What is a rental guarantee?

The rental deposit is a security for the landlord.

A rental guarantee serves the landlord as security for unpaid rent, ancillary costs or repairs in the event of damage.


It can be deposited in the form of a bank deposit (at a bank or Firstcaution) or a rental deposit insurance (e.g. Firstcaution).

In Switzerland, the rental deposit can be up to three months' rent.


How does a rental security deposit work in Switzerland?

In Switzerland, a rental security deposit is required in the vast majority of lease agreements. It must be provided before moving into the property and serves as financial security for the landlord.

When the security deposit is paid into a bank account, the account is blocked in the tenant’s name for the entire duration of the lease. In Switzerland, the landlord can only access these funds with the tenant’s agreement or following an official decision.

This system ensures a secure and transparent framework for both parties.

What is the amount of the security deposit in Switzerland?

In Switzerland, the amount of the rental security deposit for residential properties is legally limited to a maximum of three months’ rent.

In practice, however, the requested amounts generally vary:

  • 2 months’ rent in many cases
  • up to 3 months’ rent, especially in areas with high demand

This amount can represent a significant sum, which leads many tenants in Switzerland to look for alternative solutions.

Security deposit in Switzerland: bank account or insurance?

In Switzerland, there are two main solutions for setting up a rental security deposit:

The bank security deposit


The tenant blocks a sum of money in a dedicated account. This money remains unavailable for the entire duration of the lease.

Rental guarantee insurance in Switzerland


The tenant pays an annual or monthly premium (only with Firstcaution) instead of tying up a large amount of money. This solution is becoming increasingly popular in Switzerland because it allows tenants to preserve their liquidity.

Specialized companies such as Firstcaution offer this type of solution, making it easier to access housing without having to lock away significant capital.

Refund of the security deposit in Switzerland: how does it work?

In Switzerland, the security deposit is refunded at the end of the lease, provided that all of the tenant’s obligations have been fulfilled.

The refund mainly depends on:

  • payment of rent and additional charges
  • the condition of the property upon move-out
  • the agreement between the tenant and the landlord

In the event of a dispute in Switzerland, the funds may remain blocked until a solution is reached between the parties or an official decision is issued.

Why choose rental guarantee insurance in Switzerland?

Rental guarantee insurance in Switzerland is attracting more and more tenants.

It notably allows tenants to:

  • avoid blocking several months’ rent
  • manage their budget more effectively
  • make it easier to access housing

This solution is particularly suitable for people who want to keep their savings available or cover other expenses related to moving in Switzerland.
