The verdict in three sentences
Redesigning a bank's institutional website in Nairobi costs between 15 and 50 million FCFA in 2026, a spread driven by security, content governance and language count. The project runs 4 to 8 months with a dedicated project manager, sprints and weekly reviews, then a maintenance contract of 3 to 8 million FCFA/year. For a bank, the site is not a brochure but a compliance and trust asset: the budget is justified by reputational risk, not page count.
The specific institutional requirements
A banking site has nothing to do with a brochure site. Regulatory and security requirements shape the whole budget. Here is what sets a premium redesign apart.
| Requirement | What it implies | Budget impact |
|---|---|---|
| Content governance | Multi-level approval workflow, headless CMS | +2-5 M FCFA |
| Security | CSP headers, audit, WAF, advanced SSL | +3-6 M FCFA |
| Multilingual | EN + FR + sometimes Arabic (RTL) | +2-4 M FCFA |
| WCAG 2.1 AA accessibility | Mandatory audit and remediation | +1.5-3 M FCFA |
| Compliance | GDPR + local data protection law | +1-2 M FCFA |
| SLA & monitoring | 99.9% uptime, backup, 24/7 supervision | included in maintenance |
Security and governance alone represent 40 to 50% of the budget. That is the price of compliance for a regulated institution.
Project tiers and milestones
A banking redesign runs in milestone-based phases, each validated before payment. Here is the reference breakdown for 2026.
| Tier | Scope | Price FCFA | Timeline |
|---|---|---|---|
| Standard | 20-30 pages, CMS, EN/FR, hardened security | 15,000,000 - 25,000,000 | 4-5 months |
| Premium | + ERP/CRM, client portal, 3 languages, security audit | 26,000,000 - 40,000,000 | 6-7 months |
| Group | + multi-site subsidiaries, design system, intranet | 41,000,000 - 50,000,000+ | 7-8 months |
Key milestones: framing and architecture (month 1), design system and mockups (month 2), development and CMS integration (months 3-5), security and accessibility audits (month 6), acceptance and go-live (months 7-8). Each milestone gates the next.
Mini case study
Ms. Kone, communications director of a banking group in Nairobi, is leading the corporate site redesign. She selects the Premium tier at 34,000,000 FCFA over 7 months: editorial-workflow CMS, investor portal, three languages, security audit included. She adds a maintenance contract of 5,000,000 FCFA/year. The value case: the current site generates 40% of client complaints about difficulty finding pricing information. By halving that rate, she estimates saving 1,200 hours of client-service handling over the year, roughly 9,000,000 FCFA of avoided cost, not counting the reputational gain.

FAQ
Why does a banking redesign cost 15 to 50 million FCFA?
Because security, multi-level content governance, WCAG accessibility and regulatory compliance make up half the budget. A banking site is an audited compliance asset, not a brochure.
How long does the project take in 2026?
From 4 months for a Standard tier to 8 months for a multi-subsidiary Group project. Security-audit and acceptance phases cannot be compressed without regulatory risk.
What is the maintenance contract and why is it mandatory?
Application maintenance covers security, updates, 24/7 monitoring and enhancements. For a bank, between 3 and 8 million FCFA/year, it guarantees 99.9% uptime and incident responsiveness.
Do banks need a headless CMS?
Yes, when several departments publish content with approval. A headless CMS enables multi-level workflow, publication auditing and multi-channel delivery, essential to governance.
Does Arabic multilingual support add much cost?
RTL (right-to-left) support adds 2 to 4 million FCFA because it affects layout, components and testing. Plan for it at framing if diaspora or regional clients justify it.
