Linnaeus

What they own

• Local trading names retained at most practices
• Davies Veterinary Specialists (referral)
• Anderson Moores (referral)
• Cave Veterinary Specialists (referral)

Many practices retain their original local trading name even after acquisition. The parent group is not always obvious from the practice website or signage. From 23 September 2026 ownership disclosure becomes mandatory during the consult.

What the CMA found

Linnaeus is Mars Petcare's UK veterinary services arm and operates a substantial referral specialty footprint. The CMA's findings on disclosure, dispensing margins and written-prescription access apply to Linnaeus as one of the six named large groups. Mars's wider pet-care ownership — including pet food brands and Banfield in the US — was also flagged in submissions to the investigation.

The full Final Report and accompanying Order are public at gov.uk/cma-cases.

What changes from 23 September 2026

• Disclose corporate ownership at the start of consultations.
• Offer written prescriptions on request; £21 + £12.50 fee structure.
• Display top-10 most-sold products price list.
• Disclose during the consult that medication is often cheaper online.
• Provide written estimates above £500.
• Publish a standardised complaints process.

How to check if your practice is owned by Linnaeus

1. Look at the corporate footer on the practice website. Many practices include a line like "Linnaeus Limited" or "part of Linnaeus".
2. Check the practice on the RCVS Find a Vet register. The accredited practice listing includes ownership details.
3. Ask at reception. From 23 September 2026 the practice must disclose corporate ownership during the consultation regardless.

Frequently asked questions

My referral hospital is a Linnaeus brand — does the Order apply?

Yes. The Order applies to all UK veterinary practices owned by the six named groups. Referral hospitals are typically higher-cost environments and the £500 written-estimate threshold is particularly relevant.

Is Linnaeus a different group from Banfield?

Banfield is Mars Petcare's US veterinary brand. Linnaeus is the UK group. Both share ultimate parent ownership.

Does owning pet food brands create a conflict?

Mars Petcare also owns Royal Canin, Eukanuba and others. The CMA raised related concerns about diet recommendations in clinic, though the Order's primary focus is medication pricing and disclosure.
