Age - The older your pet gets, the more expensive your cover is likely to be. This is because your pet is more prone to chronic medical conditions in later years. Rising vet fees - Fees are increasing throughout the UK because vets can now provide more advanced treatments. Breed - Some breeds are more expensive to insure as they're more susceptible to certain medical conditions. IPT - If Insurance Premium Tax either increases or decreases, insurance premiums are impacted. Introductory discounts - If the price you've paid today includes an introductory or renewal discount, you might find your insurance is higher in following years once the offer ends. Other factors including, but not limited to, the age and breed of your pet or claims history could also have an impact on your premium at renewal.
