The CMA Vet Reforms 2026: What They Mean for Your Pet Bills
On 24 March 2026, the Competition and Markets Authority published its final report on the UK veterinary services market — the most significant review of the sector in a generation. Here's a clear, plain-English breakdown of what's changing, when it happens, and what it means for you and your pet.
What is the CMA and why did it investigate vets?
The Competition and Markets Authority is the UK's independent regulator responsible for ensuring markets work well for consumers and businesses. It has the power to investigate entire sectors and impose legally binding remedies when it finds the market isn't functioning fairly.
The CMA launched its review of veterinary services in September 2023 after growing concern from pet owners about rising prices, a lack of transparency, and significant consolidation of practices into large corporate groups. The investigation received an extraordinary response: 56,000 replies to its initial call for information — 45,000 from the general public and 11,000 from those working in the profession.
What it found was significant. Pet owners were frequently left in the dark about who owned their practice, what treatment would cost, and what alternatives existed. Weak competition and a lack of information were pushing prices up and leaving consumers unable to make informed choices.
What is the UK vet market investigation?
The veterinary services sector in the UK is worth over £6.7 billion a year and serves around 17.2 million pet-owning households. Despite this scale, key parts of the market had been operating for decades without meaningful regulation of pricing, ownership disclosure, or consumer rights.
The six largest veterinary groups — CVS, IVC Evidensia, Linnaeus, Medivet, Pets at Home, and VetPartners — now own a substantial and growing proportion of UK practices. Many pet owners have no idea their local vet is part of a large corporate chain rather than an independent business.
The key reforms — what's actually changing
Mandatory price lists
All practices must publish a comprehensive price list covering consultations, common procedures, diagnostics, prescriptions and cremation options.
Ownership transparency
Practices must clearly display whether they are independent or part of a larger group — on signage, at the premises, and online.
Written estimates
For any treatment expected to cost £500 or more, practices must provide a written estimate in advance — plus an itemised bill afterwards.
Prescription fee caps
Written prescription fees are now capped at £21 for the first medicine and £12.50 for any additional medicines — down from some practices charging £40+.
Price comparison website
The RCVS must share practice data — including pricing — with third-party comparison sites, making it genuinely possible to compare vets in your area.
Independent advice protection
Practices must have written policies to ensure vets can offer independent, impartial advice — free from undue commercial pressure from corporate owners.
On prescriptions specifically: Over 70% of pet owners currently buy long-term medication from their vet practice — even though many could save £200 or more per year by buying online with a written prescription. Under the new rules, practices must tell you that a written prescription is available.
When does all this happen?
What about regulation and oversight?
The current legal framework governing veterinary services is over 60 years old. It applies to individual vets but not to veterinary businesses — meaning the corporate groups that now own the majority of UK practices have largely operated outside meaningful regulatory oversight.
The CMA has backed the government's proposed reforms to the Veterinary Services Act, which would — for the first time — make veterinary businesses as well as individual practitioners accountable to an independent regulator. This would cover consumer protection, fair competition, and clinical standards.
The RCVS (Royal College of Veterinary Surgeons) will take a central role in monitoring compliance and running the data comparison service. The cost of this — estimated at £450–£550 per practice per year — will be funded by a levy on veterinary businesses, scaled to the size of the business.
What this means in practice: For the first time, a vet practice can be held accountable as a business — not just its individual vets. Corporate groups that impose commercial pressure on clinical decisions, or that obscure ownership from customers, will face regulatory consequences.
What it means for pet owners — right now
The most immediate practical step you can take is this: find out whether your vet practice is independently owned or part of a corporate group. You can check the Companies House register, look at the RCVS Find a Vet database, or simply ask your practice directly.
Once price lists become mandatory — which will begin rolling out for large groups before the end of 2026 — you'll be able to compare your current vet's prices against local alternatives for the first time. If you're paying significantly more than nearby practices for routine services, you'll have the information to make a different choice.
And if your pet is on long-term medication, ask for a written prescription now. Your vet cannot unreasonably refuse — and the prescription fee is now capped at £21.
What it means for vet practices
For independent practices, the reforms are a genuine opportunity. Ownership transparency means that pet owners who value independent care can now find and choose you more easily. Publishing clear prices doesn't just satisfy regulation — it builds trust.
For corporate groups, the pressure is greater. Price lists, ownership labelling, written estimates, and independent advice policies all require meaningful operational change — and compliance will be monitored by the RCVS.
