Send the cancellation to the address printed on your policy schedule (Versicherungsschein). If none is given there, the head office is the right address:
InterRisk Versicherungs-AG Vienna Insurance Group.For contracts signed after 30 September 2016 a letter or an email is enough: German law no longer allows consumer contracts to demand more than text form (section 309 no. 13 of the Civil Code). Give your policy number, your name and the date the contract should end, and ask for written confirmation. A German letter is not required, but it avoids delays.
If the contract can be taken out on the insurer's website, the site must also offer a clearly visible cancellation button (section 312k of the Civil Code).
Property, liability, accident and legal expenses policies
three months before the renewal date
These contracts usually run for a year and renew automatically. To end one, the cancellation has to reach the insurer three months before the renewal date, not merely be posted by then.
Special right to cancel: On top of that, a claim you have reported and a premium increase without more cover each open a one month window to cancel, whatever the renewal date.

Every year BaFin publishes how many complaints it closed about each company, split into eight classes of business. To make the figure meaningful we set it against the number of policies: complaints per 100,000 policies, next to the average of all insurers that report their portfolio.
| Class | Year | Complaints | Policies | per 100,000 | Market per 100,000 |
|---|---|---|---|---|---|
| General liability | 2025 | 2 | n/a | n/a | 0.55 |
| General liability | 2023 | 1 | n/a | n/a | 0.37 |
| Personal accident | 2025 | 3 | 544,411 | 0.55 | 0.16 |
| Personal accident | 2024 | 1 | 547,166 | 0.18 | 0.26 |
| Personal accident | 2023 | 1 | 539,587 | 0.19 | 0.19 |
| Contents | 2024 | 1 | 182,493 | 0.55 | 0.68 |
| Buildings | 2025 | 1 | 137,299 | 0.73 | 2.27 |
| Buildings | 2024 | 5 | 141,957 | 3.52 | 2.12 |
| Buildings | 2023 | 1 | 147,316 | 0.68 | 1.50 |
Rank 18 of 34 in Personal accident (2025), by complaints per 100,000 policies, lower is better.
Rank 5 of 46 in Buildings (2025), by complaints per 100,000 policies, lower is better.
What the figure does and does not say: BaFin does not assess whether a complaint was justified. A single large case can distort a year; BaFin attributes most of the 2025 increase to one single matter. Policy numbers are only shown where the company took more than 10 million euros in premiums in that class the year before, otherwise the table says n/a.
BaFin lists 7 classes of business under Annex 1 of the German Insurance Supervision Act for which the company holds a licence:
