Spaying a female cat in the UK typically costs between £120 and £200 or more, while neutering (castrating) a male cat costs between £80 and £140. The exact price depends on your vet practice, where you live, and your cat’s weight. According to the CMA’s March 2026 vet market report, vet prices can vary by as much as 156% between different areas of the UK, so comparing prices locally is well worth your time.
Whether you have just brought home a new kitten or you are looking into neutering an older cat, this guide covers everything you need to know about the cost, what is included, and how to find a fair price.
How much does it cost to neuter a cat?
The cost differs depending on whether your cat is male or female. Female spaying is more expensive because it is a more involved surgical procedure.
| Procedure | Typical Cost Range |
|---|---|
| Female cat spaying | £120 — £200+ |
| Male cat castration | £80 — £140 |
These are typical prices for a straightforward procedure on a healthy, normal-weight cat. Overweight cats, cats in season, or pregnant cats may cost more.
How much does cat spaying cost by region?
Where you live has a real impact on what you will pay. The CMA’s March 2026 report found significant regional price variation across all common vet procedures. London and the South East are consistently the most expensive areas for vet care.
| Region | Female Spay (Typical) | Male Castration (Typical) |
|---|---|---|
| London and South East | £160 — £250+ | £100 — £170 |
| South West | £140 — £210 | £90 — £150 |
| Midlands | £120 — £190 | £80 — £140 |
| North of England | £110 — £180 | £75 — £130 |
| Scotland | £100 — £170 | £70 — £120 |
| Wales | £100 — £170 | £70 — £120 |
| Northern Ireland | £100 — £160 | £65 — £120 |
These are indicative ranges. Individual practices within any area can charge above or below these figures. The CMA found that the spread between the cheapest and most expensive areas was as high as 156% for common procedures.
What affects the price of cat spaying?
Several factors influence the cost. Understanding them helps you compare quotes on a like-for-like basis.
Gender. Female cat spaying costs more than male castration. Spaying involves abdominal surgery under general anaesthetic to remove the ovaries and usually the uterus. Male castration is a simpler procedure with a smaller incision and shorter anaesthetic time.
Weight. A heavier cat needs more anaesthetic, which increases the cost. Some practices charge by weight band rather than a flat fee. An overweight cat may also require additional monitoring during surgery.
Geographic location. As the regional table above shows, location matters. Practices in London and the South East face higher rent, staffing costs, and overheads, and those costs are passed on. The PDSA’s 2025 PAW Report found that 52% of UK pet owners are worried about affording vet care, and regional price differences are a significant part of that picture.
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 cat spay, that could mean a difference of £20 to £40 or more. Corporate groups now own more than 60% of UK vet practices, so it is worth checking whether your local practice is independently owned.
Age and health. Older cats or those with health conditions may need pre-operative blood tests (adding £40 to £80) or extra monitoring. Kittens being neutered at the recommended age of around 4 months are usually straightforward.
Cat in season or pregnant. Spaying a female cat that is currently in season or pregnant is more complex and carries a higher risk. Most vets charge more for this, sometimes significantly so. It is generally better to wait until a cat is out of season if possible.
What is included in the spaying price?
A standard cat spaying or neutering quote should typically include:
- A pre-operative health check
- General anaesthesia and monitoring
- The surgical procedure
- Pain relief medication for the first few days
- A post-operative check (usually 3 to 5 days after surgery)
- Stitch removal if non-dissolvable stitches are used (usually at 10 to 14 days)
Some practices also include a protective collar and take-home medication in the price. Others list these as extras.
Ask for an itemised quote before booking. If a price looks particularly low, check whether the consultation fee, any blood work, or follow-up appointments are charged separately. A transparent practice will be happy to explain exactly what is included.
How to find a fair price for cat spaying
You have more options than you might think. Here are practical steps to get the best value.
Compare prices between at least three practices. Ring around or check websites. Ask for a full quote including everything — consultation, surgery, anaesthetic, pain relief, and follow-ups. The difference between the highest and lowest quotes in your area could be £50 to £100 or more.
Check charity neutering schemes. Several UK charities offer free or heavily subsidised cat neutering. This is one of the areas where real help is available:
- Cats Protection is the biggest provider of subsidised cat neutering in the UK. Their campaigns regularly offer free neutering in targeted areas. Check catsprotection.org for current schemes near you.
- PDSA provides free veterinary care, including neutering, for owners receiving qualifying benefits such as Universal Credit, Pension Credit, or Housing Benefit.
- RSPCA runs neutering campaigns in various areas throughout the year. Check with your local RSPCA centre.
- Local councils sometimes offer neutering voucher schemes, particularly for cat population control. Check your council’s website.
Consider an independent practice. Given the CMA’s finding that independent vets charge on average 16.6% less than corporate chains, it is worth looking beyond the nearest big-name practice. Ask the practice directly whether they are independently owned, or check the RCVS Find a Vet register.

New price transparency rules are coming
The CMA published its final report on the UK veterinary market on 24 March 2026. The headline change is that all vets must now publish their prices publicly.
| Milestone | Date |
|---|---|
| CMA final report published | 24 March 2026 |
| Large chain vets must publish prices | December 2026 |
| All remaining vet practices must publish prices | March 2027 |
This is a significant shift. Until now, many practices have not displayed prices openly, making it difficult to compare without calling around. From late 2026 onwards, you will be able to see what a practice charges for cat spaying before you make contact.
Pawlee is building a free price comparison tool that will let you search by postcode and compare cat neutering prices across all local practices side by side. No more guesswork, no more awkward phone calls.

Why neutering your cat matters
Beyond the cost question, neutering your cat is one of the most important things you can do as a responsible owner. The benefits are real and well-documented.
Preventing unwanted litters. Cats Protection estimates that a single unneutered female cat can be responsible for 20,000 descendants over just five years. The UK already has a significant stray cat problem. Neutering is the single most effective way to prevent it.
Health benefits for female cats. Spaying eliminates the risk of ovarian and uterine cancer and greatly reduces the risk of mammary tumours, particularly if done before the first season. It also prevents pyometra, a serious and potentially fatal womb infection.
Health benefits for male cats. Castration reduces the risk of testicular cancer and decreases roaming, fighting, and spraying behaviour. Unneutered male cats are far more likely to roam, get into fights, and pick up infections including FIV (feline immunodeficiency virus), which is spread through bite wounds.
Quality of life. Neutered cats generally live longer, healthier lives. They are less likely to roam far from home, less likely to fight, and less likely to spray indoors.
The RSPCA, Cats Protection, the BVA, and the RCVS all recommend neutering as standard responsible cat ownership.
