Neutering a dog in the UK typically costs between £180 and £350 for male castration, and between £250 and £500 or more for female spaying. The price depends on your dog’s size and weight, the vet practice you choose, and where you live. According to the CMA’s March 2026 vet market report, prices vary by as much as 156% between the most and least expensive areas.
That is a significant range, and it can feel confusing when you are trying to plan ahead. This guide breaks down exactly what you should expect to pay, what affects the price, and how to find the best value without cutting corners on your dog’s care.
How much does dog neutering cost by size?
Your dog’s size is the single biggest factor in the price. Larger dogs need more anaesthetic, longer surgery times, and bigger incisions. Here is what you can typically expect to pay across the UK in 2026.
Male dog castration costs:
| Dog Size | Weight | Typical Cost Range |
|---|---|---|
| Small (e.g. Chihuahua, Jack Russell) | Under 10kg | £150 — £220 |
| Medium (e.g. Cocker Spaniel, Beagle) | 10 — 25kg | £200 — £300 |
| Large (e.g. Labrador, German Shepherd) | 25 — 40kg | £250 — £350 |
| Giant (e.g. Great Dane, St Bernard) | Over 40kg | £300 — £400+ |
Female dog spaying costs:
| Dog Size | Weight | Typical Cost Range |
|---|---|---|
| Small (e.g. Chihuahua, Jack Russell) | Under 10kg | £200 — £300 |
| Medium (e.g. Cocker Spaniel, Beagle) | 10 — 25kg | £280 — £400 |
| Large (e.g. Labrador, German Shepherd) | 25 — 40kg | £350 — £480 |
| Giant (e.g. Great Dane, St Bernard) | Over 40kg | £400 — £550+ |
Female spaying is more expensive because it is a more complex procedure. It involves abdominal surgery to remove the ovaries and usually the uterus, whereas male castration is a simpler external procedure.
What affects the price of dog neutering?
Several factors influence how much you will pay. Understanding these can help you compare quotes fairly.
Dog size and weight. As shown above, this is the main cost driver. A heavier dog needs more anaesthetic and a longer procedure. Some practices price neutering by weight band rather than a flat fee.
Complexity of the surgery. Standard neutering is straightforward, but certain situations add cost. Female dogs in season or already pregnant will cost more to spay. Cryptorchid males (where one or both testicles have not descended) require a more involved operation, sometimes approaching the cost of a spay.
Chain vet vs independent vet. The CMA’s March 2026 report found that the six largest corporate vet groups charge on average 16.6% more than independent practices. For a neutering procedure, this could mean paying £30 to £80 more at a chain practice. The CMA identified that corporate groups now own more than 60% of UK vet practices, up from under 10% two decades ago.
Geographic location. Where you live makes a real difference. According to the CMA’s analysis, there is a 156% spread between the cheapest and most expensive areas for common veterinary procedures. London and the South East tend to be the priciest, reflecting higher operating costs. Practices in the North of England, Scotland, and Wales generally charge less.
Pre-operative blood tests. Some practices recommend or require blood tests before surgery, especially for older dogs. This can add £40 to £80 to the total cost. It is not always included in the quoted price, so ask.
Type of spay procedure. Some practices offer keyhole (laparoscopic) spaying for female dogs, which involves smaller incisions and a faster recovery. This typically costs £100 to £200 more than a traditional spay. Not all practices offer it.
What is included in the neutering price?
When a vet quotes you a price for neutering, it should normally include:
- A pre-operative health check or consultation
- General anaesthesia and monitoring during surgery
- The surgical procedure itself
- Pain relief medication (usually for the first few days)
- A post-operative check-up (typically 3 to 5 days and again at 10 to 14 days for stitch removal)
Some practices also include a protective collar (cone) and a take-home pack of pain medication. Others charge for these separately.
Always ask for an itemised quote so you know exactly what is and is not included. If a price looks unusually low, check whether the consultation, blood tests, or follow-up visits are extra.
How much does neutering cost by region?
Vet prices are not uniform across the UK. The CMA’s March 2026 report confirmed significant regional variation. While the CMA did not publish region-by-region neutering prices specifically, the overall finding was clear: pet owners in some areas pay more than double what others pay for the same procedures.
As a general guide based on available data:
| Region | Relative Cost |
|---|---|
| London and South East | Above average (often 20-40% higher) |
| South West | Slightly above average |
| Midlands | Around the national average |
| North of England | Below average |
| Scotland | Below average |
| Wales | Below average |
| Northern Ireland | Below average |
These are broad patterns. Individual practices within any area can vary widely, which is exactly why comparing prices locally matters. From late 2026, all UK vets will be required to publish their prices, making genuine local comparison much easier.
How to find a fair price for dog neutering
You do not need to accept the first quote you receive. Here are practical ways to find the best value.
Compare prices between practices. Call or check websites for at least three vet practices in your area. Ask for a full quote including all pre- and post-operative care. The difference between the most and least expensive option may surprise you.
Ask for an itemised quote. A single headline figure can hide extra charges. Asking for an itemised breakdown helps you compare like for like. It also gives you a clearer picture of what you are actually paying for.
Check charity options. Several UK charities offer free or heavily subsidised neutering for pet owners on low incomes:
- Dogs Trust runs neutering campaigns in some areas and may cover the full cost
- PDSA provides free and reduced-cost veterinary care, including neutering, for eligible owners
- Blue Cross offers subsidised neutering through some of its hospitals and partner practices
- Local councils sometimes run neutering voucher schemes — check your council’s website
Eligibility is usually based on receiving certain benefits such as Universal Credit, Pension Credit, or Housing Benefit.
Consider an independent practice. Given that independent vets charge on average 16.6% less than the major chains, according to the CMA, looking beyond the nearest corporate practice could save you a meaningful amount. You can check whether a practice is independently owned or part of a corporate group by asking directly or checking the RCVS Find a Vet register.

New transparency rules are coming
The CMA’s final report on the UK veterinary market, published on 24 March 2026, introduced new rules that will make comparing vet prices much easier.
From December 2026, large corporate vet chains (those with 10 or more practices) must publish their prices publicly. From March 2027, all remaining vet practices must do the same. This means every UK vet will have to show you what they charge for common procedures, including neutering, before you walk through the door.
This is the biggest change to vet pricing transparency in decades. It means no more guessing, no more awkward phone calls to ask for prices, and no more surprises.
Pawlee is building a free comparison tool to help you use these newly published prices to find the best-value vet near you. Once launched, you will be able to search by postcode and see neutering prices side by side across all practices in your area.

Is neutering worth the cost?
Beyond the immediate expense, neutering offers real health and practical benefits that make it a worthwhile investment.
For male dogs, castration reduces the risk of testicular cancer and prostate problems. It can also reduce roaming behaviour and aggression linked to hormones.
For female dogs, spaying before their first or second season significantly reduces the risk of mammary tumours and eliminates the risk of pyometra, a potentially life-threatening womb infection that the PDSA reports affects around 1 in 4 unspayed female dogs.
There is also the practical consideration of preventing unwanted litters. The Dogs Trust estimates that it cares for around 15,000 dogs a year, many of which are the result of unplanned breeding.
