Are you looking for a property to buy in Wallonia, an apartment to rent in Brussels, or a plot of land to build on in Flanders? The first obstacle is not always the budget: it’s reaching the right person, at the right time, through the right channel. Contacting a real estate agency in Belgium is no longer just about walking through the door of a local office.
With online forms, instant messaging, and recent regulatory constraints, the way you make contact determines the quality of the follow-up that will follow.
Right of withdrawal and brokerage contract: what changes from 2024
Before even picking up the phone, it’s wise to know the legal framework that protects the Belgian consumer at the time of signing. As of February 1, 2024, a royal decree from September 28, 2023 replaces the old “AR Freya” from 2007 and fundamentally changes the rules of the brokerage contract.
The central point: a 14-day right of withdrawal applies regardless of where the contract is signed, whether the contract is concluded in an agency, at home, or remotely. Specifically, if you sign a mandate after an initial phone call or video conference, you have two weeks to retract your commitment without justification.
Some additional safeguards frame the relationship:
- Exclusive brokerage missions are limited to a maximum of six months, and non-exclusive missions can be terminated with a notice period of up to two months.
- Termination fees are capped (half of the commission during the first three months, a quarter thereafter).
- The real estate agent must report to the client at least once a month on the steps taken.
This framework secures remote contact. You can reach out to multiple agencies, compare proposals, and backtrack without being trapped by a contract signed too quickly. When you want to learn more about Immowatcher, the process illustrates this logic well: a clear contact form, with no prior commitment, that allows you to assess the service before committing.

Contact channels in Belgian real estate agencies: phone, WhatsApp, and form
The classic reflex remains the phone call or a visit to the agency. Most offices have fixed hours (typically Monday to Friday, with a break in the middle of the day) and offer appointments outside these hours upon request.
What has changed is the arrival of conversational channels. Several Belgian agencies now integrate WhatsApp as a primary contact channel, sometimes coupled with an artificial intelligence chatbot capable of qualifying the request before an agent takes over. The advantage is speed: you send a message at any time, receive an automated initial response, and then a human follow-up during business hours.
Web forms remain the most common channel. They allow you to detail your project (purchase, sale, rental, property management) and attach documents. Responses vary on this point: some agencies call back within the hour, while others take several days. A good indicator of seriousness is indeed the speed of response after the first form.
Which channel to choose based on your project
For a sale, prefer a physical appointment or a call: estimating the property requires in-depth exchange. For a search for purchase or rental, the online form is sufficient for an initial filter. It allows the agent to check the availability of matching properties before mobilizing you.
For property management (finding tenants, inventory, administrative follow-up), an exchange via email or messaging works well in the initial phase. The key is to specify from the first message the type of service expected and the location of the property.
Verify the professional before committing: IPI and mandatory mentions
Contacting an agency also means ensuring you are dealing with a licensed professional. In Belgium, every real estate agent must be registered with the Professional Institute of Real Estate Agents (IPI) and adhere to a code of ethics. This code has recently been updated to strengthen transparency obligations.
Check the agent’s IPI number before any signing. This number must appear on the agency’s communication materials (website, listings, business cards). Its absence is a warning sign.
Regarding listings, Belgian regulations impose mandatory mentions in every real estate publication. These mentions vary by region (Wallonia, Brussels, Flanders) but systematically include the energy performance certificate (PEB), the area, and the urban status of the property.

What the agency must communicate to you from the first exchange
- Its IPI registration number and proof of its professional liability insurance.
- The terms of the brokerage mandate (exclusive or not, duration, commission, termination conditions).
- A written summary of the planned steps, with a monthly reporting schedule in accordance with the royal decree of 2023.
If any of these elements are missing during the first contact, ask the question directly. An agent who is transparent about their obligations inspires more trust than a polished commercial pitch.
Save time: prepare your first contact with an agency
We often see poorly qualified requests that slow down the process on both sides. Before sending a message or making an appointment, gather concrete elements related to your real estate project.
For a sale: the title deed, the latest PEB certificate, available urban information, your desired price range. For a purchase: your actual budget (after bank simulation if possible), the targeted geographical area, the type of property sought, and your timelines.
For a rental: the property’s address, its current condition, the expected rent, and the desired management services (finding tenants only, or full management with rent tracking and coordination of works).
A structured first message with this information allows the agent to quickly assess your file and propose a targeted appointment rather than an exploratory exchange. The time savings are real for both parties.
The Belgian real estate market has a dense network of local agencies, each with its regional specialties. Whether your project concerns Brussels, Walloon Brabant, Namur, or Hainaut, the first contact remains the step that determines what follows. It’s worth taking care of it.
