Found a new insurer? How to avoid a gap in cover or double cover

Anyone in Switzerland who decides to optimise their policies and move to a cheaper or better-performing provider faces an organisational challenge. Whether you are switching health insurer, car insurer, private liability or household contents cover, the transition carries two treacherous risks that can cost consumers dearly — double cover (paying premiums on two policies at once) and a cover gap (suddenly having no insurance protection when a claim arises).

Anyone searching Google for terms like "switching insurance in Switzerland process", "avoiding double insurance", "cover gap terminating insurance" or "health insurance supplementary switch order" needs instructions that have been tested in practice.

This comprehensive guide shows you exactly what sequence you must follow when switching policies, how Swiss law (KVG vs. VVG) plays into it and how a clear strategy keeps you protected without gaps and without paying a single franc twice.

1. The two danger zones when switching: double insurance vs. cover gap

When switching policies, policyholders move along a narrow legal ridge between two extremes.

Risk A: double insurance (double cover)

Double insurance exists when the same risk is covered for the same period with two different insurance companies (for example two active private liability policies from 1 January).

The legal consequence: under the Swiss Insurance Contract Act (VVG), double insurance does not mean you receive twice the sum when a claim arises. Instead, the insurers are each liable only for their proportionate share. You do, however, pay two full premiums, which is money thrown away for nothing.
The cause: double cover usually arises when the new contract has already been concluded but the old policy has been extended by another year because the notice period was missed.

Risk B: the cover gap (under-insurance)

The cover-gap scenario is more dangerous still. Here the old policy ends before the new contract has officially come into force — or the new insurer unexpectedly rejects the application.

The legal consequence: if a loss occurs during that unprotected window (a road accident under motor insurance, say, or water damage in the flat), you have to meet every cost out of your private assets. With liability claims this can quickly threaten your financial existence.
The cause: terminating the old contract prematurely, without a binding cover commitment or policy from the new provider.

2. The legal framework: KVG vs. VVG makes the crucial difference

How the switch works in practice depends decisively on which law the insurance class in question falls under:

1. The Health Insurance Act (KVG) — compulsory basic insurance

Guaranteed acceptance: for basic insurance, Switzerland imposes a statutory duty to accept. No health insurer may turn you down because of your age, your state of health or your history.
No cover gap possible: the KVG ensures that protection carries over seamlessly. The old insurer may only lift cover once it has received confirmation from the new insurer that you are insured there from the following day. You must nonetheless keep strictly to the notice period (precisely by 30 November). AXA

2. The Insurance Contract Act (VVG) — supplementary and property insurance

No duty to accept: for supplementary insurance (supplementary outpatient hospital cover, dental insurance) as well as car, contents, liability and legal expenses insurance, freedom of contract applies. The company may reject your application without giving reasons or attach conditions (health exclusions). Smile Versicherung
The highest risk: anyone who terminates supplementary insurance before the new company has confirmed acceptance in writing may lose their protection permanently.

3. The correct chronological sequence when switching policies

To rule out both double insurance and cover gaps 100 per cent, you have to work through the switching process in a strictly defined order.

[Step 1: check the old contract and the deadlines] │ ▼[Step 2: request a new quote and submit the application] │ ▼[Step 3: wait for the binding policy / confirmation of acceptance] │ ▼[Step 4: terminate the old policy only AFTER acceptance] │ ▼[Step 5: check that the dates line up seamlessly (overlap)]

Step 1: analyse the old contract and the main renewal date

Look through your existing insurance documents. When does the insurance year end (main renewal date)? How long is the notice period? (For property insurance usually 3 months before expiry; for basic health insurance, by 30 November.)

Step 2: request a new quote and submit the application

Compare offers and submit the application to the new insurer. State the exact date on which cover is to start (e.g. 01.01.2027, 00:00).

Step 3: wait for the written confirmation (the policy)

This is the single most important rule when switching insurer: wait until the new insurer has sent you the written policy, the confirmation of acceptance or the insurance certificate. With VVG supplementary insurance you have to wait and see whether any exclusions are attached.

Step 4: terminate the old contract within the deadline

Only once the new insurer's written acceptance is in hand do you draft the termination of your old policy.

Since the VVG revision, text form (an email, for instance) is sufficient for many insurers; we nonetheless still recommend sending it by registered post or using certified digital termination services, so that you hold incontestable proof that it arrived on time. Smile Versicherung

Step 5: line the dates up to the day

Make sure the end date of the old insurance and the start date of the new one run into each other without a gap:

Old insurance ends: 31.12.2026, 24:00
New insurance begins: 01.01.2027, 00:00

4. Special case: using the statutory right of withdrawal under the VVG

If an overlap arises despite every precaution, or you signed a new contract too hastily, Swiss law has protected you since the revision of the Insurance Contract Act (VVG):

14-day right of withdrawal: for every newly concluded insurance contract you have the right to withdraw from the contract in writing within 14 days, without giving reasons. Funk Gruppe+ 1
When the period starts: the 14-day cooling-off period begins at the moment you applied for the contract or declared your acceptance. MME Legal
Practical use: if it turns out your old insurance is running for another year because a deadline was missed, you can withdraw from the newly concluded contract within 14 days and head off an expensive double insurance. Swiss Insurance Association SIA+ 1

5. Check-list: the golden guide to switching insurer

Before you act, work through this five-point check-list:

Identify the contract type: is it KVG basic insurance (guaranteed acceptance) or a VVG policy (rejection possible)? Allianz
Note the notice periods: how much lead time does the old provider require (30 November, or 3 months before the main renewal date)?
Keep to the order: get the new acceptance/policy first, then terminate the old contract.
A seamless cut-off: the expiry date of the old policy must match the start of the new one to the minute.
Secure the termination: keep the termination confirmation and the proof of posting carefully with your documents. Allianz

With this systematic approach you eliminate every financial and legal risk when switching policies, avoid paying premiums twice and enjoy uninterrupted protection in Switzerland.
