Cat Castration
Cost UK
Cat castration (male neutering) costs £50 to £100 in the UK in 2026. It is one of the quickest and most affordable veterinary procedures. Many charities offer free or subsidised cat castration.
What You Will Pay
Male cat castration is a simple, quick procedure that prevents unwanted kittens, reduces fighting and roaming, and eliminates the pungent smell of unneutered male cat urine. It is strongly recommended by all UK veterinary and welfare organisations.

Factors That Affect
the Price
Location
London practices charge £80-£100. Northern England and Scotland typically £50-£70. Rural practices and charity clinics offer the lowest prices.
Practice type
Charity clinics are cheapest or free. Independent practices are mid-range. Corporate chains are typically 20-30% more expensive.
Cryptorchid cats
If one or both testicles are retained (undescended), the surgery is more complex — essentially abdominal surgery costing £150-£400. This is still recommended as retained testicles can become cancerous.
Age
Standard castration age is 4-5 months. Older, larger cats may cost slightly more due to longer anaesthesia. The procedure is straightforward at any age.
How to Save Money
Get free castration from Cats Protection
Cats Protection offers neutering vouchers accepted by participating vets. Check their website for eligibility and local participating practices.
Contact PDSA
The PDSA provides free castration for cat owners receiving certain means-tested benefits. Apply through their website or visit a local PDSA Pet Hospital.
Ask about multi-cat discounts
If you have multiple cats needing neutering, some practices offer a discount for booking them on the same day, saving on per-cat anaesthesia and consultation costs.
Do not wait
Male cats can father kittens from 5-6 months old. Early neutering at 4 months prevents this, reduces spraying behaviour before it becomes a habit, and is cheaper than dealing with the consequences of an unneutered tom.
Would insurance have covered this?
On a typical lifetime policy an owner pays the excess (usually £60–£200) and, on some policies, 10–20% of the rest. Pre-existing conditions are never covered, so the time to compare is before something goes wrong.

Frequently Asked Questions
Cat castration costs £50-£100 at a vet in the UK in 2026. Charity clinics (Cats Protection, PDSA, Blue Cross) offer free or subsidised castration for eligible owners.
Most vets recommend castration at 4-5 months, before the cat reaches sexual maturity. Early neutering from 8 weeks is practised by some charities and is safe.
Castrated cats are generally calmer, less aggressive, less likely to roam, and less likely to spray urine. They retain their individual personality. The biggest change is reduced territorial aggression and wandering.
Recovery is very quick — most cats are back to normal within 24-48 hours. The wounds are tiny and often do not need stitches. Keep your cat indoors for 24-48 hours after surgery and monitor the wound site.
Yes. Cats Protection, PDSA, Blue Cross, and the RSPCA all offer free or subsidised neutering. Local councils sometimes run free neutering campaigns. Check your eligibility online.
