Can I cancel with Sanitas by email?
You must be able to prove that your notice arrived in time. The FOPH therefore recommends a registered letter or A-Post Plus. Check directly with the insurer whether Sanitas accepts cancellation by email or via its customer portal.
What happens to my supplementary insurance with Sanitas if I cancel my basic insurance?
Nothing: basic and supplementary insurance are separate contracts (Art. 7 paras. 7 and 8 HIA). You cancel supplementary insurance separately under the general terms and conditions of your product; the notice periods are set out there. Only cancel it once the new insurer has confirmed your cover in writing.
Do I have to give Sanitas a reason for cancelling?
No. You don’t need a reason and don’t have to answer a health questionnaire; the new insurer must accept you for basic insurance. Your insurance with Sanitas ends as soon as the new insurer has confirmed that your coverage continues without interruption.
