The lowdown on new vet rules (and what they mean for cat parents)

Big changes are coming to vet care in the UK – and if you’ve ever felt confused by pricing, surprised by a bill or unsure about your options, this one’s for you.

On 24 March 2026, the Competition and Markets Authority (CMA) published its final report into UK veterinary services, following a huge investigation with over 56,000 responses from pet owners. The result? A set of legally binding reforms designed to make vet care more transparent, fair and easier to navigate.

Here’s what’s changing – and why it matters for you and your cat.

Clearer pricing (no more guesswork)

One of the biggest shake-ups is around pricing transparency.

Vet practices will now need to publish clear, standardised price lists for everything from consultations and vaccinations to surgeries and end-of-life care. These prices must be easy to find (no digging around websites) and regularly updated.

They’ll also need to show prices for common treatments like parasite prevention, plus clearly explain what’s included in any care plans — and how those savings are actually calculated.

What it means for you: You’ll be able to check costs upfront, compare options more easily and make decisions without feeling in the dark.

Upfront estimates for bigger treatments

If your cat needs treatment expected to cost £500 or more, your vet must provide a written estimate before going ahead.

And if the cost increases significantly (by 20% or £500 – whichever is lower), they’ll need to update you before continuing (unless it’s an emergency).

What it means for you: No more unexpected “by the way…” moments at the end of a visit. You’ll know what you’re signing up for – and have a chance to ask questions or explore alternatives.

Itemised bills you can actually understand

Vets will now need to provide fully itemised bills, showing exactly what you’re paying for – including individual treatments, medications, services, external fees and VAT.

What it means for you: No more mystery totals. Just clear, transparent breakdowns so you can see where your money’s going.

More choice (and potential savings) on medication

Here’s a big one: vets must now actively tell you that you can request a written prescription and buy your cat’s medication elsewhere – often online, and often for less.

Written prescriptions must be provided promptly (either on the day or within 48 hours), and fees are now capped at £21 for the first medicine and £12.50 for each additional item.

What it means for you: More control over where you buy your cat’s meds – and the chance to save money, especially if your cat needs long-term treatment.

A clearer path if something goes wrong

Every practice will need a proper, written complaints process. They must acknowledge complaints within five working days and provide a full response within eight weeks – and take part in mediation if needed.

What it means for you: If something doesn’t feel right, you’ll know exactly how to raise it – and what kind of response to expect.

More transparency across the board

From out-of-hours care to cremation services, practices will need to be clearer about pricing, options and any additional costs.

There are also new rules to ensure fairer contracts between vet practices and service providers, helping keep the system more accountable overall.

What it means for you: Fewer hidden extras, clearer choices and more confidence in the care your cat receives.
