The verdict in three sentences
For a London wealth management or investment firm, a serious redesign costs GBP 17,000 to 34,000 and ships in 10 to 14 weeks. Almost all of the premium over a standard corporate site comes from FCA compliance: every product page must be fair, clear and not misleading, give risks equal prominence and be approved by a compliance officer before going live. A site that skips these constraints is cheaper on day one, then exposes the firm to supervisory findings and repeated partial rebuilds.
What FCA rules mean for the website in practice
The FCA financial promotion rules (COBS 4), the Consumer Duty, PRIIPs and UCITS disclosure requirements do not mention technology, but they shape the site architecture. A financial promotion must be fair, clear and not misleading, show risks as prominently as benefits, and never display performance without the reference period and a past-performance warning. Since 2024, promotions must also be approved under section 21 by an authorised person.
| Regulatory requirement | What it means on the site | Budget impact (2026 estimate) |
|---|---|---|
| Balanced benefits and risks | Mandatory risk block in the fund page template, locked for editors | GBP 1,300 to 2,500 |
| Up-to-date KIDs and factsheets | Versioned document library, automatic link to the latest version per share class | GBP 2,500 to 5,000 |
| Regulated performance display | Tables fed by the administrator's data, disclaimers injected automatically | GBP 2,100 to 4,300 |
| Client categorisation | Retail / professional selection screen before accessing fund pages | GBP 1,000 to 2,100 |
| Compliance sign-off | Editorial workflow: draft, compliance review, timestamped publication | GBP 2,500 to 6,000 |
| Record keeping | Published versions archived for at least 5 years, timestamped PDF export | GBP 850 to 2,100 |
| SDR and SFDR labels | Sustainability label and disclosures displayed per fund | GBP 700 to 1,700 |
The most underestimated item is the approval workflow. Without it, marketing publishes a fund update, compliance discovers it afterwards and requests a correction. With a headless CMS such as Sanity or a custom back office, every change to a fund page stays in draft until compliance approves it, and the history serves as evidence during a supervisory review.
Budget and timeline for a 2026 redesign
Price gaps between London agencies mostly reflect the number of funds, the quality of input data and the design standard expected by a demanding private client base.
| Item | Site with 10 to 15 funds | Site with 30 to 50 funds |
|---|---|---|
| Scoping, compliance workshops, sitemap | GBP 2,100 | GBP 3,400 |
| Premium design, desktop and mobile mock-ups | GBP 4,300 | GBP 6,800 |
| Front end and CMS with workflow | GBP 6,000 | GBP 12,000 |
| Dynamic fund pages and KID library | GBP 3,000 | GBP 6,800 |
| Second language, SEO, accessibility | GBP 1,700 | GBP 3,400 |
| Testing, load tests, go-live | GBP 1,300 | GBP 1,700 |
| Total | GBP 18,400 | GBP 34,100 |
| Monthly maintenance | GBP 170 | GBP 340 |
The typical timeline is 10 to 14 weeks: 2 weeks of scoping with compliance, 3 weeks of design, 5 to 7 weeks of build, 1 to 2 weeks of compliance testing. Compliance testing is often the bottleneck: plan for a compliance team member to block 2 half-days a week during that phase.
Maintenance at GBP 170 to 340 per month covers security updates, uptime monitoring, daily backups and a few hours of changes. For a regulated firm, also require UK or EU hosting and an exit clause.
Mini case study
James, managing partner of a Mayfair wealth manager with GBP 1 bn under management and 22 share classes, is working with a 2017 site with no workflow. Every KID update currently needs the supplier at GBP 80 an hour, around 4 hours a month or GBP 3,840 a year, not counting the 2 corrections compliance requested last year.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
He chooses a redesign at GBP 24,000 with a document library and approval workflow, plus GBP 260 a month of maintenance. KIDs are now updated by file upload in 10 minutes by the operations team. If the new site generates just 3 extra meetings a year with professional investors each bringing GBP 1.7 m at 0.8% fees, that is about GBP 40,800 of recurring annual revenue, a payback of under one year.
FAQ
Does the FCA approve the website before launch?
No, the FCA does not pre-approve websites, but it can review financial promotions at any time. Responsibility lies with the firm and its section 21 approver, which is why a workflow that logs every approval for at least 5 years matters.
How long does integrating KIDs and factsheets take?
For 20 to 30 share classes, allow 3 to 5 days of development for the library and 1 to 2 days of document migration. Cost ranges from GBP 2,500 to 5,000 depending on whether documents arrive via an automated feed or manual upload.
Can performance be displayed in near real time?
Yes, via a daily feed from the administrator or depositary, for GBP 2,100 to 4,300. Period references and warnings must be injected automatically next to every figure.
Do we need a client categorisation screen?
As soon as you present funds reserved for professional investors, yes. This gate costs GBP 1,000 to 2,100 and should remember the choice without blocking search indexing of public pages.
What hosting suits a regulated firm?
UK or EU hosting with daily backups and a 99.9% uptime commitment. It costs GBP 35 to 130 per month, often included in maintenance.
