The verdict in three sentences
A premium B2B website in London costs between 15,000 and 28,000 EUR (excl. VAT) in 2026 for a fully bespoke build, versus 8,000 to 12,000 EUR for a well-executed WordPress template. The gap is justified by bespoke design, Next.js integration and strategic copywriting that turns the site into a sales tool. Expect 8 to 12 weeks, a 40% deposit and maintenance of 150 to 300 EUR/month.
The budget line by line
The price of a premium site is not a magic number: it is the sum of costable line items. Here is the breakdown of a typical fully bespoke 2026 project for a London industrial SME.
| Line item | 2026 range (EUR excl. VAT) | What moves the price |
|---|---|---|
| Bespoke UI/UX design | 6,000 - 9,000 | Number of mockups, animations |
| Next.js integration | 5,000 - 8,000 | Complexity, headless CMS |
| Copywriting & content | 2,500 - 4,000 | Number of pages, languages |
| Launch technical SEO | 1,000 - 2,500 | Audit, structure, schema |
| Project management | 1,500 - 3,000 | Duration, stakeholders |
| QA & go-live | 800 - 1,500 | Testing, admin training |
| Indicative total | 15,000 - 28,000 | 2026 order of magnitude |
The figures above assume a 6-to-10-page site, optionally bilingual, with a CMS for news and light CRM integration.
Template vs semi-bespoke vs fully bespoke
Three levels of ambition, three budgets. The right choice depends on the site's role in your B2B sales cycle.
| Criterion | WordPress template | Semi-bespoke | Fully bespoke Next.js |
|---|---|---|---|
| Budget (EUR excl. VAT) | 8,000 - 12,000 | 12,000 - 18,000 | 15,000 - 28,000 |
| Design | Adapted theme | Partial mockups | 100% dedicated |
| Performance (LCP) | 2.5 - 4 s | 1.8 - 2.5 s | 1.0 - 1.5 s |
| Timeline | 4 - 6 wks | 6 - 9 wks | 8 - 12 wks |
| Maintenance/month | 80 - 150 EUR | 120 - 220 EUR | 150 - 300 EUR |
| Scalability | Limited | Medium | High |
For an SME whose website is the first impression facing enterprise buyers, fully bespoke pays for itself on a single signed contract.
Mini case study
Thomas, CFO of a 45-employee industrial SME in London, budgets a premium site at 21,000 EUR (excl. VAT), amortised over 3 years, i.e. 583 EUR/month of smoothed cost including maintenance. His average sales cycle involves contracts of 40,000 EUR. If the new site converts even 2 extra qualified quote requests per year, the return on investment is reached on the first signature. The decision math becomes trivial.

FAQ
Why an 8,000-to-28,000 EUR gap for a "simple" showcase site?
Because a template reuses an existing design whereas bespoke designs every screen. In B2B, the difference in perceived credibility can mean several percentage points of conversion on five-figure deals.
What deposit does an agency require in 2026?
The norm is a 40% deposit at signature, 30% at mockup approval and 30% on delivery. Some premium projects move to 50/50.
How much is post-delivery maintenance?
Between 150 and 300 EUR/month for a premium site: security updates, backups, small enhancements and managed hosting included.
Does a bilingual EN/FR site change the price much?
Yes, expect +15 to 18% on the overall budget for technical structuring, professional translation and SEO dedicated to each language.
Can you deliver in under 8 weeks?
It is possible with semi-bespoke or a reduced scope, but a true fully bespoke premium build needs 8 to 12 weeks for the expected finishing quality.
