How much does it cost to spay a dog in the UK? (2026 prices)

Spaying is usually the single biggest planned vet bill of a dog’s early life, and one of the few that insurance will never help with. This guide covers real 2026 UK prices for spaying and castration in dogs and cats, what moves the price, the low-cost routes, and where insurance does and doesn’t come in.

UK neutering prices in 2026

Procedure	Typical price
Dog spay — small breed (under 10kg)	£200 to £300
Dog spay — medium breed (10 to 25kg)	£250 to £400
Dog spay — large/giant breed (25kg+)	£300 to £500
Keyhole (laparoscopic) dog spay	Add £150 to £250 to the above
Dog castration	£150 to £300
Cat spay	£80 to £150
Cat castration	£60 to £100
Rabbit neutering	£80 to £200

All figures are typical private-practice prices; London and the South East sit at and sometimes above the top of each range, and individual practices genuinely vary — the same spay can differ by £200 between two clinics in the same town.

What’s included matters more than the headline number

When comparing quotes, ask what’s in the price. A cheap quote that excludes pre-operative bloods, pain relief to take home, a buster collar or surgical suit, and the post-op checks can end up costing the same as an all-in quote. The usual add-ons:

• Pre-anaesthetic blood test: £40 to £80 (optional for young healthy animals, often recommended)
• Take-home pain relief: usually included, sometimes £15 to £30
• Buster collar or surgical suit: £10 to £30
• Post-op checks: typically included (usually two)

Why size moves the price so much

Anaesthetic drugs, surgical time, and consumables all scale with bodyweight. A 45kg Rottweiler spay is a longer procedure with more anaesthetic agent and a bigger surgical field than a 5kg terrier — the price follows.

Keyhole spay: what the extra £150 to £250 buys

A laparoscopic spay removes the ovaries through two tiny incisions rather than one larger one. Recovery is faster and visibly more comfortable, with most dogs back to lead exercise within days rather than the traditional 10 to 14 days of strict rest. It needs specific kit and training, so not every practice offers it. For large, deep-chested, or very bouncy dogs, many owners consider it money well spent; for a small calm dog the traditional spay remains a perfectly good operation.

Does insurance cover any of this?

Routine neutering: no. Every standard UK policy classes neutering as elective, routine care — the same bucket as vaccinations, boosters, and worming. No mainstream insurer pays for it, and our what pet insurance covers guide maps the full in/out list.

Complications: generally yes. If a spay wound breaks down, infects, or the animal reacts to the anaesthetic, treatment of the complication is typically claimable as an illness like any other, subject to the excess. This is one of the quieter arguments for having cover in place before the operation rather than after it.

Conditions neutering prevents: yes, and this cuts both ways. Pyometra — the life-threatening womb infection of unspayed females — is a covered claim, and emergency pyometra surgery runs £1,500 to £3,000. Insurers cover it, but an unspayed bitch carries a meaningful lifetime risk of exactly this emergency, and some owners are caught out when a vet’s earlier note recommending spaying complicates the picture. Spaying also eliminates ovarian and uterine cancers and, done early, sharply reduces mammary tumour risk.

A few insurers nudge you. Some policies offer small premium discounts for neutered pets, reflecting the reduced risk of the conditions above. It’s never a large discount, but it’s worth declaring neutered status accurately at quote time.

Low-cost and charity options

Means-tested help is real and widely used:

• PDSA — free or low-cost treatment including neutering for owners on qualifying benefits, within catchment of a PDSA hospital
• Blue Cross — subsidised neutering at its hospitals and via voucher schemes, means-tested
• RSPCA — branch-level neutering vouchers and low-cost clinics; provision varies by area
• Cats Protection — cat neutering schemes that in many areas bring a cat spay down to £10 or less for eligible owners

Eligibility generally keys off benefits (Universal Credit, Housing Benefit, Pension Credit and similar) and postcode. If money is the barrier to neutering, ring the nearest branch of each before booking privately — the schemes exist precisely for this.

Timing: the question that’s changed

The old rule — spay everything at six months — has given way to something more breed-aware:

• Small breeds: around 6 months remains common practice
• Large and giant breeds: growing evidence associates early neutering with higher rates of joint disorders (including cruciate disease) in some big breeds, so many vets now advise waiting until skeletal maturity at 12 to 18 months
• Females: timing is also planned around seasons — most vets prefer to spay midway between seasons

None of this changes the cost much, but it’s the conversation to have at the puppy check rather than a decision to make from a price list.

Summary

Budget £200 to £500 to spay a dog in the UK in 2026 (£150 to £300 to castrate), £80 to £150 for a cat spay, and add £150 to £250 if you want keyhole. Insurance won’t pay for any of it — neutering is the textbook routine exclusion — but it will typically cover complications, and it will cover the £1,500 to £3,000 pyometra emergency that spaying prevents. Compare two or three local quotes on a like-for-like basis, ask the charities if eligibility might apply, and settle timing with your vet, not the calendar.
