Best CMS for a B2B website in London in 2026

Websites

The verdict in three sentences

For a London B2B services firm that needs a 10 to 60 page site its marketing team can edit, WordPress with a lean block theme is still the best balance of cost, autonomy and portability in 2026. Webflow pulls ahead for design-led teams that change layouts often and accept a monthly plan with weaker portability, while Wix suits sites under 15 pages with modest search ambitions. Headless, from around 15,000 GBP, only pays off with several sites, several languages or heavy integrations.

Ranking CMS options for a B2B firm

This ranking compares well-known public software on stable criteria. Budgets are 2026 estimates for a B2B site delivered by an agency or studio, excluding 20 % VAT.

Kolonell is one of the possible providers for a fast custom site: Starter from 610 to 1,145 EUR (5 pages, 7 to 10 working days) or Premium from 1,200 to 2,300 EUR (21 to 30 days), with maintenance from 38 EUR a month. Weigh these against the ranges above for your page count and integrations.

WordPress is free only on paper: plugins and core need monthly updates, so maintenance is heavier. Webflow and Wix bundle hosting and security, but you depend on their pricing changes.

Performance and compliance thresholds to require

RequirementTargetWhat usually breaks it
LCP (main content load)Under 2.5 secondsUnoptimised images, heavy themes
INP (responsiveness)Under 200 millisecondsThird-party scripts, chat widgets, pixels
CLS (visual stability)Under 0.1Cookie banners, late-loading fonts
Cookie consentUK GDPR and PECR compliant, no tracking before consentAnalytics tags firing on page load
AccessibilityWCAG 2.2 AA on key pagesLow contrast, missing labels on forms

All four options can hit these targets, with very different effort. Write them into the contract, measured on your 5 most visited pages, and make sure copy uses British spelling and UK-specific proof points such as accreditations and case studies from UK clients.

Mini case study

Illustrative example: Oliver, managing partner of a 15 person IT consultancy in London, wants his team to publish case studies and 2 articles a month on a 35 page site. He compares WordPress at 10,000 GBP and headless at 22,000 GBP.

Over three years WordPress comes to about 15,000 GBP and headless to about 32,000 GBP. The 17,000 GBP gap would fund three years of content production. With one site, one language and only a CRM form integration, Oliver picks WordPress, writes an LCP under 2.5 seconds into the contract and books a 3 hour training session for his team.

FAQ

Is WordPress still a good choice for a B2B website in 2026?

Yes for most firms with 10 to 60 pages, provided you keep plugins to around 15 and pay for maintenance. Hosting costs 100 to 500 GBP a year.

Webflow or WordPress for a London services firm?

Webflow if marketing changes layouts often and accepts a monthly plan. WordPress if you want full ownership and a build budget of 4,000 to 18,000 GBP.

When should we go headless?

With two or more sites, three languages or deep CRM or ERP integrations. Budgets start around 15,000 GBP, and layout changes usually need a developer.

Is Wix credible for B2B?

For a site under 15 pages without ambitious SEO goals, yes. Beyond that, limited portability and technical control start to cost you.

How long does a 30 page B2B site take?

Four to 10 weeks depending on the CMS and content readiness. Late copy and images cause over half of timeline overruns.
