The verdict in three sentences
For a regional mutual health insurer with 40,000 members and a 120-page site that no longer works on mobile, a serious redesign in the Netherlands costs between 60,000 and 110,000 EUR and takes 4 to 6 months. The two items that move the bill are WCAG 2.2 AA compliance and a 3-level editorial approval workflow in a headless CMS. The maintenance budget, around 1,500 EUR a month, must be approved together with the redesign, otherwise the site degrades within 18 months.
Redesign budget breakdown
A mutual insurer's institutional site mixes regulated content (cover, policy terms, premiums), a member portal and news. The redesign splits into work packages, each with its own weight.
| Work package | 2026 range | Share of budget |
|---|---|---|
| Audit, inventory of 120 pages and information architecture | 5,500 to 10,000 EUR | 9 % |
| UX and accessible design system | 10,500 to 19,000 EUR | 17 % |
| Front-end and headless CMS development | 24,000 to 44,000 EUR | 40 % |
| 3-level approval workflow (editor, legal, management) | 5,500 to 10,000 EUR | 9 % |
| WCAG 2.2 AA audit and fixes | 7,000 to 12,500 EUR | 11 % |
| Content migration and rewriting | 5,500 to 10,000 EUR | 9 % |
| Testing, training and go-live | 2,000 to 4,500 EUR | 4 % |
The upper end, around 110,000 EUR, covers insurers that add a premium calculator, a connector to the member administration system or advanced search across policy documents.
WCAG 2.2 AA: a requirement, not an option
The European Accessibility Act, applicable since June 2025, brings consumer banking and insurance services into scope, and Dutch insurers are expected to meet WCAG 2.2 AA through EN 301 549. A mutual insurer should target AA with a published accessibility statement.
| Criterion | Current site (typical finding) | Target after redesign |
|---|---|---|
| WCAG conformance rate | 35 to 50 % | 90 % and above |
| Compliant colour contrast | 60 % | 100 % |
| Accessible PDF documents | Under 10 % | Key policy terms in HTML or tagged PDF |
| Full keyboard navigation | Partial | Complete, including menus and forms |
| Mobile load time (LCP) | 5 to 7 s | Under 2.5 s |
| Pages to convert to HTML | 30 to 40 PDF documents | Main cover pages in HTML |
Accessibility must start at wireframe stage. Fixing it afterwards usually costs 1.5 to 2 times more than building it in.
Why a headless CMS with 3-level approval
At a mutual insurer, a cover page never goes live without legal review. A headless CMS such as Sanity or Strapi lets you define roles (editor, legal counsel, communications director), block publication until all three approvals are given and log every change. The Next.js front end stays fast and accessible regardless of editorial choices. Budget 5,500 to 10,000 EUR to configure the workflow, plus half a day of training per role.
Maintenance at around 1,500 EUR a month covers security updates, monitoring, roughly 6 hours of monthly improvements and tracking of the WCAG conformance rate.

Sanne, communications director of a mutual insurer in Amsterdam with 40,000 members, sees her member service centre handle 1,800 calls a month on questions already answered on the site. After an 85,000 EUR redesign, with cover pages in HTML and effective search, 20% of those calls move to self-service, or 360 calls avoided. At 7 EUR average cost per handled call, savings reach 2,520 EUR a month, about 30,000 EUR a year. With maintenance at 18,000 EUR a year, payback on this item alone is around seven years, before counting brand gains and online sign-ups.
FAQ
What budget should a mutual health insurer plan for a website redesign in 2026?
Expect 60,000 to 110,000 EUR for a 120-page site with a headless CMS and AA accessibility. A premium calculator or system connectors push towards the upper end.
How long does the redesign take?
Between 4 and 6 months, including 4 to 6 weeks of audit and information architecture. Legal approval of content is often the critical path.
Is WCAG 2.2 AA mandatory for a Dutch insurer?
Insurance services fall within the European Accessibility Act since June 2025. Targeting 90% AA conformance and publishing an accessibility statement protects the organisation.
Why a headless CMS rather than classic WordPress?
Headless separates editing from the front end, which secures load times under 2.5 s and a traceable 3-level approval workflow. The upfront premium is around 10 to 15%.
What does 1,500 EUR a month of maintenance cover?
Security updates, monitoring, backups and about 6 hours of monthly improvements. It also includes tracking the WCAG conformance rate.
