Different policies will have different approaches to making policy amendments, and for this reason the answer varies depending on your pet insurance provider.
This information can be found in your Policy Wording, where you will find details regarding policy amendments, additional costs, and cancellation fees.
Please be aware that PetInsurance.co.uk is a comparison site, and for this reason we cannot assist with policy amendments directly. You will need to contact your chosen insurer directly to discuss any further queries regarding policy amendments.
