Why Are Vet Bills So Expensive in the UK? What the CMA Investigation Means for Dog Owners

If you’ve taken your dog to the vet recently and nearly fell over when they told you the bill, you’re not imagining things. Vet prices in the UK have risen by 63% between 2016 and 2023 – massively outpacing inflation – and the government has finally stepped in. The Competition and Markets Authority (CMA) concluded a major investigation into the veterinary sector in March 2026, and the findings confirmed what most dog owners already suspected: the system is broken, prices are too high, and transparency is terrible.

Here’s what the investigation found, what’s changing, and what you can do right now to keep your vet bills as low as possible.

Why Have Vet Bills Gone Up So Much?

The CMA investigation uncovered some pretty damning stuff. The headline figure is that 63% price increase, but the reasons behind it are what really matter.

Over 60% of UK vet practices are now owned by just six large corporate groups – CVS, IVC, Pets at Home, VetPartners, and two others. The CMA found that four of these groups made profits that “materially exceeded the cost of capital,” which is regulator-speak for “they’re making more money than they should be.”

The problem is that most people don’t realise their local, friendly-looking vet practice is actually owned by a massive corporate chain. The branding stays the same, the staff stay the same, but the prices creep up and the margins go to shareholders rather than staying in the practice. The CMA specifically flagged this lack of transparency as a major issue.

On top of corporate consolidation, there’s a genuine shortage of vets in the UK, which pushes wages and overheads higher. Equipment has become more advanced (and expensive). Drug costs have gone up. All of that gets passed straight on to you at the till.

What Did the CMA Actually Find?

The investigation ran from May 2024 to March 2026 and received over 56,000 responses – including 45,000 from the public. The key findings were:

Vet prices rose 63% between 2016 and 2023 – well above the rate of inflation over the same period.

Pet owners aren’t given the information they need to compare prices between practices or make informed choices about treatment options. Most people have no idea what a procedure should cost until they’re already committed.

The regulatory system is “outdated and wholly unfit for purpose” – it regulates individual vets but not the businesses they work for, meaning the corporate groups operating most UK practices face almost no oversight of pricing.

Vets aren’t routinely telling pet owners they can buy prescription medications elsewhere – meaning most people pay inflated in-practice prices for drugs that are available much cheaper from licensed online pharmacies.

What’s Changing After the CMA Investigation?

The CMA proposed 21 reforms to the veterinary sector, with implementation scheduled from September 2026. The big ones for dog owners are:

A £16 cap on prescription fees. Currently, vets can charge whatever they like to write a prescription so you can buy medication elsewhere. Some charge £20 to £30 just for the prescription, which wipes out the savings of buying online. The new £16 cap makes it financially worthwhile to shop around for medication.

Mandatory written estimates for treatments over £500. Vets will be required to provide a written cost estimate before starting any treatment that’s reasonably expected to cost £500 or more. No more nasty surprises at the end.

Clearer ownership information. Practices will have to be upfront about who owns them, so you’ll know whether you’re at an independent practice or a corporate-owned one.

These are positive steps, but they won’t kick in until late 2026 at the earliest. In the meantime, you need to be proactive about keeping your costs down.

How Much Do Common Vet Procedures Actually Cost Right Now?

The average vet consultation in the UK now costs around £58 to £62, according to recent price surveys, up 8% from last year alone. But the consultation fee is just the starting point. Here’s what common procedures are costing UK dog owners in 2026:

Standard consultation: £40 to £75 (up to £81 in some areas)

Blood tests: £100 to £250

X-ray: £200 to £400

Ultrasound: £250 to £500

Dental clean under anaesthetic: £250 to £500

Lump removal and biopsy: £500 to £1,500

Foreign body removal surgery: £1,500 to £4,000

Cruciate ligament repair: £3,000 to £7,000

MRI scan: £1,500 to £3,000

Emergency out-of-hours consultation: £200 to £400 (before treatment)

That cruciate ligament figure is the one that shocks people the most. It’s one of the most common injuries in dogs, and it’s not unusual for both legs to go. Potentially £14,000 for one condition.

Is Pet Insurance Worth It Now That Vet Bills Are So High?

If there was ever a time to have pet insurance, it’s now. At 63% price inflation over seven years, vet bills are only going in one direction. A single surgery can wipe out months of careful saving.

The maths is pretty straightforward. A lifetime pet insurance policy costs £20 to £60 a month for a young, healthy dog. That’s £240 to £720 a year. One cruciate ligament repair costs £3,000 to £7,000. One course of cancer treatment costs £5,000-£10,000+. You only need one significant claim in your dog’s lifetime, and the insurance has paid for itself many times over.

The important bit is getting a lifetime policy – the type that resets its annual limit each year when you renew. That way, if your dog develops arthritis, allergies, diabetes, or any other chronic condition, you’re covered every year, not just for the first twelve months. Time-limited policies cut you off after a year per condition, which is exactly when the ongoing costs really start adding up.

It’s worth taking the time to compare lifetime dog insurance policies from providers like Perfect Pet to find cover that fits what you can afford without leaving gaps in protection. The golden rule is to insure your dog while it is young and healthy; once a condition has been diagnosed, every insurer will exclude it as pre-existing.

How Can You Save Money on Vet Bills Right Now?

While we wait for the CMA reforms to kick in, here’s what you can do today to keep costs down:

Ask for a prescription and buy medication online. Your vet is legally required to give you a prescription if you ask for one. Licensed online pharmacies like VetUK, Pet Drugs Online, and Animed Direct sell the same medication at 30–50% less than most vet practices charge. Yes, you’ll pay a prescription fee (soon to be capped at £16), but the saving on the actual medication more than covers it, especially for ongoing treatments.

Shop around for vet practices. The CMA found that most pet owners don’t compare prices between practices. Consultation fees vary from £40 to £81 depending on location and ownership. Call a few local practices, ask for their consultation fee and vaccination prices, and you might be surprised at the difference. Independent practices are often (though not always) cheaper than corporate-owned ones.

Don’t ignore small problems. A skin irritation that costs £50 to sort out now becomes a chronic allergy costing £1,000+ a year if you leave it. A slight limp that needs anti-inflammatories (£100) can become a cruciate ligament rupture needing surgery (£5,000+) if you wait. Catching things early is one of the simplest ways to avoid massive bills.

Keep your dog at a healthy weight. Overweight dogs are significantly more likely to develop joint problems, diabetes, and heart disease. All of those are expensive to treat. Portion control and daily walks cost nothing and could save you thousands over your dog’s lifetime.

Brush your dog’s teeth. I know, it sounds ridiculous. But dental disease is one of the most common conditions in dogs over three, and a professional dental clean costs £250 to £500. Extractions push that to £800+. A £5 dog toothbrush and a tube of enzymatic toothpaste, used a few times a week, dramatically reduces the risk. It’s one of the best returns on investment in dog ownership.

Can You Get Help with Vet Bills If You’re on a Low Income?

If money is tight, there are genuine safety nets. The Blue Cross offers affordable veterinary treatment at its animal hospitals across the UK, with fees set well below the average. The PDSA provides free veterinary care to pets whose owners receive certain means-tested benefits. The RSPCA and Dogs Trust also offer support in some areas.

Some vet practices offer payment plans or interest-free credit for larger bills. It’s always worth asking before you commit to treatment, most vets would rather work out a payment arrangement than see a dog go untreated.

So What Should You Actually Do?

Vet bills have gone up 63% in seven years, and the CMA investigation confirmed what every dog owner already knew: the system hasn’t been working in our favour. Reforms are coming in late 2026, including a £16 prescription cap and mandatory cost estimates, which should help. But until then, the smartest moves are: get lifetime insurance while your dog is young, ask for prescriptions and buy medication online, shop around for practices, and don’t ignore small problems before they turn into expensive ones.

Treat vet costs like any other major household expense. Budget for them, insure against the big ones, and stay ahead of the preventable stuff. Your wallet and your dog will both be better off for it.
