CMA Vet Investigation
2026
The biggest regulatory shake-up in UK veterinary history. Everything you need to know about what the CMA found, what it means, and what happens next.
Why the CMA
Investigated UK Vets
In September 2024, the Competition and Markets Authority (CMA) launched a formal market investigation into the UK veterinary sector. This was not a routine review — it was a full-scale investigation with powers to compel evidence, interview industry leaders, and impose legally binding reforms.
The investigation was triggered by an extraordinary wave of consumer anger. During the public consultation phase in early 2025, the CMA received over 56,000 individual complaints from pet owners across the UK. This was the highest number of consumer complaints for any single market investigation in the CMA's entire history — surpassing previous records from energy, banking, and telecoms.
Pet owners reported a range of issues: prices that had risen dramatically with no apparent justification, a complete lack of price transparency, excessive fees for prescriptions that made it impossible to shop around for medications, and the discovery that their supposedly "local independent vet" was actually owned by a private equity-backed corporate group.
The CMA also noted that the UK pet population had grown significantly — with an estimated 34 million pets — making veterinary care a critical consumer market affecting millions of households.

Investigation Timeline
From initial concerns to 21 mandatory reforms — the complete chronology.
CMA publishes initial concerns about the UK veterinary market following rising consumer complaints and media reports on pricing.
CMA launches formal market investigation under the Enterprise Act 2002, appointing an independent inquiry group with full investigatory powers.
CMA gathers evidence: financial data from the six largest corporate groups, pricing data from 500+ practices, and consumer survey of 10,000 pet owners.
Public consultation opens. Over 56,000 consumers submit complaints — the most for any CMA market investigation in history.
Provisional findings published. CMA confirms: 63% price rise since 2016, 17% corporate premium, 200-400% medication markups, and lack of transparency.
Remedies consultation. CMA proposes 21 mandatory reforms covering pricing, prescriptions, ownership, consumer protection, and market oversight.
Industry submissions and hearings. Corporate groups argue reforms are disproportionate. Consumer groups and VetCost call for stronger measures.
Final decision published. All 21 mandatory reforms confirmed with phased implementation. The biggest regulatory intervention in UK vet history.
CMA Orders made, bringing the reforms into force. Phased compliance deadlines begin to apply.
Larger practices (15 or more sites) must publish standard price lists, in-practice and online, alongside ownership branding.
Smaller practices publish price lists. Full ownership disclosure required for all practices. £21 prescription fee cap takes effect for larger practices.
£21 prescription fee cap takes effect for smaller practices. All 21 reforms fully implemented. CMA begins 5-year annual monitoring programme.
What the CMA Found
The investigation revealed systemic problems across the entire UK veterinary market.
Prices rose 63% since 2016
Average vet prices increased by 63% between 2016 and 2024, while general inflation over the same period was approximately 32%. Wages grew by only 28%. The CMA concluded that the price rises were not explained by increased costs alone, but by reduced competition and market consolidation.
Corporate practices charge 17% more
Practices owned by the six major corporate groups (IVC Evidensia, CVS, VetPartners, Pets at Home, Linnaeus/Mars, Medivet) charged on average 17% more than independent practices for identical procedures. The CMA attributed this to centralised pricing strategies and private equity return requirements.
Medication markups of 200-400%
Vets mark up medications by 200-400% over wholesale cost as standard practice. Some individual medications were marked up by over 1,000%. Combined with inflated prescription fees of £20-35, pet owners were effectively locked into buying overpriced medications from the practice.
Hidden corporate ownership
Over 60% of UK practices are owned by just six corporate groups, but most retain their original local names. The CMA found that pet owners were unaware of corporate ownership in the majority of cases, making informed choice impossible. Many practices in the same town were owned by the same group, creating an illusion of competition.
No price transparency
The CMA found that virtually no practices published prices in any accessible way. Pet owners could not compare costs before choosing a vet. When they arrived for treatment, they were often not told the cost until after the procedure was complete. The CMA described this as "a fundamental failure of the market."
21 Mandatory Reforms
The CMA imposed 21 legally binding reforms across five categories. No vet practice can opt out.
Price Transparency
5 reforms: publish prices, standardise format, written estimates, online lists, upfront disclosure
Prescription Rights
4 reforms: £21 cap, mandatory offer, no penalties, clear signage
Corporate Ownership
3 reforms: disclosure, RCVS register, acquisition notification
Consumer Protection
4 reforms: complaints procedure, consent forms, cooling-off, itemised invoices
Market Oversight
5 reforms: RCVS powers, annual reviews, data sharing, insurance transparency, OOH regulation
What the Investigation
Means for Pet Owners
Compare before you commit
From December 2026 for larger practices (March 2027 for smaller ones), all practices must publish prices. You can compare costs online before choosing a vet. Use VetCost to start comparing right now.
Save on medications
The £21 prescription cap makes buying online viable for everyone. Combined with online retailer prices, you could save 30-70% on pet medications.
Know who owns your vet
Corporate ownership must be disclosed from March 2027. No more hidden ownership. You will know whether your vet is independent or part of a corporate chain.
Challenge overcharging
Itemised invoices, written estimates, and formal complaints procedures give you the tools to challenge unfair charges. If your vet breaches the rules, report them.
Frequently Asked Questions
The CMA launched a formal market investigation into UK vets in September 2024 after receiving 56,000+ complaints. It found widespread overcharging, lack of transparency, and corporate consolidation. The final decision on 24 March 2026 imposed 21 mandatory reforms.
Triggered by 56,000+ consumer complaints about excessive prices, lack of price transparency, high prescription fees, hidden corporate ownership, and inability to compare costs. This was the most complaints for any CMA market investigation ever.
Prices rose 63% since 2016 (vs. 32% inflation). Corporate practices charge 17% more. Medication markups of 200-400%. Prescription fees used as barriers. 60%+ practices corporate-owned. Zero price transparency for consumers.
They cover: price publication, standardised formats, the £21 prescription cap, mandatory prescription offers, ownership disclosure, RCVS register, complaints procedures, consent forms, itemised invoicing, written estimates, annual monitoring, and more. See our full CMA reform tracker.
Phased, with the CMA Orders made by September 2026. Price publication from December 2026 for larger practices and March 2027 for smaller ones. The £21 prescription cap from March 2027 for larger practices (15 or more sites) and September 2027 for smaller ones. Ownership disclosure by March 2027. All 21 reforms fully implemented by September 2027.
Price transparency and competition should drive prices down over time. The £21 prescription cap alone saves hundreds per year on medications. However, some costs are genuinely high due to equipment and training. The reforms target anti-competitive pricing, not all pricing.
Over 56,000 individual complaints — the most for any CMA investigation in history. This surpassed previous records from energy, banking, and telecoms investigations.
The CMA says you deserve transparency
We agree. Compare vet prices, check ownership, and save on medications — all in one place.
