Vet Prescription Price Cap UK Explained (2026)

A new vet prescription price cap is being introduced in the UK following a three-year investigation by the Competition and Markets Authority (CMA). Under the new rules, prescription fees are expected to be capped at around £21 for the first item and £12.50 for additional medications on the same prescription.

The changes aim to reduce costs, improve pricing transparency, and give pet owners more control over how they access medication. In this guide, you will learn what the vet prescription price cap means, why it has been introduced, and how it affects the cost of treatment for your dog or cat.

What Is the Vet Prescription Price Cap?

The vet prescription price cap is a new rule introduced by the Competition and Markets Authority (CMA) to limit how much veterinary practices can charge for written prescriptions in the UK. Under this cap, prescription fees are expected to be set at around £21 for the first item and £12.50 for additional medications on the same prescription.

This replaces a system where fees could vary widely between practices, with some charging £30 or more for a single prescription. The cap is designed to make pricing more consistent and remove a key barrier that has prevented pet owners from comparing medication costs and purchasing from alternative pharmacies.

Why the CMA Introduced the Cap

The Competition and Markets Authority (CMA) introduced the vet prescription price cap after identifying widespread issues with pricing and transparency across the UK veterinary sector. Its investigation found that prescription fees varied significantly between practices, with some pet owners paying much more than necessary for the same medication.

The CMA also found that many clients were not clearly informed they could request a prescription and purchase medication from a licensed online pharmacy at a lower cost. Between 2016 and 2023, average veterinary service prices increased by 63%, raising concerns about affordability and competition.

The price cap is intended to reduce excessive variation in fees, improve transparency, and make it easier for pet owners to compare costs and access more affordable treatment options. These issues are part of a wider pattern across the sector, as explained in our guide on why vet bills are so expensive in the UK.

How Much Will You Actually Pay Now?

Under the new rules, vet prescription fees are expected to be capped at around £21 for the first item and £12.50 for additional medications on the same prescription, creating a more consistent pricing structure across the UK. Before the cap, fees typically ranged from £10 to £35, with some practices charging more.

This variation often made it difficult for pet owners to compare costs or justify buying medication elsewhere. In practical terms, the cap reduces the maximum cost of a prescription and makes it more worthwhile to request one and purchase medication from a licensed pharmacy.

For example, a prescription that previously cost £30 may now be closer to £21. When combined with lower online medication prices, this can lead to significant savings over time.

What Vets Must Do Under the New Rules

The CMA reforms introduce new requirements for veterinary practices to improve transparency and help pet owners make informed decisions about treatment costs. Under the new rules, vets will need to provide clear pricing information and make it easier for clients to understand their options before agreeing to treatment.

In practice, this means veterinary practices will be required to:

• Publish clear, itemised price lists for consultations, treatments, and prescriptions
• Inform clients that they can request a prescription and purchase medication from another pharmacy
• Provide written estimates for treatments over £500, including a clear breakdown of costs
• Disclose whether the practice is independently owned or part of a corporate group

These changes are designed to improve transparency across the sector and ensure pet owners have greater control over how they access and pay for treatment.

Can You Still Buy Medication Online?

Yes, you can still buy pet medication online. The new rules do not restrict this and are designed to make it easier for pet owners to compare prices and access alternative options.

You have the legal right to request a written prescription from your vet and use it to purchase medication from a licensed UK pharmacy. Under the updated guidance, veterinary practices will also be required to make this option clear, removing a key barrier that has previously limited price comparison.

In many cases, medication purchased online can cost 30% to 70% less than buying directly from a clinic, even after including the prescription fee.

How This Affects You as a Pet Owner

The introduction of a vet prescription price cap is expected to make treatment costs more predictable and easier to understand. With clearer pricing and lower prescription fees, it becomes more practical to compare options and make informed decisions.

For many pet owners, this means greater control over how medication is purchased. You can request a prescription, compare prices across licensed pharmacies, and avoid paying significantly more than necessary. The changes also reduce the risk of unexpected costs, particularly for pets that require long-term medication.

Even small savings on prescription fees can add up over time when combined with lower online medication prices. Alongside these reforms, there are still practical steps you can take to manage costs, as explained in our guide on how to reduce vet bills.

When Will the Changes Take Effect?

The vet prescription price cap has been confirmed by the Competition and Markets Authority (CMA), with changes being introduced in phases across the UK veterinary sector.

The reforms will not happen all at once. Instead, they will be rolled out gradually between late 2026 and 2027 to give practices time to adjust.

While exact timing may vary slightly between practices, the direction is clear. Pricing will become more transparent, and pet owners will have better control over how they manage treatment costs.
