The verdict in three sentences
A family office in London does not need a website that attracts; it needs one that reassures without exposing anything: budget EUR 12,000 to 30,000 for the public site and EUR 6,000 to 15,000 for a private document portal with two-factor authentication. Domestic hosting, no third-party trackers at all and a flawless regulatory page matter more than design. Allow 8 to 10 weeks, two of which go to compliance sign-off.
What a family office website costs in 2026
Client families, their lawyers and partner private banks check the website before any meeting. They look for a clear identity, a verifiable regulatory status and a safe way to exchange documents. They are not looking for family names, assets under advice or a wall of team photos.
| Component | Price ex. VAT 2026 | Scope | Timeline |
|---|---|---|---|
| Restrained brochure site | EUR 12,000 to 18,000 | 6 to 10 pages, bilingual, editorial identity | 6 weeks |
| Premium institutional site | EUR 20,000 to 30,000 | 12 to 20 pages, custom typography, publications | 8 weeks |
| Private 2FA document portal | EUR 6,000 to 15,000 | File upload and sharing, access log, link expiry | 3 to 4 weeks |
| Certified domestic hosting | EUR 150 to 400 per month | ISO 27001 data centre, encrypted backups | Ongoing |
| Initial security audit | EUR 2,500 to 6,000 | Penetration test, CSP headers, access review | 1 to 2 weeks |
| Maintenance and monitoring | EUR 200 to 500 per month | Patches, certificate renewal, quarterly report | Ongoing |
The most underestimated item is the private portal. A link to a consumer file-sharing tool will not pass a serious compliance review: you need strong authentication, download traceability and automatic document purging.
Discretion level: what to show, what to hide
The right level depends on the model (single or multi-family), the regulatory status (FCA-authorised firm or exempt structure) and the business development strategy. The table below helps you choose.
| Discretion level | Public features | FCA and AML obligations to reflect | Indicative budget |
|---|---|---|---|
| Confidential (one page) | Name, address, contact by appointment | Legal notice, FCA register number if authorised | EUR 4,000 to 6,000 |
| Restrained | Philosophy, services, leadership without photos | Regulatory status, complaints policy, ombudsman | EUR 12,000 to 18,000 |
| Institutional | Publications, governance, partners | Conflicts of interest policy, ESG disclosures | EUR 20,000 to 30,000 |
| Institutional + private portal | All of the above + client portal | AML procedure, 5-year record retention, document KYC | EUR 26,000 to 45,000 |
| Active hiring | Careers page, encrypted applications | UK GDPR for candidates, 2-year retention | + EUR 2,000 to 4,000 |
These are 2026 ballpark figures from comparable projects. In every case: no US analytics tool, no advertising pixel, no font loaded from a third-party server. A consent-exempt, locally hosted analytics tool is enough.
Compliance checkpoints
Plan a review by your compliance officer or external adviser before launch. It covers wording (no performance promises, no "guaranteed returns"), consistency between stated status and actual activity, and the GDPR record of processing. The private portal must be documented in the AML procedure: who grants access, who revokes it, how long identity documents are stored.

Helen, CEO of a 14-person multi-family office in London, used to send quarterly statements by encrypted email to 38 families. Her team spent about 6 hours per quarter per relationship manager, so 4 managers x 6 h x 4 quarters = 96 hours a year. She invests EUR 22,000 in a restrained institutional site and EUR 11,000 in a 2FA private portal. Automated uploads cut that time by 70%, freeing 67 hours valued at EUR 120 an hour: EUR 8,040 a year. Above all, the custodian's annual audit no longer flags untracked transmissions, avoiding remediation work estimated at EUR 15,000.
FAQ
What budget should a London family office plan for its website?
EUR 12,000 to 30,000 for the public site, plus EUR 6,000 to 15,000 for a private portal. A complete, audited project usually lands between EUR 26,000 and 40,000.
Should the site be hosted locally?
It is strongly recommended for the private portal, which holds personal and wealth data. Domestic hosting costs EUR 150 to 400 a month and simplifies the GDPR review and custodian bank questionnaires.
Can you measure traffic without third-party trackers?
Yes, with a consent-exempt, locally hosted analytics tool. You lose demographic data, but a family office rarely receives more than 300 to 800 visits a month.
Does two-factor authentication put families off?
Rarely, if it relies on a mobile app or a hardware key. Allow 10 to 15 minutes of onboarding per user when the account is opened.
How long from signature to launch?
Eight to 10 weeks, including 2 weeks of compliance review. The private portal can follow 3 to 4 weeks after the public site.
