The verdict in three sentences
A premium B2B website redesign costs between 18,000 and 45,000 EUR (excl. VAT) in 2026, depending on the share of custom design, animations and technical SEO. The realistic timeline is 8 to 14 weeks, and the return shows on two axes: Core Web Vitals (LCP under 2.5 s) and form conversion (+30 to +60 %). Below 18,000 EUR you are buying a dressed-up theme; above 45,000 EUR you move into multilingual corporate territory.
What each price band covers
Price depends mostly on the degree of graphic customization and the volume of content to migrate. Here are the three levels we quote most often for a mid-market company.
| Level | 2026 price (excl. VAT) | Design | Pages | Timeline |
|---|---|---|---|---|
| Essential redesign | 18,000 - 24,000 EUR | Adapted premium template | 8 - 12 | 8 - 10 wks |
| Custom redesign | 25,000 - 34,000 EUR | 100 % custom design | 12 - 20 | 10 - 12 wks |
| Signature redesign | 35,000 - 45,000 EUR | Custom + advanced motion | 20 - 30 | 12 - 14 wks |
| Blog/news (option) | + 3,000 - 6,000 EUR | Editorial templates | - | + 1 - 2 wks |
| Annual maintenance | 150 - 400 EUR/mo | Security + updates | - | Ongoing |

Quote line items and deliverables by phase
A serious quote splits the engagement into billable lots, letting you trade off scope without breaking the project. Here is the typical structure and budget split on a 30,000 EUR redesign.
| Lot | Deliverable | Budget share | Timeline |
|---|---|---|---|
| Discovery & UX | Workshops, sitemap, wireframes | 12 % | 1 - 2 wks |
| UI design | Hi-fi mockups, design system | 22 % | 2 - 3 wks |
| Build & dev | Next.js, CMS, responsive | 34 % | 3 - 4 wks |
| Technical SEO | 301 redirects, schema, sitemap | 12 % | 1 wk |
| Content & migration | Reuse, editing, media | 10 % | 1 - 2 wks |
| QA & launch | Testing, Core Web Vitals, training | 10 % | 1 wk |
The technical SEO lot is non-negotiable in a redesign: without a 301 redirect map you lose acquired rankings and traffic drops 20 to 40 % the month after launch.
Mini case study
Mathieu, sales director of a mid-market wine company in Bordeaux, gets 60 quote requests a month through his old site (LCP at 4.1 s). He invests 30,000 EUR in a custom redesign. After launch, LCP drops to 2.2 s and the form conversion rate climbs +45 %, i.e. 27 extra requests a month. With an 8 % commercial close rate and a 12,000 EUR average deal, that is ~2.6 more contracts a month. The redesign pays for itself in under 2 months of added margin.

FAQ
Why does a premium redesign cost more than 18,000 EUR?
Because custom design, animations, Next.js build and technical SEO add up to 250-400 hours of work. A dressed-up WordPress theme costs 5,000-9,000 EUR but stays generic and caps out on performance.
How long does a redesign take?
Budget 8 to 14 weeks depending on scope. Discovery and design take the first third, build the second, QA and SEO migration the last. Late content delivery is the number one cause of slippage.
Will I lose my SEO when I switch sites?
No, provided the 301 redirect map is done properly, URL by URL. That is exactly the point of the technical SEO lot: we preserve the link structure and monitor indexing for 4 weeks after cutover.
What maintenance budget should I plan?
Between 150 and 400 EUR/month for security, backups, updates and small improvements. It is essential to keep Core Web Vitals healthy over time and avoid vulnerabilities.
Can I spread the cost?
Yes, billing by lots (30 % at discovery, 40 % at design/build, 30 % at QA) smooths cash flow over 3 months. Options like the blog can also be pushed to a phase 2.
