Dog and cat neutering costs explained

Neutering is a planned surgical procedure, which means you have time to compare options, ask questions and understand what is included before booking. It is also one of the more significant routine veterinary costs for many pet owners.

This guide explains what affects neutering costs, what to check before booking, and how to compare practices.

Source note: This guide is based on the CMA's veterinary market investigation final decision report and supporting materials. It does not provide veterinary or medical advice. Decisions about whether and when to neuter should be discussed with your vet.

What neutering involves

Neutering refers to surgical sterilisation:

• Castration — the removal of the testes in male dogs and cats. This is typically a less complex procedure with a shorter anaesthetic time.
• Spaying — the removal of the ovaries (and usually the uterus) in female dogs and cats. This is a more complex abdominal procedure requiring more anaesthetic time and surgical skill.

Both procedures are performed under general anaesthetic and require a period of recovery and post-operative monitoring.

What affects neutering costs

Neutering costs vary because:

Species and sex — spaying a female cat involves a different procedure and recovery than castrating a male cat. The same applies to dogs. Female animals typically cost more to neuter than males of the same species.

Size and weight — larger dogs require proportionally more anaesthetic and may require more time and resources. Many practices price neutering on a weight or size band basis for dogs.

What is included — the quoted price may or may not cover the pre-operative health check or consultation, anaesthetic, pain relief to take home, a follow-up check, and any additional monitoring during recovery. Always ask what is and is not included.

Practice type and location — practices in higher-cost areas or with specialist facilities will typically charge more. A practice with a dedicated surgical suite or specialist veterinary surgeon may differ in pricing from a general practice.

Animal health — if your pet has a health condition that requires additional pre-operative assessment or anaesthetic management, this can affect cost.

The CMA's standardised price-list remedy (Final decision report — Part B) lists neutering as a category practices will be required to publish prices for. Remedies are being phased in over time; for the current position confirm via the GOV.UK landing page in Sources above.

What to ask before booking

Before booking a neutering appointment, you can reasonably ask:

• What is the total cost for neutering my [dog/cat], including all elements (pre-op check, anaesthetic, post-op pain relief, follow-up)?
• Is the price based on weight or size, and what category does my pet fall into?
• What monitoring is included during and after the procedure?
• What aftercare advice and support is provided?
• What should I do if I am concerned after the procedure?

Ask for a written estimate before agreeing if you want to avoid unexpected charges.

Timing

Your vet will advise on the appropriate timing for neutering based on your pet's age, breed and health. This is a clinical decision, not primarily a financial one. Do not delay or rush a neutering decision to fit a promotional offer — discuss the timing with your vet.

Comparing neutering prices

Neutering is listed in the CMA's recommended price categories because it is a routine, comparable service. You can compare available neutering prices for local practices on WisePet.

Where practices have shared price data, neutering prices appear on their listings. Data availability varies. The CMA's transparency remedies are intended to increase the amount of price information available over time.

Charitable and subsidised neutering

Some charities and organisations offer subsidised neutering for pet owners who cannot afford standard practice fees. Search for subsidised or low-cost neutering in your area, or contact the PDSA, Cats Protection, Dogs Trust or your local animal welfare organisation to find out what is available.
