The verdict in three sentences
A premium B2B website in London costs between GBP 4,000 and GBP 28,000 in 2026 depending on design depth, content and integrations. The real price gap comes not from page count but from bespoke UX, performance and search optimisation. A 29-per-month SaaS template looks ten times cheaper, but it replaces neither a credible brand image nor a conversion funnel built to sell B2B.
The 2026 price grid by tier
Here are the ranges seen at serious London agencies in 2026 (order of magnitude, excluding VAT at 20 %).
| Tier | Price ex-VAT | Pages | Timeline | Included |
|---|---|---|---|---|
| Starter | GBP 4,000 - 6,500 | 5 to 8 | 4-5 wks | Theme-based design, responsive, form, basic SEO |
| Growth | GBP 6,500 - 13,000 | 8 to 15 | 5-7 wks | Bespoke design, blog, analytics, advanced SEO |
| Premium | GBP 13,000 - 28,000 | 15 to 30 | 7-10 wks | Animations, motion design, multilingual, optimised CWV |
| Custom | GBP 28,000 + | 30 + | 10-16 wks | Design system, CRM/ERP integrations, A/B testing |
On top of these come the recurring costs, often underestimated in first quotes.
| Recurring item | 2026 range | Frequency |
|---|---|---|
| Managed hosting | GBP 20 - 80/mo | Monthly |
| Maintenance & security | GBP 80 - 250/mo | Monthly |
| Domain name | GBP 12 - 40/yr | Annual |
| SEO retainer | GBP 400 - 1,500/mo | Optional |
| Partial redesign | GBP 1,500 - 4,000 | Every 2-3 yrs |
Bespoke agency or a 29-per-month SaaS template?
The busy director's reflex is to compare an 8,000 quote with a Webflow or Wix subscription at 29/month. Over three years the template comes to about GBP 1,044, versus GBP 8,000 + 150/month maintenance = GBP 13,400 for bespoke. The gap is real, but the template delivers no strategic positioning, no copy written to convert, and no fine technical optimisation. For an SME signing contracts worth 20,000 - 200,000, a single client won thanks to the site repays the whole premium budget.
Note: in the UK, some digital adoption grants and R&D reliefs may cover part of a digitalisation spend in 2026 depending on eligibility, worth checking before signing.
Mini case study
Thomas, director of a 24-person engineering SME in central London, hesitates between a Growth build at 9,000 and a template at 29/month. His average B2B deal is 50,000. The Growth site brings 6 extra qualified enquiries a year; he closes 2, worth GBP 100,000 in revenue. Total first-year cost: 9,000 + 1,800 maintenance = GBP 10,800. First-year ROI: over 825 %. The template would have generated neither the credibility nor the SEO for those enquiries.

FAQ
Why a 1-to-7 gap between quotes?
Bespoke design, copywriting, multilingual scope and Core Web Vitals optimisation explain most of it. A 4,000 quote relies on an adapted theme; a 28,000 quote delivers a unique design and integrations.
Is VAT always added?
Yes, UK agency prices are ex-VAT and 20 % is added for a business client. A 10,000 quote therefore costs 12,000 including VAT, recoverable if you are VAT-registered.
How long to deliver a premium site?
Allow 7 to 10 weeks for Premium, longer if content is not ready. The number-one delay factor remains internal sign-off on copy and visuals.
Can a 4,000 site be enough?
Yes for a simple, credible presence. But if your London market is competitive, the SEO and design of the Growth tier often make the difference on contact rate.
Are digital grants worth checking?
Depending on the scheme and year, some support may apply to a digitalisation spend. Verify eligibility case by case before committing.
