What the CMA's Veterinary Reforms Mean for UK Pet Owners

Why a competition regulator looked at vets

The Competition and Markets Authority (CMA) is the UK's competition regulator. In 2023 it began what would become a two-year market investigation into veterinary services for pets, prompted by concerns about consumer detriment — vague pricing, limited ability to compare practices, and substantial growth in the share of practices owned by a small number of large veterinary groups.

The investigation drew responses from thousands of pet owners, vets, and practices. The CMA's 24 March 2026 Final Report concluded that the market doesn't work as well as it should for consumers, and proposed 14 remedies aimed at making information clearer and comparison easier. Pet owners are the primary beneficiaries; practices face new disclosure obligations.

This is a regulatory market remedy, not legislation that changes how vets practise medicine. Clinical standards remain governed by the Royal College of Veterinary Surgeons. The CMA reforms are about transparency, comparison, and choice.

The four headline changes for pet owners

1. Mandatory comprehensive price lists

Every UK veterinary practice will be required to publish a standardised list of prices for common services — consultations, vaccinations, neutering, dental procedures, and a defined set of routine items. Practices currently vary widely in how much pricing they publish publicly; under the new rules the format becomes consistent. A £80 consultation in one practice will compare meaningfully to a £55 consultation in another.

A centrally-mandated price comparison website is also expected, allowing owners to compare practices in their area without visiting each website individually.

2. Capped prescription fees

Many pet owners have noticed prescription fees rising over recent years. The CMA found that practices were sometimes charging significant mark-ups for issuing a prescription that allowed owners to buy medication elsewhere — effectively a barrier to shopping around.

The Final Report proposes capping prescription fees at £21 for the first item and £12.50 for each additional item (VAT-inclusive, with an annual CPI adjustment). Large veterinary groups are expected to implement the cap from March 2027; smaller independent practices from September 2027.

For a pet on chronic medication this can produce meaningful savings, because once the cap is in force it becomes more economical to request a written prescription and source the medication from an online pharmacy.

3. Clearer ownership disclosure

If a practice belongs to a large veterinary group, that fact will need to be visible to consumers — typically on the website and at the practice itself. The Final Report identifies a small number of large groups as owning a substantial share of UK veterinary practices, and the CMA's view is that the corporate structure isn't always obvious to a customer making a choice.

This is about disclosure, not prohibition. Both group-owned and independent practices remain valid choices; the rule ensures pet owners know which they're choosing.

4. Standardised complaint processes

Practices will be required to publish their complaint process clearly, with defined timeframes for response and a route for escalation. This was identified by the CMA as an area where many pet owners reported difficulty navigating unsatisfactory situations.

Three practical scenarios for pet owners

Scenario 1 — Choosing a new vet

Until mandatory price lists arrive, comparing practices on cost remains harder than it should be. The practical workaround is to phone two or three practices on your shortlist and ask for the cost of a routine consultation, the standard annual booster vaccinations for your pet, and a typical neutering procedure where relevant. Most practices will quote these readily.

Once mandatory lists are live, the comparison becomes a 5-minute exercise. Our guide to choosing a vet in the UK walks through the full decision framework — costs, location, standards, and the visit itself.

Scenario 2 — Querying a bill

If a bill is significantly higher than expected, asking the practice for an itemised breakdown is standard and entirely reasonable. Once price transparency rules are in force, comparing the published list to what you were charged becomes straightforward. Until then, requesting a written estimate before any non-emergency procedure remains the strongest protection.

Scenario 3 — Switching practices

The new ownership-disclosure rules may, over time, prompt some owners to reconsider where their pet is registered — particularly if a long-trusted independent has changed hands and joined a larger group. Switching is generally straightforward; the procedure is set out in our guide to switching vets in the UK.

How FetchRated relates to the CMA reforms

The CMA's analysis identified independent comparison infrastructure as part of the answer to the consumer-information problem in this market. FetchRated is, separately, building that infrastructure — a UK directory of veterinary practices with verified reviews and an independent assessment methodology. Our methodology page sets out exactly what we do (and don't) measure.

The CMA reforms and independent comparison are complementary: regulatory transparency makes the data comparable; independent verification makes the comparison meaningful.
