Website redesign for a wealth management firm or family office in Brussels: budget, timeline and risks (2026)

The verdict in three sentences

For an English speaking wealth manager on Avenue Louise or a family office based in Uccle or Woluwe, a redesign must first build trust with entrepreneurial families and expatriates from the European institutions, without ever crossing into misleading financial promotion. The 2026 ballpark with a Brussels agency is €12,000 to €45,000 depending on the number of languages, versus €2,700, €4,500 or €8,200 on the Kolonell international grid, delivered in 3 to 4 weeks once content is approved. The risks that matter: a broken client login link, lost research archives and pages published without compliance sign-off.

How do you know your site needs a redesign?

A Brussels wealth manager's site ages quietly. Team bios no longer match, the Dutch version was only half translated, market notes pile up as unsorted PDFs, and the link to the client reporting platform points to an old address. Prospects comparing two or three firms before a first meeting often judge on exactly these details.

Regulatory status matters too. Depending on their activity, investment service providers are authorised and supervised by the FSMA and, for some aspects, by the National Bank of Belgium. MiFID II rules require client information to be fair, clear and not misleading, and that applies to website pages as well. A family office that does not provide regulated investment services should take care not to suggest otherwise.

What budget for a redesign in Brussels?

Typical Brussels agency quotes for a 15 to 35 page site in two or three languages give these ranges.

Every tier includes a project manager reachable in your time zone, native English or French copywriting, delivery in 3 to 4 weeks and 3 months of support. Review of the Dutch by an independent native translator is a third-party cost. A client area, integration with your reporting platform or CRM, and maintenance after 3 months are on quote.

What are the risks, and how do you avoid them?

The client login link. The most visible risk: a client who cannot find their login calls their manager the same day. List every link to third-party platforms, keep the same URL or redirect it, and notify clients a week before launch.

Research archives. Older market notes and quarterly letters should be sorted by date, migrated with their URLs or redirected. Each note keeps its publication date and a warning that past performance is not a reliable indicator of future results.

Search rankings. URL inventory in all three languages, a 301 redirect map per language, consistent hreflang tags and Search Console monitoring after launch.

Compliance. No page promises a return. Every text, chart and bio goes through the compliance officer before publication; build that sign-off into the schedule, as it often takes longer than development.

Personal data. GDPR applies, overseen by the Data Protection Authority (APD/GBA). The first-contact form is limited to identity, contact details and the subject of the request; the cookie banner makes rejecting as easy as accepting. This is not legal advice.

Is a Brussels agency sometimes the better choice?

Yes. If you are planning a full brand repositioning, a printed annual report, client events and ongoing advertising, a local agency specialised in private finance is the better fit, especially for in-person meetings. A remote studio is enough for a restrained, trilingual site with controlled redirects and a clear sign-off workflow.

Questions to ask: who holds the domain? How is compliance sign-off tracked? Who tests the client login links? Will archives keep their URLs?

Mini case study

Illustrative example: Philippe Vandenberghe runs a family office in Uccle serving entrepreneurial families. His trilingual local quote is €32,000 over 16 weeks. He picks Kolonell Premium at €8,200 (the multilingual tier, languages set in the quote: French, Dutch, English), plus €1,200 for Dutch review by an independent translator (third-party cost): €9,400, a €22,600 gap. If compliance spends 6 hours reviewing at a hypothetical internal cost of €120 an hour, add €720 of internal time, whichever provider he picks.

FAQ

How long does the redesign take?

With Kolonell, 3 to 4 weeks once content and compliance sign-off are in hand. Brussels agencies usually quote 10 to 20 weeks for a trilingual site.

Do you really need three languages in Brussels?

Not always, but a Flemish and international client base often justifies French, Dutch and English. The Premium tier at €8,200 sets the languages in the quote.

Can we publish historical performance?

It is governed by MiFID II client information rules: balanced presentation, reference period, a past performance warning. Have compliance approve every figure before publication.

What should we do with old market notes?

Migrate them with their date and URL, or redirect them to an archive page. For 50 to 200 notes, allow 1 to 3 days of migration in the schedule.

What does support include?

The first 3 months of support are included in every tier. After that, maintenance is on quote.
