Pets, Vets and Pet Insurance

New rules from the Competition and Markets Authority will make vets publish prices, cap prescription fees, give written estimates and offer mediation, starting between late 2026 and 2027. Pet insurance complaints go to the insurer and then the free Financial Ombudsman Service.

Your Rights

What the rules say, with a link to the official source for each.

Vets

  • Prices and Prescriptions

    Vets must publish price lists for standard care (larger businesses by about December 2026, smaller by about March 2027). Written prescription fees will be capped at £21 for the first medicine and £12.50 for each extra one, from about March 2027 (larger) or September 2027 (smaller). source

  • Estimates

    You must get a written estimate when treatment is likely to cost £500 or more, with an update if it is likely to rise by 20% or £500, whichever is lower (from about June 2027 for larger businesses, September 2027 for smaller). source

  • Vet Complaints

    Practices must publish their complaints process, acknowledge complaints within 5 working days and give a full response within 8 weeks, then take part in mediation if you wish. These rules apply by about March 2027. source

  • Care and Skill

    Vet services must be carried out with reasonable care and skill. If not, you can ask for the work to be redone or for a price reduction. source

Pet Insurance

  • Why Claims Are Refused

    Common pet insurance complaints include claims refused for pre-existing conditions, exclusions such as dental treatment, price rises, excesses, co-payments and limits, and backdated exclusions. source

  • Policy Types

    Annual policies cover a condition for 12 months; lifetime policies cover your pet for life as long as you renew; some are accident and illness only; trial cover usually lasts four weeks. source

  • The Financial Ombudsman

    The Financial Ombudsman looks at vet records, the policy terms and what you were told when you bought the policy. It can tell the insurer to put things right and pay for distress or inconvenience. Complain to the insurer first. source

Where to Go If It Is Not Put Right

Free routes to escalate, and when each one applies.

The Vet Practice

Always start here, in writing.

Mediation

After the practice's full response, once the new rules apply.

Financial Ombudsman Service

Pet insurance complaints, after 8 weeks or a final response. Free.

Steps to Take

Step 1 of 5

Ask your vet for prices and a written estimate before treatment.

Step 2 of 5

Ask for a written prescription if you want to buy medicine elsewhere.

Step 3 of 5

Complain to the practice in writing if something goes wrong.

Step 4 of 5

For insurance, check whether your policy is annual or lifetime and what it excludes.

Step 5 of 5

Complain to the insurer, then the Financial Ombudsman after 8 weeks or a final response.

Common traps and scams to avoid.

Assuming the new vet rules already apply: most start during 2027.
