CMA Veterinary Regulations: The Complete Practice Manager's Guide
By Brian Crocker · Published
Why a single overview matters now
Practices working through CMA compliance often approach it remedy by remedy — the pricing transparency checklist, the estimates procedure, the prescriptions communication. Each of those has its own page on gov.uk and its own operational detail. What's harder to find is a single map of how all six remedy areas fit together, what the sequencing looks like, and which of the six apply differently to independent practices versus group-owned ones.
This guide provides that map. It draws from the CMA's practice-facing guidance and the CMA's final report announcement.
The regulatory context
The Competition and Markets Authority conducted a market investigation into veterinary services for household pets that concluded in March 2026. The result was a package of mandatory remedies that veterinary businesses across the UK must implement. The CMA's own final report does not publish a single headline practice count, but the basis of its website review — "we checked 2,552 UK vet practice websites (58% of all UK vet websites, including both independent and LVG-owned FOPs)", reported in its Summary of final report — implies roughly 4,400 first-opinion practices (FOPs) in scope.
The CMA must make the Orders implementing these remedies by 23 September 2026 — that is the Order deadline. The CMA has stated that "once the CMA Orders are made, nearly all remedies will be in place in the following three to 12 months." Smaller independent practices will have longer than larger groups: "for most of the remedies, smaller veterinary businesses will have 3 months longer to implement the proposed changes than larger businesses."
The Orders have not yet been published as of the time of writing. Once they appear on legislation.gov.uk, this guide will be updated to reference them directly.
The six remedy areas
1. Ownership, prices, and services
Every veterinary business must publish clear price lists for a defined set of services. The list must appear on the practice website (if one exists) at most one click from the homepage, without scrolling. It must also be on prominently visible in-practice materials — posters or leaflets in the reception or waiting area.
Practices that are part of a corporate group must clearly and prominently identify the group on their website, premises, external signage and in communications. Independent practices state their independent status.
For the operational detail on price list format and display requirements, see CMA price list rules for vets.
For the ownership and corporate disclosure rules, see CMA ownership disclosure rules.
2. Information and policies on treatments
Practices must provide written estimates before proceeding with non-emergency treatment where the treatment is reasonably likely to cost £500 or more including VAT. If the total estimated cost is then reasonably likely to increase by 20% or £500 (whichever is lower), an updated estimate is required.
For the full estimate mechanics, see CMA written estimates: the £500 rule.
3. Prescribing veterinary medicines
Veterinary businesses must publicise to pet owners their ability to request a written prescription and that medicines may be cheaper elsewhere. Vets must orally offer a choice of written prescription in each consultation where medicine is prescribed. This does not mean the vet must say the medicine may be cheaper elsewhere in the consultation — the publicity obligation and the consultation offer are separate.
A fee cap applies to written prescriptions: the maximum fee is £21 for the primary prescription and £12.50 for each additional medicine prescribed within the same consultation.
For detail on the prescription fee caps and communication obligations, see veterinary prescription fee caps under the CMA reforms.
For the written prescription publicity rules in full, see CMA written prescription rules for UK vet practices.
4. Billing and invoicing
Practices must give pet owners itemised bills for treatment and other services. At minimum, an itemised bill must show: amounts for individual medicinal products; amounts for other goods and services; and fees for outside services plus any administration charge for arranging them.
For the detail on invoice minimum line items, see CMA itemised bills for vets.
5. Complaints and dispute resolution
Where a complaint cannot be resolved quickly, it becomes an actionable complaint. The practice must acknowledge it in writing within 5 working days and send a full letter of response within 8 weeks of the complaint becoming actionable. Firms of practice (FOPs) must publish their complaint process on their website and maintain a complaint log.
For the complaints process obligations in full, see CMA complaints process rules for UK vet practices.
6. Additional requirements
The CMA's package includes some obligations that apply to larger corporate groups and franchise operations rather than to individual independent practices. If your practice is part of a named group, your compliance obligations for the ownership disclosure and some of the transparency elements differ from those that apply to genuinely independent practices. The CMA guidance page sets these out by business type.
How the six areas fit together operationally
The remedies share a common structure: each creates an obligation to inform pet owners about something they could not easily find out before. The pricing list tells them what the practice charges before they arrive. The estimate tells them what their specific visit will cost before they agree to treatment. The prescription disclosure tells them they have the option to source medicines elsewhere. The itemised bill shows them what they were charged for after the fact. The complaints process gives them a route if something goes wrong.
Running across all of these is the ownership transparency element — pet owners should be able to see who owns the practice, since the CMA found that ownership concentration was affecting consumer decision-making.
For a practice working through implementation, the logical sequence is: price list first (website change, relatively straightforward); then estimate SOP (requires training as well as a written procedure); then prescription disclosure (staff training + website update); then invoicing configuration (may require PMS changes); then complaints procedure publication (writing the procedure and publishing it).
See the CMA compliance preparation timeline for a week-by-week planning guide.
What a practice should have in place
By the time the Orders set your implementation deadline, your practice needs:
- A published price list in the required format and locations (details)
- A written estimate procedure, staff-trained and SOP-documented (details)
- A website page or section publicising the written prescription right (details)
- A written prescription policy with fee cap applied (details)
- Billing configuration meeting the minimum line-item requirements (details)
- A written and published complaints process (details)
- Ownership disclosure implemented appropriately for your practice type (details)
The CMA compliance self-assessment tool lets you score your practice against these requirements and identify where the gaps are.
