The verdict in three sentences
A private clinic website in London costs between 8,000 and 20,000 EUR in 2026, depending on the number of specialties and the level of online booking. The line that really moves the budget is not the design but certified health-data hosting and health-data compliance, mandatory as soon as a form touches patient data. Expect 6 to 10 weeks from brief to launch.
What makes up the budget
A clinic does not buy a website: it buys trust and a reliable booking channel. Reassuring design (real photos of the technical platform, practitioner profiles, reviews) is one part, but half the budget goes into functional modules and compliance.
| Line item | 2026 range (EUR) | Comment |
|---|---|---|
| Design + build (8-12 pages) | 4,500 - 8,000 | Brand, specialty pages, practitioners |
| Additional specialty pages | 350 - 600 / page | Beyond 6 specialties |
| Booking via third-party integration | 800 - 1,800 | Widget + funnel |
| Custom booking system | 4,000 - 9,000 | Own calendar, SMS reminders |
| Health-data compliance + notices | 1,200 - 3,000 | Register, consents, DPO |
| Local SEO London | 1,500 - 3,500 | Google profile, area pages |
| Project total | 8,000 - 20,000 | Depending on options |
Third-party booking or custom booking
The question comes up in every quote. A third-party widget is fast to integrate and already adopted by patients, but it locks you into its ecosystem and fees. A custom calendar costs more upfront but makes you the data owner and removes the dependency.
| Criterion | Third-party widget | Custom calendar |
|---|---|---|
| Upfront cost | 800 - 1,800 EUR | 4,000 - 9,000 EUR |
| Recurring cost | Per-practitioner subscription | 0 (excl. maintenance) |
| Data ownership | No | Yes |
| SMS reminders | Included | 0.08 EUR / SMS |
| Integration time | 3 - 5 days | 3 - 5 weeks |
| Health-data hosting required | No (on their side) | Yes (200-600 EUR/month) |

Dr Fontaine runs an ophthalmology clinic in central London with 5 practitioners. She hesitates between a third-party widget and a custom calendar. Custom calendar budget: 6,500 EUR + health-data hosting at 350 EUR/month, i.e. 4,200 EUR/year. By comparison, the third-party tool costs 129 EUR/month per practitioner, i.e. 7,740 EUR/year for 5 practitioners. From year 2, the custom build pays off: over 3 years, custom = 6,500 + 12,600 = 19,100 EUR, versus third-party = 23,220 EUR. The clinic saves 4,120 EUR over 3 years while keeping control of its patient data.
FAQ
Is health-data hosting really mandatory? Yes, as soon as your site collects or stores identifying health data (custom booking, pre-consultation form). Expect 200 to 600 EUR/month depending on the certifier. If you use a third-party booking tool, the health-data hosting is on their side.
How long to go live? Between 6 and 10 weeks. Design takes 3 weeks, development 3 to 5, and compliance testing 1 to 2 weeks. Well-written specialty pages are often the limiting factor.
Does local SEO really matter for a clinic? Enormously. 78% of patients search "ophthalmologist + area" on Google before calling. A strategy of pages per specialty and London area can triple inbound booking requests within 6 months.
What is the annual maintenance budget? Expect 1,200 to 3,600 EUR/year for security updates, backups and small changes, on top of health-data hosting. Security is not optional on a health website.
Can we start with a third-party tool then migrate? Yes, and it is a prudent strategy. You launch with the widget, validate booking volume, then switch to a custom calendar once ROI is proven. The architecture just needs to anticipate that switch from the start.
