Make your online presence fit in with the Belgian market

A guide to localisation for Belgium

1 Overview

We’ve created this guide to help you get closer to your Belgian customers. A web presence that is in tune with Belgium’s culture will make your customers feel well disposed to you, and give them confidence in doing business with you. Get the little details right, and you'll be in a good position right from the start in your new market.

2 Main Language

Dutch, and French are the official languages of Belgium. Even though it is a multilingual country, most customers would expect communications to be in Dutch. Most Belgians can speak English, and the majority of business communications would expected to be carried out in English.

Three distinct cultures exist in parallel in Belgium. These are Flanders with a mainly Dutch-influenced populace, Wallonia with a mainly French-influenced populace, and the North East which has a mainly German-influenced population.

It is therefore important to set up your online presence to address people in their preferred language. If you are in any doubt, address people in English.

In the capital Brussels there are two official languages: Dutch and French.

3 Formality

Should you be formal or informal when addressing your customers?

Because Flemish is a naturally down to earth, plain-speaking language, people expect to be communicated to in a straightforward way.

With the exception of professors and lawyers, you shouldn’t address people by their titles. This is looked at as being too formal.

When first doing business with people, avoid addressing them by their first name until you have a firm relationship with them.

If you choose to address your customers in French, use the more formal term of “vous” instead of “tu.”

Writing about your company or your product in too exuberant a manner will flag you up as not being in tune with Belgian locals.

If you have a financial product, a legal service, or are talking about money, you should adopt a more formal tone and style.

The Belgians trade in Euros. This is represented by the euro symbol € and its trading three letter code is EUR. The € is placed after the figure. The coin denomination is the cent represented by a c.

Date and time formats

When writing the date in full, use a full point after the day. So in English it is: "Sat.9 Sep 2017".

7 Hour formats

The 24-hour clock is used in Belgium.

When writing, time is expressed in the 24-hour format using a colon to separate hours and minutes, e.g. 20:00 in Belgian English.

10 Important localisation tips

We’ve found the top translation rules to follow in a new market. Take a look, and you will sound like a local in no time.

  1. Try not to stay too close to the English source when you choose your words and word order, as this will result in a literal, unnatural sounding translation

  2. Be wary of using old-fashioned terms e.g. 'koppeling' instead of 'link'

  3. Be careful not to use too many English terms that have perfectly fine Dutch translations

  4. Stay clear of colloquialisms and expressions used in your language, as they may not translate in your Belgian market. For example local slang

  5. Take account of cultural differences so you don’t confuse or offend your Belgian audience. For example, avoid mentioning Boxing Day as this is purely a British tradition

  6. Be careful with tone. English source texts can be overly enthusiastic or overly apologetic. The Dutch language is more down to earth and straightforward
