The verdict in three sentences
For a group dental practice in Utrecht, the right question is the three-year cost: patching an ageing site often costs as much as a redesign, without fixing the English version or the fees page. At Kolonell a redesign costs EUR 4,500 (Growth) or EUR 8,200 (Premium, the multilingual tier, languages set in the quote), against a 2026 ballpark of EUR 8,000 to 25,000 at a local agency. The project is won or lost on the URL inventory, the 301 redirect map and the practice's review of content before go-live.
Patch or redesign: which signals decide it?
Utrecht combines families (Leidsche Rijn, Oog in Al, Wittevrouwen), students and international residents arriving through the central station. A site built seven or eight years ago for only one of these groups soon shows its limits.
| Signal | One-off fix (2026 ballpark) | Solved by a redesign? |
|---|---|---|
| Theme not built for mobile | EUR 1,500 to 3,000, often partial | Yes |
| Fees page out of line with current NZa codes | EUR 300 to 800 per update | Yes, with an easy-to-update template |
| English version missing or incomplete | EUR 1,500 to 4,000 | Yes, Premium tier |
| Team pages without BIG number or clear role | EUR 400 to 1,000 | Yes |
| Form asking for medical history | EUR 300 to 600 | Yes, minimal form |
| Outdated plugins and security holes | EUR 150 to 300 per month | Yes, new foundation |
Once three or more rows apply, the sum of fixes usually exceeds the price of a Growth redesign.
What does a redesign cost over three years?
The table compares upfront cost with market maintenance over 36 months. Maintenance amounts are market assumptions, not Kolonell prices: at Kolonell the first 3 months of support are included and maintenance afterwards is on quote.
| Scenario | Upfront | Maintenance over the period (market assumption) | 3-year total |
|---|---|---|---|
| Patch the old site | EUR 2,500 | 36 x 150 = EUR 5,400, plus 2 x EUR 1,500 yearly fixes | EUR 10,900 |
| Local freelancer | EUR 6,000 | 36 x 100 = EUR 3,600 | EUR 9,600 |
| Local agency in Utrecht | EUR 15,000 | 36 x 150 = EUR 5,400 | EUR 20,400 |
| Kolonell Starter | EUR 2,700 | 33 x 100 = EUR 3,300 (market assumption; Kolonell maintenance after the 3 included months on quote) | EUR 6,000 |
| Kolonell Growth | EUR 4,500 | 33 x 100 = EUR 3,300 (market assumption; Kolonell maintenance after the 3 included months on quote) | EUR 7,800 |
| Kolonell Premium | EUR 8,200 | 33 x 100 = EUR 3,300 (market assumption; Kolonell maintenance after the 3 included months on quote) | EUR 11,500 |
Every tier includes a project manager reachable in your time zone, native English or French copywriting, delivery in 3 to 4 weeks and 3 months of support. Native Dutch copy can go to an independent translator or copywriter, billed as a third-party cost. Tier details are on the international offer page.
What timeline suits a group practice?
A practice with four to six clinicians has a busier sign-off path than a solo practice: approval goes through several partners. Kolonell timings start once content is ready.
| Week | Kolonell side | Practice side |
|---|---|---|
| 1 | URL inventory, Search Console export, 301 map | List of clinicians, BIG numbers, opening hours |
| 2 | Mockups for home, treatment page, fees page | Sign-off by one lead partner |
| 2 to 3 | Treatment pages and fees page migrated | Review of treatment copy |
| 3 | English version (Premium) | Compliance review of marketing content |
| 4 | Go-live, 301 tests, sitemap submitted | Google Business Profile updated |
| 5 to 12 | 404 monitoring in Search Console | Front desk reports broken links patients mention |
Avoid switching over in your busiest weeks, for example the back-to-school period if your check-up calendar fills up then.
Which risks should you watch during migration?
- Ranking treatment and fees pages: every URL that receives clicks keeps a 301 to its closest equivalent, never to the home page by default.
- Integrations: online booking, the patient portal, recall reminders and the link to the practice management software stay embedded or linked, priced on quote, never rebuilt.
- Downtime: DNS switch planned on a quiet day, with TTL lowered 48 hours ahead.
- Compliance: no superlatives or promised outcomes, specialist titles (orthodontist, oral and maxillofacial surgeon) only where they appear in the BIG register, before/after photos and reviews only where the rules allow and with consent. KNMT guidance can serve as a reference point.
- Health data: the public form collects name, contact details and reason for visit only. Tracking pixels on treatment pages are reviewed with the practice's privacy adviser under the GDPR (AVG) and the positions of the Autoriteit Persoonsgegevens. This is not legal advice.
Questions to ask any provider: how many URLs does the 301 map cover, who tests the redirects, who updates the fees page when NZa codes change, and what does support cost after the included period?
When is a local Utrecht agency the better choice?
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
If you want native Dutch copy written by the agency itself, regular photo shoots at the practice, or someone who attends every partners' meeting in person, a local agency is justified, even at EUR 15,000 or more.
Mini case study
Illustrative example: the fictional Lindeboom Dental, a group practice in Leidsche Rijn with five dentists and three hygienists. The old site has 52 URLs, including 14 treatment and fees pages that receive clicks.
Option A, patch: EUR 3,000 of fixes, then 36 x EUR 120 maintenance (market assumption) = EUR 4,320, plus 2 x EUR 2,000 yearly fixes = EUR 4,000. Total EUR 11,320, still without an English version.
Option B, Premium (Dutch and English set in the quote): EUR 8,200, plus 33 x EUR 120 maintenance (market assumption; Kolonell maintenance after the 3 included months on quote) = EUR 3,960. Total EUR 12,160.
Gap: EUR 840 over three years, for a new site in the languages set in the quote and a 301 map covering all 52 URLs. Online booking stays priced separately.
FAQ
How much does a dental practice website redesign cost in Utrecht?
2026 ballpark: EUR 8,000 to 25,000 at a local agency, EUR 3,000 to 8,000 with a freelancer. At Kolonell, EUR 2,700 (Starter), EUR 4,500 (Growth) or EUR 8,200 (Premium).
How long does the project take?
3 to 4 weeks with Kolonell once content is ready, then 8 weeks of 404 monitoring. Sign-off between partners remains the main cause of delay.
Should we keep the fees page URLs?
Yes, if they receive clicks or links. One 301 per URL, tested on go-live day.
Is online booking included?
No, it stays on quote, embedded or linked from your current tool. A EUR 4,500 Growth site can host it without rebuilding it.
What does maintenance cost after delivery?
The first 3 months of support are included; after that it is on quote. The EUR 100 to 150 per month used here are market assumptions.
