The verdict in three sentences
For a B2B SME in London, a solid brochure site costs between 5,000 and 10,000 EUR in 2026, a multilingual corporate site between 14,000 and 32,000 EUR, and a platform with a configurator or client portal starts at 40,000 EUR. What blows up a quote is almost never the design: it is the integrations (CRM, ERP, PIM), multilingual support and the volume of content to produce. A precise specification cuts the range by 20 to 30 % because it removes the uncertainty the agency otherwise prices in.
2026 price grid by tier
The ranges below reflect the London market, structured agencies (5 to 20 people), VAT excluded.
| Tier | Typical scope | Price EUR | Timeline |
|---|---|---|---|
| Essential brochure | 5-8 pages, 1 language, form | 5,000 - 7,500 | 4-6 wks |
| Advanced brochure | 10-15 pages, blog, on-page SEO | 7,500 - 10,000 | 6-8 wks |
| Bilingual corporate | 20-35 pages, EN/other, structured CMS | 14,000 - 22,000 | 8-12 wks |
| Premium corporate | multilingual, animation, press room | 22,000 - 32,000 | 12-16 wks |
| B2B platform | configurator, client portal, CRM sync | 40,000 - 80,000 | 16-24 wks |
The same site can vary twofold depending on whether the content (copy, photos, translations) is supplied or produced by the agency.
Budget line breakdown
On a corporate site at 20,000 EUR, the typical 2026 split looks like this.
| Line | Share | Amount EUR | What inflates it |
|---|---|---|---|
| Discovery & UX | 12 % | 2,400 | multiple workshops, personas |
| UI design | 18 % | 3,600 | bespoke mockups, motion |
| Development | 34 % | 6,800 | third-party integrations |
| Content & translation | 16 % | 3,200 | copywriting, extra language, photos |
| Technical SEO | 8 % | 1,600 | schema, perf, redirects |
| Integrations/API | 7 % | 1,400 | CRM, advanced forms |
| QA & launch | 5 % | 1,000 | cross-browser testing |
Annual maintenance adds on top: budget 15 to 20 % of the project cost per year (managed hosting, updates, fixes, small enhancements), i.e. 3,000 to 4,000 EUR/year in this example.
Mini case study
Thomas, marketing director of an industrial components manufacturer in Greater London, wants to replace a 2018 site generating 6 qualified leads a month. Target: 18 leads. He picks an advanced bilingual brochure at 16,000 EUR, plus 1,000 EUR of technical copywriting and 1,400 EUR of translation. Total first-year cost: 16,000 + 2,400 + 2,600 maintenance = 21,000 EUR. If each new lead is worth on average 3,500 EUR of margin and the site brings 12 more per month at an 8 % conversion rate, that is roughly 1 extra converted lead per month, i.e. 42,000 EUR of annual margin. The site pays for itself in under 7 months.

FAQ
Why do two agencies quote 6,500 and 18,000 EUR for "the same site"?
Because the scope is never identical: number of languages, content supplied or produced, level of animation, integrations. The 11,500 EUR gap sits 80 % in content and integrations, rarely in pure design.
Is a B2B site under 5,000 EUR possible?
Yes, on a semi-customised template and 4-5 pages, from around 3,000 EUR. But you lose technical SEO and integrations, which caps lead generation at 2-4 per month.
How much does multilingual cost?
Budget 15 to 25 % of the project per extra language: i18n structure (around 900-1,700 EUR) plus translation (14-20 EUR per 100 professional words). A 20,000-word site translated costs 2,800-4,000 EUR.
What is a realistic corporate timeline?
Between 8 and 16 weeks in London in 2026. The limiting factor is almost never the agency but the client's internal sign-off on content and visuals.
Is maintenance mandatory?
Not contractually, but a B2B site without security updates becomes vulnerable within 6-12 months. The 3,000-4,000 EUR/year package covers hosting, security and small enhancements.
