How to Prepare for the CMA Vet Orders: A Practice Manager's Timeline

When the CMA Orders take effect, and what to do first

The Competition and Markets Authority made the Veterinary Services Market Investigation Order 2026 on 22 September 2026, and accepted the RCVS's Undertakings the same day. The Order came into force the next day. It turns the CMA's Final Report remedies into legally binding requirements — published price lists, written estimates, prescription fee caps, ownership disclosure, and complaints handling. You do not have to be compliant on day one with every remedy. The Order sets its own compliance date for each one, spread over the following three to 12 months, and smaller practices get longer than larger groups. The single most useful first move is to find which dates apply to your practice, because that decides what you can sequence and what you cannot.

This guide sets out the timeline as it actually works — not a single cliff-edge date — and turns it into a month-by-month preparation plan a practice manager can run. For what each duty requires, rather than when, start with the CMA veterinary regulations practice guide.

The dates that matter

The CMA set the shape of the timing when it concluded the investigation. Its announcement said: "Once the CMA Orders are made, nearly all remedies will be in place in the following three to 12 months." So the Order is the starting gun, not the finish line.

Two things follow from that, and they are the reason a generic "September 2026 deadline" framing was always misleading:

The Order date is when the rules became binding, not when every change must be live. In March the CMA said its Orders "will therefore be in place by 23 September 2026". It made the substantive Order on 22 September 2026, a day inside that deadline, and the staged compliance dates now run from there.
Smaller practices get extra time. The CMA said: "For most of the remedies, smaller veterinary businesses will have 3 months longer to implement the proposed changes than larger businesses." The made Order bears that out. If you run an independent practice, that breathing room is real, but it is for implementation, not for ignoring the requirements until later.

Pet owners will start seeing the most visible changes at larger chains first. The CMA notes that customers of a practice in a larger group "can expect to see changes before Christmas – including standard price lists". For an independent practice, the practical read is that the published price list is the one your clients will compare you against soonest, even though your own compliance date is later.

Every deadline, by remedy and practice size

"Three to 12 months" is the headline, but it is not what you plan against — each remedy has its own date, and the spread between them is nine months. Article 3 of the Order lists a compliance date per remedy. Businesses must comply "from the next Working Day after the dates stipulated in the following table".

First, which column you are in. The Order defines a "Small Veterinary Business" as one "with fewer than 15 FOPs and/or OOH Centres" — first-opinion practices and out-of-hours centres counted together. Almost every independent practice is in the "smaller" column.

Remedy (Order article)	Larger (15+ FOPs and/or OOH centres)	Smaller (under 15)
Out-of-hours contract notice periods (Art 19(4)-(5)(b))	22 Sep 2026 — already live	22 Sep 2026 — already live
Out-of-hours providers write to client practices (Art 19(5)(c))	22 Dec 2026	22 Dec 2026
Practice information, price list, parasiticide price list, pet care plans (Arts 6-9)	22 Dec 2026	22 Mar 2027
Clinical freedom policies (Art 13)	22 Dec 2026	22 Mar 2027
Cremation options and prices (Art 20)	22 Dec 2026	22 Mar 2027
Ownership information (Art 5)	22 Mar 2027	22 Mar 2027
Complaint process, complaint log, mediation (Arts 21-23)	22 Mar 2027	22 Mar 2027
Prescription fee caps (Art 18)	22 Mar 2027	22 Sep 2027
Written estimates (Art 11)	22 Jun 2027	22 Sep 2027
Itemised bills (Art 12)	22 Jun 2027	22 Sep 2027
Written-prescription information, provision, flyer, own-brand medicines (Arts 14-17)	22 Jun 2027	22 Sep 2027
Supplying practice information to the RCVS for Find a Vet (Art 10)	22 Sep 2027, or 3 months after the RCVS is ready, whichever is later	Same

Four things in that table are worth knowing before you plan around it:

One change is already live, and it helps you. Since the Order came into force, an out-of-hours provider cannot hold a practice to more than 12 months' notice or charge a termination payment for leaving on proper notice (Article 19). If you outsource out-of-hours cover on a longer contract, you can now give no more than 12 months' notice to leave. If your contract had a notice term over 12 months or a fee for leaving on proper notice, your provider must write to you by the next working day after 22 December 2026 to confirm the position.
A smaller practice has one more 2026 date to note: an information return. Under Article 26(1), every business operating a first-opinion practice, out-of-hours centre, crematorium or referral centre when the Order came into force must send the RCVS, in writing, its name, trading name, head office address, a named contact for compliance, and the name and addresses of each site it operates. The deadline is "30 November 2026, to the extent that it has not already done so in accordance with Article 5 of the Funding Order", so if you already gave the RCVS these details under the CMA's separate Veterinary Services Market Investigation (Funding) Order 2026, there is nothing more to send. The CMA's guide for small businesses says the details go "to the RCVS via email" and gives the address to use. Apart from that, an independent practice's first Article 3 compliance date is 22 March 2027, and its last main one is 22 September 2027.
Two remedies give smaller practices no extra time. Ownership information and the complaints process share one date for businesses of every size. If you are sequencing the work, those belong in the first wave.
The prescription fee cap splits unusually wide. Larger businesses must comply from March 2027 and smaller ones from September 2027 — a six-month gap, the biggest in the package. Expect capped fees to be advertised by the chains well before your own deadline.

The RCVS data return (Article 10) is the one date that can still move. It is 22 September 2027 or three months after the RCVS has set up its Find a Vet data-collection form, whichever is later. The RCVS has undertaken to do that within nine months of 22 September 2026.

Which remedies you are preparing for

The CMA publishes two plain-English guides to the Order, one for small veterinary businesses (14 or fewer practices) and one for large ones (15 or more). They describe each remedy and its date, and the Order sets the binding detail. The package breaks into five workstreams a practice manager has to operationalise:

Published price lists — standard price lists for the 36 items in the Order's Schedule 1, on your website and at the practice. The detail is in the CMA price list rules.
Written estimates — a written estimate where treatment is reasonably likely to cost £500 or more including VAT and more than £100 of it is still to come, with an update if the likely cost rises by 20% or £500 (whichever is lower). The detail is in the CMA written estimate rules for vets.
Prescription transparency and fee caps — clients told about written prescriptions through standard materials, with a cap of £21.40 for the first medicine and £12.70 for each additional one. The amounts are covered in veterinary prescription fee caps under the CMA reforms.
Ownership disclosure — the group's name shown prominently on websites, signage and communications, which the Order applies to any business running more than one site. See CMA ownership disclosure rules.
Complaints and treatment information — a published complaints process with an approved mediation provider, treatment options with costs, and out-of-hours arrangements disclosed.

None of these is technically hard in isolation. The difficulty is doing all five across a practice that is already running a dozen other non-clinical compliance streams — and keeping the evidence current after the initial push.

A month-by-month preparation plan

Work forward from the Order rather than back from a single date, and treat each remedy's compliance date as the point by which that workstream must be "live," not "started." The sequence below follows the order of the dates in the table above.

Now, to December 2026: baseline and plan

Nothing is enforceable against a smaller practice's own services in this period, which makes it the cheapest time to do the thinking.

Run a gap analysis against the five workstreams. The CMA compliance self-assessment tool walks each requirement and flags what is missing.
Check your out-of-hours contract. If its notice period is over 12 months, the Order has already capped it.
Confirm the RCVS has your business and site contact details. If you did not already supply them under the separate Funding Order, Article 26 requires them in writing by 30 November 2026.
Decide who owns each workstream. Pricing and ownership disclosure usually sit with the practice manager; estimates and prescriptions involve the clinical team.
Draft the documents you control now — a price list in the Schedule 1 format, an estimate template, an ownership disclosure line for the website.
Watch what the chains publish. Their price lists are due from 23 December 2026, which shows you what "compliant" looks like in practice a full quarter before your own deadline.

To 22 March 2027: the first wave of real deadlines

This is where an independent practice's obligations actually begin — several remedies at once.

Publish the price list, on the website no more than one click from the homepage on a page labelled with "prices" or "fees", and at the practice in reception.
Publish the related information — basic practice information, the parasiticide price list, pet care plan details, and cremation options and prices.
Put clinical freedom policies in place, so vets can give independent advice and a range of options with costs.
Show ownership information if you run more than one site or belong to a group. For a standalone single-site practice (no parent, franchise, joint-venture or shared-brand arrangement), stating independence is optional but worth doing.
Publish the complaints process, with the timeframes stated, a named approved mediation provider, and a complaint log behind it.

To 22 September 2027: the clinical and billing wave

The remaining remedies are the ones that change behaviour and systems rather than web pages, which is why they carry the longest window — and why they need the most lead time.

Embed the written-estimate process into clinical workflow so the £500 trigger is caught reliably and the estimate goes out by the end of the next working day.
Configure the practice management system for itemised bills, allowing for the vendor's release cycle rather than your own.
Apply the prescription fee caps in billing and show the fees on the price list.
Place the standard written-prescription notice, messages, invoice footer and flyer where the Order requires, and brief clinicians on the per-consultation oral offer.
Connect the whole package to your clinical governance framework so the audit cycle keeps it current.

Steady state

CMA compliance is not a project that finishes. Price lists need updating before prices change, estimates need auditing for consistency, and ownership disclosure needs revisiting on any corporate change. From April 2028 the £500 threshold and the prescription fee caps are uprated each year for inflation, with the CMA publishing the new figures by 14 February. Folding all of this into an existing quarterly audit cycle is what stops it drifting back to non-compliant after the launch effort fades.

A readiness checklist

Use this as a fortnightly status check in the run-up:

Is a standard price list published on the website and on display in the practice?
Does every treatment reasonably likely to cost £500 or more (including VAT) get a written estimate by the end of the next working day?
Is there a process to issue an updated estimate when the likely cost rises by 20% or £500, whichever is lower?
Are prescription fees within the CMA caps and shown on the price list?
Is ownership clearly disclosed on the website, signage, and communications (if you run more than one site or belong to a group)?
Is there a documented complaints process with a log and a named mediation provider?
Does your governance cycle own the review schedule for all of the above?

A "no" against any of these is a gap to assign and close before the relevant date reaches you — and the dates differ per item, so check each one against the table above rather than working to a single date.

How this fits your wider compliance picture

The CMA reforms add a new stream on top of the RCVS Practice Standards Scheme, health and safety, COSHH, controlled drugs, and the rest of the non-clinical compliance workload. Practices that already run a governance framework with a real audit cycle will absorb CMA compliance into it. Practices without one will find the CMA the reason they finally build it.

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. Every date in the table above is taken from Article 3 of the Order itself, and businesses must comply from the next working day after each date. The CMA's guides for small and large veterinary businesses, published on 13 October 2026, give the same dates. The separate Veterinary Services Market Investigation (Funding) Order 2026, made on 20 August 2026, deals with RCVS funding rather than these remedies. This is general compliance information, not legal advice. Verify the current position against the Order and its Explanatory Note and the CMA's veterinary services case page, and consult your defence body for practice-specific advice.
