Efficiency and peace of mind for all

All Belgian tenants must arrange a rental security deposit by law. Generally, they hold this deposit in a blocked bank account. When they move out, the owner can use the deposit to fix any damage. After that, the tenant gets the rest of the deposit back.

Setting up a security deposit tends to take a lot of time. Taking out home insurance can also be a long process. Typically, tenants have to make several appointments. However, KBC has one easy, secure online process for a security deposit and home insurance. Even if the tenant is not a KBC customer. 

The KBC Security Deposit API allows real estate agents and owners to invite tenants to set up a deposit and insurance online. Tenants can click on a link to see their details and arrange their deposit and insurance. The system fills out most of the data already. The form is therefore very easy to complete. The real estate agent or owner also gets an email when the deposit is ready. 

This all-in-one service is quick and easy for everyone

  • Real estate agents have far less paperwork.
  • Tenants do not have to go to the bank.
  • Owners are happy with a quick deposit. 

And they all have this efficient API to thank.

The KBC website also has further details on KBC Security Deposits and Home Insurance.

KBC is a strong, reliable brand with an excellent reputation and a host of awards for many of its products and services. A dedicated account manager will regularly monitor the partnership with the merchant in order to keep optimising operations, supported by available dashboard services. The merchant can receive in-depth support from KBC from 8 am to 6 pm, Monday to Friday.

Who can offer the KBC Security Deposit?

Real estate software firms and property websites can use the KBC Security Deposit API in their applications for:

  • Real estate agents
  • Property websites
  • Property management companies
  • Letting agents
  • Owners

How does this solution work?

Step 1

Firstly, the real estate agent or owner enters the data for a new lease in his or her platform. When all the data is complete, the user clicks on the KBC Security Deposit API in the platform.

Step 2

Secondly, the real estate agent or owner completes a quick single-screen process in the KBC environment. The screen shows all the lease data. The user only has to enter the deposit amount. If any data is missing, the user can also add it here. When everything is complete, the user confirms.

Step 3

This then triggers an email to the tenant. The real estate agent or owner also receives a confirmation.

Step 4

The tenant can then click on a link in the email to start to set up a rent deposit account. The tenant can also take out home insurance at the same time. Again, all the available data is prefilled already.


If the merchand activates “webhooks”, he will receive status updates of his requests.

KBC partner requirements 

The selected merchant signs a Partnership Agreement. This agreement describes the partnership's scope and operating model. Our FAQ section offers further details on the Partnership Agreement.

No special mediation rules apply to real estate software firms, real estate agents and owners who use the KBC Security Deposit API. This is because they only refer tenants to a security deposit and home insurance. They do not offer any advice, and let the tenants decide.
