Reform category
Provider size

  1. September 2026CMA Order expected / RCVS undertakings acceptedApplies to: CMA / RCVSRCVS / regulatorOut-of-hoursComplaints

    The CMA Order/undertakings are expected by 23 September 2026. Out-of-hours contract notice periods over 12 months become unenforceable immediately when the Order is in place.

    Why it matters: This is the legal starting point, not when all consumer-facing changes appear at once.

  2. 3 months after OrderLarge provider pricing and transparency dutiesApplies to: Large vet providers; OOH providersPricingCremationsOut-of-hours

    Large providers (15+ first-opinion practices) must comply with basic info, price lists, parasiticides, pet care plans, cremation and clinical-freedom policies. OOH providers must inform practices within three months.

    Why it matters: This is likely the first major point when large vet chains should become more comparable online.

    Expected requirements

    • Basic practice information
    • Standard price lists
    • Parasiticide price lists
    • Pet care plan information
    • Cremation information and communal cremation
    • Written clinical-freedom policies
  3. 6 months after OrderSmall provider duties and ownership transparencyApplies to: Small providers; all groups; all providers (complaints)PricingOwnershipPrescriptionsComplaintsCremations

    Small providers must meet many pricing and transparency duties. All vet groups must comply with ownership transparency. Large providers must comply with the written prescription fee cap. Complaint processes and mediation routes should be in place.

    Why it matters: Broader pricing transparency and clearer ownership information should become visible for more pet owners.

    Expected requirements

    • Small providers: basic info, price lists, parasiticides, pet care plans, cremation
    • All groups: ownership transparency
    • All providers: in-house complaints and mediation
    • Large providers: prescription fee cap (£21 / £12.50)
  4. 9 months after OrderEstimates, bills and medicines (large providers)Applies to: Large vet providers; RCVSTreatment choicesPrescriptionsRCVS / regulator

    RCVS should be ready to accept practice data for enhanced Find a Vet. Large providers must provide written estimates, itemised bills, and remaining prescription and medicines transparency requirements.

    Why it matters: Owners should receive clearer estimates and bills from larger providers, especially for higher-cost treatment.

  5. 12 months after OrderEstimates, bills and medicines (small providers)Applies to: Small vet providers; RCVSTreatment choicesPrescriptionsRCVS / regulator

    Businesses must provide key practice data to the RCVS. Small providers must comply with written estimates, itemised bills, and all prescription and medicines transparency requirements.

    Why it matters: Smaller practices should catch up on later-stage prescription, medicine and estimate requirements.

  6. 24 months after UndertakingFirst RCVS complaints insights reportApplies to: RCVSComplaintsRCVS / regulator

    The RCVS is expected to publish its first annual complaints insights report.

    Why it matters: This could give pet owners and researchers more visibility over complaints patterns in the sector.

Frequently asked questions

When do the CMA vet reforms start?

The CMA final report was published on 24 March 2026. Legally binding Orders/undertakings are expected by 23 September 2026, with most practical duties phased in from three to twelve months after the Order.

Will vets have to publish prices online?

Yes, for defined services, once the relevant deadlines apply. Larger providers are generally expected to comply around three months after the Order; smaller providers around six months after the Order.

What is the new prescription fee cap for vets?

The cap applies to the fee for issuing a written prescription: £21 for the first medicine in a consultation and £12.50 for each additional medicine in the same consultation, inclusive of VAT. It does not cap medicine or consultation fees.

Will I be able to see who owns my vet?

Vet groups are expected to display ownership information online, in premises, signage and communications. CMA guidance indicates this for groups around six months after the Order is in place.

Do vets have to give written estimates?

For treatment pathways reasonably likely to cost £500 or more including VAT, practices must provide a written estimate and update it if costs are likely to rise materially.

Will vet bills have to be itemised?

Yes. Practices are expected to provide itemised bills so owners can see how charges break down.

Do the CMA reforms apply to independent vets?

Many duties apply to veterinary businesses operating first-opinion practices, including independent practices. Deadlines can differ between larger and smaller providers.

Are vet prices being capped?

No. The CMA remedy caps written prescription fees, not consultation fees, medicine prices or overall treatment prices.

Will the CMA reforms make vet care cheaper?

The reforms focus on transparency and choice, not guaranteed lower prices. Owners may find it easier to compare options, but costs can still vary.

What should I do if I have a complaint about my vet?

Ask the practice about its complaints process first. If unresolved, mediation routes should become available under the reforms.
