CMA Ownership Disclosure Rules for UK Vet Practices

Who the ownership disclosure rule applies to

Order made; this duty applies from 22 March 2027, for every size of business. The CMA made the Veterinary Services Market Investigation Order 2026 on 22 September 2026, and it came into force the next day. Under Article 3 of the Order, ownership information has a compliance date of 22 March 2027 for larger and smaller businesses alike, and practices must comply from the next working day after that date.

Article 5 of the CMA Order requires veterinary businesses that form part of a "Group or Network" to show who is behind them. What they must show is the name of the "Main Entity" (the business in overall control), or the trading name it uses for the group, plus any common group logo or branding.

The point of the remedy is that pet owners often cannot tell whether the practice down the road is independently owned or one of several sites under a single corporate group. The Order's definition of a group is wider than many practices expect, so it is worth checking which side of the line you are on before deciding the rule does not apply to you.

What "the group" means for your practice

The Order defines a "Group or Network" to include "a person or entity providing Veterinary Services by carrying on or operating more than one FOP or OOH Centre", where there is a Main Entity over those sites. It also covers arrangements where more than one business is involved under a common Main Entity. That has three practical readings:

• If your practice is part of a corporate group — a corporate owner, or a brand that sits above the individual practice — the group's name is what must be shown. A site that trades under a local name but is owned by a larger group has to make the group ownership visible, not just the local trading name.
• If you are an independent with more than one site, that definition catches you, even though no corporate parent sits above you, because its first limb covers a single business operating more than one FOP or out-of-hours centre. The business that runs the sites is the Main Entity, and its name or group trading name must be shown at each site and on each site's website. If every branch already trades under the same name, much of this will already be true. Check it against the detailed rules below rather than assuming.
• If you are a genuinely standalone single-site practice — no parent, no other sites, and no franchise, joint-venture or shared-brand arrangement — Article 5 does not require you to disclose anything. Be careful with that last condition. The Order's test for a group also counts influence: a brand identity you are required or encouraged to adopt, veto or step-in rights, the right to approve your business plans, or guarantees of your finance. So a single-site franchisee or joint-venture practice can be part of a group even with no other sites of its own. Stating plainly that you are independently owned is still worth doing (see below), but it is a choice, not a CMA duty.

If you are unsure which side of the line your practice sits on — for example after a recent acquisition, or where a holding company sits above the practice — take advice. The Order looks at ownership, control and influence, including shared branding, veto rights and financial guarantees, not just who holds the shares.

Where the disclosure has to appear

The Order is specific that this is not a single website footnote. Ownership information must be shown in a "Clear and Prominent" way in each of these places:

• Websites — the group's website and the website of each practice in it (Article 5(3)). The Main Entity or group trading name must also appear on each homepage, including the top banner where there is one, and in the metadata of every page (Article 5(4)).
• Search and maps — in paid-for and organic search results, and in online map listings for premises clients visit. You are not in breach where you cannot control those results yourself, as long as you have made all reasonable requests to whoever does (Article 5(5)).
• At the premises — including storefront signage (Article 5(6)).
• In communications — the material the practice sends to clients, including referrals to other sites in the same group (Article 5(7)).

The group name must also be "at least equal in prominence to any other names published or displayed with it", judged on size, legibility, position, colour and typography (Article 5(8)). A group name in small print beneath a large local practice name does not meet that test. It must also be clear that the name is the owner's name, not a description of the services.

Turning the obligation into a one-time setup

For most practices this is a setup task rather than an ongoing burden, and it is one of the cheaper remedies to close. A reliable approach:

1. Decide whether Article 5 applies to you. Standalone single site (no parent, franchise, joint-venture or shared-brand arrangement): no duty. More than one site, or part of any group: it applies.
2. Decide the exact name to show. For a group, that is the Main Entity's name or the trading name it uses for the group. For a single-site independent choosing to say so, a single clear line ("[Practice name] is an independently owned veterinary practice") is enough.
3. Place it everywhere the Order lists. The homepage banner, page metadata, premises signage, client communications, and your search and map listings.
4. Record where it lives. Keep a short note of every place the disclosure appears, so that if ownership changes you know what to update.
5. Fold the review into your governance cycle. Ownership disclosure only needs revisiting on a corporate change, but a periodic check inside your wider clinical governance framework stops it drifting out of date silently.

When this starts to apply to your practice

Ownership disclosure is unusual in this package: it has no split between larger and smaller businesses. The Order's Article 3 table gives it a compliance date of 22 March 2027 for everyone. That is the same date on which smaller practices have to meet the price-list rules, and earlier than the estimates, bills and prescription remedies.

The practical consequence is that a small practice does not get its usual extra three months here. If Article 5 applies to you, this one belongs in the first wave rather than the last.

Why independents should not under-play this

It is tempting to treat ownership disclosure as a rule aimed at the large groups and therefore irrelevant to an independent practice. That misreads the opportunity. The reforms exist partly because pet owners value knowing whether their vet is independent. From March 2027 every group-owned practice will have to show its owner prominently. An independent practice that states its own ownership clearly is surfacing a differentiator the reforms have just made visible to clients.

How ownership disclosure fits the wider CMA package

Ownership disclosure is one of several remedies a practice has to operationalise together. It sits alongside published price lists, written estimates, prescription transparency and fee caps, and a documented complaints process. Sequencing them is what the CMA preparation timeline is for, and the CMA compliance self-assessment tool flags which remedies your practice still has open. Treated as one workstream inside your existing governance cycle — rather than a scramble per remedy — the package is manageable for an independent practice.

Reviewed 26 October 2026. The CMA made the Veterinary Services Market Investigation Order 2026 on 22 September 2026 and it came into force on 23 September 2026. The definition of a group, the display rules and the compliance date above are taken from the Order itself, not from the draft consulted on in July and August 2026. This is general compliance information, not legal advice. Verify the current position against the Order and its Explanatory Note and the CMA's guide for small veterinary businesses (14 or fewer practices) or large ones (15 or more), and consult your defence body for practice-specific advice.
