Website redesign for a wealth management firm or family office in London: budget, timeline and risks (2026)

The verdict in three sentences

For a wealth management firm or family office in London, a redesign turns less on design than on two risks: losing hard-won search visibility for lack of a 301 redirect map, and publishing content that compliance has not signed off under the FCA financial promotion rules. Budgets run roughly from 20 000 to 90 000 GBP with a London agency, against 2 300, 3 900 or 6 900 GBP fixed with Kolonell, delivered in 3 to 4 weeks once content is approved. Above all, plan for your compliance team's review time: that is what sets the real schedule.

Which signals show a redesign is due?

A wealth management website ages in a specific way: it does not break, it loses trust. The most common signals in London: a team page still listing departed partners, an investment approach section written before the Consumer Duty came into force, a cookie banner that drops trackers before any consent, a contact form sending sensitive data by plain email, a site that is unreadable on a phone while your international clients check it between flights, and no French or Arabic version for clients from Geneva, Paris or the Gulf.

If three of these signals are present, a redesign usually costs less than a string of patches.

What budget should you plan for a London redesign?

These ranges are based on public price pages of UK agencies, minimum project sizes shown on Clutch.co profiles of London agencies and day rates published by freelancers on Malt and Upwork. Every Kolonell tier includes a project manager reachable in your time zone (the team is based in Dakar, on GMT, so the same time as London in winter and one hour behind in summer), native English or French copywriting, delivery in 3 to 4 weeks and 3 months of support after launch. A link to your existing client login is simple to add; the portal itself stays quoted on request. Details on the international website offer.

How long does a redesign really take?

The compliance sign-off phase depends on no provider: your compliance officer runs it. Start it as soon as the site structure is fixed.

What are the main risks and how do you mitigate them?

Search risk. Export every URL from Google Search Console and a crawler, map each old page to a new one with a 301 redirect, keep the titles of pages that bring visits, then watch for errors in Search Console for 8 weeks.

Compliance risk. If your firm is FCA-authorised, a page presenting your services can be a financial promotion: it must be fair, clear and not misleading, and past performance should not be published without the required warnings and internal sign-off. The Consumer Duty, in force since 31 July 2023, requires communications with retail clients to be understandable. An unauthorised single family office should stay cautious with any public communication. UK GDPR, the Data Protection Act 2018 and PECR require consent before non-essential cookies and an accurate privacy notice. Aim for WCAG 2.2 AA for accessibility. This is not legal advice.

Discretion risk. No client names, no logos, no case studies without written consent.

When is a London agency the better option?

If your leadership wants in-person workshops in Mayfair, a photo shoot of the team and offices, a brand film or a full identity overhaul, a local agency is better placed: Kolonell does no on-site meetings and no shoots. The same goes if the redesign includes a client portal with strong authentication and integration with your portfolio management system within 3 months: a specialist local provider, with its insurance and outsourcing procedures, will simplify your vendor due diligence.

Which questions should you ask every provider?

• Who produces the URL inventory and redirect map, and who tests it?
• How many compliance review cycles does the schedule allow?
• Where is form data hosted, and under which data processing agreement?
• Are the domain, hosting and code in our name?
• What does a content change cost after the support period?

Mini case study

Illustrative example. Antoine L., COO of a French multi-family office based in London, runs a 2014 site with 140 URLs. A specialist agency quotes 48 000 GBP over 16 weeks. He picks Kolonell Premium at 6 900 GBP for a bilingual French and English version, and hires a London photographer for team portraits at 1 500 GBP: 8 400 GBP in total, a 39 600 GBP gap. Risk hypothesis: the site generates 6 qualified inquiries a month from search; a poor redirect map losing half of them for 3 months would cost 9 inquiries. The 301 map is therefore tested line by line before go-live.

FAQ

How long should compliance allow to review the site?

Allow 3 to 6 weeks for 15 to 25 pages, with two review cycles. That period comes before the 3 to 4 weeks of build.

Is the client portal included in Premium at 6 900 GBP?

No. Premium covers the bilingual public site; a link to your existing portal is possible, the portal itself is quoted on request.

Will we lose traffic after the redesign?

A temporary dip over 2 to 6 weeks is common, even with a good 301 map. It stays limited if every old URL redirects to an equivalent page.

Can we publish our historical performance?

Only after compliance sign-off and with the warnings required by the applicable rules. Many London firms prefer to present their method rather than figures.

Is the time difference an issue?

No: London and Dakar share the same time in winter and are one hour apart in summer, almost a full common working day.
