The verdict in three sentences
A professional B2B brochure website in London costs between 4,500 and 9,000 EUR in 2026, a structured corporate site between 12,000 and 30,000 EUR, and a site with a configurator or client portal exceeds 45,000 EUR. What blows up a quote is almost never the design: it is the integrations (CRM, ERP, PIM), the content production and the number of bespoke templates. A clear specification halves the price gap between vendors.
2026 pricing grid by tier
The ranges below apply to a London B2B SME working with an established agency or studio (not a junior freelancer, nor a large advertising agency).
| Tier | Scope | Price EUR | Timeline |
|---|---|---|---|
| Essential brochure | 5-8 pages, 1 form, simple blog | 4,500 - 9,000 | 4-6 weeks |
| Corporate | 15-25 pages, multilingual, blog, case studies | 12,000 - 30,000 | 8-12 weeks |
| Corporate + configurator | Client area, configurator, CRM connector | 45,000 - 80,000 | 14-20 weeks |
| Portal / platform | Auth, catalogue, online quoting, ERP | 80,000 - 150,000+ | 5-8 months |
On top of these come recurring costs that are often underestimated: managed hosting (80 to 300 EUR/month), corrective and evolutive maintenance (300 to 900 EUR/month), and SEO (900 to 2,500 EUR/month depending on ambition).
Quote breakdown, line by line
For a corporate site at 20,000 EUR, here is how the budget typically splits. Understanding this breakdown lets you negotiate intelligently.
| Line item | Share of budget | Indicative amount EUR |
|---|---|---|
| Discovery & UX (structure, wireframes) | 15 % | 3,000 |
| UI design (mockups, design system) | 20 % | 4,000 |
| Build & development | 35 % | 7,000 |
| Content & copywriting | 12 % | 2,400 |
| Third-party integrations (CRM, analytics) | 10 % | 2,000 |
| QA, technical SEO, go-live | 8 % | 1,600 |
Two levers dominate the variability. First, the number of unique templates: each bespoke page type (product page, sector page, dedicated landing) adds 800 to 2,000 EUR. Second, the content production: if your copy, photography and case studies are not ready, budget an extra 2,000 to 6,000 EUR for writing and art direction.
Mini case study
Thomas, marketing director of a 45-person industrial SME in Croydon, wants to replace an ageing brochure site that generates 3 qualified leads per month. He targets a corporate site at 22,000 EUR with 18 pages, a blog, 6 case studies and a HubSpot connector. Adding copywriting (technical sheets exist but not web copy: +4,000 EUR), the total budget reaches 26,000 EUR.
His goal: go from 3 to 9 qualified leads per month. With an average deal of 18,000 EUR and a 20 % sales conversion rate, 6 extra leads per month represent 1.2 won deals monthly, roughly 259,000 EUR in additional annual revenue. The 26,000 EUR investment is recouped in under two months of sales outperformance — provided SEO and content keep pace.

FAQ
What is the minimum price for a credible B2B site in 2026?
Below 4,500 EUR, you get an adapted theme, not a bespoke site. For an SME that wants to inspire trust in professional buyers, that is the realistic floor with a serious studio.
Why can two quotes vary threefold?
The gaps come from the level of customisation, the number of templates, CRM/ERP integrations and the share of content included. A precise specification narrows quotes to plus or minus 15 %.
Do I have to pay for monthly maintenance?
Yes: an unmaintained B2B site accumulates security flaws and technical debt. Budget 300 to 900 EUR/month for updates, backups, fixes and small improvements.
How long until delivery?
A brochure site ships in 4 to 6 weeks, a corporate site in 8 to 12 weeks. The main delay factor is client-side content approval, not development.
Is SEO included in the site price?
Technical SEO (structure, speed, tags) is usually included. Editorial SEO and link-building are separate recurring services, starting at 900 EUR/month.
