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 must have its veterinary-sector Orders in place by 23 September 2026. The Orders turn 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 of every remedy: implementation is staggered over the three to 12 months that follow the Orders being made, and smaller practices get longer than larger groups. The single most useful first move is to map which deadline applies 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.

The dates that matter

The CMA confirmed the headline timing when it concluded the investigation. On the implementation window, the CMA's announcement states: "Once the CMA Orders are made, nearly all remedies will be in place in the following three to 12 months." So the Orders are the starting gun, not the finish line.

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

• The Orders deadline is when the rules become binding, not when every change must be live. The CMA's own wording is that the Orders "will therefore be in place by 23 September 2026" — after which the staged implementation periods run.
• Smaller practices get extra time. The CMA states: "For most of the remedies, smaller veterinary businesses will have 3 months longer to implement the proposed changes than larger businesses." 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 expectation is the one your clients will compare you against soonest, even if your own formal deadline falls later.

Which remedies you are preparing for

The CMA's guidance for practices, "What veterinary businesses and vets need to do following the CMA's final vets report", sets out what each remedy requires. The package breaks into five workstreams a practice manager has to operationalise:

1. Published price lists — clear, standard price lists for a defined set of services, on your website and on display in the practice.
2. Written estimates — a written estimate where treatment is reasonably likely to cost £500 or more including VAT, 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.
3. Prescription transparency and fee caps — clients told about written prescriptions, with a cap on what you can charge for one. The amounts are covered in veterinary prescription fee caps under the CMA reforms.
4. Ownership disclosure — the identity of any larger group clearly identified on your website, signage, and communications.
5. Complaints and treatment information — a clear complaints process, 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 back from the Orders being in place by 23 September 2026, and treat the staged implementation as the time you have to get each workstream to "live," not "started."

Now to summer 2026: baseline and plan

• Run a gap analysis against the five workstreams. The CMA compliance self-assessment tool walks each requirement and flags what is missing.
• 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 structure, an estimate template, an ownership disclosure line for the website footer.

Around the Orders being made (late September 2026)

• Publish an initial price list, even if it is not perfect. The expectation for larger chains is that price lists appear first; matching that early protects you on the comparison your clients will actually make.
• Add the ownership disclosure to your website and signage. For an independent practice this is a single clear statement — and a genuine differentiator the reforms make visible.
• Brief the whole team on the written-estimate threshold and the prescription changes so the front desk and clinicians are consistent.

Through the staged implementation window

• Embed the written-estimate process into your clinical workflow so the £500 trigger is caught reliably, not remembered case by case.
• Implement the prescription fee caps in your billing system and update your price list to show the prescription fee.
• Build the complaints process into a documented procedure, with a log, and 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 when prices change, estimates need auditing for consistency, and ownership disclosure needs revisiting on any corporate change. Folding it 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:

1. Is a standard price list published on the website and on display in the practice?
2. Does every treatment reasonably likely to cost £500 or more (including VAT) get a written estimate?
3. Is there a process to issue an updated estimate when the likely cost rises by 20% or £500, whichever is lower?
4. Are prescription fees within the CMA caps and shown on the price list?
5. Is ownership clearly disclosed on the website, signage, and communications?
6. Is there a documented complaints process with a log?
7. 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 deadline reaches you.

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.
