When an agency requires you to go through Zelok to apply for an apartment, you find yourself facing a form to fill out without having chosen the platform. The question of trust arises in a very concrete context: you are entrusting copies of your ID, pay slips, and tax notices to an intermediary that you did not select.
Before uploading any documents, it is better to understand what Zelok actually does with your rental file and where the friction points are.

Zelok imposed by the agency: what it changes for the tenant
Most candidates discover Zelok not by choice, but because their real estate agency uses it as a management tool for applications. In practice, this means that refusing Zelok often amounts to giving up the housing.
This operation creates an asymmetry. The tenant has not negotiated the terms of use, does not know the duration of data retention, and does not always know which documents are legally required. Some users on Trustpilot report requests for supporting documents perceived as disproportionate, especially for atypical profiles (new job, recent unemployment period, multiple guarantors).

Zelok systematically responds that the platform complies with the Alur law framework. On this point, feedback varies: some candidates believe that certain requested documents exceed the list outlined by the decree governing required documents, while Zelok cites its activity as an insurance broker to justify additional supporting documents. We consulted several reviews on the reliability of Zelok that confirm this recurring tension between candidates and the platform.

Personal data and tenant file: the obligations that Zelok must respect
Since the implementation of the GDPR and the application decrees of the Élan law, the CNIL has multiplied reminders about the proportionality of the supporting documents requested in a rental file. Prohibition of certain documents, vigilance regarding scans of identity documents, strict regulation of data retention duration: these constraints weigh directly on any platform like Zelok.
As a candidate, you can check several points before submitting your documents:
- Does the platform display a privacy policy detailing the retention period for each category of data (identity document, income, professional situation)?
- Is there a mechanism for deleting data after the application process ends, or are the documents stored indefinitely?
- Do the requested supporting documents strictly correspond to the list set by the decree governing required documents for a rental, or do they include additional pieces related to unpaid rent insurance?
The distinction is central. A rental file and an insurance file do not follow the same rules. Zelok combines both roles (tenant file creation and unpaid rent insurance brokerage), which may explain requests for documentation that are broader than what a tenant expects.
Zelok’s solvency score compared to open banking alternatives
Zelok assesses the solvency of candidates based on documents submitted manually: pay slips, tax notices, employment contracts. This model relies on PDF files or photos, with anti-fraud controls (KYC checks).
Several recent players in the rental market offer a different approach. Based on open banking (access to bank statements via approved DSP2 APIs), these tools generate a real-time solvency score. The Banque de France and the ACPR present this type of solution as more reliable for assessing the risk of default and reducing document fraud.
The practical difference is clear. With banking scoring, the candidate authorizes a one-time and regulated access to their transactions. With Zelok, they submit copies of documents that can be falsified. The open banking model limits this risk at the source, as the data comes directly from the bank.
What it implies for choosing your method
If you have the choice between a document platform and a banking scoring tool, the latter option reduces the number of documents to submit and the risk of rejection for unreadable or incomplete documents. When the agency imposes Zelok, this alternative does not exist, but knowing these options allows you to ask the right questions to the agency about the chosen evaluation method.

User feedback on Zelok: concrete friction points
On Trustpilot, Zelok has an overall rating of 4 out of 5. Positive reviews highlight the speed of file creation and the user-friendliness of the interface. Negative reviews focus on several recurring irritants.
The first concerns the burden of the process for non-standard profiles. A candidate at the start of a contract, a freelancer, or a person with multiple guarantors faces dozens of additional documents. Zelok claims that a file can be created in a few minutes, but some users report estimates that far exceed this timeframe once their actual situation is provided.
The second friction point relates to communication. Several reviews mention a lack of clarity regarding the distinction between mandatory documents for the application and documents related to unpaid rent insurance. When you do not know why a document is requested, trust erodes.
The third concerns perceived cost. Creating a tenant file is free, but some expedited processing options are offered for an additional fee. For candidates already under pressure in a tight market, this distinction between free service and premium service generates frustration.
Zelok fulfills its role as a file centralizer for partner agencies, and the majority of users navigate the process without major difficulties. Frictions mainly arise at the margins: atypical profiles, lack of information on the purpose of requested documents, confusion between the free file and paid options. Before submitting your documents, check the legal list of required supporting documents and ask the agency why each additional piece is required.
