B2B Using Contentful in the UK: 198 Active Firms (2026)
B2B firms running headless content management systems sell products or services to other organisations, with UK websites built for structured digital content.
For B2B suppliers, a headless content platform usually sits between product marketing, demand generation and web engineering rather than inside a purely editorial team. It lets content teams maintain structured product pages, resource libraries, partner pages and localisation workflows while developers control the front end. Adoption tends to signal a direct-channel posture: the company expects its website to support education, qualification and sales hand-off, not just corporate credibility. It also implies some internal capacity for marketing operations, analytics tagging and release governance, because the system has to connect with forms, CRM processes and campaign measurement.

The UK adoption footprint is narrow: 198 actively trading B2B firms run this headless CMS on public websites. Within detected CMS usage for the B2B sector, it sits ninth in the category-share ranking at 0.2%, behind lower-friction site builders and more familiar open-source publishing systems. London accounts for 43.4% of the cohort, followed by the South East at 14.6%, the North West at 10.6%, the East of England at 6.6% and the South West at 6.1%. Reported employment across the cohort totals 3,600 people, pointing to use by specialist teams as well as larger commercial organisations.
Adoption sits inside ordinary B2B operating constraints rather than a dedicated CMS licensing regime. The governing layer depends on the adopter’s underlying activity: financial services, telecoms, professional services and data-processing businesses each bring different rulebooks and customer-assurance work. Marketing teams still need to treat business-contact personal data as UK GDPR material. ICO guidance on PECR says electronic-mail consent rules do not apply to corporate subscribers, but senders must identify themselves and provide a valid opt-out route. Live B2B marketing calls require screening against CTPS and TPS, and organisations must not call businesses that have objected.
Further adoption appears likely to be selective rather than broad-based. The clearest fit tends to be suppliers with multi-audience websites, partner channels, frequent product education and enough engineering capacity to justify a decoupled build. More transactional or brochure-led firms may stay with simpler hosted publishing tools, especially where marketing teams own the website without developer support. Migration pressure has been coming from content reuse, localisation and performance expectations, while bundling by broader digital-experience suites may pull some buyers back towards integrated stacks. The market therefore looks less like a universal CMS replacement cycle and more like a specialist choice for firms with complex go-to-market operations.

Key facts
About 9% of the trading cohort reports turnover above £5M (19 of 198 firms) — the rest sits below that revenue band.
8% of the cohort was incorporated since 2022 (16 firms), so a sizeable share is in its first few filing cycles.
This headless CMS accounts for 0.2% (198) of the 84,135 B2B firms with a detectable CMS, a relatively small detected slice within the sector.
London accounts for 43.4% (86) of B2B firms running this headless CMS, with the South East at 14.6% (29) and the North West at 10.6% (21).
SaaS is the largest overlapping sector tag at 26.3% (52), followed by marketing agencies at 15.7% (31) and startups at 10.6% (21).
A tag-management system appears on 43.4% (86) of the cohort, while CDN or security infrastructure appears on 36.9% (73).
B2B direct marketing remains activity-led: ICO guidance links live or automated calls, electronic mail and fax to PECR, with UK GDPR applying when business-contact data is processed.

How Contentful usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling. B2B companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of B2B companies with a detectable system — not of all UK companies.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
Contentful is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
