Real pricing based on 50+ B2B projects: from brochure sites to enterprise platforms. No fluff — just the numbers, hidden costs, and what you actually need to grow.
Most B2B founders searching “how much does a B2B website cost” get two answers: a vague range with no explanation, or an agency blog dressed up as advice. This is neither. We’ve built websites for manufacturers, SaaS firms, ERP buyers, and professional services. Here’s what it actually costs and why — all real UK numbers for 2026.
£3k–£8k | 5–8 pages, basic contact form, template design
£8k–£25k | custom design, SEO architecture, case studies, CMS
£60k–£150k+ | portals, CRM sync, headless, full integration
B2B website cost by type — UK 2026 (real ranges)
| Type | Price range | What’s included | Timeline |
|---|---|---|---|
| Brochure site | £3,000 – £8,000 | 5–10 pages, template / light custom, basic on‑page SEO, contact form | 4–8 weeks |
| Mid-range lead gen site | £8,000 – £25,000 | 12–25 pages, custom design, CMS (Webflow/WordPress), proper SEO structure, industry landing pages, blog | 8–16 weeks |
| Custom with integrations | £25,000 – £60,000 | CRM integration, gated content, ABM pages, advanced performance tracking, ongoing SEO foundation | 16–28 weeks |
| Enterprise / platform | £60,000 – £150,000+ | Bespoke front‑end, portals, headless CMS, WCAG 2.2 AA, high‑load architecture | 28+ weeks |
What actually drives the cost up
Number of unique page designs
20 pages with 4 repeating templates costs far less than 20 bespoke layouts. Most efficient B2B sites use 5–6 templates that adapt to content.
Custom functionality
Quote calculators, multi‑step conditional forms, CRM sync, product configurators — each adds days or weeks of dev. Be specific about must‑haves vs nice‑to‑haves.
Content production
Copywriting for a 25‑page B2B site done properly (keyword research, positioning, conversion flow) costs £3k–£8k. Internal content saves money but often delays launches by months.
SEO technical setup
Schema markup, clean URL structure, Core Web Vitals, sitemap, robots.txt – budget £1,500–£3,500 during build. Retrofitting SEO costs 3x more.
Hidden costs most agencies don’t mention
- Hosting: Webflow (£20–£50/mo), managed WordPress (£30–£150/mo).
- Post‑launch support: Expect £200–£600/mo for responsive maintenance.
- CRM integrations: Basic webhooks are free; two‑way sync with lead scoring starts at £1,500–£5,000.
- Analytics & tracking: GA4 is free, but proper conversion tracking, heatmaps, call tracking adds £800–£2,500 setup.
- Ongoing SEO: £800–£3,000/month for a consistent programme – cheaper than an in‑house hire for most sub‑£5m businesses.
B2B website cost vs ROI – how to frame your budget
Stop asking “how much?” and start asking: what’s one extra qualified B2B lead worth? If your average client contract is £18,000 and you close 1 in 4 leads, a single extra lead per month = £54,000/year in new revenue. Suddenly a £20k website is a no‑brainer.
Budget summary: what to allocate in 2026
Platform comparison: Webflow vs WordPress vs custom (React/Next.js)
| Platform | Build cost | Maintenance (year) | Best for |
|---|---|---|---|
| Webflow | £5k – £18k | Low (£500–£1.5k) | B2B companies wanting quality without dev dependency |
| WordPress | £7k – £25k | Medium (£1.2k–£3k) | Large content ops, specific plugin ecosystems |
| React / Next.js | £25k – £80k+ | Higher | B2B SaaS, portals, performance‑critical applications |
We build across all three — the recommendation depends on your internal team and long‑term goals, not on what’s easiest to sell.
What to ask any web agency before signing
- Can you show me three B2B websites you’ve built in the last 18 months? (Live URLs, not just logos.)
- What’s included in your SEO setup? (title tags, schema, redirects – be specific.)
- Who writes the copy? Agency, freelancer, or us? If us, what briefing do you provide?
- What happens at handover? Do we own the CMS and hosting? Training session included?
- How do you handle scope changes? Hourly rate or change‑request process?
Frequently asked questions (B2B website cost UK)
How much does a B2B website cost in the UK in 2026?
Between £3,000 for a simple brochure site and £150,000+ for enterprise platforms. Most growth‑focused B2B companies should budget £8,000–£25,000 for a proper lead generation site that actually ranks and converts.
How long does a B2B website take to build?
For a typical lead gen site with client content ready, 10–16 weeks. Add 4–6 weeks if content is being produced during the project.
Should I use a B2B-specific agency or a general web agency?
A B2B-focused agency understands longer sales cycles, multi‑stakeholder decisions, and what convinces a procurement manager. That context shapes every decision – from page structure to CTAs.
What is included in B2B SEO alongside website development?
On‑page SEO at build stage: keyword research, optimised title tags & meta descriptions, schema markup (Organization, BreadcrumbList, Service), clean URLs, internal linking, sitemap and robots.txt. Budget £1,500–£3,500 as part of the build.
What are the hidden costs of a B2B website?
Hosting, support retainers, CRM integrations, analytics setup, and ongoing SEO content. Expect £2,000–£8,000 per year in operational costs on top of the build budget.
Is Webflow or WordPress better for B2B?
Webflow is faster to build and easier for marketing teams. WordPress suits large content operations with specific plugin needs. React/Next.js is best for portals or performance-critical applications. We advise based on your internal resources, not preference.
