The verdict in three sentences
A prospective member of a concierge medicine or longevity clinic in Amsterdam often pays several thousand euros a year: they judge your medical credibility on the website before asking for a first appointment. A redesign costs between 12,000 and 90,000 EUR at a local agency in 2026, against a Kolonell fixed grid of 2,700 EUR (Starter), 4,500 EUR (Growth) or 8,200 EUR (Premium, the multilingual tier). The main risk is the migration rather than the budget: lost search visibility, unsupported health claims and health data collected without need.
Signs your site is hurting your credibility
A longevity clinic's clientele in Amsterdam includes executives, expatriates and international families. They compare your site with private clinics in London or Zurich. They want to know who the doctors are, what the membership includes, what is evidence-based and what is not.
| Sign on the current site | What a prospective member concludes | Expected fix |
|---|---|---|
| Doctors listed without BIG registration or background | The team cannot be verified | Doctor profiles with registration and specialties |
| Claims such as 'live longer' | Marketing rather than medicine | Factual wording, references to protocols |
| Membership fee missing or vague | Hidden costs ahead | Membership range and what each plan includes |
| Form asking for medical history up front | Sensitive data collected too early | Minimal form, medical file in a secure portal |
| Machine-translated English version | International clients neglected | Native English, carefully written Dutch |
| Over 4 seconds to load on mobile | A dated organisation | Light pages, optimised images |
In the Netherlands, healthcare professionals appear on the BIG register, the Health and Youth Care Inspectorate (IGJ) supervises quality of care, and the GDPR (AVG in Dutch) is enforced by the Autoriteit Persoonsgegevens. Health claims must remain evidence-based. This is not legal advice: have medical content reviewed by your medical director and your counsel.
Budget: Amsterdam agencies vs the Kolonell grid
| Option | 2026 budget | Typical timeline | Note |
|---|---|---|---|
| Local freelancer | 3,000 to 10,000 EUR | 6 to 10 weeks | Depends on one person |
| Mid-market Amsterdam agency | 12,000 to 35,000 EUR | 8 to 14 weeks | Custom design, Dutch and English |
| High-end healthcare agency | 40,000 to 90,000 EUR | 12 to 20 weeks | Brand strategy, workshops, photography |
| Kolonell Starter | 2,700 EUR | 3 to 4 weeks | Restrained site, content ready |
| Kolonell Growth | 4,500 EUR | 3 to 4 weeks | Richer editorial structure |
| Kolonell Premium | 8,200 EUR | 4 to 6 weeks | Multilingual tier, languages set in the quote |
Local ranges: 2026 ballpark from typical Amsterdam agency quotes. Every Kolonell tier includes a project manager reachable in your time zone, native English or French copywriting and 3 months of support. The member portal, connected booking and integrations with your practice software are on quote. Details on the international offer.
Timeline and risks of a redesign
Once content is ready and approved by the medical director, a redesign runs in four phases: inventory and architecture (week 1), design and copywriting (weeks 2 and 3), build and compliance review (weeks 3 and 4, up to 6 for Premium), launch and monitoring.
| Risk | Consequence | Mitigation |
|---|---|---|
| Lost search visibility | Fewer enquiries for months | URL inventory, 301 redirect map, Search Console monitoring |
| Incomplete content migration | Protocol or FAQ pages lost | Page-by-page mapping sheet |
| Unreviewed medical claims | Regulatory and reputational exposure | Medical director review before launch |
| Health data collected through forms | High GDPR risk | Minimal form, secure portal on quote |
| Downtime | Missed appointments | Planned switchover outside opening hours |
| Forgotten integrations | Calendar or payment failures | List of integrations priced on quote from the start |
When a local agency is the better choice
If you want a video shoot on your premises, in-person brand workshops or a complex integration with a Dutch electronic patient record, an Amsterdam agency is a better fit. The same applies if your main content must be written in Dutch by a native medical writer. For a restrained, fast and credible site aimed at an international clientele, the fixed grid is often enough. Ask every provider: who reviews the medical claims, how redirects are tested, and where form data is hosted.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Illustrative example: Vondel Longevity Clinic, a fictional Amsterdam clinic, offers an annual membership at 6,000 EUR. Its current site has 140 indexed URLs. It compares a high-end agency at 45,000 EUR with the Kolonell Premium tier at 8,200 EUR, plus 2,500 EUR of Dutch translation by a third party and 1,800 EUR of photography, so 8,200 + 2,500 + 1,800 = 12,500 EUR.
The gap is 45,000 minus 12,500 = 32,500 EUR. With a 6,000 EUR membership, 3 new members bring 18,000 EUR, more than the total cost of the Premium option. The redirect map covers all 140 URLs before the switchover.
FAQ
How much does a longevity clinic website redesign cost in Amsterdam?
From 12,000 to 90,000 EUR at a local agency, 2026 ballpark. At Kolonell, the fixed grid runs from 2,700 to 8,200 EUR, with the member portal and integrations on quote.
Can we show the membership price?
Yes, and it is often appreciated as a sign of transparency: a range, for example 4,000 to 9,000 EUR a year depending on the plan, with exactly what each plan includes. Check the wording with your counsel.
How do we avoid losing search visibility?
By listing every URL, redirecting each old page with a 301 and monitoring Search Console for at least 8 weeks. A temporary dip of a few weeks remains common.
Are Dutch and English included?
Premium is the multilingual tier, with languages set in the quote. Professional translation by a third party is priced separately, about 2,500 EUR in our example.
What does maintenance cost after the 3 months of support?
It is priced on quote. On the market, allow 150 to 500 EUR a month for a site of this size, market assumption.
