CMA veterinary market guide

Questions to ask before agreeing to vet treatment

A practical checklist of questions to ask your vet before agreeing to treatment — covering costs, estimates, what is included, and how to understand your options without delaying urgent care.

Asking the right questions before agreeing to treatment can help you understand costs, options and what to expect — without delaying care that your pet needs urgently.

This guide is a practical checklist. It does not provide veterinary or medical advice, and it does not replace a conversation with your vet about what is right for your pet.

If your pet needs urgent care, seek it immediately. These questions are for planned or non-urgent treatment situations. Do not delay emergency treatment to ask about costs.

Source note: This guide is based on the CMA's veterinary market investigation final decision report and supporting materials. Vetfinder summarises findings for pet owners and does not provide veterinary, legal or financial advice.

Before agreeing to a treatment plan

When a vet proposes a course of treatment, you can ask:

About the treatment itself:
- What does this treatment involve, and why is it recommended?
- What are the alternatives, including doing nothing?
- What is the likely outcome with this treatment, and without it?
- How urgent is this — does it need to happen today, or is there time to think?

About costs:
- What is the expected total cost, including all likely extras?
- Can you provide a written estimate before I agree?
- What might change the final price — for example, if tests show something unexpected?
- How will you tell me if costs are going to go significantly above the estimate?

About what is included:
- Is the consultation fee included in this estimate, or separate?
- Are diagnostic tests (blood tests, X-rays) included, or charged on top?
- Is post-procedure pain relief or medication included?
- Is a follow-up appointment included, or will that be charged separately?

Before a routine or booked appointment

For a planned appointment such as a vaccination, neutering or dental check, you can ask in advance:

What is the current price for this service, including VAT?
What is included in that price, and what might be charged on top?
If my pet needs something extra during the appointment, how will you let me know before proceeding?
Is a consultation fee charged separately from the procedure cost?

About prescription medicines

If your vet is recommending a medicine you may need on an ongoing basis, you can ask:

Is a written prescription available for this medicine if I want to buy it elsewhere?
What is the written prescription fee?
How long will the prescription last, and when will my pet need a review before another one is issued?
Is the medicine urgently needed, or is there time to order it?

About the bill

After treatment, you can ask:

Can I have an itemised bill that lists the main charges?
Can you explain this line on the bill in plain English?
Does this match the estimate I was given — if not, why did the cost change?

The CMA's remedies include expectations around itemised billing for treatment. If something on your bill is unclear, asking for a plain-English explanation is entirely reasonable.

A note on tone

Most vets welcome clear questions. The aim is not to challenge clinical decisions, but to understand what is being recommended, what it costs, and what your options are.

Practical questions tend to work better than confrontational ones. For example:

"Before we go ahead — could you give me a rough idea of the likely total cost and what might change that?"

is more productive than assuming you are being overcharged.

If you have concerns about a bill after treatment, raise them with the practice directly in the first instance.

Comparing local practices

If you are registering a new pet or considering switching, WisePet shows available price information, ownership data, and review counts for local practices where we have data.

Frequently asked questions

Can I ask for a cost estimate before my vet starts treatment?

In most planned treatment situations, yes. For a routine or elective procedure, it is reasonable to ask what the expected cost is before you agree to go ahead. For emergency care, your vet's priority — and yours — should be your pet's welfare first. Once your pet is stable, it is reasonable to ask about likely further costs.

What should I ask if I do not understand the treatment being proposed?

Ask your vet to explain what the treatment involves in plain English, why it is recommended, what the alternatives are, and what the likely outcome is with and without the treatment. A good vet should welcome these questions. You can ask for time to think before agreeing to an expensive procedure.

Can I ask for a written estimate?

Yes. For planned treatment it is reasonable to ask for a written estimate that shows the expected cost before you agree. The CMA's remedies include expectations around written estimates for higher-cost treatment pathways (Final decision report — Part B). An estimate is not always a fixed price — if your pet's condition changes, costs can change — but it gives you a basis for understanding what to expect.

Can I ask for a prescription to buy medicine elsewhere?

In many situations you can ask whether a written prescription is appropriate for your pet and the medicine being prescribed. Your vet can advise on what is clinically suitable. A written prescription fee may apply. See our guide on vet prescription fees for more detail.

What should I do if the final bill is higher than the estimate?

Ask the practice to walk through the bill line by line. If costs changed during treatment, ask why. An itemised bill makes it easier to understand what you were charged for. If you have concerns, raise them with the practice in the first instance.

Is this guide medical or legal advice?

No. This guide suggests practical questions you can ask — it is not medical advice, legal advice or a substitute for speaking directly with your vet about your pet's care.
