The verdict in three sentences
A B2B website redesign budgets between 3,000 and 30,000 EUR in 2026 depending on whether you start from a template, semi-custom or full custom build. The price is not arbitrary: development (40%) and UX/UI (25%) make up two thirds of the quote, the rest splits across content, SEO and project management. Add 10 to 20% of the build cost per year for maintenance and you have the true cost of ownership.
The three options and their 2026 ranges
The first price lever is the degree of customisation. An adapted template is cheap but you will resemble others; full custom aligns design and conversion perfectly but burns more man-days.
| Option | 2026 price (EUR) | Timeline | Pages | Design |
|---|---|---|---|---|
| Adapted template | 3,000 - 6,000 | 4 weeks | 5-8 | Themed |
| Semi-custom | 8,000 - 15,000 | 8 weeks | 10-20 | Dedicated mockups |
| Full custom | 15,000 - 30,000 | 12 weeks | 20+ | Own design system |
| Full custom + | 30,000+ | 14-16 weeks | 30+ | Art direction |
At equal scope, a 4,000 EUR quote and a 12,000 EUR quote do not sell the same thing: the second includes unique mockups, professional copywriting and real SEO work, not just theme installation.
Where the money goes: the five cost items
Understanding the split lets you make trade-offs. If your content is ready and photos exist, you save the copywriting item. If you want page one on Google, do not cut SEO.
| Item | Share of quote | On a 12,000 EUR project | Reducible? |
|---|---|---|---|
| Development | 40% | 4,800 EUR | Little |
| UX / UI | 25% | 3,000 EUR | Partly |
| Content / copy | 15% | 1,800 EUR | Yes if supplied |
| Technical SEO | 10% | 1,200 EUR | Not advised |
| Project management | 10% | 1,200 EUR | No |
Annual maintenance is the forgotten budget line. Count 10 to 20% of build cost per year: on a 12,000 EUR site that is 1,200 to 2,400 EUR/year for updates, security and small evolutions.
Mini case study
Claire, CFO of a 40-person industrial SME in London, must sign off a redesign budget. Her site dates from 2019, no longer converts and is not responsive. She hesitates between a 5,000 EUR template and a 13,000 EUR semi-custom. Her sales lead estimates a credible site brings 3 more qualified enquiries per month, i.e. 36 leads/year; at a 20% close rate and an 8,000 EUR average deal, that is 57,600 EUR of additional annual revenue. The 8,000 EUR gap between the two options is recouped in under two months of extra sales. Claire picks semi-custom and budgets 2,000 EUR/year of maintenance, a first-year total cost of ownership of 15,000 EUR.

FAQ
Why does a quote swing threefold for the same need?
Because "brochure website" covers both a theme installed in 3 days and a custom design of 30 man-days. With unscoped requirements, the quote spread routinely hits 60%. A precise specification cuts it to 15%.
Is full custom always worth the premium?
No. For an SME under 15 pages with no strong differentiation need, a semi-custom at 8,000-15,000 EUR delivers 90% of the result for half the price. Full custom is justified beyond 20 pages or when brand image is a commercial asset.
How much is annual maintenance?
Count 10 to 20% of build cost per year. On a 12,000 EUR site that is 1,200 to 2,400 EUR/year covering security, backups, updates and 2 to 5 hours of monthly evolutions.
Can I lower the bill without sacrificing quality?
Yes: supplying written content and photos saves the copywriting item (15%), and delivering a validated sitemap reduces UX back-and-forth. Never cut technical SEO or project management.
Should I pay a deposit?
Yes, a 30 to 40% deposit at kickoff is standard in 2026, with the balance staged across acceptance milestones. Beware any provider demanding 100% upfront.
