Vet bills beginning to bite – What to watch out for, and how you can save

5 min read

You take your pet to the vet expecting a quick check-up and suddenly the bill is far higher than you expected. A consultation turns into tests, medication, maybe a follow-up appointment, and before you know it the total is into the hundreds.

Vet bills have been rising across the UK, and it’s become such a concern that regulators are now investigating the industry. Veterinary service prices increased by about 63% between 2016 and 2023, far faster than many other services. Rising costs and concerns about pricing transparency have led the Competition and Markets Authority (CMA) to open a major investigation into how veterinary practices charge pet owners.

If you have a pet, understanding how vet pricing works and what to ask before agreeing to treatment can help you avoid unexpected costs.

The vet industry is under investigation

Your pet is on the exam table and the vet starts recommending tests or treatment. In that moment, you’re focused on helping your pet, not stopping to ask detailed questions about the price.

Regulators stepped in after finding that that many pet owners struggle to compare vet prices or even know what different practices charge. Another issue is ownership, as a large number of veterinary clinics are now owned by corporate groups, which can make the market harder to navigate.

The CMA is considering changes that could reshape how vets operate. These include requiring practices to publish clearer price lists, provide more detailed itemised bills, and explain whether they are part of a larger corporate group, making it easier to compare costs and understand what you’re paying for.

Watch out for medication mark-ups

One of the biggest hidden costs in vet bills is medication. If your pet needs treatment, the vet will often offer to supply the medicine directly from the clinic. That’s convenient, but it isn’t always the cheapest option.

You have the right to ask your vet for a written prescription instead. Once you have that prescription, you can buy the medication from a licensed online pharmacy, where prices are often much lower.

The CMA investigation found that some pet owners are paying significantly more for medicines at vet practices than they would online. Because of this, regulators are considering limits on prescription fees to make it easier for pet owners to shop around.

Ask for an estimate before treatment starts

When your pet is unwell, it’s easy to say yes to every test or procedure your vet suggests. But you still have the right to understand what the treatment will cost. Before agreeing to diagnostics or treatment, ask the vet for a clear estimate. That estimate should include consultation fees, tests, medication and any follow-up appointments.

You can also ask whether every recommended test is necessary immediately. Vets often suggest what’s known as a “gold standard” diagnostic approach involving several tests. Sometimes there are alternative options depending on your pet’s condition. If the treatment could cost several hundred pounds or more, ask for the estimate in writing. Knowing the likely cost helps you make informed decisions.

Pet insurance can protect you from big bills

With vet costs rising, pet insurance can make a big difference if your pet needs serious treatment. Insurance policies typically cover major expenses such as surgery, diagnostics, hospital stays and specialist referrals. Without insurance, those treatments can quickly cost thousands.

If you’re considering pet insurance, it’s usually best to take it out while your pet is young and healthy. Once a medical condition has been diagnosed, insurers usually treat it as a pre-existing condition, which means it won’t be covered. Insurance won’t remove every cost, you’ll still pay an excess, but it can prevent a medical emergency from becoming a financial nightmare.

Small steps that can keep vet costs down

You can also reduce the chances of expensive vet bills by focusing on preventative care. Keep your pet’s vaccinations up to date and stay on top of flea and worm treatments. These small routine steps can help prevent bigger health problems later.

If your vet recommends an expensive treatment plan, you can also ask for a second opinion from another practice. Most vets understand that pet owners want to make informed decisions, especially when large costs are involved. Comparing medication prices, asking about preventative care plans and requesting clear estimates all help you stay in control of the costs.

If a vet bill doesn’t seem right

If something about your vet bill doesn’t make sense, start by asking the practice for a detailed breakdown of the charges. Most clinics are happy to explain the costs once you ask. Many disputes come down to misunderstandings about tests, medication or consultation fees.

If the practice doesn’t resolve the issue, it should have a formal complaints procedure. You can also escalate disputes through mediation services such as the Veterinary Client Mediation Service.

Vet care is becoming more advanced and more expensive. That means you need to stay a little more proactive when it comes to costs. Before you agree to treatment, ask for an estimate. If medication is involved, check whether buying it from a pharmacy could be cheaper. And if you don’t already have pet insurance, think about whether it could protect you from larger bills down the line.

You want the best care for your pet, but when you ask the right questions and understand your options, with the right information and protection, you can make those decisions with confidence without being caught off guard by the bill. 🐾
