Website redesign for a management consultancy in Brussels: budget, timeline and risks (2026)

The verdict in three sentences

For a management consultancy in Brussels, a website redesign in 2026 costs €12,000 to €50,000 with a local agency, against Kolonell's fixed grid of €2,700 (Starter), €4,500 (Growth) and €8,200 (Premium). The build takes 3 to 4 weeks once content is ready, but a trilingual firm should plan two to four weeks of preparation first. The real risk sits in the insights archive and author pages: migrated carelessly, they take with them the visibility the firm spent years building.

Which signs show a redesign is due?

• Insights are listed by date, with no topic or author: a federation director cannot find your work on governance or transformation.
• The Dutch and English versions lag six months behind the French one.
• Case studies name clients whose written consent was never filed.
• The contact form asks for job title, organisation size, budget and VAT number before any conversation.
• Partners cannot publish an article without going through the developer.
• The site takes more than 4 seconds to load on mobile, while your contacts in the European Quarter, Louise or Ixelles read it between meetings.

What budget should you plan in Brussels in 2026?

Figures are a 2026 ballpark from typical Brussels agency quotes and public agency rate pages: ranges, not a price list.

Every Kolonell tier includes a project manager reachable on Brussels time, native English or French copywriting, delivery in 3 to 4 weeks and 3 months of support. A native Dutch review is a third-party cost if you hand it to a freelance translator. Tier details are on the international offer page.

How long does the redesign take, phase by phase?

Search Console monitoring continues for 6 weeks after go-live.

Which risks, and how do you control them?

• Traffic loss on insights that rank: inventory of 100% of URLs, line-by-line 301 redirect map, weekly Search Console checks for 6 weeks.
• Lost author pages: each consultant keeps their URL or gets a redirect, with their list of articles.
• Case studies without consent: migrate only those with filed written client consent; the others become anonymised cases. Never a figure the client has not approved, never an invented ranking or award.
• Language lag: launch all three languages together, or clearly flag a partial version, rather than empty pages.
• Greedy forms: minimum fields (name, organisation, email, topic), clear GDPR information, the Data Protection Authority (APD/GBA) referenced in the privacy policy.
• Downtime: DNS switch on a Friday evening, TTL lowered 48 hours before, usually under one hour of disruption.

What stays on quote: CRM integration, client area or extranet, embedded booking tool, events or webinar platform, any custom application. If you bid for public contracts, keep credentials and methodology pages up to date, with no commitment the site cannot honour. This is not legal advice.

Questions to ask the provider

• Does the 301 map cover insights, author pages and downloadable PDFs?
• Do the three languages share the same URL structure?
• Who owns the domain, hosting and code at delivery?
• How long does it take to publish an article once the site is live?

When a Brussels agency is the better choice

If you expect in-person positioning workshops with every partner, a full rebrand or an editorial team producing your insights every month in three languages, a local agency at €25,000 or more is justified. The fixed grid fits when the offer and the brand are settled and the goal is a fast, trilingual, well-migrated site.

Mini case study

*Illustrative example, fictional firm.* Delvaux Merckx Conseil, a fictional 14-consultant firm near the European Quarter, has 180 insights, 12 author pages and 9 case studies. After sorting: 120 insights kept, 60 merged and redirected, 6 case studies kept with written consent. A Brussels agency quotes €36,000. The firm chooses Kolonell Premium at €8,200 for French, Dutch and English, and hands the Dutch review to a freelance translator, a third-party cost: 15,000 words x €0.12 = €1,800. Total: 8,200 + 1,800 = €10,000, or €26,000 less, with CRM as a separate line on quote.

FAQ

Should we migrate every insight?

Rarely. Keeping the most useful two thirds and redirecting the rest to related articles preserves most visibility, provided 100% of URLs have a destination.

Can we launch in French first?

Yes, but in Brussels a trilingual launch avoids 2 to 3 months of incomplete pages. Premium at €8,200 is the multilingual tier, with languages set in the quote.

How much preparation on our side?

Plan 2 to 4 weeks for the inventory, sorting insights and translations, before the 3 to 4 weeks of build.

Can our case studies name European institutions?

Only with written consent and in approved wording. Without it, an anonymised case of 300 to 500 words still persuades.

And after the 3 months of support?

Maintenance and hosting are then on quote, and you remain the owner of the site.
