Dog castration costs £180 to £400 on average in 2026. Your dog's size is the biggest factor — larger dogs need more anaesthetic and longer surgery time.
The vet removes the dog's testicles under general anaesthetic. It's a routine procedure, and most dogs go home the same day.
London and South East practices usually charge more. Vets in rural areas and the North often offer lower prices.

Why Do Dog Castration Costs Vary Across the UK?
Dog Size and Weight
Larger dogs need more anaesthetic and the surgery takes longer, increasing the cost of materials, medications, and theatre time.
Location
Veterinary practices in London and the South East often have higher overheads, which can affect pricing.
Clinic Facilities
Practices with modern surgical facilities, advanced monitoring equipment, or specialist staff may charge more.
Undescended Testicles
If one or both testicles are retained (cryptorchid), a more complex surgery is required, which increases the cost.
