At Petplan we like to be as clear as possible to our customers, therefore any exclusion from cover placed on your policy will be stated clearly on your Certificate of Insurance. Before taking out your dog, cat or rabbit insurance you must tell us about your pet's conditions and any prior illnesses or injuries they've had. Like most other pet insurance companies, illnesses and injuries experienced before you start your pet's insurance will unfortunately not be covered. Your pet's previous medical history will not affect your premium. When you take out a policy you should always check your terms and conditions in conjunction with your Certificate of Insurance to see what is and what is not covered.
