The CMA's Vet Market Remedies, Explained in Plain English

The CMA published its final report on 24 March 2026 and made the Veterinary Services Market Investigation Order on 22 September 2026. The Order is binding, but different requirements begin on different dates. Here is the timetable for changes pet owners are likely to notice.

Price lists from December 2026 or March 2027

Practices must publish standard price lists for services they offer, including consultations, vaccinations, common surgery and diagnostic tests. The lists must show typical prices including VAT and be updated when charges change. Larger businesses must comply by December 2026; smaller ones by March 2027.

Until those lists appear, ask practices directly for prices. A listed typical price is a starting point: your pet's needs or complications can change the final charge.

Written prescriptions and the fee cap

You can already request a written prescription and buy suitable medication from a regulated retailer, subject to your vet's clinical assessment. The RCVS says a vet may currently charge a reasonable fee. The CMA Order will cap the fee at £21 for the first medicine and £12.50 for each additional medicine prescribed at the same consultation.

The fee cap starts in March 2027 for larger businesses and September 2027 for smaller ones. Requirements to actively tell owners about written prescriptions start in June 2027 for larger businesses and September 2027 for smaller ones. You can ask about the option now.

Written estimates and itemised bills

For recommended treatment reasonably likely to cost £500 or more including VAT, practices will have to give a written estimate before starting, except in emergencies. They will also have to give an itemised bill. These duties start in June 2027 for larger businesses and September 2027 for smaller ones. Ask for an estimate now if you need to plan or compare the cost.

Ownership and comparison data

Groups must identify their common ownership on websites, signs, at premises and in communications by March 2027. The RCVS must be ready to accept practice information, including prices, by June 2027; businesses must supply it by September 2027. Its enhanced Find a Vet service will share data with approved comparison sites.

What you can do now

Ask for a price or estimate before planned treatment, compare the total cost of repeat medication with a regulated online retailer, and ask who owns your practice. The published price lists and RCVS comparison data will make these checks easier as the new requirements take effect.
