The verdict in three sentences
For a wealth management firm or family office in Brussels, a local agency typically quotes about 12 000 to 50 000 EUR for a new website in 2026, more with agencies specialising in private banking, while a remote studio like Kolonell works at a fixed 2 700, 4 500 or 8 200 EUR. A Brussels agency remains preferable if you want a trilingual French, Dutch and English site produced in house, brand workshops with the partners or a client area linked to your reporting tools; a remote studio suits a house that wants a sober, discreet, well written site delivered in 3 to 4 weeks. The choice should rest on discretion, rigour in regulatory wording and ownership of the site, far more than on proximity.
This version is written for the English-speaking partners of wealth management firms and family offices in Brussels.
Why is a Brussels wealth management website different?
Brussels brings together an unusually diverse clientele: Belgian entrepreneurial families settled in Uccle, Ixelles or Walloon Brabant, senior EU officials and diplomats on posting, international executives drawn by the proximity of Paris, Amsterdam and Luxembourg. Independent houses on Avenue Louise or in the European Quarter sit alongside family offices that do not wish to be found. The site rarely serves to attract a stranger: it reassures a referred prospect, confirms the seriousness of the house and filters enquiries. It must therefore be sober, accurate and silent on performance.
What do agencies, freelancers and a remote studio charge in Brussels?
Clutch.co profiles of Brussels agencies often show minimum projects of 5 000 to 25 000 EUR, and day rates published by Belgian studios frequently range from 550 to 950 EUR. Freelancers on Malt or Upwork cost less, but financial copywriting and managing three languages remain your job. The table below is a 2026 ballpark from those public sources.
| Option | 2026 ballpark | Timeline | Languages | After launch |
|---|---|---|---|---|
| Private banking and finance specialist agency | 25 000 to 50 000+ EUR | 12 to 20 weeks | FR, NL, EN often in house | Annual retainer |
| Brussels generalist agency | 12 000 to 25 000 EUR | 8 to 12 weeks | FR and NL, EN sometimes outsourced | Day rate |
| Freelancer | 3 000 to 9 000 EUR | 4 to 10 weeks | Depends on profile | Ad hoc |
| Kolonell Starter | 2 700 EUR | 3 to 4 weeks | FR or EN, native copy | 3 months support |
| Kolonell Growth | 4 500 EUR | 3 to 4 weeks | FR or EN, full approach and services pages | 3 months support |
| Kolonell Premium | 8 200 EUR | Usually 4 to 6 weeks | Bilingual FR/EN; Dutch supplied or quoted separately | 6 months support |
The tiers are set out on our international website offer.

Our team works on GMT, one to two hours behind Brussels depending on the season: calls take place in the morning or early afternoon, with a written update every week.
What should a wealth management site contain, and leave out?
- Philosophy and approach: governance, independence, investment horizon, with no performance figures or return promises.
- Services: discretionary management or advisory, estate and succession planning alongside notaries and lawyers, family structuring, support for expatriates; for a family office, coordination of advisers and consolidated reporting.
- Clients served: families, entrepreneurs after a sale, foundations, international civil servants, with a minimum relationship size if you wish to display it.
- Team and governance: partners' backgrounds, without overstatement.
- Filtered contact: a short form (source of referral, nature of the need, preferred language), without asking for detailed amounts.
- Regulatory notices: status of the firm, licence and supervisory authority if you are regulated, complaints policy, privacy policy.
On compliance, kept factual: in Belgium the FSMA supervises, among other things, the conduct of business rules applying to investment service providers, and MiFID II governs information given to clients, which must be fair, clear and not misleading; an unregulated family office must avoid implying otherwise. Forms fall under the GDPR, supervised in Belgium by the Data Protection Authority. The European Accessibility Act has applied since 28 June 2025 to certain consumer financial services, and WCAG 2.1 AA is a good technical reference. This is not legal advice.
When is the Brussels agency the right choice, and when is it not?
The local agency is the right choice if you need three perfectly balanced languages from launch, identity work with several generations of a family around the table, or a client area connected to your reporting tools. Its physical presence and command of Dutch are then worth the price.
The remote studio fits better if your identity is established, you work mainly in French and English, and your current site is dated, too wordy or contains phrasing your compliance officer no longer approves. Kolonell has not yet delivered a wealth management site; our references are a bilingual FR/EN site for a notary firm in New Jersey (trsigninggroup.com) and a trilingual site for an off-plan property advisory firm in Dubai. Judge us on the precision of the written scope.

Which questions should you ask before choosing?
- Who writes the copy, and how many review rounds with our compliance function are planned?
- Who has access to content during the project, and is an NDA signed?
- Can the site stay discreet (no indexing of certain pages, no client list)?
- Are the domain and hosting in our name?
- What does maintenance cost after the support period?
Red flags: a provider proposing to display past performance, client testimonials or custodian logos without checking your obligations, a quote without written scope, or hosting in the agency's name.
Mini case study
Illustrative example. Laurent D., founding partner of a five-person independent wealth manager in Ixelles, receives a quote of 34 000 EUR from a specialist agency for a trilingual site with a client area. His clients correspond in French and English; a few Flemish families prefer Dutch. He chooses Kolonell Premium at 8 200 EUR for a bilingual FR/EN site, has eight pages translated into Dutch by a Belgian financial translator for about 1 600 EUR, and books a photographer for 600 EUR. Total: 10 400 EUR versus 34 000 EUR. Assuming identical maintenance on both sides after the 6 months of support, the gap of 23 600 EUR leaves room to scope the client area separately if demand is confirmed.
FAQ
How much does a family office website cost in Brussels in 2026?
Ballpark: 12 000 to 50 000+ EUR with a local agency, 3 000 to 9 000 EUR with a freelancer, and 2 700, 4 500 or 8 200 EUR with Kolonell. The three languages and the client area explain most of the gap.
Can you deliver the site in Dutch?
Bilingual FR/EN is included from Premium at 8 200 EUR; Dutch is supplied by you or quoted separately. For a few pages, a Belgian financial translator often charges around 0.15 to 0.25 EUR per word.
Will you display our performance?
No, we advise against any performance figures on the site, and every page goes through your compliance sign-off. The site highlights approach, governance and team.
Can you build a client area with reporting?
Yes, as a custom application quoted separately. The marketing site starts at 2 700 EUR and can link to it.
How does payment work?
Bank transfer or Wise, 50 % at the start and 50 % at delivery, with 3 months of support after launch (6 months in Premium).
