The verdict in three sentences
In Brussels, a website for a wealth management firm or family office built by a local agency is a 2026 ballpark of 6 000 to 35 000+ EUR, while a freelancer tends to ask 2 500 to 9 000 EUR, often without copywriting or a second language. Kolonell offers 2 700, 4 500 or 8 200 EUR fixed, with a bilingual FR/EN site from Premium, native copywriting, a project manager only 1 to 2 hours away and 3 months of support. To decide, compare the 3-year total cost, how languages are handled (Dutch is quoted separately) and how the supplier deals with regulatory pages and GDPR.
What does a wealth management website cost in Brussels in 2026?
The following ranges are prudent orders of magnitude, drawn from public rate cards of Belgian agencies, minimum project sizes on Clutch.co profiles and freelance platform rates (Malt, Upwork, Clutch listings). They vary with scope and the number of languages; they are not official figures.
| Option | Typical build price (EUR) | Delay | Usually included | Languages |
|---|---|---|---|---|
| Brussels full-service agency | 12 000 to 35 000+ | 8 to 16 weeks | Strategy, custom design, CMS, copy sometimes extra | Translations often billed per language |
| Brussels boutique studio | 6 000 to 15 000 | 6 to 10 weeks | Semi-custom design, build | External translation |
| Freelancer | 2 500 to 9 000 | 4 to 12 weeks | Design and build, copy supplied by the firm | Rarely handled |
| Kolonell Starter | 2 700 | 3 to 4 weeks | Core pages, native copy, one language | FR or EN |
| Kolonell Growth | 4 500 | 3 to 4 weeks | Starter plus bios, insights section, meeting booking | FR or EN |
| Kolonell Premium | 8 200 | Usually 4 to 6 weeks, written schedule at kickoff | Advanced design, richer architecture, content by client profile | Bilingual FR/EN, other languages quoted |
In Brussels, languages often weigh as much as design. For English-speaking partners running a family office in the EU quarter or Ixelles, the client base mixes Belgian business owners, EU officials and wealthy expatriates who read French and English; part of it also expects Dutch. Many agencies bill each translation per word through a third party unfamiliar with wealth vocabulary. At Kolonell, French and English are written natively in Premium, and Dutch is quoted on request. We have already delivered a trilingual FR/EN/AR site for Orven Properties (orvenproperties.com), an off-plan real estate advisory in Dubai, with project pages, investor guides and WhatsApp enquiries.
The three formulas are detailed on our international website offer.
What a Brussels family office site must contain
- Governance overview: who decides, how the investment committee works, independence from banks.
- Partner bios with background, designations and languages spoken.
- Investment philosophy and services: discretionary management, advisory, wealth structuring, philanthropy, without performance promises.
- Regulatory pages: status and licence where relevant, relationship disclosure, complaint procedure. The FSMA oversees advertising for certain financial products and services; your compliance officer must validate each page.
- Data protection: GDPR applies, supervised by the Belgian Data Protection Authority. Forms should collect the minimum, with a compliant privacy policy and cookie consent banner.
- Accessibility: the European Accessibility Act has applied since 28 June 2025 to certain services, and WCAG 2.1 AA remains the common reference.
- Discretion: many family offices want a restrained site, with no client list or assets under management displayed.
This is not legal advice: have these points confirmed by your counsel. An investor area with documents and reporting is a custom application, quoted on request.
How to compare quotes over 3 years
| Line to check | Brussels agency, typical | Kolonell Premium |
|---|---|---|
| Build | 6 000 to 35 000+ EUR | 8 200 EUR fixed |
| French copy | Often 1 500 to 5 000 EUR extra | Included |
| English version | Translation, often 2 000 to 4 000 EUR | Included, native copy |
| Dutch version | Translation extra | Quoted on request |
| Domain and access | Check the contract | Domain in the firm's name, all access handed over |
| Support after launch | Retainer from launch, often 150 to 500 EUR/month | 3 months included, then maintenance quoted |
| Payment | 3 to 4 milestones | 50 % at start, 50 % at delivery, bank transfer or Wise |
Red flags: a quote that does not say who writes the regulatory pages, unreviewed machine translation, a domain registered to the agency, a proprietary CMS licence without an exit clause, and numeric promises on leads. Ongoing search work is quoted on request at Kolonell, with no mandatory monthly package.
Mini case study
Illustrative example, not a real client. Thomas, partner at a multi-family office in Uccle, wants an FR/EN site, with Dutch later. A Brussels agency proposes 20 000 EUR for the build, 3 500 EUR for English translation and a 350 EUR monthly retainer. Kolonell proposes Premium at 8 200 EUR, both languages included.
With the same hypothetical maintenance of 350 EUR per month for both, after Kolonell's 3 included months:

- Brussels agency over 36 months: 20 000 + 3 500 + (36 x 350) = 36 100 EUR.
- Kolonell over 36 months: 8 200 + (33 x 350) = 19 750 EUR.
The gap is 16 350 EUR, about 45 % lower over 3 years under these assumptions. Thomas then sets up a Google Meet call at 10:00 Brussels time: with the team in Senegal (GMT), that is 8:00 or 9:00 for us depending on the season.
