The verdict in three sentences
For a 120,000-member insurer, a website redesign is a EUR 40,000 to 110,000 project, and the spread depends mostly on the premium calculator and the member portal. A vague spec makes the budget drift by 20 to 40 %; a precise spec in 12 sections lets you compare three bids line by line. Allow 60 to 90 days to produce it with business teams, legal and compliance.
The 12-section requirements spec outline
| No. | Section | Expected content | Internal owner |
|---|---|---|---|
| 1 | Context and goals | Key figures, target KPIs (quotes, online sign-ups) | Digital lead |
| 2 | Functional scope | Sitemap, 60 to 120 page templates | Marketing |
| 3 | Personas and journeys | Individuals, self-employed, employers, brokers | Marketing |
| 4 | Premium calculator | Pricing rules, cover levels, ages, deductible | Actuarial |
| 5 | Member portal | Claims, policy documents, insurance card | Operations |
| 6 | Online sign-up | Steps, e-signature, IBAN mandate | Sales |
| 7 | CMS and governance | Roles, 2 or 3 level approval workflow | Communications |
| 8 | Compliance | AFM duty of care, IPID, GDPR, cookies | Compliance and DPO |
| 9 | Accessibility | WCAG 2.1 AA, European Accessibility Act | Digital |
| 10 | Integrations | Policy admin system, CRM, DMS, SSO | IT |
| 11 | Technical requirements | Hosting, security, performance, exit plan | IT and CISO |
| 12 | Tender process | Timeline, scoring grid, response format | Procurement |
Section 4 is the most underestimated. Without a rules table approved by actuarial (age bands, cover levels, voluntary deductible, supplementary packages), an agency can only price assumptions. Provide a rules file with 50 to 200 expected test cases.
Budget by functional block
| Block | 2026 range | Driver |
|---|---|---|
| Design and UX (workshops, mockups, design system) | EUR 8,000 to 18,000 | Number of journeys |
| Public site and headless CMS | EUR 12,000 to 28,000 | Templates and editorial workflow |
| Premium calculator | EUR 6,000 to 22,000 | Number of products and rules |
| Member portal (front end on APIs) | EUR 8,000 to 25,000 | Existing back-end APIs |
| Online sign-up with e-signature | EUR 4,000 to 12,000 | KYC and DMS integration |
| Accessibility audit | EUR 2,000 to 5,000 | Page volume |
| Total redesign | EUR 40,000 to 110,000 | Excluding maintenance |
| Maintenance and enhancements | EUR 1,200 to 3,500/month | SLA and volume |
The specification itself has a cost: an external business analyst bills 15 to 25 days at EUR 700 to 1,000, i.e. EUR 10,500 to 25,000. Many insurers do it in-house, but the 60 to 90 day timeline then depends on business team availability.
Compliance: what the AFM and the Dutch DPA look at
An insurer's website is a distribution channel. It must deliver the standardised product information document (IPID) before sign-up, record the duty of care (timestamped and archived needs questionnaire) and make switching rules clear, which matters in the Netherlands where members can switch basic health cover every year before 1 January. On GDPR, any health data collected during sign-up requires strict access controls and a DPIA. Write these requirements into sections 8 and 11, with the evidence expected at acceptance.
Mini case study
Sanne, digital lead at a 120,000-member insurer in Amsterdam, receives 9,000 quote requests a year, 30 % of them through the website. She budgets EUR 78,000 for the redesign, with a EUR 14,000 calculator and a member portal plugged into existing APIs. Goal: go from 2,700 to 4,500 online quotes a year and from an 8 % to a 10 % sign-up rate. Expected result: 450 sign-ups instead of 216, i.e. 234 additional members. With an average supplementary premium of EUR 1,100 a year, that is EUR 257,400 of new annual premiums. The redesign pays back in under a year, even with EUR 2,500 a month of maintenance.
