The verdict in three sentences
An institutional website redesign in Berlin for a 30-to-80-page group costs between 30,000 and 55,000 EUR (excl. VAT) in 2026. The budget is structured around four heavy line items: UX audit, design system, headless CMS development and content migration. The BITV/WCAG 2.1 AA accessibility requirement adds 15 to 20% to the budget, for a realistic timeline of 14 to 20 weeks.
The budget line by line
An institutional redesign is not a simple facelift: it is a content governance project. Here is the 2026 breakdown for a multilingual Berlin group.
| Line item | 2026 range (EUR excl. VAT) | Scope |
|---|---|---|
| UX audit + information architecture | 3,500 - 6,000 | Analysis, card sorting, sitemap |
| Design system | 8,000 - 14,000 | Components, tokens, variants |
| Headless CMS development | 12,000 - 22,000 | Integration, editorial workflow |
| Content migration | 4,000 - 7,000 | Reuse, rewrite, redirects |
| BITV/WCAG AA accessibility | +15 to 20% | Audit + fixes |
| Indicative total | 30,000 - 55,000 | 2026 order of magnitude |
These figures include bilingual EN/DE, a multi-level editorial approval workflow and a formal accessibility QA.
Standard vs Premium: two redesign tiers
The functional scope shifts the budget from one tier to the other. Here are the two most requested levels in 2026.
| Criterion | Corporate Standard | Corporate Premium |
|---|---|---|
| Budget (EUR excl. VAT) | 30,000 - 40,000 | 42,000 - 55,000 |
| Number of pages | 30 - 50 | 50 - 80 |
| Languages | EN/DE | EN/DE + 1 |
| Editorial workflow | 2 levels | 3+ levels |
| Integrations | Newsletter, analytics | ERP/CRM, portal |
| Accessibility | WCAG AA | WCAG AA + external audit |
| Support | 6 months | 12 months + SLA |
Moving to Premium is justified as soon as you need to connect the site to an intranet, an ERP or a secure partner portal.
Mini case study
Céline, communications director of a 600-person industrial group in Berlin, budgets a redesign at 46,000 EUR (excl. VAT), amortised over 4 years, i.e. 958 EUR/month. The old site generated 35 spontaneous applications/month and a 68% bounce rate. After redesign, the goal is +40% HR and sales leads thanks to a clarified journey and load time cut by three. On a single executive hire avoided via a headhunter (average cost 18,000 EUR), the redesign is partly amortised in the first year.

FAQ
Why does an institutional redesign cost more than a showcase site?
Because it combines content governance, multi-level approval workflow, multilingual delivery and regulatory accessibility. The headless CMS and migration of dozens of pages weigh heavily on the budget.
Is BITV/WCAG accessibility mandatory?
For public bodies and many large groups, yes. It adds 15 to 20% to the budget but reduces legal risk and widens the audience. It is an investment, not a constraint.
How long does a redesign of this scale take?
Expect 14 to 20 weeks between kick-off and go-live, migration and accessibility QA included. A multilingual premium scope can approach 24 weeks.
Can we keep our current CMS?
Sometimes, but a modern headless CMS (like Sanity or Strapi) brings a real workflow and performance gain. The migration costs between 4,000 and 7,000 EUR.
How do we protect the budget against overruns?
By precisely scoping the information architecture and number of templates from the UX audit. It is this initial 3,500-to-6,000 EUR line item that locks in the rest of the estimate.
