Financial services websites in Johannesburg have a compliance layer that eliminates most general web agencies from the shortlist: Section 21 FSMA financial promotions approval, mandatory FSCS protection wording, and real-time rate or calculator components that require backend API architecture rather than a JavaScript widget. Most Johannesburg agencies will write 'fintech' in their sector list but have never shipped a live FCA-regulated product-the agencies on this list have, or have the specific compliance knowledge to manage the delivery without recurring legal rework.

Full Johannesburg rankingCompliance note
Financial promotions communicated on websites regulated under FSMA 2000 must be approved by an FCA-authorised person (Section 21)-this is a criminal liability issue, not an optional compliance step.

Buyer's Checklist
These are the questions and checks that separate fintech & finance specialists from general web agencies who will list your sector on their homepage after you sign.
Demonstrated understanding of FCA financial promotions rules-confirm the agency knows that CTA copy on regulated pages must be signed off by an FCA-authorised person
Secure form handling for sensitive financial data: TLS 1.3, explicit no-storage policy for application data submitted via web forms
Calculator and comparison tool architecture: hardcoded rate sliders are not compliant; rates must pull from a backend with an audit log
FSCS protection wording display: this must appear in the correct format on the homepage and relevant product pages-agencies that don't know this will need post-launch legal correction
Load speed for product pages: Google strongly favours fast-loading financial pages because slow financial sites lose to comparison platforms in organic rankings
Platforms & Tech Stack
Next.js (custom)
The dominant choice for FCA-regulated web products in Johannesburg-gives full control over data handling, metadata, and component architecture without the compliance risks of page-builder CMS platforms.
React + Headless CMS (Contentful/Sanity)
Suitable for content-heavy financial services sites where legal and compliance teams need to update product information without developer involvement-with version control and approval workflows.
WordPress (custom theme-not page builders)
Acceptable for financial advisory firms and accountants with lower compliance complexity. Must be custom-themed-Elementor and Divi introduce security and accessibility vulnerabilities incompatible with FCA-regulated contexts.
Embedded compliance tools
Konsentus, Comply Advantage, and Onfido provide AML/KYC and PEP screening embeds. These are separate from website development but the agency should know how to integrate them without breaking page performance.

Questions & Answers
Pre-brief questions that fintech & finance businesses in Johannesburg ask before commissioning a web project.
Financial promotions communicated by FCA-regulated firms (or on their behalf) must be approved by the firm's compliance function or an FCA-authorised third party under Section 21 FSMA. This applies to product descriptions, rate claims, and CTAs on websites. Unauthorised financial promotions carry criminal liability. Any Johannesburg web agency working in financial services should flag this at the brief stage, not after launch.
WordPress is acceptable for lower-complexity financial advisory and accounting websites. It is not recommended for FCA-regulated product pages, client portals, or any site handling financial application data-the security attack surface of public plugins and the data handling of page builders like Elementor are incompatible with FCA-regulated environments. Next.js custom builds are the defensible choice for regulated products in Johannesburg.
An accountancy or financial advisory website costs £3,000–£9,000. An FCA-regulated product landing site with compliant copy and secure form handling costs £8,000–£25,000. A fintech startup marketing site with product integrations is £12,000–£40,000. These figures exclude legal review of financial promotions copy, which is a separate cost typically £1,000–£3,000 per compliance review.
