The verdict in three sentences
A new website for a cosmetic dentistry practice in London costs GBP 8,000 to 20,000 at a specialist dental agency in 2026 and up to GBP 50,000 at a premium agency, as a ballpark. Kolonell's fixed grid sits at GBP 2,300 (Starter), GBP 3,900 (Growth) and GBP 6,900 (Premium), with a project manager reachable on London time and native English copywriting. The real cost lies in the extras: photography, compliance review, online booking and three years of maintenance.
What does a dental website really cost in London?
The figures below reflect typical agency quotes and public agency rate pages, as a 2026 ballpark, for a 12 to 25 page site.
| Provider | Build price (2026 ballpark) | Usual timeline | What you typically get |
|---|---|---|---|
| London freelancer | GBP 3,000 to 8,000 | 4 to 8 weeks | Design and build, content supplied by the practice |
| Dental marketing agency | GBP 8,000 to 20,000 | 6 to 12 weeks | Proven templates, often tied to a marketing subscription |
| Premium central London agency | GBP 20,000 to 50,000 | 3 to 5 months | Art direction, filming, brand strategy |
| Kolonell Starter | GBP 2,300 | 3 to 4 weeks | Compact site for one dentist and a few treatments |
| Kolonell Growth | GBP 3,900 | 3 to 4 weeks | Treatment pages, team, reviews, blog |
| Kolonell Premium | GBP 6,900 | 4 to 6 weeks | Multilingual version, languages set in the quote |
Every Kolonell tier includes a project manager reachable in your time zone, native English or French copywriting, the stated delivery time and 3 months of support. Integrations (practice management software, booking, finance calculator) and patient areas are quoted separately. Details on the international offer page.
What the site must prove to a London patient
A patient considering veneers or implants compares three to five practices. They want to know who will treat them, with which qualification, at what price and with what aftercare.
| Page | What it must show | Watch point |
|---|---|---|
| Team | Dentists with their General Dental Council registration number | Exact titles, no unrecognised 'specialist' claims |
| Veneers and composite bonding | Indications, steps, indicative lifespan | No promise of results |
| Implants | Process, number of appointments, alternatives | Risks and contraindications explained |
| Aligners | Indicative duration, follow-up, conditions | Separate assessment from treatment |
| Fees | 'From' ranges, consultation fee | Prices kept current and dated |
| Finance | Instalment options | Financial promotions fall within the FCA framework |
| Reviews and cases | Verified reviews, photos with written consent | ASA and CAP Code rules on advertising |
| Booking | Short form or online tool | Health data kept to the strict minimum |
The UK framework matters too: UK GDPR, the Data Protection Act 2018 and ICO oversight for data, PECR for cookies and marketing email, and the Equality Act 2010 with a WCAG 2.2 AA target for accessibility. This is not legal advice: have your treatment and fee pages reviewed before going live.
Hidden costs and the three-year total
The build price is only part of the picture. Here is a 36-month total for a 15 page site, with market assumptions clearly labelled.
| Item | Dental marketing agency | Kolonell Growth |
|---|---|---|
| Build | GBP 14,000 | GBP 3,900 |
| Team and practice photography (third party) | GBP 1,500 | GBP 1,500 |
| Compliance review by the practice | 6 internal hours | 6 internal hours |
| Booking and integrations | Often bundled in the subscription | On quote |
| Maintenance after delivery | Market assumption: GBP 250 per month for 36 months, or GBP 9,000 | 3 months included, then on quote |
| Translations (third party) | GBP 0.10 to 0.20 per word, market assumption | Multilingual copy in Premium, languages in the quote |
On the agency assumption, the total reaches 14,000 + 1,500 + 9,000 = GBP 24,500 over three years. On the Kolonell side the known part is 3,900 + 1,500 = GBP 5,400, plus maintenance on quote after 3 months.
When a London agency is still the better choice
A local agency makes sense if you want video filmed in the practice, photo shoots every quarter, or a single provider that also runs your paid campaigns and social media day to day. It also makes sense if your group requires software or a supplier that is already approved.

Questions to ask any provider: who owns the site and the domain at the end of the contract? Does the price include writing the treatment pages? Who checks GDC references and advertising rules? How is booking form data stored? What does leaving the subscription cost?
Mini case study
Illustrative example: 'Marylebone Smile Studio', three dentists, veneers, aligners and implants. A dental marketing agency proposes GBP 14,000 for the build and GBP 250 a month for maintenance. The practice chooses Kolonell Growth at GBP 3,900, adds GBP 1,500 of photography and has the integration of its booking tool quoted separately. Difference on build and photography: 15,500 minus 5,400, or GBP 10,100, to be weighed against the integration quote and the negotiated maintenance.
FAQ
What budget should a London cosmetic dentistry practice plan for its website?
As a 2026 ballpark, GBP 8,000 to 20,000 at a specialist dental agency and GBP 20,000 to 50,000 at a premium agency. Kolonell offers GBP 2,300, 3,900 or 6,900 depending on the tier.
Can we show before-and-after photos?
It is common, with the patient's written consent and in line with ASA advertising rules and GDC principles. Avoid retouching and give the treatment context.
Should we publish our fees?
