The verdict in three sentences
A credible B2B brochure site in London starts around EUR 6,000, a structured multi-page corporate site with SEO sits between EUR 14,000 and EUR 25,000, and a platform with a configurator or client area exceeds EUR 35,000. Price is not driven by page count but by functional depth, the volume of content to produce, and the level of integration with your systems. An honest quote itemises each line: underestimating content and integrations is the number-one cause of overrun.
2026 price grid by tier
The ranges below reflect the London market for a B2B SME (10 to 250 staff), a quality agency or studio, excluding low-cost providers and large networks.
| Tier | Typical scope | Price EUR | Timeline |
|---|---|---|---|
| Essential brochure | 5-8 pages, 1 language, form | 6,000 - 10,000 | 4-6 weeks |
| Structured corporate | 12-20 pages, blog, SEO, bilingual | 14,000 - 25,000 | 8-12 weeks |
| Corporate + configurator | Simulator, client area, CRM | 30,000 - 45,000 | 12-18 weeks |
| Bespoke platform | Portal, API, multi-site | 45,000 - 90,000+ | 4-8 months |
Key point: the gap between the brochure and corporate tiers is not four extra pages, it is an editorial strategy, SEO internal linking, and content governance that change the very nature of the project.
Line-by-line breakdown
A serious quote shows these lines. Here are 2026 orders of magnitude for a corporate site at EUR 18,000.
| Line item | Share of budget | Amount EUR |
|---|---|---|
| Discovery & UX (sitemap, wireframes) | 15 % | 2,700 |
| UI design (mockups, design system) | 20 % | 3,600 |
| Front-end development (Next.js) | 30 % | 5,400 |
| CMS integration & content | 15 % | 2,700 |
| Technical SEO & copywriting | 12 % | 2,160 |
| QA, performance, go-live | 8 % | 1,440 |
The two most frequently underestimated lines are copywriting (a credible B2B site needs 15 to 30 pages of expert content) and QA (cross-browser testing, accessibility, Core Web Vitals). Also budget for recurring costs: managed hosting and maintenance run EUR 150 to 600/month depending on traffic.
The 6 variables that move the quote
| Variable | Impact on price |
|---|---|
| Multilingual (EN/FR/DE) | +25 to +40 % |
| Configurator or simulator | +EUR 8,000 to 20,000 |
| Client area / extranet | +EUR 12,000 to 30,000 |
| CRM integration (HubSpot, Salesforce) | +EUR 3,000 to 9,000 |
| Content volume (>25 pages) | +EUR 2,000 to 6,000 |
| Advanced animation & motion design | +15 to 25 % |
A quote that fails to isolate these variables is a risky quote: you will discover the extra costs mid-project.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Sophie, marketing director of an industrial mid-cap in London (140 staff), wants to replace a dated site generating 12 leads/month. Target: 40 qualified leads/month. She chooses the corporate tier at EUR 19,000, plus EUR 4,000 for a product configurator, totalling EUR 23,000, and EUR 350/month for maintenance and SEO.
With an average B2B deal size of EUR 8,000 and a 12 % lead-to-customer rate, going from 12 to 40 leads/month adds 28 leads, i.e. ~3.4 extra customers/month = EUR 27,000 of additional monthly revenue. The EUR 23,000 investment is recovered in under two months of marginal revenue. The real question is therefore not the price of the site, but how fast it starts converting.
FAQ
What is the cheapest B2B site that still looks credible in 2026?
Expect a minimum of EUR 6,000 for a professional Next.js brochure site with a CMS, basic SEO, and a form. Below that, you get a generic template that damages your image with B2B buyers.
Why does a corporate site cost three times more than a brochure site?
Because you are paying for an editorial strategy, 15 to 30 pages of expert content, SEO internal linking, and content governance. The price gap (EUR 6,000 vs 18,000) reflects a change of nature, not just size.
What recurring budget should I plan after launch?
Between EUR 150 and 600/month for managed hosting, security maintenance, and minor updates. Add EUR 800 to 2,500/month if you outsource SEO and content to an agency.
How long does a B2B site take to deliver?
From 4-6 weeks for a brochure site to 12-18 weeks for a corporate site with a configurator. Content, not development, is the factor that stretches timelines the most.
Is a configurator or simulator worth the extra cost?
Yes for most B2B SMEs: a quote or ROI simulator lifts conversion by 20 to 45 % and qualifies leads before the first sales contact, quickly paying back the EUR 8,000 to 20,000 invested.
