for prescriptions. Veterinary clinics will also be required to publish clear price lists for services such as consultations, treatments, diagnostic tests and cremation options.
The CMA said the changes aim to improve transparency and help pet owners make informed decisions, especially after a three-year investigation revealed widespread pricing concerns.
Vets must now inform customers if they can save money by purchasing medication online using a prescription. Practices will also be required to disclose whether they are independently owned or part of a larger corporate group.
Additionally, pet owners must be given a written estimate for treatments expected to cost £500 or more, along with a detailed bill. Emergency care will be the only exception.
A new comparison website will also be launched to help customers compare veterinary services more easily.
CMA inquiry chair Martin Coleman said the current system had left many pet owners unclear about pricing, ownership and treatment options, sometimes facing bills running into thousands of pounds.
The new rules, set to take effect on 23 September, are designed to increase transparency, build trust in veterinary services and protect pet owners from excessive costs.
