The verdict in three sentences
For a wealth management firm, trust company or family office in St Helier, Jersey, a website from an island agency or a London studio usually costs 8 000 to 30 000+ GBP in 2026 (ballpark), with a monthly retainer common on top. Kolonell delivers a discreet, compliance-ready site at 2 300, 3 900 or 6 900 GBP, fixed in writing, with native English or French copy and a bilingual EN/FR option from Premium. On an island where everyone in finance knows everyone, the website must above all look serious, quiet and accurate, and that does not require a 30 000 GBP budget.
Why do Jersey quotes sit at the top of the range?
St Helier is a finance centre with a small local supplier market. A handful of island agencies serve banks, trust companies, law firms and fund administrators, and many firms also use London agencies, so prices follow island costs and London benchmarks rather than regional UK rates. The ranges below are a prudent 2026 ballpark based on public agency rate cards, Clutch.co profiles with minimum project sizes and freelance platform rates; they vary with scope and are not quotes from any named firm.
| Option | Build price (2026 ballpark) | Typical delay | Usually included | Typical after-launch model |
|---|---|---|---|---|
| London agency with private wealth clients | 15 000 to 40 000+ GBP | 12 to 16 weeks | Brand workshops, custom design, CMS | Monthly retainer |
| Jersey-based agency | 8 000 to 30 000 GBP | 8 to 14 weeks | Design, CMS, local meetings | Retainer or support hours |
| Freelancer (island or remote) | 2 500 to 8 000 GBP | 4 to 10 weeks | Theme-based build | Ad hoc |
| Kolonell Starter | 2 300 GBP | 3 to 4 weeks | 5 custom pages, native copy, contact form, video call booking | 3 months of support |
| Kolonell Growth | 3 900 GBP | 3 to 4 weeks | 10+ pages, insights blog, analytics, full SEO setup | 3 months of support |
| Kolonell Premium | 6 900 GBP | 4 to 6 weeks, written schedule at kickoff | Unlimited pages, bilingual EN/FR or more languages, content strategy | 6 months of support |

What must a Jersey trust, wealth or family office site show?
Jersey firms often serve international families: UK, Middle East, Africa, Asia and continental Europe. Prospects and their lawyers check the website after an introduction, and they look for structure, regulation and people, not marketing slogans.
- Discretion: no client names, no performance figures, no assets under administration unless the firm already publishes them.
- Regulated status and governance: board, directors, key persons, ownership, with qualifications as held. Rules on financial promotion and advertising apply depending on the licence held under the Jersey Financial Services Commission (JFSC) framework, and your compliance officer must validate every page.
- Services described plainly: wealth structuring, trust and company administration, family office services, succession, philanthropy and foundations, investment advisory where licensed. No investment advice and no return figures.
- Data protection: Jersey has its own law, the Data Protection (Jersey) Law 2018, overseen by the Jersey Office of the Information Commissioner. Privacy notice, cookie consent and a secure enquiry form are the baseline.
- Languages: English first; French is relevant for families from France, Belgium, Switzerland or francophone Africa and is available from Premium. Arabic, Mandarin or other languages are supplied by you or quoted separately.
- Single family office: an office that takes no outside clients may want only a short discreet site for counterparties, banks and recruits, which fits Starter.
A client portal, document vault or investor reporting area is a custom application, always quoted on request and never in the grid. This is general information, not legal or regulatory advice.

Illustrative example, fictitious firm: Richard is a director of a small multi-family office in St Helier with English and French-speaking families. An island agency quotes 18 000 GBP for an English site, 3 000 GBP more for French, and 200 GBP a month. Three years: 18 000 + 3 000 + (200 x 36) = 28 200 GBP. Kolonell Premium costs 6 900 GBP with both languages and 6 months of support; assuming the same 200 GBP monthly budget for the remaining 30 months (6 000 GBP, maintenance being quoted), the total is about 12 900 GBP, roughly 15 300 GBP less.
