The verdict in three sentences
For an aesthetic and cosmetic clinic in Brussels, a 2026 redesign typically costs €12,000 to €40,000 with a local agency, against €2,700 (Starter), €4,500 (Growth) or €8,200 (Premium) on Kolonell's fixed grid. The main risk is not technical: it is a site whose copy breaches Belgium's rules on advertising aesthetic medicine, with promised results or before-and-after photos. With a compliance review, a 301 redirect map for treatment pages and online booking priced separately, the site goes live in 3 to 4 weeks once content is approved.
Signals that a redesign is due
| Signal | What you notice | Impact |
|---|---|---|
| Old promotional copy | Phrases like 'guaranteed results' or before-and-after galleries | Compliance risk |
| Only one polished language | Dutch or English is a machine translation | Lost European and Dutch-speaking patients |
| Thin treatment pages | 150 words per procedure, nothing on the prior consultation | Little qualified traffic |
| Booking by email | Back-and-forth, lost slots | Admin workload |
| Outdated cookie banner | No granular consent | GDPR exposure |
| Slow on mobile | More than 4 seconds to load | Visitors leave before getting in touch |
A clinic in Ixelles, Uccle, on Avenue Louise or in Woluwe that ticks three rows of this table is better off redesigning than fixing page by page.

What timeline, and which steps?
- Days 1 to 4: URL inventory, Search Console export, 301 redirect map for every treatment page that receives traffic.
- Days 5 to 10: treatment pages written to inform (what happens, prior consultation, general contraindications), with no promised results.
- Days 11 to 18: design, build, minimal forms.
- Days 19 to 22: language versions, compliance review by the responsible doctor.
- Days 23 to 25: QA, switch, monitoring.
Allow one to two extra weeks if the medical review of all three languages is not scheduled.
Which risks should you watch?
- Advertising: in Belgium, a 2013 law on aesthetic medicine strictly regulates advertising for these procedures. The site should stay informative: no promised results, no before-and-after photos, no aggressive promotions. Have your responsible doctor approve it.
- Search rankings: every treatment page that receives traffic needs a 301 redirect to its equivalent; 30 days of Search Console monitoring.
- Health data: the contact form is limited to name, contact, treatment of interest and preferred slot; no detailed medical data in an open form. GDPR and the Data Protection Authority (APD/GBA).
- Languages: a machine-translated Dutch page can contradict the French one; a review by a freelance translator (third-party cost) reduces that risk.
- Booking: connecting to your calendar is a separate project, quoted separately, with a fallback form.
- Downtime: switch on a Sunday evening, TTL lowered 48 hours before.
This is not legal advice.
When should you pick a Brussels agency?
A local agency is the better fit if you are launching a new visual identity with a photo shoot in the clinic at the same time, a custom patient area, or want in-person workshops with the whole medical team. Kolonell suits an informative, multilingual redesign with a clear scope. Questions to ask: who checks the copy for compliance? Can treatment pages be edited without a developer? Does the domain stay in your name? What does maintenance cost after the included period?

FAQ
Can we keep our before-and-after photos?
Advertising for aesthetic procedures is strictly regulated in Belgium; the prudent choice is to remove them from the site. A 1 to 2 day compliance review is planned before launch.
How many languages should a Brussels clinic plan for?
Often three: French, Dutch and English. The €8,200 Premium tier covers several languages, set in the quote.
Is booking included in the €4,500 Growth tier?
No. Growth includes an enquiry form; booking connected to your calendar is quoted separately.
How long does the redesign take?
Around 25 working days, so 3 to 4 weeks once content is approved. Allow 1 to 2 extra weeks for the multilingual medical review.
Will we lose traffic?
A temporary dip of 2 to 6 weeks is possible. A 301 map covering every treatment page sharply limits the risk.
