You might think that an accident only policy is appealing because it’s the cheapest pet insurance available. But it’s important that you understand that accident only policies offer no cover or very limited cover for illnesses. Illnesses can tend to cost more in the long run, particularly if you have a pedigree cat or dog that is known to suffer from hereditary diseases. If you take out an accident only pet insurance whilst your pet is young and they develop a lifelong condition such as arthritis, you will be unable to claim for this condition for as long as your pet needs treatment for it. Basic treatment for arthritis can cost around £5,475 a year. You won’t be able to claim any of these costs back if you have an accident only policy. Even if you want to change insurer or change policy type in the future, you would have to declare the condition as pre-existing and cover for that particular condition would be excluded. It’s really important to bear this in mind if you’re considering an accident only policy because your pet could end up becoming a financial burden in the future if you opt for a cheaper, less comprehensive policy when they’re young.
